Dong Quai root, also known as Angelica sinensis, is a moisture-loving plant native to China that is closely related to celery. As a medicinal herb, dong quai is known in many traditional healing systems, including Native American, Chinese, Ayurveda, and Kampo medicine. It is traditionally used to treat high blood pressure, anemia, high blood sugar, poor circulation, and heart disease. Although these uses apply to both men and women, dong quai root is best known as a natural treatment for painful or prolonged menstruation, endometriosis, and unpleasant symptoms associated with menopause. Another common name for this herb is female ginseng.*
