Research and clinical experi-</p><p>ence are continually expanding our knowl-</p><p>edge, in particular our knowledge of proper</p><p>treatment and drug therapy. Insofar as this</p><p>book mentions any dosage or application,</p><p>readers may rest assured that the authors,</p><p>editors, and publishers have made every</p><p>effort to ensure that such references are in</p><p>accordance with</p><p>the state of knowledge at</p><p>the time of production of the book.</p><p>Nevertheless, this does not involve, imply,</p><p>or express any guarantee or responsibility</p><p>on the part of the publishers in respect to</p><p>any dosage instructions and forms of appli-</p><p>cations stated in the book.</p><p>Every user is re-</p><p>quested to examine carefully</p><p>the manu-</p><p>facturers’ leaflets accompanying each drug</p><p>and to check, if necessary in consultation</p><p>with a physician or specialist, whether the</p><p>dosage schedules mentioned therein or the</p><p>contraindications stated by the manufac-</p><p>turers differ from the statements made in</p><p>the present book. Such examination is</p><p>particularly important with drugs that</p><p>are either rarely used or have been</p><p>newly released on the market. Every dosage</p><p>schedule or every form of application used</p><p>is entirely at the user’s own risk and respon-</p><p>sibility. The authors and publishers request</p><p>every user to report to the publishers any</p><p>discrepancies or inaccuracies noticed.</p><p>Some of the product names, patents, and</p><p>registered designs referred to in this book</p><p>are in fact registered trademarks or propri-</p><p>etary names even though specific reference</p><p>to this fact is not always made in the text.</p><p>Therefore, the appearance of a name with-</p><p>out designation as proprietary is not to be</p><p>construed as a representation by the pub-</p><p>lisher that it is in the public domain.</p><p>This book, including all parts thereof, is</p><p>legally protected by copyright.

Today, both patient</p><p>and physician may be more likely to use the Internet as a first reference source.</p><p>The sheer amount of medical information available on the World Wide Web and</p><p>the speed of its renewal and retrieval may outpace the Caxtonian mechanics of</p><p>printed textbook production, but has done little to erode the authority of the</p><p>printed word. Conversely, in fact, major medical reference texts are these days</p><p>being “ported” into the memory of hand-held electronic devices or on-line data-</p><p>bases. This development, welcomed by gadgetry enthusiasts, eliminates the hefty</p><p>size and weight of the printed tome, but decreases the legibility and convenience</p><p>of the printed page as well as undermining the narrative qualities of the tradition-</p><p>al medical textbook.</p><p>However, another, and only slightly less illustrious tradition has long co-existed</p><p>with that of the major medical opus. This is the “vade mecum,” literally “go with</p><p>me,” intended as a portable tome to be kept on hand for immediate reference. To</p><p>be successful, this format requires authors to possess a high degree of intimacy</p><p>and fluency with their subject matter, to be able to communicate its essentials</p><p>with precision and confidence, compacting prose and condensing content with-</p><p>out sacrificing narrative. The size of the resultant printed volume must be com-</p><p>pact enough to make it easily portable, which nowadays translates as “pocket</p><p>guide.”</p><p>The present pocket guide is a medical vade mecum devoted specifically to the field</p><p>of phytotherapy (herbal medicine), authored by the German physician and phy-</p><p>totherapist Karin Kraft. Prof. Kraft is a member of the Commission E (the official</p><p>expert committee which originally considered the safety and efficacy of phyto-</p><p>medicines in Germany), and is currently a member of the supervising editorial</p><p>board of ESCOP (European Scientific Cooperative on Phytotherapy). ESCOP</p><p>produces the scientific monographs that provide the official core data for herbal</p><p>medicines in the EU.</p><p>In Germany, phytotherapy enjoys a higher degree of integration into general</p><p>medical practice than in any other European country, with physicians regularly</p><p>writing millions of prescriptions for approved phytomedicines on a daily basis. In</p><p>the original German edition of this pocket guide, Prof. Kraft provides the busy-</p><p>general practitioner with a compact and practical reference guide that includes a</p><p>materia medica of herbs, a prescriber for many conditions, and extensive data on</p><p>dosage, forms of administration, safety data and technical standards for German</p><p>commercial herbal products. (Special mention should made of Prof. Kraft’s inclu-</p><p>sion of an often neglected area, that of topical applications of herbal medications</p><p>such as poultices and compresses, more popular in Europe than in the USA).</p><p>In North America, herbal medicine is a more marginal discipline, ultimately the</p><p>legacy of a period of political opposition between medical factions at the turn of</p><p>the 19th century which resulted in the effective outlawing of botanical medical</p><p>practice following the Flexner Report of 1910. Although the majority of “official”</p><p>medicines in the United States Pharmacopoeia were originally botanicals or bo-</p><p>tanically derived, there remains a sharp discontinuity between standard practice</p><p>medicine today and its botanical past. The once widespread schools of physio-</p><p>medical and eclectic botanical medicine were preserved partly through their mi-</p><p>gration to the United Kingdom, where an unbroken tradition today enables qual-</p><p>Foreword</p><p>V</p><p>I</p><p>Fo</p><p>re</p><p>w</p><p>o</p><p>rd</p><p>1</p><p>2</p><p>3</p><p>4</p><p>5</p><p>6</p><p>7</p><p>8</p><p>9</p><p>10</p><p>11</p><p>12</p><p>13</p><p>14</p><p>15</p><p>16</p><p>17</p><p>18</p><p>19</p><p>20</p><p>21</p><p>22</p><p>23</p><p>24</p><p>25</p><p>26</p><p>27</p><p>28</p><p>29</p><p>30</p><p>31</p><p>32</p><p>33</p><p>34</p><p>35</p><p>36</p><p>37</p><p>38</p><p>39</p><p>40</p><p>41</p><p>42</p><p>43</p><p>44</p><p>45</p><p>46</p><p>47</p><p>48</p><p>49</p><p>50</p><p>ified British medical herbalists</p><p>of an experienced health care profession-</p><p>al such as a naturopathic practitioner or herbalist. Many milder teas like gin-</p><p>ger, peppermint, and chamomile have some medicinal qualities, but are usu-</p><p>ally considered safe to use at home with care. The use and sale of many of these</p><p>herb teas fall under the food laws in North America; beverage teas, see p. 479).</p><p>– The concentrations of active principles in medicinal teas are determined by</p><p>the relative proportion of the herbs to extractant (water), the degree of cut-</p><p>ting or grinding of the herb, the recommended water temperature, and the</p><p>steeping time.</p><p>– Disadvantages: It is difficult to determine the exact dosage; combined com-</p><p>ponents may become separated. Cutting or powdering of herbs often dras-</p><p>tically reduces their shelf life by allowing oxygen to reach and degrade ac-</p><p>tive constituents.</p><p>– Suppliers of medicinal teas: Pharmacies, drug stores, health food stores, herb</p><p>shops, and supermarkets.</p><p>– Preparation: Leaves, flowers, and other plant materials are cut coarsely to</p><p>finely. Wood, bark, and root materials are cut finely or pulverized.</p><p>– Storage: Keep dry and store in metal tins or dark jars to prevent direct light</p><p>exposure. The expiration date should be indicated on the label.</p><p>➤ Types of tea preparations</p><p>– Loose tea: Available as single-herb preparations and as tea mixtures. Tea</p><p>mixtures do not usually contain more than seven different plant species.</p><p>Traditional Chinese tea formulas often contain 6 to 15 different herbs.</p><p>Those with as many as 20 to 30 herbs cannot reliably be used to achieve</p><p>selective or specific effects.</p><p>– Tea bags</p><p>• Definition: Small filter bags in which finely chopped herbal teas are en-</p><p>closed.</p><p>• Suitability: All herbs with constituents readily extractable with boiling</p><p>water.</p><p>• Advantages: The small particle size of the tea yields a high degree of ex-</p><p>traction of the constituents. Tea bags are easy to use and ensure uni-</p><p>formity of dose and composition.</p><p>• Disadvantages: Some of the volatile substances are lost during prepara-</p><p>tion and storage and certain constituents undergo oxidation upon expo-</p><p>sure to the air.</p><p>• The individual tea bags should be separately wrapped in airtight pack-</p><p>ets.</p><p>1.4 Herbal Formulations</p><p>16</p><p>Fu</p><p>n</p><p>d</p><p>am</p><p>en</p><p>ta</p><p>ls</p><p>o</p><p>f P</p><p>h</p><p>yt</p><p>o</p><p>th</p><p>er</p><p>ap</p><p>y</p><p>1</p><p>1</p><p>2</p><p>3</p><p>4</p><p>5</p><p>6</p><p>7</p><p>8</p><p>9</p><p>10</p><p>11</p><p>12</p><p>13</p><p>14</p><p>15</p><p>16</p><p>17</p><p>18</p><p>19</p><p>20</p><p>21</p><p>22</p><p>23</p><p>24</p><p>25</p><p>26</p><p>27</p><p>28</p><p>29</p><p>30</p><p>31</p><p>32</p><p>33</p><p>34</p><p>35</p><p>36</p><p>37</p><p>38</p><p>39</p><p>40</p><p>41</p><p>42</p><p>43</p><p>44</p><p>45</p><p>46</p><p>47</p><p>48</p><p>49</p><p>50</p><p>– Instant teas</p><p>• Definition: Tea preparation that readily dissolves in water. Powdered</p><p>teas contain around 8–10 % extractable plant constituents in addition to</p><p>fillers, carriers, flavor enhancers, and colorants (e. g., sugar, dextrin, gel-</p><p>atin, acacia). To prepare tea granules, liquid drug extracts are sprayed</p><p>onto a carrier and dried. Tea granules consist mainly of sugar, with plant</p><p>constituents comprising only 2–3 % of the final product. Many Chinese</p><p>medicinal tea blends are available in this form.</p><p>Note: Diabetics must be aware of the relatively high sugar content. Since</p><p>essential oils are lost during the comminution process, they are some-</p><p>times added at a later phase of the manufacturing process.</p><p>➤ Methods of tea preparations (see also p. 27 )</p><p>– Infusion: Preparation made by pouring boiling water onto the fresh or</p><p>dried herbs and allowing them to steep in order to extract their medicinal</p><p>principles. Suitable for the preparation of delicate or finely chopped herbs</p><p>(leaves, flowers, seeds, bark, and roots) with volatile and thermolabile con-</p><p>stituents (e. g., essential oils).</p><p>– Decoction: Prepared by boiling fresh or dried herbs in water for 10 to 60</p><p>minutes to extract their medicinal principles. Suitable for the preparation</p><p>of hard or very hard plant materials (woods, barks, roots) or herbs with</p><p>sparingly soluble constituents (e. g., silicic acid).</p><p>– Maceration (cold extract): Prepared by allowing a tea herb to steep in cold</p><p>water for several hours to extract its active principles. Suitable for the prep-</p><p>aration of mucilage-containing herbs such as flaxseeds or psyllium seeds</p><p>whose high concentrations of starches and pectins would cause them to ge-</p><p>latinize if prepared with boiling water. Also used to prevent the extraction</p><p>of undesirable constituents that dissolve in hot water.</p><p>1.4 Herbal Formulations</p><p>17</p><p>Fu</p><p>n</p><p>d</p><p>am</p><p>en</p><p>ta</p><p>ls</p><p>o</p><p>f P</p><p>h</p><p>yt</p><p>o</p><p>th</p><p>er</p><p>ap</p><p>y</p><p>1</p><p>1</p><p>2</p><p>3</p><p>4</p><p>5</p><p>6</p><p>7</p><p>8</p><p>9</p><p>10</p><p>11</p><p>12</p><p>13</p><p>14</p><p>15</p><p>16</p><p>17</p><p>18</p><p>19</p><p>20</p><p>21</p><p>22</p><p>23</p><p>24</p><p>25</p><p>26</p><p>27</p><p>28</p><p>29</p><p>30</p><p>31</p><p>32</p><p>33</p><p>34</p><p>35</p><p>36</p><p>37</p><p>38</p><p>39</p><p>40</p><p>41</p><p>42</p><p>43</p><p>44</p><p>45</p><p>46</p><p>47</p><p>48</p><p>49</p><p>50</p><p>➤ Prescription and reimbursement of costs</p><p>– In some European countries, as well as China, properly-prescribed herbal</p><p>preparations are reimbursable by law.</p><p>– In North America, herbal preparations, even when prescribed by a licensed</p><p>practitioner, are not reimbursable by insurance companies or HMOs. This</p><p>is slowly changing, as more research-based evidence of the cost-effective-</p><p>ness of herbal remedies emerges.</p><p>➤ Reading and writing prescriptions</p><p>– The Latin terminology should be used in written prescriptions so that the</p><p>medicinal herb in question can be readily identified at the pharmacy, where</p><p>the drug containers are labeled with the Latin terms.</p><p>– The English and Latin terms for the most important plant parts are listed in</p><p>Table 1.</p><p>English and Latin names and abbreviations of plant parts</p><p>➤ Writing prescriptions for teas, tinctures and other special preparations:</p><p>The prescription must tell the pharmacist how much of which drugs to use,</p><p>which ratio of each drug to use, and so forth.</p><p>➤ Prescription format: The standard Latin abbreviations should be used in writ-</p><p>ten instructions for the pharmacist.

Consumption leading to vomiting was com-</p><p>mon as a means of cleansing the system. This would not be acceptable in</p><p>most technologically developed nations today.</p><p>– In China, a common herb prescription contains from 5 to 10 herbs, and the</p><p>daily dose for each is in the range of 3–12 grams. Many herb tea prescrip-</p><p>tions given for therapeutic use contain about 60 – 200 grams of dried herbs.</p><p>These are to be boiled for up to an hour and 2–3 cups of the strong brew are</p><p>consumed over the course of a day.</p><p>➤ In Germany and other European countries, as well as North America, standard-</p><p>ized extracts are commonly prescribed in tablets and capsules, as well as teas</p><p>and hydroethanolic tinctures. Some standardized extracts are highly concen-</p><p>trated. For instance, Ginkgo biloba leaves are extracted to produce a 50 : 1 con-</p><p>centrate. One part of the finished extract represents the active flavonoids and</p><p>terpenes from 50 parts of the leaves.</p><p>➤ Teas and tinctures in Europe tend to be of lower concentration than in North</p><p>America, and the recommended daily dose also seems to be lower. In Germany</p><p>and Europe, mother tinctures made with an extract ratio of 1 : 10 are often</p><p>favored. This means that 10 parts of the finished tincture represent most of</p><p>the desirable and active constituents from only 1 part of the herb. This is called</p><p>a “mother tincture.” For instance an ounce of echinacea mother tincture made</p><p>at this concentration would represent 1/10 of an ounce of dried echinacea root</p><p>or leaves, or about 3 grams. If the recommended dose were 1–2 mL, 3 times/</p><p>day, the patient would receive the equivalent of about 100–200 mg of dried</p><p>herb, 3 times/day, or up to 600 mg/day. By comparison, a common daily dose</p><p>of Chinese herbs can be up to 200 grams of herbs boiled and consumed as a</p><p>tea. While it has been argued that hydroalcoholic tinctures are more absorb-</p><p>able by the body and so have a stronger impact than teas, the difference would</p><p>be slight compared with the great difference in doses between the two cul-</p><p>tures.</p><p>➤ In North America, as in Europe, standardized extracts are commonly sold and</p><p>prescribed by practitioners. Chinese herb tea and tablet prescriptions are also</p><p>widely used.</p><p>➤ Hydroalcoholic tinctures are usually manufactured at a concentration of any-</p><p>where from 3 : 1 to 10 : 1, and most are around 5 : 1. The recommended dose</p><p>listed on bottles of these tincture products tends to be 20 to 80 drops, several</p><p>times daily.

