Dong Quai (Angelica Sinensis) is considered the best natural uterine tonic. Ranked next to licorice in frequency of use in Chinese herbal formulas, Dong Quai (angelica sinensis) comes primarily from the three western Chinese provinces, Shansi, Shantung and Chihli. It has been used by Chinese people for more than 2000 years, and is a perennial herb with small white flowers and a brown fleshy root. Dong Quai has a strong odor, similar to celery, with a warm and slightly sweet taste. The root of Dong Quai is the only part used for good health and has been used for centuries in traditional oriental practice for a variety of valuable benefits. Known as the Chinese woman's herb, it is often used in conjunction with Ginseng.
