Making Medicinal Plant Tinctures

Transcription

1 Making Medicinal Plant Tinctures Working with Medicinal Plants Medicinal plants have been used to heal for millennia. They are readily available, usually growing as "weeds" everywhere that humans live. Herbs can be used to safely and effectively heal a wide range of imbalances and disorders. They heal by stimulating the innate healing wisdom of the body. Because people and plants have evolved together or have grown in the same environment and have been subjected to the same stresses of life, using local herbs as medicine can be one of the most effective ways to cure disease. Herbs, respectfully harvested from the wild, are basically "free," and the techniques of processing them into medicine require little monetary input. One needs only a small room to dry the herbs that will be used for teas. In many cultures this is done in the family living space. For making tinctures, a supply of alcohol and glass jars are needed. Other tools that are helpful are strainers, cheesecloth, funnels, a scale, measuring cups, and a small herb press. Oil and beeswax are necessary for making topical preparations. Harvesting Guidelines Leaves harvest midmorning after dew has evaporated. Leaves are usually most potent just before plant flowers. Leaves of biennials best harvested in the summer of first year. If stems are succulent and have the taste of the plant you may want to include them with the leaves. Flowers harvest in early stages preferably just after opening and prior to pollination. Roots usually dug in the fall at the end of the growing season or when dormant. At this time they are full of the energy they have stored for the winter. Roots are generally more sweet and tonic when dug in the spring and have a gentler effect. Seeds Generally the best time to harvest is just as they have fully matured. The time of greatest potency can be ascertained by tasting seeds in various stages. Wildcrafting Ethic 1. Make positive identification before harvesting. 2. Know the rare and endangered plants of the area and don't pick them. 3. Make Assessments: Ecological Implications-Will your impact be noticeable? Will it adversely effect the often delicate ecological balance of the stand or the intricate web of interrelations that ensure its continued existence? Animal/Insect Interactions-Are there animals or insects that depend on this plant for food or other uses? How will your harvesting impact these relationships? Personal-Are you in the proper emotional state to make a harvest? Are you prepared to be honest with yourself in regards to making decisions about your impact on this stand? How much of this medicine can or will you realistically process and use?

2 4. Ask permission from and make offerings to the plant. Remember that when you treat plants with respect, they will not only be more effective as medicine, but they will be more likely to reveal themselves to you. 5. Pick from different stands or spots in a stand to minimize impact. 6. Care for and develop a relationship with the stand. Leave any area you harvest from in the same or better condition than you found it (e.g. fill in holes after harvesting roots, don't leave discarded leaves or other plant parts lying around where others can see them, and whenever possible replant root crowns or disperse seeds.) Observe the stand over time so that you can continue to refine your personal assessment of any harvesting impact you have had or any natural environmental changes that may have an effect on the health of the stand. Based on this information, be prepared to alter your wildcrafting practices or stop harvesting altogether from this spot. What are tinctures? A tincture is made by macerating (i.e. soaking) plant material in a solvent to extract its medicinal properties. Generally alcohol is used, but sometimes other solvents such as glycerin or vinegar are used. The solvent has both the effect of extracting the medicinal constituents from the plant material and acting as a preservative. Alcohol is not only the best solvent but it is a better preservative than either vinegar or glycerin. Why do we make plant medicines into tinctures? Because they are processed without the use of heat they generally represent the actual chemistry of the herb more closely than other preparations. If preserved with alcohol, they will (in most cases) remain stable for many years. They are a convenient way to take medicine. Dosages can be carefully measured. Tinctures are quickly and readily absorbed into the bloodstream. For this reason they are especially useful for acute cases. Menstruum Ratios, Alcohol Percentages, Etc. Standard Herb to Menstruum ratios are generally 1:2 for fresh herb or 1:5 for dried herb, which is the weight of herb to volume of menstruum. The menstruum is the solvent or liquid used to extract the medicinal constituents from the herb. You will usually see it written as a ratio of Alcohol to Water (e.g. 50A:50W, 50% grain alcohol to 50% distilled water.) Sometimes other ingredients such as Glycerin (to stabilize tannins) or Vinegar (to extract alkaloids or minerals) are added in which case it would look something like this: 50A:40W:10Gly. I prefer to use pure grain alcohol (190 proof) so that I can easily make the menstruum equal the ratio I need by adding distilled water. I use grams and liters because it is much easier to make calculations metrically. 2

