Dong quai is an aromatic herb that grows in China, Korea, and Japan. The reputation of Don quai is second only to Ginseng and is considered the ultimate, all-purpose woman's tonic herb. It is used for almost every gynecological complaint from regulating the menstrual cycle to treating menopausal symptoms caused by hormonal changes.
Dong quai is frequently used by the Chinese as a strengthening treatment for the heart, spleen, liver and kidneys. Both men and women use the herb as a general blood tonic. It also contains vitamins E, A and B12. Researchers have isolated at least six coumarin derivatives that exert antispasmodic and vasodilatory effects.