This has to be determined on the</p><p>basis of a knowledge of the strength of the herb, the strength of the prepara-</p><p>tion, the quality and freshness of the herbs that went into the product, and of</p><p>course the size, weight, age, and needs of the patient.</p><p>➤ In Table 5 , usual German doses are given, along with the usual North American</p><p>dose. We recommend that you adjust the dose within this range of doses, again</p><p>based on the individual situation. Use common sense. Smaller people need a</p><p>smaller dose than a very large person. Young children need a smaller dose than</p><p>an adult. Very young children usually need only a few drops to obtain a thera-</p><p>peutic response. Weak or sensitive individuals need (or can tolerate) a smaller</p><p>dose than a robust, healthy person. Do not think of the dose as static and fixed</p><p>for all circumstances. Use your best judgement, taking account of the situation,</p><p>and always adjust the dose rather than dispensing an herb in the same dose for</p><p>every situation and person.</p><p>➤ In the plant summaries this book maintains the German dosages of the origi-</p><p>nal, however, please refer to the dosage table 337 f for American doses.</p><p>➤ Usually it is best to start a person on a new herb or formula at the minimum</p><p>dose to check for sensitivity and response before going on to a larger dose if no</p><p>response is noted. For long-term use the dose can often be half of the therapeu-</p><p>tic dose as a maintenance dose.</p><p>1.6 Determination of Doses</p><p>21</p><p>G</p><p>en</p><p>er</p><p>al</p><p>G</p><p>u</p><p>id</p><p>el</p><p>in</p><p>es</p><p>fo</p><p>r</p><p>U</p><p>se</p><p>o</p><p>f H</p><p>er</p><p>b</p><p>al</p><p>M</p><p>ed</p><p>ic</p><p>in</p><p>es</p><p>1</p><p>1</p><p>2</p><p>3</p><p>4</p><p>5</p><p>6</p><p>7</p><p>8</p><p>9</p><p>10</p><p>11</p><p>12</p><p>13</p><p>14</p><p>15</p><p>16</p><p>17</p><p>18</p><p>19</p><p>20</p><p>21</p><p>22</p><p>23</p><p>24</p><p>25</p><p>26</p><p>27</p><p>28</p><p>29</p><p>30</p><p>31</p><p>32</p><p>33</p><p>34</p><p>35</p><p>36</p><p>37</p><p>38</p><p>39</p><p>40</p><p>41</p><p>42</p><p>43</p><p>44</p><p>45</p><p>46</p><p>47</p><p>48</p><p>49</p><p>50</p><p>Clinical Applications of Herbal Medicine</p><p>➤ Primary indications</p><p>– Gastrointestinal diseases</p><p>– Colds and flu</p><p>– Liver and gallbladder diseases</p><p>– Psychovegetative diseases</p><p>– Circulatory problems and decreased mental performance</p><p>– Sleep disorders</p><p>– Diseases of the kidney and efferent urinary passages</p><p>– Prostatic diseases</p><p>– Diseases of the female genital tract</p><p>– Varicose veins</p><p>– Convalescent care</p><p>– Prevention of degenerative diseases</p><p>– Supportive (adjuvant) treatment</p><p>➤ Indicated for adjuvant therapy only in</p><p>– Severe diseases</p><p>– Infectious diseases</p><p>– Emergency medicine</p><p>➤ Advantages of herbal medcines</p><p>– Although recent reports highlight a few problems with herb–drug interac-</p><p>tions such as St. John’s wort reducing plasma levels of antirejection and</p><p>antiretroviral drugs, the overall chance of most herbal preparations inter-</p><p>fering with the safety and efficacy of synthetic drugs is small, on the basis</p><p>of actual human reports. Many published comments about herb–drug</p><p>interactions in the literature and popular press involve theoretical inter-</p><p>actions only. More work needs to be performed in this new area of research.</p><p>– Herbal medicines have a wide therapeutic range (the gap between thera-</p><p>peutic and toxic doses is very large) and, thus, a superior risk-to-benefit</p><p>ratio. A number of recent published studies involving thousands of patients</p><p>show that patient reports of adverse effects are close to those reported for</p><p>placebo.</p><p>– Herbal medicines provide a high level of treatment safety.</p><p>– When given a choice, patients with the conditions listed above tend to ac-</p><p>cept them more readily than synthetic drugs, thereby increasing compli-</p><p>ance.</p><p>– Herbal medicines facilitate the transition from acute short-term to chronic</p><p>long-term treatment.</p><p>– Herbal medicines can replace some of the conventional synthetic drugs</p><p>used to treat patients with chronic diseases, such as chronic fatigue syn-</p><p>drome, and multiple morbidity syndromes. This is important because their</p><p>synthetic counterparts often have considerable side effects.</p><p>➤ Disadvantages of herbal medicines</p><p>– Herbal medicines are often not potent enough to treat severe illnesses by</p><p>themselves, except sometimes with a long-term course.</p><p>– Diseases may be drawn out unnecessarily when self-prescribed herbal</p><p>drugs are taken improperly.</p><p>– The improper long-term use of certain herbal preparations, such as the pyr-</p><p>rolizidine alkaloid-containing herb comfrey, can lead to severe side effects.</p><p>2.1 Potentials and Limitations</p><p>22</p><p>G</p><p>en</p><p>er</p><p>al</p><p>G</p><p>u</p><p>id</p><p>el</p><p>in</p><p>es</p><p>fo</p><p>r</p><p>U</p><p>se</p><p>o</p><p>f H</p><p>er</p><p>b</p><p>al</p><p>M</p><p>ed</p><p>ic</p><p>in</p><p>es</p><p>1</p><p>1</p><p>2</p><p>3</p><p>4</p><p>5</p><p>6</p><p>7</p><p>8</p><p>9</p><p>10</p><p>11</p><p>12</p><p>13</p><p>14</p><p>15</p><p>16</p><p>17</p><p>18</p><p>19</p><p>20</p><p>21</p><p>22</p><p>23</p><p>24</p><p>25</p><p>26</p><p>27</p><p>28</p><p>29</p><p>30</p><p>31</p><p>32</p><p>33</p><p>34</p><p>35</p><p>36</p><p>37</p><p>38</p><p>39</p><p>40</p><p>41</p><p>42</p><p>43</p><p>44</p><p>45</p><p>46</p><p>47</p><p>48</p><p>49</p><p>50</p><p>Self-Care Management</p><p>➤ Owing to budget restrictions and the reduced number of drugs covered under</p><p>many health insurance plans, the role of herbal self-treatment is increasing.</p><p>➤ In self-care management, the responsibility for correct herb use and dosage</p><p>lies with the patient.</p><p>➤ As a result, side effects and interactions with other drugs are more likely to go</p><p>unnoticed by these patients.</p><p>➤ It is therefore imperative that all herbs and herbal remedies be accurately la-</p><p>beled with adequate instructions and warnings.</p><p>Ideally, the patient will con-</p><p>sult a qualified health care professional such as a physician trained in herbal</p><p>medicine, trained herbalist, or naturopathic physician before initiating self-</p><p>treatment with any herbal remedy. The advice of a physician should also be</p><p>sought when herbal preparations are used together with pharmaceutical</p><p>drugs, and obviously with severe ailments.</p><p>➤ In North America, according to recent studies, most patients do not inform</p><p>their physician about herbal use. This may be because most medical doctors</p><p>are uninformed about some of the current research regarding the safety and</p><p>efficacy of herbal preparations. This is not surprising, since they rarely receive</p><p>training or continuing education in this area. Perceived disapproval from a</p><p>physician may also play a role in this choice.</p><p>Role of the Physician</p><p>➤ The physician should be informed of the use of herbal remedies to avoid un-</p><p>necessary or excessive treatment and unwanted interactions with synthetic</p><p>drugs (physician-supervised self-care management).</p><p>➤ Since physicians should be able to advise patients about the limitations of self-</p><p>care management, doctors must have a solid knowledge of herbal medicine.</p><p>Patients often tend to be more responsive about informing physicians con-</p><p>cerning herbal use when they feel the physician is knowledgeable and, as far</p><p>as possible, unbiased.</p><p>Note: Not all herbal medicinal products are safe and gentle. The improper long-</p><p>term use of certain herbs can lead to serious side effects. Therefore, herbal rem-</p><p>edies should not be used for extended periods without the supervision of a</p><p>physician or other appropriately experienced health care provider.</p><p>2.1 Potentials and Limitations</p><p>23</p><p>G</p><p>en</p><p>er</p><p>al</p><p>G</p><p>u</p><p>id</p><p>el</p><p>in</p><p>es</p><p>fo</p><p>r</p><p>U</p><p>se</p><p>o</p><p>f H</p><p>er</p><p>b</p><p>al</p><p>M</p><p>ed</p><p>ic</p><p>in</p><p>es</p><p>1</p><p>1</p><p>2</p><p>3</p><p>4</p><p>5</p><p>6</p><p>7</p><p>8</p><p>9</p><p>10</p><p>11</p><p>12</p><p>13</p><p>14</p><p>15</p><p>16</p><p>17</p><p>18</p><p>19</p><p>20</p><p>21</p><p>22</p><p>23</p><p>24</p><p>25</p><p>26</p><p>27</p><p>28</p><p>29</p><p>30</p><p>31</p><p>32</p><p>33</p><p>34</p><p>35</p><p>36</p><p>37</p><p>38</p><p>39</p><p>40</p><p>41</p><p>42</p><p>43</p><p>44</p><p>45</p><p>46</p><p>47</p><p>48</p><p>49</p><p>50</p><p>Preliminary Remarks</p><p>➤ Owing to their low rate of side effects, the use of herbal remedies is increasing</p><p>in certain patient groups, particularly in chronically ill children, pregnant and</p><p>nursing mothers, and senior citizens.</p><p>➤ Certain precautions may be observed when treating allergy sufferers and</p><p>intensive-care patients with herbal remedies.</p><p>Infants and Children</p><p>➤ Pharmacokinetics</p><p>– The pharmacokinetic and pharmacodynamic responses of infants and small</p><p>children to herbal remedies are different from those of adults. As a result,</p><p>the therapeutic range of an herbal drug will also differ in children and</p><p>adults.</p><p>– These differences are attributable to the underdevelopment of organ struc-</p><p>ture and function in children and differences in receptor structures.</p><p>– Drugs are retained longer in a child’s body owing to the lower rates of ex-</p><p>cretion and metabolism.</p><p>➤ Basic rules for treatment of pediatric patients</p><p>– The treatment of pediatric patients with herbal medicinal preparations</p><p>should be carried out under the supervision of a physician and/or other ap-</p><p>propriately experienced health care provider, if the persons who take care</p><p>of the child are not experienced in herbal medicine, or the disease is more</p><p>serious or longer lasting. A herbal remedy suitable for use in children should</p><p>be selected and administered at the lowest dose possible.</p><p>– Generally, the herbal preparation should be administered according to the</p><p>supplier’s recommendation.</p><p>– For preparations without dose recommendation a formula for calculation</p><p>of reduced dosages for children and infants based on body weight may be</p><p>used: children’s dose = (adult dose/110) × (1.5 × weight in kg).</p><p>➤ Practical dosage recommendations for administration of teas (or diluted</p><p>tinctures) to pediatric patients</p><p>– Infants: 5 drops or 1 to 2 droppersful of a tea, or 1 part of tincture (ca. 1 : 5)</p><p>diluted with 10 parts water, several times a day.</p><p>– Children 1 to 5 years: 1 to 2 teaspoons of a tea infusion 3 to 5 times a day (or</p><p>a liquid made by diluting 1 part of tincture with 10 parts of water).</p><p>– Children 6 to 10 years: 1⁄4 to 1⁄3 of the adult dose.</p><p>– Children 11 to ca. 16 years: 1⁄2 of the adult dose.</p><p>– Children over 16 years: Generally the adult dose, but used with greater cau-</p><p>tion.</p><p>– It is important to start with the smallest dose for the first day and work up</p><p>to a higher dose, if no adverse reactions are apparent.</p><p>➤ Administration: Teas, highly diluted alcoholic tinctures, and flavored liquid</p><p>glycerites are preferably used with pediatric patients because they contain low</p><p>doses of the active constituents.</p><p>Note: Instant teas containing saccharose promote the formation of dental</p><p>caries.</p><p>– Alcohol-free herbal preparations, such as flavored glycerites, are preferable</p><p>for pediatric medicine. Liquid herbal remedies often contain alcohol as a</p><p>preservative; the ethanol content must be indicated on the label.</p><p>2.2 Special Patient Groups</p><p>24</p><p>G</p><p>en</p><p>er</p><p>al</p><p>G</p><p>u</p><p>id</p><p>el</p><p>in</p><p>es</p><p>fo</p><p>r</p><p>U</p><p>se</p><p>o</p><p>f H</p><p>er</p><p>b</p><p>al</p><p>M</p><p>ed</p><p>ic</p><p>in</p><p>es</p><p>1</p><p>1</p><p>2</p><p>3</p><p>4</p><p>5</p><p>6</p><p>7</p><p>8</p><p>9</p><p>10</p><p>11</p><p>12</p><p>13</p><p>14</p><p>15</p><p>16</p><p>17</p><p>18</p><p>19</p><p>20</p><p>21</p><p>22</p><p>23</p><p>24</p><p>25</p><p>26</p><p>27</p><p>28</p><p>29</p><p>30</p><p>31</p><p>32</p><p>33</p><p>34</p><p>35</p><p>36</p><p>37</p><p>38</p><p>39</p><p>40</p><p>41</p><p>42</p><p>43</p><p>44</p><p>45</p><p>46</p><p>47</p><p>48</p><p>49</p><p>50</p><p>Note: In Germany, many herbal remedies, even those that have been taken by</p><p>pediatric patients for years without adverse effects, are labeled with state-</p><p>ments such as “Owing to the lack of sufficient scientific data on the use of this</p><p>preparation in children, it should not be used in children under 12 years of</p><p>age”. Such statements are intended to indicate a residual risk. In this case, it is</p><p>important to obtain the advice of a physician in selecting the proper remedy.</p><p>On the other hand, remedies labeled with the statement “Children under 12</p><p>years of age should not take this preparation” are clearly contraindicated in</p><p>pediatric patients. In North America, many preparations are not labeled with</p><p>recommendations for pediatric use, which is why special children’s herbal</p><p>products are increasingly popular. These are mild and pleasant-tasting.</p><p>➤ Value of herbal medicine: The rate of spontaneous healing is much higher in</p><p>infants and children than in adults. This makes it more difficult to assess the</p><p>effectiveness of herbal medicines in pediatric patients.</p><p>Geriatric Patients</p><p>➤ Preliminary remarks: Around 27 % of all individuals over the age of 65 are</p><p>afflicted by one chronic disease, 20 % by two chronic illnesses, and 3 % by three</p><p>or more. In some cases, the symptoms of organ dysfunction precede the clinical</p><p>manifestation of a disease by several years. Many of these patients respond</p><p>well to herbal remedies.</p><p>➤ Pharmacokinetic changes of aging</p><p>– Impairment of blood pH regulation</p><p>– Decreased absorption of oxygen in the blood</p><p>– Decrease in the respiratory rate</p><p>– Decrease in renal and, to a lesser extent, hepatic function</p><p>➤ Basic rules for treatment of geriatric patients</p><p>– Because of their low rates of side effects and interactions with other drugs,</p><p>herbal preparations can be safely and effectively combined with obligatory</p><p>synthetic drugs, with a few exceptions such as St. John’s wort, which should</p><p>be monitored more closely.</p><p>– A lower dose may be needed due to the slower metabolism of geriatric pa-</p><p>tients.</p><p>➤ Value of herbal medicine: Because of the high rate of acceptance by geriatric</p><p>patients, herbal remedies can be a very helpful treatment alternative in this</p><p>patient group.</p><p>➤ Cost: In some cases, herbal preparations are less costly than pharmaceutical</p><p>drugs, despite the fact that insurance plans do not generally pay for them.</p><p>Pregnant and Nursing Mothers</p><p>➤ Pharmacokinetic considerations</p><p>– Drug therapy is always a problematic issue in pregnant and nursing moth-</p><p>ers because of the potential risk of damage to the fetus or infant.</p><p>– Furthermore, it is almost impossible to completely rule out the possibility</p><p>that a given drug may have harmful effects.</p><p>➤ Basic rules for treatment of pregnant and nursing mothers</p><p>– Herbal remedies have a long history of being used to treat pregnant and</p><p>nursing mothers.</p><p>– Warnings indicated on product labels should be interpreted carefully.</p><p>2.2 Special Patient</p><p>Groups</p><p>25</p><p>G</p><p>en</p><p>er</p><p>al</p><p>G</p><p>u</p><p>id</p><p>el</p><p>in</p><p>es</p><p>fo</p><p>r</p><p>U</p><p>se</p><p>o</p><p>f H</p><p>er</p><p>b</p><p>al</p><p>M</p><p>ed</p><p>ic</p><p>in</p><p>es</p><p>1</p><p>1</p><p>2</p><p>3</p><p>4</p><p>5</p><p>6</p><p>7</p><p>8</p><p>9</p><p>10</p><p>11</p><p>12</p><p>13</p><p>14</p><p>15</p><p>16</p><p>17</p><p>18</p><p>19</p><p>20</p><p>21</p><p>22</p><p>23</p><p>24</p><p>25</p><p>26</p><p>27</p><p>28</p><p>29</p><p>30</p><p>31</p><p>32</p><p>33</p><p>34</p><p>35</p><p>36</p><p>37</p><p>38</p><p>39</p><p>40</p><p>41</p><p>42</p><p>43</p><p>44</p><p>45</p><p>46</p><p>47</p><p>48</p><p>49</p><p>50</p><p>• Herbal remedies or preparations that specifically are labeled with the</p><p>statements‚ “Don’t use during pregnancy,” or “Don’t use during breast-</p><p>feeding” should not be used during those times unless under the guid-</p><p>ance of an experienced herbalist or physician with training in herbal</p><p>medicine.</p><p>• Other commercial herbal preparations or herb teas may not be specifi-</p><p>cally labeled “Don’t use during pregnancy or nursing,” but that does not</p><p>imply that they are necessarily safe to use during these times. Bulk herb</p><p>for teas are not often labeled, and some manufacturers may not be ex-</p><p>perienced or knowledgeable enough to label their products appropri-</p><p>ately.</p><p>• In some cases, herbs or herb products have been used safely for centu-</p><p>ries, and sometimes during pregnancy or nursing, but that does not</p><p>mean they are safe. Harmful effects are sometimes subtle and not no-</p><p>ticed, and may be apparent after continued use over time. In general</p><p>herbs and herb products are less likely to be problematic during preg-</p><p>nancy and nursing with occasional use, and it is best to avoid chronic use</p><p>of most herbs during these times.</p><p>• Virtually no herbs have high-quality research demonstrating lack of side</p><p>effects during pregnancy or nursing, rather the use is based on centuries</p><p>of apparently safe use. The other side to this argument is that just be-</p><p>cause an herb hasn’t been proven safe by modern scientific standards</p><p>doesn’t mean that it is probably harmful. Many foods in common use</p><p>have not been thoroughly tested to demonstrate safety with long-term</p><p>use.</p><p>– Herbal medicines that bear warnings such as “Contraindicated during preg-</p><p>nancy ” or “Contraindicated in nursing mothers” clearly should not be used</p><p>by pregnant or nursing mothers. For a complete list of known contraindica-</p><p>tions for herbs during pregnancy and nursing, refer to Botanical Safety</p><p>Handbook by McGuffin et al. (see References, p. 478).</p><p>Allergy Sufferers</p><p>➤ Certain medicinal plants contain allergens that may cause allergic reactions of</p><p>variable severity (even, in rare cases, anaphylactic shock) in individuals with a</p><p>corresponding predisposition. Medicinal plants are capable of triggering type</p><p>I (immediate) and type IV (delayed) allergic reactions.</p><p>➤ The allergenic potency of medicinal plants varies in accordance with the type</p><p>of the plant and the composition of its constituents.</p><p>➤ Cross-sensitivities are a frequent problem.</p><p>Note: Allergy to a given plant does not necessarily mean that the patient will be</p><p>hypersensitive to pharmaceutical preparations made from this plant.</p><p>➤ Type I allergies</p><p>– Pathophysiology: Antibodies of the IgE type start a chain reaction that trig-</p><p>gers the release of different mediators (e. g., histamine).</p><p>– Clinical features</p><p>• Allergic symptoms including allergic conjunctivitis, rhinitis, itching, ur-</p><p>ticaria, Quincke’s edema and allergic asthma as well as cramplike epi-</p><p>gastric complaints accompanied by diarrhea may develop with seconds</p><p>to minutes after exposure. In secondary reactions, they may develop</p><p>within 4 to 6 hours after exposure.</p><p>2.2 Special Patient Groups</p><p>26</p><p>G</p><p>en</p><p>er</p><p>al</p><p>G</p><p>u</p><p>id</p><p>el</p><p>in</p><p>es</p><p>fo</p><p>r</p><p>U</p><p>se</p><p>o</p><p>f H</p><p>er</p><p>b</p><p>al</p><p>M</p><p>ed</p><p>ic</p><p>in</p><p>es</p><p>1</p><p>1</p><p>2</p><p>3</p><p>4</p><p>5</p><p>6</p><p>7</p><p>8</p><p>9</p><p>10</p><p>11</p><p>12</p><p>13</p><p>14</p><p>15</p><p>16</p><p>17</p><p>18</p><p>19</p><p>20</p><p>21</p><p>22</p><p>23</p><p>24</p><p>25</p><p>26</p><p>27</p><p>28</p><p>29</p><p>30</p><p>31</p><p>32</p><p>33</p><p>34</p><p>35</p><p>36</p><p>37</p><p>38</p><p>39</p><p>40</p><p>41</p><p>42</p><p>43</p><p>44</p><p>45</p><p>46</p><p>47</p><p>48</p><p>49</p><p>50</p><p>• Anaphylactic shock usually does not occur unless the allergens are inject-</p><p>ed intravenously.</p><p>– Herbal drugs known to trigger type I allergies</p><p>• Essential oils derived from fennel, ginger, garlic, coriander, caraway</p><p>seed, lovage, balm, pepper, sage, mustard, and various citrus plants are</p><p>important triggers. Because of their ability to cause mucosal irritation,</p><p>they may also enhance other allergies. Inhalation of dust of iris root,</p><p>poke root, mustard, horseradish, castor oil, or linseed may cause rhinitis.</p><p>• Herbal remedies do not play a major role in pollen allergies.</p><p>➤ Type IV allergies</p><p>– Pathophysiology: Mediators of inflammation are released by sensitized T</p><p>lymphocytes.</p><p>– Clinical features: Contact eczema with itching, skin redness, swelling, and</p><p>scaling develops at the site of exposure within 48 to 72 hours.</p><p>– Herbal drugs known to trigger type IV allergies: Low-molecular-weight sec-</p><p>ondary plant chemicals such as coumarins (from parsley family members</p><p>like angelica, clovers like red clover, etc.) and terpenes (from many plant</p><p>families such as ginkgo), as well as flavones and sesquiterpene lactones</p><p>(from composite plants such as feverfew or arnica).</p><p>Intensive Care Patients</p><p>➤ Because of their rapid onset of action and superior dosability, synthetic drugs</p><p>are preferentially used in intensive care medicine. Nonetheless, certain herbal</p><p>drugs are suitable for adjuvant therapy, such as ginger tea or capsules to help</p><p>alleviate nausea.</p><p>➤ Early and effective treatment with herbal remedies with known immunomod-</p><p>ulating effects such as echinacea can reduce the required dose of antibiotics</p><p>and improve wound healing.

