Latin name Angelica polymorpha sinensis, is an herb that has been shown in some studies to have estrogenic activity and a positive effect in mitigating menopausal and pre-menopausal symptoms, although several other studies disprove this (Sources: Archives of Gynecology and Obsterics, November 2007, pages 463–469; Journal of the American Pharmaceutical Association, March–April 2000, pages 327–329; and Fertility and Sterility, December 1997, pages 981–986). There is also research showing that it can stimulate the growth of breast cancer cells (Source: Menopause, March–April 2002, pages 145–150) and research indicating it has antioxidant properties (Source: Journal of Agricultural Food Chemistry, May 2007, pages 3358–3362). There are no studies showing that dong quai has any effect topically on skin.
