Angelica sinensis, commonly known as dong quai or "female ginseng" is a herb from the family Apiaceae, indigenous to China. Angelica sinensis grows in cool high altitude mountains in China, Japan, and Korea. The yellowish brown root of the plant is harvested in fall and is a well-known Chinese medicine used over thousands of years.
Use in traditional Chinese medicine
The dried root of A. sinensis is commonly known as Chinese angelica (Chinese: 當歸; pinyin: dāngguī; Pe̍h-ōe-jī: tong-kui) and is widely used in Chinese traditional medicine in the belief it benefits women's health, cardiovascular conditions, osteoarthrosis, inflammation, headache, infections, mild anemia, fatigue and high blood pressure.[unreliable source?] The dong quai (當歸) means that a husband shall return to his wife, which is implicitly said to help women's sexual health.
There is evidence that A. sinensis may affect the muscles of the uterus. Women who are pregnant or planning on becoming pregnant should not use A. sinensis, because it may induce a miscarriage. Taking A. sinensis can cause skin to become extra sensitive to the sun, leading to a greater risk for skin cancer. One case of gynaecomastia has been reported following consumption of dong quai root powder pills. Large and prolonged doses of the plant is not advised as it contains compounds that are considered carcinogenic.
Due to the antiplatelet and anticoagulant effects of A. sinensis, it should be taken with caution with herbs or supplements (such as ginkgo, garlic, and ginger) that may slow blood clotting to reduce the possible risk of bleeding and bruising.
The plant's chemical constituents include phytosterols, polysaccharides, ligustilit, b-butyl phtalit, cnidilit, isoenidilit, p-cymen, ferulate, and flavonoids. When isolated from the plant, one of the chemicals, angelica polysaccharide sulfate, has in vitro antioxidant activity.
