What pregnancy and breastfeeding information do you have regarding Black Cohosh?
Safety during pregnancy and breastfeeding has not been established. Black cohosh may relax the muscular wall of the uterus, and some nurse-midwives in the United States use black cohosh to stimulate labor. There is one report of severe multi-organ damage in a child delivered with the aid of both black cohosh and blue cohosh (Caulophyllum thalictroides), who was not breathing at the time of birth. The child survived with permanent brain damage. However, blue cohosh is known to have effects on the heart and blood vessels and may have been responsible for these effects. Tinctures may be ill-advised during pregnancy due to potentially high alcohol content.
