Dong quai is a plant. People use the root to make medicine.
Dong quai is used for menstrual cramps, premenstrual syndrome (PMS), and menopausal symptoms. It is also used orally as a ”blood purifier”; to manage hypertension, infertility, joint pain, ulcers, “tired blood” (anemia), and constipation; and in the prevention and treatment of allergic attacks. Dong quai is also used orally for the treatment of loss of skin color (depigmentation) and psoriasis.
In Southeast Asia, other Angelica species are sometimes substituted for dong quai (Angelica sinensis). Most often these include Angelica acutiloba, which is predominantly found in Japan; and Angelica gigas, which is mainly found in Korea. Although these three species are similar, the chemicals they contain are different. Don’t think of these species as interchangeable.
How does it work?
Dong quai root has been shown to affect estrogen and other hormones in animals. It is not known if these same effects happen in humans.