3 22% alcohol is the minimum to preserve. Divide proof in half to get percentage (e.g. 80 proof Vodka is 40% alcohol.) Making Tinctures Folk Method 1. Finely chop fresh herb or grind dried herb to the consistency of corn meal with a coffee grinder (if you grind it too fine it will clump leading to a less consistent extraction.) Place in jar. 2. Add vodka or other alcohol to cover herb (must be at least 22% for dry herb or 40% for fresh herb to ensure preservation.) Label accordingly. 3. When making a dry herb preparation shake twice daily as it is necessary for herb to be in contact with menstruum so that full extraction is possible. Fresh herb constituents are extracted by alcohol breaking cell walls so shaking is not necessary. 4. After about 2 weeks, depending on the herb, filter out plant material. Press remaining liquid through cheesecloth. 5. Let settle overnight. Filter sediment through coffee filter. 6. Store in a cool, dark place. Fresh Herb Tincture 1:2 1. Place 1 part (by weight) chopped fresh herb in a glass jar. 2. Determine proper ratio of menstruum. Cover herb with 2 parts (by volume) of this menstruum. 3. Follow steps 3 to 6 of the Folk Method. Dry Herb Tincture 1:5 1. Place 1 part (by weight) ground dried herb in a glass jar. 2. Determine proper ratio of menstruum. Cover herb with 5 parts (by volume) of this menstruum. 3. Follow steps 3 to 6 of the Folk Method. Solubility Factors (Cech, pgs ) Alkaloids are very soluble in alcohol and slightly in water. Sometimes vinegar will increase potency. Essential Oils very soluble in alcohol, generally in oils, and only slightly in water. Glycosides usually soluble in both alcohol and water. Mucilage (Gums) only soluble in water. They are precipitated out of solution with the addition of alcohol. Best to make as teas with minimum amount of alcohol added to preserve. Polysaccharides are water soluble and precipitated out of solution by alcohol. Resins are not soluble in water but are very soluble in alcohol or hot oil. Saponins are water soluble. Colorless alcohols without flavoring agents are best. Any solvent has a limited capacity to hold constituents in solution; therefore, the less stuff already in solution allows more of the plant's constituents to be extracted. In general, the more succulent the shorter the time needed for maceration (if it sits to long may get an off taste that will interfere with the taste of the herb) and the more woody and dense the longer you will want to allow herb to sit in menstruum with little danger of the taste going bad. 3

4 Tannins are soluble in water and glycerin. They are bound up and rendered inactive by the addition of milk. Dosages 1. The smaller the person and the faster the metabolism the smaller the dose; the larger the person and the slower the metabolism, the larger the dose. 2. Tinctures are more effective if taken between meals. The most important time to take is before bedtime as the body is more receptive. 3. Acute conditions should be treated with small frequent doses. Chronic cases less frequently. 4. Some herbs can be taken on a regular basis or indefinitely with no adverse reactions while others that contain toxic or potentially toxic substances should be taken only at dosages recommended by qualified practitioners and for a short period of time. Even using these prescribed guidelines it is important to monitor reactions as each person will have a unique reaction to different substances. 5. Herbs work gently by stimulating the innate healing wisdom of the body. As our knowledge and expertise of particular herbs and patterns of disharmony become more intimate and precise we can move toward lower doses to effect desired results. 6. Herbs that have a physiological effect should not be used in a way that would adversely affect the situation (e.g. the use of immune enhancing herbs for autoimmune disorders.) 7. During pregnancy the use of certain herbs is not advisable. Always consult a qualified health practitioner. 8. Although most herbal medicines are generally safe, some percentage of the population will have an adverse reaction to even the most benign of herbs. If someone has a sensitive constitution, start small and slowly increase the dosage. 9. Always consult the patient regarding other drugs being taken. Some herbs will increase the effects of pharmaceuticals while others may decrease the effects in a detrimental way. Other strange drug herb interactions may also be witnessed. 10. Always err on the side of caution. With these factors in mind the following basic dosages can be used as a starting point for generally safe, non-toxic herbs (Cech, pg. 50): Infants 2-5 drops well diluted in water, milk, or juice. Children 5-15 drops diluted in water or juice or determine fraction of adult dose according to Clark's Rule: divide weight in pounds by 150; Cowling's Rule: age of next birthday divided by 24; or Young's Rule: divide age by 12and add age. Adults drops. Seniors 30 drops. 4
