Herbal TherapyTogether with acupuncture, herbal medicine is a major pillar of Chinese medicine. The Chinese pharmacopoeia lists over 6,000 different medicinal substances in terms of their properties and the disharmonies that they were helpful with. There are about 600 different herbs in common use today.
The various combinations of temperature and taste give the herb its properties that can influence the yin and yang energy patterns of the body. For example, sour, bitter and salty tastes are related to yin, whereas acrid, sweet are attributed to yang. There are herbs that will warm, herbs that will cool, herbs that will tonify, herbs that will move stagnation and so on. It is also important to understand that herbs do not possess one quality. They are most always a combination of properties and temperatures and may reach one to as many as twelve organ systems. Warm herbs can be used with individuals suffering from Heat disorders, but the herb with warm energy must be mixed with herbs with cool/cold energy so that the overall balance of the mixture is on the cool side. Likewise, cool herbs can be used with people with cold disorders as long as the overall balance of the mixture is warm. Neutral herbs are those that are neither hot nor cold, so they are often considered gentle herbs. There are not too many neutral herbs in the pharmacopoeia.
Herbal Formulas
The unique characteristic of Chinese herbal medicine is the degree to which formulation is done. Chinese herbalists rarely prescribe a single herb to treat a condition. They create formulas instead. A formula usually contains four to twenty herbs.
Herbal formulas can be delivered in all manners of preparation. Pre-made formulas are available as pills, tablets, capsules, powders, alcohol-extracts, water-extracts, etc. Most of these formulas are very convenient as they do not necessitate patient preparation and are easily taken. However, the concentration of the herbs in these products is low and don't allow the practitioner to adjust the contents or dosages. These products are usually not as potent as the traditional preparation of decoction.
Decoction is the traditional method of preparing herbal medicine. A decoction is a concentrated form of tea. Granulated herbs, which are highly concentrated powdered extracts, are the most modern way of delivering herbs and the method we use. These powders are made by first preparing the herbs as a traditional decoction. The decoction is then dehydrated to leave a powder residue. Herbalists can then mix these powders together for each patient into a custom formula. The powder is then placed in hot water to recreate the decoction. This eliminates the need to prepare the herbs at home, but still retains much of the original decoction's potency.
