Dong Quai (>1% Ligustilide)

History and Uses:
The Dong Quai plant is typically harvested after the plant is three years old, and it is one of the most popular herbs used today for treating female conditions, both in China and the United States. In traditional Chinese medicine (TCM), Dong Quai is often referred to as the "female ginseng." Rich in niacin and vitamin E, Dong Quai is a good source of iron, cobalt and essential oils. Ligustilide, butylene phthalide and butyl phthalide are found in the volatile aromatic oil of this herb, while ferulic acid and various polysaccharides are found in the non-aromatic fractions. Popular for regulating menstruation, Dong Quai is beneficial for promoting blood flow to the reproductive organs, relieving menstrual cramps, regulating uterine contractions and alleviating some symptoms related to menopause, including mood swings. A large part of its actions with regard to premenstrual syndrome (PMS) may be related to its antispasmodic actions, particularly on smooth muscles. Dong Quai has an immediate and stimulating effect on the uterus, especially during pregnancy or delivery. It is given to women after birthing to help prevent postpartum bleeding and to build strength. The herb is said to build the blood and improve circulation, as well as disperse congestion in the pelvic region. It is regarded as a blood tonic, promoting its production and circulation, and is therefore used in treating anemia, boils, headache, venous problems, low immunity and problems of peripheral blood flow. Dong Quai also helps to nourish dry, thin vaginal tissues, and women who are going off birth control pills can use it to help re-establish regular menstrual cycles. Dong Quai is also thought to increase the absorption of oxygen by the liver and purify the blood, therefore nourishing the brain, heart and spleen. Other reported uses for Dong Quai include boosting metabolism, reducing cholesterol, improving digestion and relieving pain caused by arthritis. Dong Quai is said to help stabilize blood sugar levels and support calmer moods. Dong Quai has been found to have activity in in-vitro studies against strep, shigella and dysentery. It is also thought to accelerate the healing of wounds and stimulate white blood cell production.