Standard herbal</p><p>treatments for various indications are described in Section Four (p. 290 ff.). A</p><p>few basic rules for the use of herbal remedies are presented below.</p><p>Preparation of Teas</p><p>➤ Preparatory measures</p><p>– Tea mixtures: Shake the container holding the tea mixture prior to use to</p><p>ensure the uniform distribution of all components.</p><p>– Herbal teas containing essential oils: The herbs (fruit or seeds such as fennel)</p><p>should not be chopped or crushed until immediately prior to use.</p><p>Note: The caking of hygroscopic preparations such as water-soluble (instant)</p><p>teas makes it impossible to measure the preparation accurately. Therefore,</p><p>the spoon used to remove the tea granules or powder should be completely</p><p>dry and the container should be immediately recapped. In North America, in-</p><p>stant tea powders are mostly available only for Chinese herbs, and most ex-</p><p>tract powders are in capsule or tablet form for ease of use.</p><p>➤ Tea preparation</p><p>– Infusion: Pour boiling water onto the required amount of the herb, cover,</p><p>and allow to steep for 10 to 15 minutes, then strain. A dose of 1 teaspoon</p><p>herb per cup (150 mL) of water is generally recommended.</p><p>– Decoction: Pour cold water onto the required amount of the herb, bring to</p><p>a boil, then cover and allow to simmer for 10 to 15 minutes. Remove from</p><p>heat and allow to stand for a few moments, in some cases up to 10 minutes</p><p>if a slightly stronger preparation is desired, then strain. Several days of tea</p><p>can be stored safely in the refrigerator, then warmed at the time of con-</p><p>sumption. A dose of 1 teaspoon herb preparation per cup (150 mL) of water</p><p>is generally recommended.</p><p>– Maceration (cold extract): Pour cold water onto the comminuted herb. A</p><p>dose of 1 teaspoon herb per cup (150 mL) of water is generally recommend-</p><p>ed. The herb–water mixture is allowed to stand at room temperature for 5</p><p>to 8 hours, stirred occasionally, then strained. Because of the rapid spread</p><p>of bacteria and molds, teas prepared by maceration may be briefly boiled</p><p>before consumption, though the use of sanitary utensils and refrigeration</p><p>of the tea mixture for up to 3 days in the refrigerator makes this mostly un-</p><p>necessary. Make sure utensils are clean.</p><p>➤ Combined forms of preparation</p><p>– Recommended for the preparation of tea mixtures containing certain con-</p><p>stituents that should preferably be extracted</p><p>with cold water and others</p><p>that are best extracted with boiling water.</p><p>– A dose of 1 teaspoon tea mixture per cup of water is generally recommend-</p><p>ed. Half the required amount of water is poured onto the full dose of the tea</p><p>mixture, which is then left to steep for 5 to 8 hours and finally strained. The</p><p>other half of the water is later boiled and poured onto the herbs caught in</p><p>the tea strainer, then added to the cold extract.</p><p>➤ General tips</p><p>– Medicinal teas should be prepared in a non-metallic receptacle such as a</p><p>glass coffeepot or teapot. Teapots with a lid are preferable.</p><p>– The tea should be stirred occasionally while steeping, then pressed against</p><p>the tea strainer when finished.</p><p>2.3 Basics of Administering Herbal Preparations</p><p>28</p><p>G</p><p>en</p><p>er</p><p>al</p><p>G</p><p>u</p><p>id</p><p>el</p><p>in</p><p>es</p><p>fo</p><p>r</p><p>U</p><p>se</p><p>o</p><p>f H</p><p>er</p><p>b</p><p>al</p><p>M</p><p>ed</p><p>ic</p><p>in</p><p>es</p><p>1</p><p>1</p><p>2</p><p>3</p><p>4</p><p>5</p><p>6</p><p>7</p><p>8</p><p>9</p><p>10</p><p>11</p><p>12</p><p>13</p><p>14</p><p>15</p><p>16</p><p>17</p><p>18</p><p>19</p><p>20</p><p>21</p><p>22</p><p>23</p><p>24</p><p>25</p><p>26</p><p>27</p><p>28</p><p>29</p><p>30</p><p>31</p><p>32</p><p>33</p><p>34</p><p>35</p><p>36</p><p>37</p><p>38</p><p>39</p><p>40</p><p>41</p><p>42</p><p>43</p><p>44</p><p>45</p><p>46</p><p>47</p><p>48</p><p>49</p><p>50</p><p>– Teas for colds and flu should be sweetened with honey, whereas those for</p><p>gastrointestinal, liver, and biliary complaints are ideally taken unsweet-</p><p>ened. Use only as much sweetener for these herbs as is necessary to take</p><p>them regularly, because tasting the bitter enhances the therapeutic action.</p><p>Diabetics should use a sugar substitute.</p><p>– Special tea cups with a tight-fitting lid should be used to reduce the loss of</p><p>volatile constituents by evaporation.</p><p>➤ Dosage</p><p>– Adults: 1 teaspoon of herb per 150 mL (5 ounces) of water.</p><p>– Children up to 10 years of age: 1 teaspoon of herb per 250 mL (8 ounces) of</p><p>water.</p><p>– Children up to 1 year of age: 1⁄2 teaspoon of herb per 250 mL of water.</p><p>– Daily dose: 2 to 3 cups per day, sipped slowly.</p><p>Note: General dosage recommendations are provided in this section. The</p><p>specific instructions for use of a given product are found on the product label.</p><p>Certain tea preparations should not be administered to children. The patient</p><p>or guardian should always read the product label and, if uncertain, ask a phar-</p><p>macist or herbalist. Certain medicinal teas can produce side effects when</p><p>overdosed.</p><p>➤ Duration of use</p><p>– Medicinal teas should generally be taken for 4 weeks. Afterwards, the pa-</p><p>tient should discontinue the tea for 4 weeks or switch to another tea with</p><p>similar effects.</p><p>• Exceptions: St. John’s wort or hawthorn teas, which must be used for at</p><p>least 3 months. Many “tonic” teas recommended by a licensed tradition-</p><p>al Chinese medicine practitioner are taken for several months or more,</p><p>depending on the patient’s response, although the formula is often</p><p>changed regularly.</p><p>2.3 Basics of Administering Herbal Preparations</p><p>29</p><p>G</p><p>en</p><p>er</p><p>al</p><p>G</p><p>u</p><p>id</p><p>el</p><p>in</p><p>es</p><p>fo</p><p>r</p><p>U</p><p>se</p><p>o</p><p>f H</p><p>er</p><p>b</p><p>al</p><p>M</p><p>ed</p><p>ic</p><p>in</p><p>es</p><p>1</p><p>1</p><p>2</p><p>3</p><p>4</p><p>5</p><p>6</p><p>7</p><p>8</p><p>9</p><p>10</p><p>11</p><p>12</p><p>13</p><p>14</p><p>15</p><p>16</p><p>17</p><p>18</p><p>19</p><p>20</p><p>21</p><p>22</p><p>23</p><p>24</p><p>25</p><p>26</p><p>27</p><p>28</p><p>29</p><p>30</p><p>31</p><p>32</p><p>33</p><p>34</p><p>35</p><p>36</p><p>37</p><p>38</p><p>39</p><p>40</p><p>41</p><p>42</p><p>43</p><p>44</p><p>45</p><p>46</p><p>47</p><p>48</p><p>49</p><p>50</p><p>Preparation of Wraps and Fomentations</p><p>➤ Herbal compresses, wraps, and fomentations are popular in Europe and other</p><p>countries where herbal preparations are used as part of a traditional healing</p><p>system. Applying herbs or herbal teas externally in this way is safe when a few</p><p>cautions are observed. Local anti-inflammatory effects and stimulation of cir-</p><p>culation and enhanced tissue repair can be expected because of constituents</p><p>such as the gingerols from ginger, which are absorbed transdermally.</p><p>➤ Definition: Wraps are made by winding multiple layers of cloth around an af-</p><p>fected body part. The prepared herbs are placed in the innermost cloth, which</p><p>serves as the carrier. When using fomentations, poultices, and compresses, the</p><p>cloth bearing the herbal preparation is placed in direct contact with the affect-</p><p>ed body part.</p><p>➤ Materials: Natural materials such as cotton, linen, flannel, or wool (e. g., used</p><p>sheets, kitchen towels, diapers, handkerchiefs, gauze compresses, and tow-</p><p>els as well as sheets made of terry cloth, flannel, or moleskin) should be used</p><p>(see Fig. 2). The use of synthetic materials or mixed fabrics is not recom-</p><p>mended.</p><p>– Innermost layer: Cotton or linen</p><p>– Middle layer: Cotton (e. g., terry cloth)</p><p>– Outer layer: Wool, moleskin or cotton (flat sheets, wool blankets, scarves)</p><p>– One or two hot water bottles</p><p>– Fixing material (e. g., adhesive tape, Velcro strips, or safety pins)</p><p>➤ Procedure</p><p>– Preparatory steps: Spread the wrapping materials on a table or countertop</p><p>and prepare the herbs (additive) as recommended on the product label</p><p>(Fig. 3). When the preparation is in place, the patient should be allowed to</p><p>rest without unnecessary distractions.</p><p>➤ Technique</p><p>– The temperature of the wrap is selected in accordance with the type of herb</p><p>used as the additive. It is also important to monitor each patient in accord-</p><p>ance with their age, general health condition, and body temperature.</p><p>– The sheet or packet with the herbal remedy is placed on the body or affected</p><p>body part and covered with a layer of fabric. The body or body part is then</p><p>wrapped in a second, outer layer. The patient should be covered with a</p><p>Fig. 2 Recommended wrap-</p><p>ping materials. Adapted with</p><p>permission from A.

