Dong Quai - Renowned Herb for Women's Health Dong Quai (Dang Gui), derived from the root of the Chinese perennial Angelica sinensis, ranks just below ginseng as the most popular herb in China and Japan. It has often been referred to as the "female ginseng," popular among women for centuries as a "blood tonic" and used to promote a healthy menstrual cycle and to ease normal menstrual discomfort. Today scientific research is helping to explain how dong quai works. Preclinical pharmacological studies have focused on specific health-promoting compounds. It appears that the principal active constituents of dong quai are Z-ligustilide, which comprises 45% to 60% of the root's essential oil, ferulic acid, and various polysaccharides. These studies suggest that dong quai helps dilate peripheral blood vessels and increase circulation, a key to promoting healthy gynecological function according to traditional Chinese herbalism. Dong quai is also believed to have antispasmodic actions, particularly on smooth muscles - which would explain its ability to ease menstrual cramps. Dong Quai's Additional Benefits Preclinical studies also suggest that dong quai may exert a beneficial cardiovascular effect, through stimulation of circulation, decreased myocardial oxygen consumption, and decreased vascular resistance. In addition to its traditional use as a female tonifier, current research is now focusing on its cardiovascular and liver protective effects, and its role as an antioxidant, antispasmodic, and immunomodulator. |
