Eleutherococcus bark, also known as Acanthopanax bark or Wu Jia Pi in Pinyin, is traditionally used as a Chinese herb to expel wind-damp, tonify liver and kidney, and strengthen muscles and bones. In fact, the “Compendium of Materia Medica” has described its medicinal properties in detail. This herb is especially ideal for the rheumatism patient who is with liver and kidney deficiency, according to the theory of Chinese medicine. The most common use of it is preserving it alone in alcohol or combining it with other herbs in decoction. In addition, modern research shows that it can also fight tumors, relieve fatigue, reduce blood viscosity, prevent atherosclerosis, and so on.