Special attention should be paid to keeping the feet warm</p><p>(place a hot water bottle under the feet, if necessary).</p><p>– To prevent skin burns or irritation, a protective cloth should be placed be-</p><p>tween the skin and the hot water bottle.</p><p>– Duration of effect: The wrapping materials should be applied quickly but</p><p>calmly. The amount of time the wrap should be left on depends on the type</p><p>of wrap used (see Section Four, p. 291 ff.). The patient in the wraps should</p><p>be monitored carefully.</p><p>– Resting period: After the wraps or fomentations have been removed, the pa-</p><p>tient should be allowed to rest for 15 to 20 minutes.</p><p>Note: The herbs used as the additive can be discarded in the normal household</p><p>garbage container, or composted along with kitchen food scraps or yard trim-</p><p>mings. Used herbs should never be reused or consumed.</p><p>Footbaths</p><p>➤ Materials: Wash basin or vessel large enough for the feet to fit in comfortably,</p><p>warm water, and the herbs to be used as the additive.</p><p>➤ Procedure</p><p>– Preparation: Fill the basin or vessel with water heated to the appropriate</p><p>temperature, then add the selected herbal additive (e. g., a tea infusion, es-</p><p>sential oil, sea salt, or mustard flour). The ankle bone should be immersed</p><p>in the water.</p><p>Technique</p><p>– The patient should wear comfortable clothing and sit in a relaxed position.</p><p>If the patient is cold, a light blanket can be placed around the knees.</p><p>– Soaking time: The feet should be soaked for 5 to 20 minutes, depending on</p><p>which type of herb was used as the additive.</p><p>– Afterwards, the feet should be dried with a towel but not rinsed unless mus-</p><p>tard flour was used. Leaving mustard flour on the feet can cause skin necro-</p><p>sis. This can be prevented by rinsing the feet with lukewarm water after the</p><p>footbath.</p><p>– Resting period</p><p>• After the footbath, the patient should put on warm socks and rest for half</p><p>an hour. If preferred, the footbath can be taken at night before retiring.</p><p>• Invigorating footbaths should be taken around noon, and the patient</p><p>should remain mobile afterwards.</p><p>Inhalation</p><p>➤ General remarks: Inhalation is mainly used to treat diseases of the airways.</p><p>This is most easily achieved with steam inhalation.</p><p>➤ Materials:</p><p>Heat-proof vessel, towel, herbal additive.</p><p>➤ Procedure</p><p>– Preparation: Prepare a hot tea infusion or add essential oil to hot water and</p><p>pour into the vessel. Herbal tea infusions, essential oils, or salt-water solu-</p><p>tions can constitute the herbal additive.</p><p>Technique</p><p>– The patient’s head should be held at a comfortable distance above the</p><p>steam. The hair should be covered with a towel to ensure that the vapors</p><p>are trapped between the head and the vessel. The hot vapors should be in-</p><p>haled for 10 to 15 minutes.</p><p>2.4 Working Techniques</p><p>32</p><p>G</p><p>en</p><p>er</p><p>al</p><p>G</p><p>u</p><p>id</p><p>el</p><p>in</p><p>es</p><p>fo</p><p>r</p><p>U</p><p>se</p><p>o</p><p>f H</p><p>er</p><p>b</p><p>al</p><p>M</p><p>ed</p><p>ic</p><p>in</p><p>es</p><p>1</p><p>1</p><p>2</p><p>3</p><p>4</p><p>5</p><p>6</p><p>7</p><p>8</p><p>9</p><p>10</p><p>11</p><p>12</p><p>13</p><p>14</p><p>15</p><p>16</p><p>17</p><p>18</p><p>19</p><p>20</p><p>21</p><p>22</p><p>23</p><p>24</p><p>25</p><p>26</p><p>27</p><p>28</p><p>29</p><p>30</p><p>31</p><p>32</p><p>33</p><p>34</p><p>35</p><p>36</p><p>37</p><p>38</p><p>39</p><p>40</p><p>41</p><p>42</p><p>43</p><p>44</p><p>45</p><p>46</p><p>47</p><p>48</p><p>49</p><p>50</p><p>Body washes</p><p>➤ General comments: The effects of body washes vary in accordance with the</p><p>washing technique, the selected water temperature and the reason for using</p><p>the herbal additive (e. g., to reduce fever, to stop itching, or to reduce sweat-</p><p>ing).</p><p>➤ Materials: Wash basin, towels (at least two), wash cloths, herbal additive (tea</p><p>infusion, essential oil, or bath salts).</p><p>➤ Procedure</p><p>– Preparation: Fill the basin with water heated to the desired temperature</p><p>and place the additive into it. If essential oils are used, it is important to add</p><p>a natural emulsifying agent such as milk, cream, or honey.</p><p>Technique</p><p>– Whole-body washes should always begin with the head and end with the</p><p>feet.</p><p>– To achieve a relaxing effect, the patient should be washed in circular mo-</p><p>tions proceeding in the direction of hair growth and moving away from the</p><p>center of the body.</p><p>– To achieve an invigorating effect, the circular motions should be directed</p><p>against the direction of hair growth and toward the center of the body. This</p><p>procedure stimulates receptors in the hair bulbs and increases central</p><p>lymph and blood volume, both generating a slight arousal reaction.</p><p>– The patient’s skin should not be allowed to cool off during or immediately</p><p>after the washing procedure.</p><p>Note: The additive should be an herb the patient likes to smell and to which</p><p>the patient is not allergic.</p><p>2.4 Working Techniques</p><p>33</p><p>M</p><p>ed</p><p>ic</p><p>in</p><p>al</p><p>P</p><p>la</p><p>n</p><p>ts</p><p>fr</p><p>o</p><p>m</p><p>A</p><p>t</p><p>o</p><p>Z</p><p>2</p><p>1</p><p>2</p><p>3</p><p>4</p><p>5</p><p>6</p><p>7</p><p>8</p><p>9</p><p>10</p><p>11</p><p>12</p><p>13</p><p>14</p><p>15</p><p>16</p><p>17</p><p>18</p><p>19</p><p>20</p><p>21</p><p>22</p><p>23</p><p>24</p><p>25</p><p>26</p><p>27</p><p>28</p><p>29</p><p>30</p><p>31</p><p>32</p><p>33</p><p>34</p><p>35</p><p>36</p><p>37</p><p>38</p><p>39</p><p>40</p><p>41</p><p>42</p><p>43</p><p>44</p><p>45</p><p>46</p><p>47</p><p>48</p><p>49</p><p>50</p><p>Adonis (</p><p>Adonis vernalis</p><p>L.)</p><p>➤</p><p>Synonyms:</p><p>False hellebore; Adonisröschen (Ger.)</p><p>➤</p><p>General comments:</p><p>The aerial plant parts of</p><p>Adonis vernalis</p><p>L. are used in</p><p>medicine.</p><p>➤</p><p>Pharmacology</p><p>–</p><p>Herb:</p><p>Adonis (Adonidis herba).</p><p>–</p><p>Important constituents:</p><p>Flavonoids and steroid cardiac glycosides.</p><p>–</p><p>Pharmacological properties:</p><p>Steroid glycosides have a positive inotropic</p><p>action.</p><p>➤</p><p>Indications</p><p>– Heart failure (NYHA classes I–II)</p><p>– Cardiac arrhythmia</p><p>– Nervous heart disorders</p><p>➤</p><p>Contraindications:</p><p>Pregnant or nursing mothers, children under 12 years of</p><p>age, and individuals hypersensitive to digitaloid drugs should not use adonis.</p><p>➤</p><p>Dosage and duration of use</p><p>–</p><p>Daily dose:</p><p>Mean 0.5 g, maximum 3 g.</p><p>➤</p><p>Adverse effects:</p><p>Vomiting, diarrhea, headache, loss of appetite, gynecomastia.</p><p>Signs of overdose range from mild cardiac arrhythmias to life-threatening ven-</p><p>tricular tachycardia, atrial tachycardia with AV block, stupor, confusion, hallu-</p><p>cinations, impaired vision, depression, and/or psychoses.

Hence, the herb softens the stools and increases the</p><p>volume of the bowel contents.</p><p>➤ Indications: Constipation.</p><p>➤ Contraindications: Bowel obstruction, acute intestinal inflammations, ap-</p><p>pendicitis, abdominal pain of unknown origin. Pregnant or nursing mothers</p><p>should not use buckthorn fruit unless directed by a physician. Use is contra-</p><p>indicated in children under 12 years of age.</p><p>➤ Dosage and duration of use</p><p>– Tea: Steep 4 g (ca. 1 teaspoon) of the chopped herb in 1 cup of boiled water</p><p>for 10 to 15 minutes. Alternatively, place the herb in cold water, boil for 2</p><p>to 3 minutes, then strain immediately.</p><p>• Dosage: One cup in the morning and at night.</p><p>– Daily dose: 2–5 g.</p><p>– As a rule, the minimum dose required to soften the stools should be used,</p><p>and continuous use of the herb should be restricted to only a few days.</p><p>➤ Adverse effects: The laxative effect of the herb can lead to cramplike gastro-</p><p>intestinal complaints. Long-term use can result in the loss of electrolytes, par-</p><p>ticularly potassium ions, thereby leading to problems such as hyper-</p><p>aldosteronism and decreased bowel motility. Arrhythmias, nephropathies,</p><p>edemas, and accelerated bone degeneration are rare side effects. Consumption</p><p>of large quantities of buckthorn fruit can lead to diarrhea with vomiting and</p><p>kidney irritation.</p><p>➤ Herb–drug interactions: Owing to its laxative effect, buckthorn fruit can im-</p><p>pair the absorption of pharmaceutical drugs or herbal preparations containing</p><p>potentially toxic or life-sparing constituents such as cardiac glycosides (i. e.,</p><p>Digitalis spp.) if taken concomitantly.</p><p>Warning: Chronic use or abuse of the herb can increase the potency of car-</p><p>diac glycosides and diuretics owing to the resulting potassium deficiency.</p><p>➤ Summary assessment: Buckthorn fruit and other herbs containing anthra-</p><p>noids should not be used to treat chronic constipation.</p><p>✿ Literature</p><p>– Monographs: DAB 1998; Commission E</p><p>– Scientific publications: see p. 478; Anon: Abwehr von Arzneimittelrisiken,</p><p>Stufe II.

The British model is</p><p>distinct again from the German experience and emphasizes the importance of</p><p>understanding different cultural and national expressions of traditional herbal</p><p>medicine, education, and practice.</p><p>Sensitive to such cultural variations, Thieme wisely enlisted the aid of Christopher</p><p>Hobbs, a fourth-generation American herbalist, to help render the translation of</p><p>Prof. Kraft’s German text into the US cultural context. Hobbs, one of the most</p><p>highly regarded herbal practitioners in the US, addressed this challenging task by</p><p>reviewing every line of the text. Hobbs has replaced some herbs in the materia</p><p>medica, suggested more appropriate local equivalents for herbal products, and</p><p>annotated bi-cultural comments where relevant. He has also rewritten doses into</p><p>the typically higher US forms. Meanwhile, Hobbs has deftly preserved the nu-</p><p>ances of the German text; Prof. Kraft actively participated in, and agreed to, all the</p><p>changes. The result of this bi-cultural collaboration is an almost seamless repre-</p><p>sentation of the German original harmonized to the North American audience.</p><p>As more physicians in this country recognize the need to investigate the CAM</p><p>(complementary and alternative medicine) modalities that are being espoused by</p><p>many of their patients, a premium is inevitably placed upon reliable sources of</p><p>data and clinical information about CAM. Botanical medicines in particular have</p><p>sadly been the subject of excessive amounts of published secondary and tertiary</p><p>“information” devoid of clinical context, and largely irrelevant to the primary care</p><p>provider. By contrast, Karin Kraft and Christopher Hobbs present us with a suc-</p><p>cinct and authoritative survey of herbal medicine that is accessible to the physi-</p><p>cian and can readily be applied to everyday clinical practice. The “pocket guide”</p><p>represents a unique cross-cultural and trans-disciplinary blend of reliable, accu-</p><p>rate, and accessible information about phytotherapy; it is a mini-masterpiece of</p><p>integrative medicine.</p><p>March 2004 Jonathan Treasure</p><p>Medical Herbalist</p><p>Ashland, Oregon, USA</p><p>Foreword</p><p>V</p><p>II</p><p>P</p><p>re</p><p>fa</p><p>ce</p><p>1</p><p>2</p><p>3</p><p>4</p><p>5</p><p>6</p><p>7</p><p>8</p><p>9</p><p>10</p><p>11</p><p>12</p><p>13</p><p>14</p><p>15</p><p>16</p><p>17</p><p>18</p><p>19</p><p>20</p><p>21</p><p>22</p><p>23</p><p>24</p><p>25</p><p>26</p><p>27</p><p>28</p><p>29</p><p>30</p><p>31</p><p>32</p><p>33</p><p>34</p><p>35</p><p>36</p><p>37</p><p>38</p><p>39</p><p>40</p><p>41</p><p>42</p><p>43</p><p>44</p><p>45</p><p>46</p><p>47</p><p>48</p><p>49</p><p>50</p><p>The use of medicinal plants to treat everyday complaints and illnesses is becom-</p><p>ing ever more popular.

This pocket guide is based on expe-</p><p>riences and prescriptions that have been used in Germany for many years or even</p><p>decades. If necessary, they have been supplemented by US-American remedies</p><p>and suggestions for use. Where possible, available scientific literature has also</p><p>been taken into account. The book includes the medicinal plants most widely used</p><p>in Germany, almost all of which are also used in the US, as well as their use in the</p><p>treatment of major syndromes. A general section in which production processes,</p><p>quality characteristics, and legal backgrounds are explained is followed by</p><p>portraits of the most important medicinal plants with references to more recent</p><p>scientific literature. Illnesses and possibilities of treating them with medicinal</p><p>plant preparations as well as a critical evaluation of the significance of this thera-</p><p>py make up the next section. A specialty of this checklist is the section “Care In-</p><p>volving Medicinal Plants.” Here special value was attached to practicability. A tab-</p><p>ular section divided up into medicinal plants with brief summaries of remedies</p><p>and references follows. Contact addresses and lists of manufacturers as well as a</p><p>comprehensive table of contents round off the guide.</p><p>Dr. Liane Platt-Rohloff and Ms Angelika-M. Findgott from Thieme International</p><p>have done a first-class job of coordinating the work of both authors and editing</p><p>the manuscripts.

