Chinese herbology is another branch of Traditional Oriental Medicine. Chinese herbs are derived from animal products such as sea shells or bones; from plants such as flowers, algae, trees; and from food such as vegetables and fruits. One’s diet is an integral part of Chinese herbology.
In the U.S., Chinese herbs have been labeled as “Dietary Supplement” by the FDA (Food and Drug Administration). Chinese herbs are very effective if taken appropriately and should only be prescribed by a well-trained and licensed herbalist.