Roasted</p><p>coffee beans contain many aroma substances due to the pyrolysis of carbo-</p><p>hydrates, proteins, fats, and aromatic acids.</p><p>– Pharmacological properties: The stimulatory effect of caffeine sets in within</p><p>a few minutes after administration. Most of the effects specified for coffee</p><p>are attributable to the action of caffeine.</p><p>• Effects of caffeine: Caffeine has positive inotropic effects and, when ad-</p><p>ministered in high doses, exerts a positive chronotropic effect on the</p><p>heart and stimulates the central nervous system. It relaxes the smooth</p><p>muscles of the blood vessels (except in the brain, where it causes vaso-</p><p>constriction) and bronchi. Caffeine has short-term diuretic effects, stim-</p><p>ulates the secretion of gastric juices, and increases the release of</p><p>catecholamines.</p><p>• Cardiovascular effects: Individuals who normally do not drink coffee ex-</p><p>hibit an average 10 mmHg increase in systolic blood pressure within</p><p>1 hour of administration of 250 mg of caffeine. Habitual coffee drinkers</p><p>are tolerant to this dose.</p><p>• An average dose of 5 to 6 cups of coffee per day (made by steeping the</p><p>herb in boiling water for 10 minutes) for 9 weeks significantly increases</p><p>the total cholesterol and LDL cholesterol levels in serum. The use of filter</p><p>paper can reduce this effect by 80 %.</p><p>Plant Summaries—C</p><p>51</p><p>M</p><p>ed</p><p>ic</p><p>in</p><p>al</p><p>P</p><p>la</p><p>n</p><p>ts</p><p>fr</p><p>o</p><p>m</p><p>A</p><p>t</p><p>o</p><p>Z</p><p>2</p><p>1</p><p>2</p><p>3</p><p>4</p><p>5</p><p>6</p><p>7</p><p>8</p><p>9</p><p>10</p><p>11</p><p>12</p><p>13</p><p>14</p><p>15</p><p>16</p><p>17</p><p>18</p><p>19</p><p>20</p><p>21</p><p>22</p><p>23</p><p>24</p><p>25</p><p>26</p><p>27</p><p>28</p><p>29</p><p>30</p><p>31</p><p>32</p><p>33</p><p>34</p><p>35</p><p>36</p><p>37</p><p>38</p><p>39</p><p>40</p><p>41</p><p>42</p><p>43</p><p>44</p><p>45</p><p>46</p><p>47</p><p>48</p><p>49</p><p>50</p><p>➤ Indications</p><p>– Migraine headaches</p><p>– Decreased performance</p><p>➤ Contraindications: None known.</p><p>➤ Dosage and duration of use: Daily dose: 15 g of the herb.</p><p>➤ Adverse effects: Doses of up to 500 mg of caffeine (= 5 cups of coffee) per day</p><p>are toxicologically safe for healthy adults who are habitual coffee drinkers. Pa-</p><p>tients with cardiovascular lability, kidney diseases, hyperthyroidism, a predis-</p><p>position to convulsions, and certain psychiatric disorders (e. g., panic attacks)</p><p>should use the herb cautiously.</p><p>– Side effects (attributable to coffee’s chlorogenic acid content) include gas-</p><p>tric hyperacidity, gastric irritation, diarrhea, and reduced appetite. Vomit-</p><p>ing and abdominal cramps are signs of poisoning. Pregnant and nursing</p><p>mothers should avoid caffeine. The maximum safe daily dose should not</p><p>exceed 300 mg (equivalent to 3 cups of coffee).</p><p>– Caffeine can cause mental and physical dependence. Signs of withdrawal</p><p>include headaches and sleep disorders.</p><p>Important: The prolonged administration of more than 1.5 g of caffeine per</p><p>day is often observed to lead to unspecific symptoms such as restlessness,</p><p>irritability, insomnia, palpitation, dizziness, vomiting, diarrhea, lack of ap-</p><p>petite, and headaches.

Some are used to make</p><p>fabrics, whereas others are used to produce flaxseed oil, a valuable foodstuff</p><p>and medicinal product.</p><p>➤ Pharmacology</p><p>– Herb: Flaxseed (Lini semen). The herb consists of the ripe, dried seeds of</p><p>Linum usitatissimum and preparations of the same.</p><p>– Important constituents: 3–10 % mucilage (arabinoxylans, galactans, rham-</p><p>nogalacturonans), cyanogenetic glycosides (0.05–0.1 %), and 10–45 % fatty</p><p>oil (linolenic acid, 40–70 %; linoleic acid, 10–25 %; oleic acid, 13–30 %).</p><p>– Pharmacological properties: Linseed has laxative action due to its fiber and</p><p>mucilage components. Linseed lowers the cholesterol concentration in the</p><p>liver of animals. Prussic acid is not produced from the cyanogenetic acids.</p><p>➤ Indications</p><p>– Constipation</p><p>– Gastritis</p><p>– Enteritis</p><p>– Skin irritations</p><p>➤ Contraindications: Bowel obstruction, esophageal stenosis or narrowing of</p><p>the gastrointestinal tract and acute inflammatory diseases of the bowel, eso-</p><p>phagus, or cardia.</p><p>➤ Dosage and duration of use</p><p>– Internal use</p><p>• Constipation: One tablespoon of whole or crushed flaxseed, 2 to 3 times</p><p>a day, in two 6-ounce glasses of water (at least 150 mL).</p><p>• Gastritis, enteritis: Flaxseed gruel prepared using 2 to 3 tablespoons of</p><p>ground or chopped flaxseed.</p><p>– External use (poultices): For inflammatory skin diseases, prepare a gruel made</p><p>by mixing 125 g of flaxseed meal with 1 cup of water and wrap in a suitable</p><p>cloth. Apply a hot, wet poultice to the affected area of the skin twice daily.</p><p>Plant Summaries—F</p><p>67</p><p>M</p><p>ed</p><p>ic</p><p>in</p><p>al</p><p>P</p><p>la</p><p>n</p><p>ts</p><p>fr</p><p>o</p><p>m</p><p>A</p><p>t</p><p>o</p><p>Z</p><p>2</p><p>1</p><p>2</p><p>3</p><p>4</p><p>5</p><p>6</p><p>7</p><p>8</p><p>9</p><p>10</p><p>11</p><p>12</p><p>13</p><p>14</p><p>15</p><p>16</p><p>17</p><p>18</p><p>19</p><p>20</p><p>21</p><p>22</p><p>23</p><p>24</p><p>25</p><p>26</p><p>27</p><p>28</p><p>29</p><p>30</p><p>31</p><p>32</p><p>33</p><p>34</p><p>35</p><p>36</p><p>37</p><p>38</p><p>39</p><p>40</p><p>41</p><p>42</p><p>43</p><p>44</p><p>45</p><p>46</p><p>47</p><p>48</p><p>49</p><p>50</p><p>➤ Adverse effects: Bowel obstruction can occur when large quantities of flax-</p><p>seed are used to treat constipation without an adequate intake of fluids. The</p><p>cyanogenetic glycosides do not pose a health risk. Some commercial flaxseeds</p><p>have been identified in the past that contain levels of cadmium beyond recom-</p><p>mended government limits. This should be considered during chronic use of</p><p>flaxseed.</p><p>➤ Herb–drug interactions: Flaxseed can impair the absorption of pharmaceuti-</p><p>cal drugs or herbal preparations containing very potent constituents such as</p><p>cardiac glycosides (i. e. Digitalis spp.) if taken concomitantly.</p><p>➤ Summary assessment: Flaxseed is an herbal laxative that is also suitable for</p><p>treatment of chronic constipation. It has a very low rate of side effects and does</p><p>not interfere with the physiology of the bowels.</p><p>✿ Literature</p><p>– Monographs: ESCOP; Commission E</p><p>– Scientific publications: see p. 478.</p><p>Frangula (Rhamnus frangula L.)</p><p>➤ Synonyms: Alder buckthorn, black alder; Faulbaum (Ger.)</p><p>➤ Pharmacology</p><p>– Herb: Frangula bark (Frangulae cortex). The herb consists of the dried bark</p><p>of branches and twigs of Rhamnus frangula L. (Frangula alnus Miller)</p><p>Important: Since fresh Frangula bark can induce nausea, the drug must be</p><p>stored for one year before use.</p><p>– Important constituents: Anthraquinone derivatives (4–6 %), including an-</p><p>thranoids, glucofrangulin A and B, and frangulins A, B and C.</p><p>– Pharmacological properties: Anthraquinones promote the active secretion</p><p>of electrolytes and water into the intestinal lumen while simultaneously</p><p>inhibiting their absorption from the intestine. The liquefaction of the bowel</p><p>contents leads to an increase in intestinal filling pressure. Stimulation of</p><p>intestinal peristalsis also occurs.</p><p>➤ Indications: For short term treatment of occasional constipation.</p><p>➤ Contraindications: Bowel obstruction, acute inflammation of the bowels, ap-</p><p>pendicitis. Frangula bark should not be used by children under 10 years of age</p><p>or by pregnant or nursing mothers.</p><p>➤ Dosage and duration of use</p><p>– Tea: Steep 2 g of the finely chopped dried bark in 150 mL of boiled water for</p><p>15 minutes.</p><p>• Dosage: One cup in the morning and evening.

In animals, bilobalide and ginkgolides</p><p>were found to improve the flow capacity of the blood by lowering viscosity,</p><p>inactivating toxic oxygen radicals and improving the circulation in cerebral</p><p>and peripheral arteries. The herb inhibits the development and promotes</p><p>the elimination of cerebral edema, improves the utilization of ATP and glu-</p><p>cose, and stabilizes the cell membranes. Clinical, controlled double-blind</p><p>studies in humans have confirmed the results of animal experiments (gink-</p><p>go was found to improve the memory capacity and microcirculation and</p><p>reduce the viscosity of plasma).</p><p>➤ Indications</p><p>– Several small studies found a moderate benefit when using Ginko for ver-</p><p>tigo (dizziness) and tinnitus of vascular and involutional origin.</p><p>– Circulatory disorders (peripheral artery occlusion, especially intermittent</p><p>claudication, for which some controlled studies reported a benefit).</p><p>– Memory enhancement in younger people or people with no preexisting</p><p>memory impairment has been suggested, with both positive and negative</p><p>recent clinical trials, but this remains controversial.</p><p>– For symptomatic treatment of cerebro-organic impairment of mental per-</p><p>formance. (Controlled studies showed modest, but statistically significant</p><p>positive results for cerebral insufficiency. Several reports have indicated</p><p>modest benefit in controlled studies for Alzheimer’s and non-Alzheimer’s</p><p>dementia.)</p><p>➤ Contraindications: Hypersensitivity to ginkgo preparations.</p><p>➤ Dosage and duration of use</p><p>– For decreased mental performance: Oral daily dose: 120–240 mg of a spe-</p><p>cially formulated, standardized Ginkgo biloba extract (GBE; 24 % flavone</p><p>glycosides, 6 % terpenoids), divided into 2 to 3 portions, to be taken for a</p><p>period of at least 12 weeks. Thereafter, treatment should be continued after</p><p>a positive assessment result.</p><p>– For peripheral artery occlusion, vertigo, and tinnitus: 120–160 mg GBE per</p><p>day. Used for 6 to 8 weeks for treatment of vertigo and tinnitus; longer use</p><p>is only justified if some improvement can be registered. According to some</p><p>studies use for at least 3 months is necessary for full effect.</p><p>➤ Adverse effects: Mild gastrointestinal complaints, headaches, and allergic re-</p><p>actions are very rare side effects.</p><p>➤ Herb–drug interactions: May potentiate anticoagulant activity of aspirin,</p><p>warfarin, heparin, and other similar drugs.</p><p>Warning: Caution may be indicated during the perioperative period (see</p><p>Herb–drug interactions).</p><p>➤ Summary assessment: Ginkgo is an herb with a number of positive and well-</p><p>designed clinical trials, especially for improving symptoms of dementia in the</p><p>Plant Summaries—G</p><p>73</p><p>M</p><p>ed</p><p>ic</p><p>in</p><p>al</p><p>P</p><p>la</p><p>n</p><p>ts</p><p>fr</p><p>o</p><p>m</p><p>A</p><p>t</p><p>o</p><p>Z</p><p>2</p><p>1</p><p>2</p><p>3</p><p>4</p><p>5</p><p>6</p><p>7</p><p>8</p><p>9</p><p>10</p><p>11</p><p>12</p><p>13</p><p>14</p><p>15</p><p>16</p><p>17</p><p>18</p><p>19</p><p>20</p><p>21</p><p>22</p><p>23</p><p>24</p><p>25</p><p>26</p><p>27</p><p>28</p><p>29</p><p>30</p><p>31</p><p>32</p><p>33</p><p>34</p><p>35</p><p>36</p><p>37</p><p>38</p><p>39</p><p>40</p><p>41</p><p>42</p><p>43</p><p>44</p><p>45</p><p>46</p><p>47</p><p>48</p><p>49</p><p>50</p><p>elderly.

C.)</p><p>➤ General comments: Many species of hawthorn are distributed throughout the</p><p>moderate zones of the Northern Hemisphere. The use of its leaves and flowers</p><p>as a remedy for heart disorders dates back to the nineteenth century.</p><p>➤ Pharmacology</p><p>– Herb: Hawthorn leaf and flower (Crataegi folium cum flore). The herb con-</p><p>sists of the leaves and flowers of Crataegus laevigata DC. or, less frequently,</p><p>of other hawthorn species.</p><p>– Important constituents: Flavonoids (1.8 %) such as hyperoside (0.28 %), rutin</p><p>(0.17 %), and vitexin (0.2 %), and oligomeric procyanidins (2–3 %).</p><p>– Pharmacological properties: The procyanidins and flavonoids in hawthorn</p><p>determine its therapeutic action. These substances effect an increase in cor-</p><p>onary blood flow and dilate the blood vessels, thereby enhancing myocar-</p><p>dial circulation and perfusion. The herb has positive inotropic, chronotropic</p><p>and dromotropic effects, and improves the tolerance to hypoxia. The cardio-</p><p>tropic effects of Crataegus are attributed to an increase in the membrane</p><p>permeability to calcium ions and an increase in the intracellular cyclic AMP</p><p>concentration. Altogether, this makes the heart work more economically.</p><p>➤ Indications</p><p>– Supportive treatment for heart failure (NYHA</p><p>class I–II)</p><p>– As a strengthening tonic for prevention of heart irregularities and conges-</p><p>tive heart failure</p><p>➤ Contraindications: None known.</p><p>➤ Dosage and duration of use</p><p>– Daily dose: 3.5–19.8 mg flavonoids, calculated as hyperoside (DAB 10), or</p><p>160–900 mg extract (4 : 1 to 7 : 1 with ethanol 45 % v/v or methanol 70 %</p><p>v/v), corresponding to 30–168.7 mg oligomeric procyanidins, calculated as</p><p>epicatechol. Hawthorn leaf/flower can be used for unlimited periods.</p><p>➤ Adverse effects: There are no known health hazards or side effects in conjunc-</p><p>tion with proper administration of the designated therapeutic doses of the</p><p>herb.</p><p>➤ Herb–drug interactions: None known.</p><p>➤ Summary assessment: Clinical studies demonstrating the efficacy of haw-</p><p>thorn leaf/flower in NYHA class I–II heart failure are available.</p><p>✿ Literature</p><p>– Monographs: DAB 1998; ESCOP; Commission E</p><p>– Scientific publications: see p. 478; Bahorun T, Gressier B, Trotin F et al:</p><p>Oxygen species scavenging activity of phenolic activities, fresh plant organs</p><p>and pharmaceutical preparations.

medicine.</p><p>➤ Pharmacology</p><p>– Herb: Horse chestnut seed (Hippocastani semen). The herb consists of the</p><p>dried seeds of Aesculus hippocastanum L. and preparations of the same.</p><p>– Important constituents: Aescin is the most important constituent. Triter-</p><p>pene saponins (3–5 %) and flavonoids are also present.</p><p>– Pharmacological properties: Horse chestnut extract was found to be anti-</p><p>exudative and reduce capillary wall permeability, leading to an overall anti-</p><p>edematous effect. Clinical data on the venotonic effects are available. In</p><p>humans, the herb significantly reduces transcapillary filtration. Oral appli-</p><p>cation was found to significantly improve the symptoms of chronic venous</p><p>insufficiency in double-blind studies. It was found to significantly reduce</p><p>leg edemas, similarly to the results of compression treatments.</p><p>➤ Indications</p><p>– Complaints associated with chronic venous insufficiency</p><p>– Posttraumatic or postoperative soft-tissue swelling</p><p>➤ Contraindications: None known.</p><p>➤ Dosage and duration of use: Daily dose should be equivalent to 100 mg of</p><p>aescin.</p><p>➤ Adverse effects: Inflammation of the mucous membranes in the gastrointes-</p><p>tinal tract can occur as a rare side effect after internal use.</p><p>➤ Herb–drug interactions: None known.</p><p>Important: Ointments containing aescin should not be rubbed vigorously onto</p><p>the skin, but applied gently. They might otherwise cause or worsen phlebitis.</p><p>Important: High-dose horse-chestnut formulations should not be used in the</p><p>last two trimesters of pregnancy or when nursing a baby unless absolutely nec-</p><p>essary.</p><p>➤ Summary assessment: Horse chestnut seed is an effective and clinically well-</p><p>researched herbal medicament.

The</p><p>native Polynesians use the rhizome to make a mildly intoxicating beverage.</p><p>Kava rhizome extract has anxiolytic and sedative effects.</p><p>➤ Pharmacology</p><p>– Herb: Kava rhizome (Piperis methystici rhizoma). The herb consists of the</p><p>peeled, cut and dried rhizomes (usually with the root parts removed) of Pip-</p><p>er methysticum G. F. and preparations of the same.</p><p>– Important constituents: Kava lactones (kava pyrones, 5–12 %) consisting</p><p>mainly of (+)-kavain (1.8 %), (+)-methysticin (1.2 %), desmethoxyyangonin</p><p>(1 %), and yangonin (1 %).</p><p>– Pharmacological properties: Kava pyrones have sedative and central muscle</p><p>relaxant effects. Anticonvulsive, neuroprotective, narcosis-enhancing, cen-</p><p>tral muscle relaxant, spasmolytic, analgesic, and local anesthetic effects</p><p>were observed in animals. The herb has anxiolytic and soporific effects in</p><p>humans.</p><p>➤ Indications: Nervous tension, states of tension and anxiety.</p><p>➤ Contraindications: Pregnancy, breast feeding, and endogenous depression</p><p>(increased risk of suicide). The herb should not be taken for more than 3</p><p>months without the advice of a qualified health care practitioner.</p><p>➤ Dosage and duration of use</p><p>– Daily dose: 60–120 mg of herb preparations.</p><p>➤ Adverse effects: The prolonged use of high doses of kava can, in rare cases, lead</p><p>to gastrointestinal complaints, oculomotor equilibrium disorders, pupil dila-</p><p>tion, and insufficiency of accommodation. Slight morning fatigue can occur in</p><p>the initial phase of treatment. Disorders of complex movement with otherwise</p><p>unimpaired consciousness are initial signs of overdose, followed by fatigue</p><p>and a tendency to fall asleep. Kava increases the action of substances that affect</p><p>the central nervous system, e. g., alcohol, barbiturates, and other psychoactive</p><p>drugs. A few studies yielded some indication of hepatotoxicity in relation to</p><p>administration of kava. Though this information is limited to date and still</p><p>awaits scientific evaluation, it is recommended to consider the following when</p><p>using kava products.</p><p>Warning: Kava should not be taken on a daily basis for more than 4 weeks.</p><p>Warning: Use of kava should be discontinued if symptoms of jaundice</p><p>appear.</p><p>Warning: Patients with a history of liver problems or who suspect possible</p><p>liver problems or who are taking pharmaceutical drugs should use kava</p><p>only with the advice of a professional health care provider.</p><p>Warning: See p. 212 for cautions in the use of kava in disorders of the ner-</p><p>vous system.</p><p>➤ Herb–drug interactions: Kava should not be used by anyone who has liver</p><p>problems, is taking any drugs with known adverse effects on the liver, such as</p><p>NSAIDS, or is a regular consumer of alcohol.</p><p>➤ Summary assessment: Kava is an effective herb in the specified indications</p><p>(herbal tranquilizer).

Gaertn.)</p><p>➤</p><p>Synonyms: Marian thistle; Mariendistel (Ger.)</p><p>➤ General comments: The milk thistle is a native European medicinal plant that</p><p>has been used since ancient times. It has striking deep green leaves with white</p><p>spots along the veins.</p><p>➤ Pharmacology</p><p>– Herb: Milk thistle fruit (Cardui mariae herba). The herb consists of the</p><p>pappus-free, ripe fruit of Silybum marianum (L.) G.</p><p>– Important constituents: Silymarin (flavonolignan mixture, 1.5–3 %), primary</p><p>components silybin A and B (combination of the two is called silibinin), iso-</p><p>silybin A, isosilybin B, silychristin, silydianin, flavonoids (apigenin, chryso-</p><p>eriol, eriodictyol, naringenin, quercetin, taxifolin), and fatty oil (20–30 %).</p><p>– Pharmacological properties: Silymarin and silibinin were found to have</p><p>hepatoprotective effects in studies on liver damage. Silymarin stimulates</p><p>RNA polymerase I in the nucleus of hepatocytes. This, in turn, increases the</p><p>rate of ribosomal protein synthesis and enhances the regenerative capacity</p><p>of the liver. Silymarin is an effective antidote for Amanita mushroom poi-</p><p>soning because it antagonizes the inhibition of RNA polymerase I by</p><p>α-amanitine. The herb also has weak cholagogic properties.</p><p>➤ Indications</p><p>– Dyspeptic complaints</p><p>– Liver and gallbladder complaints</p><p>➤ Contraindications: None known.</p><p>➤ Dosage and duration of use</p><p>– Daily dose: 200–400 mg silymarin based on the silibinin content (usually</p><p>80 %) in a divided dose, around mealtimes.</p><p>➤ Adverse effects: None known.</p><p>➤ Herb–drug interactions: None known.</p><p>➤ Summary assessment: Milk thistle is used to treat dyspeptic complaints. It</p><p>should be used in combination with other gallbladder remedies. The hepato-</p><p>protective effects should be confirmed in modern clinical trials.</p><p>✿ Literature</p><p>– Monographs: DAB 1998; Commission E</p><p>– Scientific publications: see p. 478; Lorenz D, Mennicke WH, Behrendt W:</p><p>Untersuchungen zur Elimination von Silymarin bei cholecystektomierten</p><p>Patienten.

Its berries were first introduced to contemporary herbal</p><p>medicine towards the beginning of the twentieth century.</p><p>➤ Pharmacology</p><p>– Herb: Saw palmetto fruit (Sabal fructus, Serenoae repentis fructus). The</p><p>herb consists of the ripe, dried fruit of Serenoa repens (B.) S. (syn. Sabal ser-</p><p>rulata [M] N. et S.) and preparations of the same.</p><p>– Important constituents: Steroids (β-sitosterol and its glucosides), flavo-</p><p>noids, water-soluble polysaccharides, and a fatty oil consisting of 80 % lau-</p><p>ric, myristic, and oleic acids, two-thirds of which are present as free fatty</p><p>acids.</p><p>– Pharmacological properties: In animals, lipophilic saw palmetto fruit ex-</p><p>tracts inhibited testosterone production at the cytosol receptors, thus caus-</p><p>ing significant inhibition of prostatic growth. Owing to its β-sitosterol con-</p><p>tent, it increases the uterine weight of female mice after injection. Saw</p><p>palmetto extracts have antiandrogenic and antiestrogenic effects. Li-</p><p>pophilic extracts of the herb induce spasmolysis of the smooth muscles of</p><p>organs. The extract was found to have antiexudative and decongestive ef-</p><p>fects in animals and also promotes the degradation of prostaglandins and</p><p>leukotrienes. Saw palmetto improves the urinary flow rate and reduces the</p><p>residual urine volume in patients with grades I and II of prostatic hyperpla-</p><p>sia (Alken).</p><p>➤ Indications</p><p>– Urinary tract infections</p><p>– Benign prostatic hyperplasia grades I and II</p><p>➤ Contraindications: None known.</p><p>➤ Dosage and duration of use</p><p>– Daily dose: 1–2 g herb or 320 mg lipophilic extract (standardized prepara-</p><p>tions made with supercritical carbon dioxide or hexane extraction tech-</p><p>niques). (Supercritical carbon dioxide extracts are made with carbon diox-</p><p>ide at a temperature and pressure at which it is in a state between liquid</p><p>and gas [the “supercritical state”], which preserves delicate fatty acids, and</p><p>leaves no residues in the finished product as with hexane-extracted fruits.)</p><p>Supercritical extracts are preferred in North America.</p><p>➤ Adverse effects: There are no known health hazards or side effects in conjunc-</p><p>tion with proper administration of the designated therapeutic doses of the</p><p>herb.

The herb consists of the branch tips and</p><p>young shoots of Thuja occidentalis (Thujae occidentalis stipites).</p><p>– Important constituents: Polysaccharides (immunostimulants), glycopro-</p><p>teins (immunostimulants), essential oil (1.4–4 %), (−)-thujone (α-thujone,</p><p>49–59 %), (+)-isothujone (β-thujone, 7–10 %), fenchone (10–15 %), flavo-</p><p>noids (quercetin, mearusitrin and the biflavonoids hinokiflavone, amento-</p><p>flavone, and bilobetin), proanthocyanidins, lignans, and tannins.</p><p>– Pharmacological properties: The antiviral effect of thujone has been demon-</p><p>strated in various trials. Topical application of the herb is therefore recom-</p><p>mended for viral warts. The polysaccharides in the herb promote T cell pro-</p><p>liferation (especially of CD4+ T-helper and inducer cells) and increase the</p><p>production of interleukin-2. The essential oil is spasmogenic and, when ad-</p><p>ministered in high doses, can induce clonic-tonic convulsions, damage to</p><p>the renal parenchyma, and cause severe metabolic disorders due to fatty</p><p>degeneration of the liver. Various Thuja species were among the most fre-</p><p>quently used medicinal agents, both externally and internally, for treating</p><p>infections, in native American medicine and in other cultures.</p><p>➤ Indications</p><p>– Colds and fever</p><p>– Decreased resistance to infections</p><p>– Psoriasis</p><p>– Warts</p><p>➤ Contraindications: None known.</p><p>➤ Dosage and duration of use</p><p>– Extract: 1–2 mL, 3 times a day.</p><p>– Tincture (undiluted): No more than 0.5 g, to be painted onto the affected site.</p><p>➤ Adverse effects: Arbor vitae is toxic. Symptoms of poisoning, especially after</p><p>abuse of the herb as an abortifacient, include nausea, vomiting, painful di-</p><p>arrhea, and mucosal bleeding. Fatalities have been reported.</p><p>Warning</p><p>– Poisoning: All cases of poisoning reported since 1980 were attributable to</p><p>consumption of the leaves and young shoots of the fresh thuja plant. The</p><p>toxic effect of the herb is attributable to its high content of thujone. The tox-</p><p>ic threshold for safe oral administration of thujone is reported to be</p><p>1.25 mg/kg body weight. When herbal remedies are administered at the</p><p>designated therapeutic doses, the thujone concentration remains far below</p><p>the toxic threshold. A tea is the safest form of administration because thu-</p><p>jone is not easily soluble in water.</p><p>➤ Herb–drug interactions: None known.</p><p>➤ Summary assessment: Use of thuja should be restricted to commercial prep-</p><p>arations and tea infusions.</p><p>➤ Literature</p><p>– Monographs: BHP 83; EB 6, Mar 31</p><p>– Scientific publications: see p. 478; Anon: Behandlung mit pflanzlichen</p><p>Immunmodulatoren.

Br.)</p><p>➤ General comments: The native inhabitants of South Africa have long used the</p><p>root of the uzara plant to treat digestive complaints. In Europe, it was first in-</p><p>troduced as an antidiarrheal herb in the early 1900s, and is also commonly</p><p>recommended for digestive cramps and irritable bowel syndromes today</p><p>because of its spasmolytic effect. To date, this herb has not found common</p><p>usage in North America.</p><p>➤ Pharmacology</p><p>– Herb: Uzara root (Uzarae radix). The herb consists of the dried, subterrane-</p><p>an parts of two- to three-year-old Xysmalobium undulatum (L.) R. B. plants</p><p>and preparations of the same.</p><p>– Important constituents: Steroid glycosides (cardenolides, their mixture is</p><p>also called uzarone or xysmalobin), uzarin (5.5 %), xysmalorin (1.5 %), and</p><p>pregnane derivatives.</p><p>– Pharmacological properties: Cardenolide glycosides (uzarin and xysma-</p><p>lorin) inhibit motility in the small intestine and urogenital tract. Because of</p><p>its glycoside content, higher doses of the herb have digitalis-like effects on</p><p>the heart. Clinical studies are not available.</p><p>➤ Indications: Acute, unspecific diarrhea.</p><p>➤ Contraindications: Use of cardiac glycosides, such as digoxin.</p><p>➤ Dosage and duration of use</p><p>– Daily dose: 45–90 mg total glycosides, calculated as uzarin.</p><p>– Use of uzara root should be limited to industrially produced tablets or tinc-</p><p>tures (to date only available in Europe), to be taken as instructed by the</p><p>manufacturer.</p><p>➤ Adverse effects: There are no known health hazards or side effects in conjunc-</p><p>tion with proper administration of the designated therapeutic doses of the</p><p>herb. Poisoning is unlikely when the herb is taken by the oral route because the</p><p>glycosides in the herb are poorly absorbed and their cardiac action is very</p><p>weak.</p><p>➤ Herb–drug interactions: Digitalis preparations and other cardiac glycosides.</p><p>➤ Summary assessment: Uzara is an effective herbal antidiarrheal agent, even</p><p>in cases of diarrhea with vomiting. Because of its excellent tolerability, it can</p><p>be safely administered to infants and young children.</p><p>✿ Literature</p><p>– Monographs: Commission E</p><p>– Scientific publications: see p. 478; Schmidt M: Uzarawurzel.

The drug consists of</p><p>the rhizomes, roots, and stolons of the plant and preparations of the same.</p><p>➤ Pharmacology</p><p>– Drug: Valerian root (Valerianae radix).</p><p>– Important constituents: Iridoids (valepotriate, 0.5–2.0 %); essential oil, 0.2–</p><p>1.0 % (bornyl-isovalerianate, isovalerianic acid; sometimes also valerenal</p><p>and valeranone), and sesquiterpenes (valerenic acid, 0.1–0.9 %).</p><p>– Pharmacological properties: Valerian has central depressant, sedative, anxio-</p><p>lytic, spasmolytic, and muscle relaxant effects in animals and has a benzo-</p><p>diazepine-like effect on the GABA system. Valepotriates have a sedative effect</p><p>on the autonomic nervous system. The essential oil has sedative and spasmo-</p><p>lytic effects on the central nervous system. The efficacy of valerian prepara-</p><p>tions depends largely on the quality and freshness of the starting material, the</p><p>extraction process, and the freshness of the extract. In humans it reduces the</p><p>sleep induction time and has sedative action during the daytime.</p><p>Warning: Although Valerian tea and tincture do not contain any valepotri-</p><p>ates (because they are unstable), they do contain degradation products</p><p>with similar action. The long-term safety of these products has not been</p><p>determined.</p><p>➤ Indications</p><p>– Difficulty in falling asleep due to nervous tension</p><p>– Restlessness, anxiety, nervous agitation</p><p>– Lack of concentration, decreased mental performance</p><p>➤ Contraindications: None known.</p><p>➤ Dosage and duration of use: Used internally and externally (hydrotherapy).</p><p>– Tea: Steep 1 teaspoonful (3–5 g) of the chopped roots and rhizomes in</p><p>150 mL of hot water for 10 to 15 minutes.</p><p>• Dosage: 2 to 3 cups a day, plus 1 cup before retiring.</p><p>• Daily dose: 15 g herb.</p><p>– 1 : 5 tincture: 15–20 drops several times a day.</p><p>– Extract: 2–3 g herb, one to several times a day.</p><p>➤ Adverse effects: No known health hazards. Gastrointestinal symptoms are</p><p>rare side effects and contact allergies are very</p><p>rare. Headaches, anxiety, insom-</p><p>nia, mydriasis and disturbance of heart action occasionally occur during pro-</p><p>longed use of high doses.</p><p>➤ Herb–drug interactions: None known</p><p>Warning: Valepotriate-free preparations are currently recommended for</p><p>pediatric use since the potential risk of mutagenic and/or genotoxic effects has</p><p>not yet been satisfactorily defined.</p><p>➤ Summary assessment: Valerian tea, tincture, and other valepotriate-free prepa-</p><p>rations promote the induction of sleep. Preparations containing valepotriates</p><p>are effective in the treatment of daytime mental and motor agitation and lack</p><p>of concentration; they have a calming effect when taken prior to stress situa-</p><p>tions. The ability to drive a motor vehicle or operate machinery is not impaired.</p><p>✿ Literature</p><p>– Monographs: DAB 1998; ESCOP; Commission E</p><p>Plant Summaries—V</p><p>12</p><p>6</p><p>M</p><p>ed</p><p>ic</p><p>in</p><p>al</p><p>P</p><p>la</p><p>n</p><p>ts</p><p>fr</p><p>o</p><p>m</p><p>A</p><p>t</p><p>o</p><p>Z</p><p>2</p><p>1</p><p>2</p><p>3</p><p>4</p><p>5</p><p>6</p><p>7</p><p>8</p><p>9</p><p>10</p><p>11</p><p>12</p><p>13</p><p>14</p><p>15</p><p>16</p><p>17</p><p>18</p><p>19</p><p>20</p><p>21</p><p>22</p><p>23</p><p>24</p><p>25</p><p>26</p><p>27</p><p>28</p><p>29</p><p>30</p><p>31</p><p>32</p><p>33</p><p>34</p><p>35</p><p>36</p><p>37</p><p>38</p><p>39</p><p>40</p><p>41</p><p>42</p><p>43</p><p>44</p><p>45</p><p>46</p><p>47</p><p>48</p><p>49</p><p>50</p><p>– Scientific publications: see p. 478; Amon: Phytotherapeutika: Nachge-</p><p>wiesene Wirkung, aber wirksame Stoffe meist nicht bekannt.

It is now used to relieve gastrointestinal complaints. There are numerous</p><p>subspecies of yarrow such as Achillea asiatica which is used medicinally in Asia.</p><p>➤ Pharmacology</p><p>– Herb: Yarrow herb (Millefolii herba). The herb consists of the fresh or dried</p><p>aerial parts of Achillea millefolium L., collected at the time of flowering, and</p><p>preparations of the same.</p><p>– Important constituents: Essential oil (0.2–1.0 %) containing chamazulene</p><p>(6–40 % max.), camphor (20 %), β-pinene (23 %), and 1,8-cineole (up to</p><p>10 %). Sesquiterpene lactones (mainly guaianolides) and flavonoids (api-</p><p>genin-7-O-glucoside and rutin) are also present. Azulenes tend to occur in</p><p>the tetraploid subspecies growing in meadows, rather than hexaploid sub-</p><p>species growing in forests.</p><p>– Pharmacological properties: The bitter principles (guaianolides) have chol-</p><p>agogic effects, whereas the flavonoids are spasmolytic. The interaction of</p><p>different compounds (chamazulene and flavonoids) renders the herb anti-</p><p>edematous, anti-inflammatory, and antibacterial.</p><p>– Achillea asiatica: Has antiulcerogenic activity in rats, and anti-inflammatory</p><p>effects; contains high levels of chamazulene. Only a few varieties of A. mille-</p><p>folium contain chamazulenes. The German Pharmacopeia specifies that</p><p>yarrow flowers for tea should contain not less than 0.2 %, the Austrian and</p><p>French Pharmacopeias specify at least 0.3 % essential oil, with 0.02 %</p><p>proazulenes, calculated as chamazulene.</p><p>➤ Indications</p><p>– Internal use: Lack of appetite, dyspeptic complaints, liver and gallbladder</p><p>complaints.</p><p>– External use: For treatment of spasmodic pain in the minor pelvis.</p><p>➤ Contraindications: Allergy to yarrow or other composite plants.</p><p>➤ Dosage and duration of use</p><p>– Tea: Pour boiling water onto 2–5 g of the finely chopped herb, cover and</p><p>steep for 10 to 15 minutes.</p><p>• Dosage: One cup, between meals, 3 to 4 times a day.</p><p>– External use: Steep 100 g yarrow herb in 1 to 2 liters of water for 20 minutes,</p><p>then add to bathwater.</p><p>➤ Adverse effects: There are no known health hazards or side effects in conjunc-</p><p>tion with proper administration of the designated therapeutic doses of the</p><p>herb. The herb has a weak to moderate potential for sensitization.</p><p>➤ Herb–drug interactions: None known.</p><p>➤ Summary assessment: Yarrow is a well-known and well-tolerated herbal rem-</p><p>edy. Some species, including most varieties of A. millefolium, have little or no</p><p>chamazulenes, reducing their anti-inflammatory effects. Products from cultivat-</p><p>ed varieties in Europe, but not North America are required to contain not less</p><p>than 0.2 % proazulenes.</p><p>✿ Literature</p><p>– Monographs: DAB 1998; Commission E</p><p>– Scientific publications: see p. 478; Kastner U, Glasl S, Jurenitsch J: Achillea</p><p>millefolium – ein Gallentherapeutikum.

The main causes are hypertension (see p. 138) with in-</p><p>creased venous pressures or cardiac volumes, valvular defects, and</p><p>ischemia due to sclerotic coronary artery disease (see p. 134).</p><p>– The body attempts to compensate for the circulatory deficiency by stimu-</p><p>lating mechanisms such as the sympathetic nervous system and by narrow-</p><p>ing the blood vessels, resulting in a higher workload on the heart. Addition-</p><p>al compensatory mechanisms lead to a further decrease in cardiac</p><p>performance.</p><p>– Effective treatment measures should be initiated as early as possible to pre-</p><p>vent the progression of heart failure.</p><p>➤</p><p>Prognosis:</p><p>The overall prognosis for heart failure remains poor although the</p><p>conventional treatments (diuretics, ACE inhibitors, beta blockers, AT</p><p>1</p><p>-block-</p><p>ers, digitalis) are effective.</p><p>➤</p><p>Classification:</p><p>According to the system of the New York Heart Association</p><p>(NYHA), heart failure is divided into four clinical stages:</p><p>– NYHA I: Symptoms do not occur during normal physical exercise.</p><p>– NYHA II: Symptoms occur during more strenuous exercise.</p><p>– NYHA III: Symptoms occur during light exercise.</p><p>– NYHA IV: Symptoms occur even at rest.</p><p>➤</p><p>Clinical value of herbal medicine:</p><p>Hawthorn and digitaloid herbs are used in</p><p>NYHA I and II heart failure. The current knowledge does not support treatment</p><p>of NYHA III and IV heart failure by herbal remedies.</p><p>Recommended Herbal Remedies</p><p>Flavonoid-containing Herbs</p><p>➤</p><p>Hawthorn leaf and flower</p><p>(Crataegie folium cum flore; see p. 74).</p><p>–</p><p>Action</p><p>: Procyanidins enhance the influx of calcium into cardiac muscle</p><p>fibers while only moderately increasing the oxygen demand. These com-</p><p>pounds widen the coronary arteries and other cardiac vessels,</p><p>thereby ex-</p><p>tending the refractory time. This results in an antiarrhythmic effect.</p><p>– Advantages of hawthorn</p><p>•</p><p>Effective and well-tolerated in the early stages of heart failure, especially</p><p>in patients with age-related degenerative changes in the heart muscle.</p><p>•</p><p>With a high rate of acceptance by patients, hawthorn leaf and flower</p><p>have only few side effects.</p><p>•</p><p>Since flavonoids do not reduce the afterload, hawthorn can also be used</p><p>by patients with low blood pressure.</p><p>•</p><p>Hawthorn can be recommended for long-term use, and it combines well</p><p>with cardiac glycosides, but may have a synergistic effect. This potential</p><p>interaction should be watched. It may allow a reduction in medications</p><p>like digoxin while maintaining the same overall therapeutic effect.</p><p>–</p><p>Dosage and administration</p><p>: One oral dose, 2 to 3 times daily. Relatively large</p><p>doses over time are needed for sufficient effects. A daily dose of ca. 900 mg</p><p>hawthorn total extract is generally recommended. The herbal remedy takes</p><p>around 4 weeks to become fully effective.</p><p>4.1 Heart Failure</p><p>13</p><p>3</p><p>Ca</p><p>rd</p><p>io</p><p>va</p><p>sc</p><p>u</p><p>la</p><p>r</p><p>D</p><p>is</p><p>ea</p><p>se</p><p>s</p><p>3</p><p>1</p><p>2</p><p>3</p><p>4</p><p>5</p><p>6</p><p>7</p><p>8</p><p>9</p><p>10</p><p>11</p><p>12</p><p>13</p><p>14</p><p>15</p><p>16</p><p>17</p><p>18</p><p>19</p><p>20</p><p>21</p><p>22</p><p>23</p><p>24</p><p>25</p><p>26</p><p>27</p><p>28</p><p>29</p><p>30</p><p>31</p><p>32</p><p>33</p><p>34</p><p>35</p><p>36</p><p>37</p><p>38</p><p>39</p><p>40</p><p>41</p><p>42</p><p>43</p><p>44</p><p>45</p><p>46</p><p>47</p><p>48</p><p>49</p><p>50</p><p>Note:</p><p>Tea infusion is not the best way to extract water-soluble com-</p><p>pounds from hawthorn. Hawthorn tea therefore has only weak effects</p><p>and can be recommended, at best, only for a health-promoting effect in</p><p>the very early stages of cardiac insufficiency, or as a long-term prevent-</p><p>ative measure.</p><p>Digitaloid Herbs</p><p>➤</p><p>Adonis</p><p>(Adonidis herba; see p. 33),</p><p>lily-of-the-valley</p><p>(Convallariae herba; see</p><p>p. 86), and</p><p>squill root</p><p>(Scillae bulbus; see p. 110).</p><p>–</p><p>Action</p><p>: The effects are comparable to those of the isolated substances dig-</p><p>oxin and digitoxin, but the herbal preparations have secondary effects such</p><p>as increased urinary excretion (squill) or frequency (lily-of-the-valley).</p><p>–</p><p>Advantages</p><p>: The herbal preparations have a somewhat wider therapeutic</p><p>range than the isolated substances, but their concentrations can extend into</p><p>the toxic range.</p><p>–</p><p>Disadvantages</p><p>: The absorption of the active compounds in the herbal prep-</p><p>arations is generally poor and variable. Hence, their bioavailabilities and</p><p>potencies are usually low.</p><p>–</p><p>Dosage and administration</p><p>: One oral dose, 2 to 3 times daily. Individualized</p><p>dose setting is required.</p><p>Warning:</p><p>All digitaloid preparations can be toxic (similar to the glycosides</p><p>digoxin and digitoxin), producing symptoms such as nausea, vomiting,</p><p>stomach complaints, diarrhea, and cardiac arrhythmias.</p><p>Combinations of Flavonoid and Digitaloid Herbs</p><p>–</p><p>Advantages</p><p>:</p><p>The tolerance is said to be better than that of preparations con-</p><p>taining digitaloid herbs alone.</p><p>–</p><p>Disadvantages</p><p>:</p><p>Their therapeutic range is smaller than that of pure haw-</p><p>thorn preparations, and their toxic effects are similar to those of digitaloid</p><p>drugs.</p><p>4.1 Heart Failure</p><p>13</p><p>4</p><p>Ca</p><p>rd</p><p>io</p><p>va</p><p>sc</p><p>u</p><p>la</p><p>r</p><p>D</p><p>is</p><p>ea</p><p>se</p><p>s</p><p>3</p><p>1</p><p>2</p><p>3</p><p>4</p><p>5</p><p>6</p><p>7</p><p>8</p><p>9</p><p>10</p><p>11</p><p>12</p><p>13</p><p>14</p><p>15</p><p>16</p><p>17</p><p>18</p><p>19</p><p>20</p><p>21</p><p>22</p><p>23</p><p>24</p><p>25</p><p>26</p><p>27</p><p>28</p><p>29</p><p>30</p><p>31</p><p>32</p><p>33</p><p>34</p><p>35</p><p>36</p><p>37</p><p>38</p><p>39</p><p>40</p><p>41</p><p>42</p><p>43</p><p>44</p><p>45</p><p>46</p><p>47</p><p>48</p><p>49</p><p>50</p><p>Clinical Considerations</p><p>➤</p><p>General comments</p><p>– The prevalence of coronary artery disease (CAD) is increasing in industrial-</p><p>ized countries. This is certainly attributable to a general lack of physical</p><p>exercise, increased consumption of fatty foods, and cigarette smoking, but</p><p>is also due to the fact that people now live longer.</p><p>– Despite intensive research, some risk factors of CAD are still unknown or</p><p>untreatable.</p><p>➤</p><p>Herbal treatment measures</p><p>– In Germany, topical heart ointments containing aromatic herbs that in-</p><p>crease local blood flow of cutivisceral reflex regions are thought to be ben-</p><p>eficial in acute functional coronary artery spasms.</p><p>– Flavonoids in hawthorn extract reduce wall tension in normal and sclerotic</p><p>blood vessels. These chemicals are also presumed to stimulate beta-2 re-</p><p>ceptors and, thus, to widen coronary arteries and blood vessels in skeletal</p><p>muscle. The usefulness of hawthorn in CAD is therefore arguable, but has</p><p>not yet been confirmed in clinical studies.</p><p>➤</p><p>Clinical value of herbal medicine</p><p>– The recommendations in this section are solely based on empirical experi-</p><p>ence. Clinical study data or controlled studies on most of these indications</p><p>are not yet available.</p><p>– Once CAD has become manifest, herbal measures should be restricted to</p><p>adjunctive treatment only.</p><p>➤</p><p>Herbal measures to help counteract risk factors</p><p>– Antilipemic herbs: Garlic (see p. 70), artichoke (see p. 36).</p><p>– Antithrombotic herbs: Garlic (see p. 70).</p><p>– Antihypertensive herbs: Garlic (see p. 70).</p><p>➤</p><p>Clinical value of herbal medicine for risk factors of CAD</p><p>– The herbal treatments outlined here are purely prophylactic and adjunctive</p><p>measures that can be recommended as home remedies.

The</p><p>typical patient complains of heart palpitations.</p><p>– The most common symptoms are “loud” heartbeat, cardiac arrhythmias,</p><p>subjective feeling of unrest, diffuse left precordial, non-load-dependent</p><p>pressure sensation, sudden shortness of breath, nervousness, anxiety, rapid</p><p>fatigability, insomnia, lack of concentration, tendency to sweat heavily,</p><p>symptoms of heart “agitation.”</p><p>– The cardiac work-up usually does not reveal any abnormalities. If any</p><p>changes are found, they are usually harmless extrasystoles or functional</p><p>coronary spasms.</p><p>➤ Clinical value of herbal medicine: Herbal preparations can be helpful because</p><p>no specific synthetic drugs or chemical remedies for functional heart disorders</p><p>exist.

Nonetheless, they may have a positive or negative effect</p><p>on the efficacy of the active principles in drugs.</p><p>➤ Products of secondary metabolism: Many secondary plant substances pro-</p><p>tect plants from feeding damage, act as storage or waste products, or ward off</p><p>pests and diseases. Some are pharmacologically active.</p><p>Examples of Products of Primary Metabolism</p><p>➤ Pectins</p><p>– Substance group: Carbohydrates.</p><p>– Example: Apple pectin.</p><p>– Structural properties: High-molecular weight compounds comprising</p><p>sugarlike molecules.</p><p>– Plant sources: Found in many kinds of fruit, especially when unripe.</p><p>– Pharmacological properties: Pectins cannot be digested by endogenous in-</p><p>testinal juices and have a high water-binding capacity.</p><p>– Indications: Diarrhea.</p><p>• Pectins lower the pH of the bowel because they encourage growth of</p><p>beneficial bacteria.

The contents should be discard-</p><p>ed after the expiration date specified on the label.</p><p>– Medicinal action: Usually relatively weak, except in rare cases (expressed</p><p>Echinacea juice, for example).</p><p>➤ Distillates</p><p>– Definition: Formulations obtained by extracting active principles from fresh</p><p>or dried plant material by steam distillation.</p><p>– Preparation: Obtained by separating the steam-volatile constituents of</p><p>fresh or dried medicinal plants by vaporization.</p><p>– Storage: See p. 5.</p><p>– Medicinal action: Determined by the water-volatile constituents (e. g., mus-</p><p>tard oils, essential oils) contained in the distillate.</p><p>1.4 Herbal Formulations</p><p>12</p><p>Fu</p><p>n</p><p>d</p><p>am</p><p>en</p><p>ta</p><p>ls</p><p>o</p><p>f P</p><p>h</p><p>yt</p><p>o</p><p>th</p><p>er</p><p>ap</p><p>y</p><p>1</p><p>1</p><p>2</p><p>3</p><p>4</p><p>5</p><p>6</p><p>7</p><p>8</p><p>9</p><p>10</p><p>11</p><p>12</p><p>13</p><p>14</p><p>15</p><p>16</p><p>17</p><p>18</p><p>19</p><p>20</p><p>21</p><p>22</p><p>23</p><p>24</p><p>25</p><p>26</p><p>27</p><p>28</p><p>29</p><p>30</p><p>31</p><p>32</p><p>33</p><p>34</p><p>35</p><p>36</p><p>37</p><p>38</p><p>39</p><p>40</p><p>41</p><p>42</p><p>43</p><p>44</p><p>45</p><p>46</p><p>47</p><p>48</p><p>49</p><p>50</p><p>➤ Oily extracts</p><p>– Definition: The preparation obtained by dissolving the fat-soluble constitu-</p><p>ents of a medicinal plant in, for example, olive oil, almond oil, or peanut oil.</p><p>– Preparation: Prepared by immersing the freshly cut or dried plant parts in</p><p>a vegetable oil and allowing them to stand, usually at room temperature,</p><p>until the fat-soluble constituents have been extracted.</p><p>– Storage: These preparations are relatively unstable and should therefore be</p><p>prepared in small quantities (see p. 5 for storage instructions).</p><p>Extracts</p><p>➤ Definition</p><p>– Extracts are prepared by dissolving medicinal plants in a solvent to separate</p><p>their active principles from extraneous substances.</p><p>– The type of formulation (aqueous, alcoholic) depends on the type of solvent</p><p>used (water, alcohol).</p><p>– Extracts are characterized as either dry or liquid depending on the concen-</p><p>tration of residual solvent in the final product.</p><p>Note: The composition of and uses for preparations from the same plant may</p><p>differ between the various preparation techniques. Hence, any extract pro-</p><p>duced by a special preparation technique is a unique active substance.</p><p>➤ Process of manufacturing plant extracts: See Fig. 1.</p><p>➤ Aqueous extract</p><p>– Definition: An extract prepared using water as the extracting agent. These</p><p>extracts mainly contain water-soluble constituents and few lipid-soluble</p><p>components.</p><p>– Disadvantages: The individual constituents are relatively unstable, and</p><p>microorganisms can multiply rapidly.</p><p>➤ Alcohol extract</p><p>– Definition: An extract prepared using ethanol and water mixed at various</p><p>ratios and concentrations, called the menstruum.</p><p>– Preparation</p><p>• In Germany the standard procedure calls for the plant material to be cut</p><p>into pieces and then steeped in the menstruum (macerated) for several</p><p>hours; in the North American standard the fresh or dried and powdered</p><p>plant material is macerated in the menstruum for a week to 10 days and</p><p>the liquid is then pressed out with a hydraulic press (if available).</p><p>• The drug is repeatedly steeped in the menstruum, strained and concen-</p><p>trated (percolation) until completely extracted.</p><p>– Advantages</p><p>• Ethanol (grain alcohol) is an excellent extracting agent. At higher vol-</p><p>ume concentrations, it can also extract lipophilic drug constituents, such</p><p>as essential oils.</p><p>• Alcohol preserves the extracts for a longer times (up to 2 to 3 years).</p><p>• Alcohol assists rapid absorption of the active ingredients.</p><p>➤ Tincture</p><p>– Definition: A solution prepared by macerating or percolating a medicinal</p><p>herb in various concentrations of ethanol.</p><p>• According to the German Pharmacopeia (DAB 1996), dry extracts made</p><p>by using suitable concentrations of ethanol are also defined as tinctures.</p><p>1.4 Herbal Formulations</p><p>13</p><p>Fu</p><p>n</p><p>d</p><p>am</p><p>en</p><p>ta</p><p>ls</p><p>o</p><p>f P</p><p>h</p><p>yt</p><p>o</p><p>th</p><p>er</p><p>ap</p><p>y</p><p>1</p><p>1</p><p>2</p><p>3</p><p>4</p><p>5</p><p>6</p><p>7</p><p>8</p><p>9</p><p>10</p><p>11</p><p>12</p><p>13</p><p>14</p><p>15</p><p>16</p><p>17</p><p>18</p><p>19</p><p>20</p><p>21</p><p>22</p><p>23</p><p>24</p><p>25</p><p>26</p><p>27</p><p>28</p><p>29</p><p>30</p><p>31</p><p>32</p><p>33</p><p>34</p><p>35</p><p>36</p><p>37</p><p>38</p><p>39</p><p>40</p><p>41</p><p>42</p><p>43</p><p>44</p><p>45</p><p>46</p><p>47</p><p>48</p><p>49</p><p>50</p><p>H</p><p>er</p><p>b</p><p>Tr</p><p>an</p><p>sf</p><p>o</p><p>rm</p><p>in</p><p>g</p><p>F</p><p>re</p><p>sh</p><p>ly</p><p>H</p><p>ar</p><p>ve</p><p>st</p><p>ed</p><p>P</p><p>la</p><p>n</p><p>ts</p><p>in</p><p>to</p><p>E</p><p>xt</p><p>ra</p><p>ct</p><p>s</p><p>El</p><p>ua</p><p>te</p><p>D</p><p>ry</p><p>e</p><p>xt</p><p>ra</p><p>ct</p><p>,</p><p>na</p><p>ti</p><p>ve</p><p>N</p><p>at</p><p>iv</p><p>e</p><p>dr</p><p>y</p><p>ex</p><p>tr</p><p>ac</p><p>tC</p><p>ut</p><p>G</p><p>ro</p><p>un</p><p>d</p><p>+S</p><p>O</p><p>L:</p><p>fa</p><p>tt</p><p>y</p><p>oi</p><p>l</p><p>+S</p><p>O</p><p>L:</p><p>e</p><p>th</p><p>an</p><p>ol</p><p>+</p><p>w</p><p>at</p><p>er</p><p>Ev</p><p>ap</p><p>or</p><p>at</p><p>ed</p><p>+E</p><p>th</p><p>an</p><p>ol</p><p>D</p><p>rie</p><p>d</p><p>+E</p><p>th</p><p>an</p><p>ol</p><p>G</p><p>ro</p><p>un</p><p>d</p><p>an</p><p>d</p><p>si</p><p>ft</p><p>ed</p><p>Te</p><p>a</p><p>m</p><p>at</p><p>er</p><p>ia</p><p>l</p><p>H</p><p>er</p><p>b</p><p>po</p><p>w</p><p>de</p><p>r</p><p>Ex</p><p>pr</p><p>es</p><p>se</p><p>d</p><p>ju</p><p>ic</p><p>e</p><p>O</p><p>ily</p><p>m</p><p>ac</p><p>er</p><p>at</p><p>io</p><p>n</p><p>O</p><p>ily</p><p>m</p><p>ac</p><p>er</p><p>at</p><p>io</p><p>n</p><p>D</p><p>ry</p><p>e</p><p>xt</p><p>ra</p><p>ct</p><p>Fl</p><p>ui</p><p>d</p><p>ex</p><p>tr</p><p>ac</p><p>t/</p><p>ti</p><p>nc</p><p>tu</p><p>re</p><p>SO</p><p>L:</p><p>s</p><p>ol</p><p>ve</p><p>nt</p><p>G</p><p>re</p><p>en</p><p>li</p><p>ne</p><p>: h</p><p>er</p><p>b</p><p>pr</p><p>ep</p><p>ar</p><p>at</p><p>io</p><p>n</p><p>(n</p><p>at</p><p>iv</p><p>e)</p><p>G</p><p>ra</p><p>y</p><p>lin</p><p>e:</p><p>e</p><p>xt</p><p>ra</p><p>ct</p><p>p</p><p>re</p><p>pa</p><p>ra</p><p>ti</p><p>on</p><p>Fr</p><p>es</p><p>h</p><p>pl</p><p>an</p><p>ts</p><p>D</p><p>rie</p><p>d</p><p>C</p><p>ut</p><p>he</p><p>rb</p><p>Fig. 1 The process of manufacturing plant extracts.</p><p>1.4 Herbal Formulations</p><p>14</p><p>Fu</p><p>n</p><p>d</p><p>am</p><p>en</p><p>ta</p><p>ls</p><p>o</p><p>f P</p><p>h</p><p>yt</p><p>o</p><p>th</p><p>er</p><p>ap</p><p>y</p><p>1</p><p>1</p><p>2</p><p>3</p><p>4</p><p>5</p><p>6</p><p>7</p><p>8</p><p>9</p><p>10</p><p>11</p><p>12</p><p>13</p><p>14</p><p>15</p><p>16</p><p>17</p><p>18</p><p>19</p><p>20</p><p>21</p><p>22</p><p>23</p><p>24</p><p>25</p><p>26</p><p>27</p><p>28</p><p>29</p><p>30</p><p>31</p><p>32</p><p>33</p><p>34</p><p>35</p><p>36</p><p>37</p><p>38</p><p>39</p><p>40</p><p>41</p><p>42</p><p>43</p><p>44</p><p>45</p><p>46</p><p>47</p><p>48</p><p>49</p><p>50</p><p>– Preparation: Tinctures are prepared using 1 part drug and 5 parts extractant</p><p>or, with high-potency constituents like atropine from belladonna, 1 part</p><p>drug and 10 parts extractant.</p><p>– Labeling: Dried herb to extract ratio (HER) = 1 : 5 or 1 : 10 means that the</p><p>preparation was prepared using 1 part plant material and 5 or 10 parts of</p><p>the menstruum.</p><p>– Storage (see p. 5): Should not be stored for more than one year owing to the</p><p>potential instability of certain compounds in the extract. Some studies by</p><p>Bauer, a leading authority on echinacea, and co-workers show the stability</p><p>of echinacea tincture under normal conditions to be 2 to 3 years with about</p><p>30 % reduction in some important constituents per year. (Personal commu-</p><p>nication, Rudi Bauer, PhD, 1987.)</p><p>Note: Many tinctures should not be used undiluted.</p><p>➤ Fluid extract (fluid extract)</p><p>– Definition: An alcoholic preparation of a medicinal herb containing higher</p><p>concentrations of plant constituents than are found in conventional tinc-</p><p>tures. One part of fluid extract generally corresponds to one part of the par-</p><p>ent herb calculated on a dry-weight basis. This concentration has to be</p><p>achieved by evaporating off some of the alcohol.</p><p>– Preparation: As for tinctures.</p><p>➤ Dry extracts (powdered extracts)</p><p>– Definition: Solid preparations obtained by condensing and drying fluid ex-</p><p>tracts. A powdered extract contains generally 95 % solids and 5 % water resi-</p><p>due (moisture). A native extract or native dry extract contains only plant</p><p>extract material and is free of additives.</p><p>– Preparation</p><p>• Fluid extracts are separated from solvents by carefully heating the ex-</p><p>tract and allowing the solvent to evaporate, often in a vacuum chamber</p><p>by freeze-drying or spray-drying.</p><p>• The selected drying method has a decisive effect on product quality; for</p><p>example, excessive heat degrades some active constituents.</p><p>• Adjuvants and carriers such as highly dispersed silica, lactose, and me-</p><p>thylcellulose are sometimes added to prevent caking and to adjust the</p><p>final extract concentration. Extracts that are adjusted to 5 : 1 (meaning</p><p>that 1 part of the finished extract is equivalent to all the desirable and</p><p>active constituents of 5 parts of the dried herb) are typical.</p><p>• The package labeling provides information on the parent plant or plant</p><p>part, the extractant, and the dried herb/extract ratio (HER). An HER of</p><p>10 : 1 means that 10 parts of the plant material yielded 1 part extract. A</p><p>low HER (such as 1 : 2) indicates a high concentration of the active com-</p><p>pounds in the plant material.</p><p>➤ Special extracts</p><p>– Definition: Extracts that undergo special extraction and purification pro-</p><p>cesses to separate, concentrate, and free them from toxic and undesirable</p><p>substances.</p><p>– Preparation</p><p>• Special extracts are made from raw extracts.</p><p>• The raw extract undergoes special extraction and purification processes</p><p>to increase the concentration of desirable active principles.</p><p>1.4 Herbal Formulations</p><p>15</p><p>Fu</p><p>n</p><p>d</p><p>am</p><p>en</p><p>ta</p><p>ls</p><p>o</p><p>f P</p><p>h</p><p>yt</p><p>o</p><p>th</p><p>er</p><p>ap</p><p>y</p><p>1</p><p>1</p><p>2</p><p>3</p><p>4</p><p>5</p><p>6</p><p>7</p><p>8</p><p>9</p><p>10</p><p>11</p><p>12</p><p>13</p><p>14</p><p>15</p><p>16</p><p>17</p><p>18</p><p>19</p><p>20</p><p>21</p><p>22</p><p>23</p><p>24</p><p>25</p><p>26</p><p>27</p><p>28</p><p>29</p><p>30</p><p>31</p><p>32</p><p>33</p><p>34</p><p>35</p><p>36</p><p>37</p><p>38</p><p>39</p><p>40</p><p>41</p><p>42</p><p>43</p><p>44</p><p>45</p><p>46</p><p>47</p><p>48</p><p>49</p><p>50</p><p>• Toxins and undesirable substances that do not contribute to the medi-</p><p>cinal action of the preparation are removed.</p><p>• This treatment reduces the risk factors associated with the native mate-</p><p>rial, and often provides a finished product that is many times more con-</p><p>centrated in one or more active constituents than is the parent herb,</p><p>such as the highly concentrated and standardized ginkgo extract typi-</p><p>cally sold in consumer products (50 : 1). Hence, the effects of the special</p><p>extract can no longer be compared with those of the raw materials.</p><p>Medicinal Teas</p><p>➤ Definition: Herb teas, such as orthosiphon or lobelia, with a strong medicinal</p><p>action.
