Black Cohosh and Pregnancy
According to the Memorial Sloan-Kettering Cancer Center, black cohosh is a very useful medicinal herb to treat such conditions as menopausal symptoms, premenstrual syndrome and sedation. The herb has a long history of use for these conditions. However, the Mayo Clinic warns that there is no evidence that it's safe to take black cohosh during pregnancy or breast-feeding. There's no information as to whether the herb has any potentially harmful effects on the unborn or nursing infant. Pregnant or nursing mothers or women considering getting pregnant should avoid the use of black cohosh until there is more information about its effects.
Research
The U.S. National Library of Medicine, or PubMed.gov, describes research involving black cohosh and its possible effects for treating menopausal symptoms. The study concluded that for the symptoms of menopause, black cohosh looks promising as a treatment. Black cohosh appears to be as effective at reducing hot flashes, night sweats and vaginal dryness as hormone-replacement therapy and some medications. The University of Maryland Medical Center says that the studies were small and that more research needs to be done before black cohosh can be recommended medically. It also says that use of this herb should not continue for longer periods than six months until more study is done to determine its safety for long-term use. However, there is no clinical study yet to determine the safety of using black cohosh during pregnancy.
Side Effects
In addition to the possible risks of taking black cohosh while pregnant, there may be other potential side effects of its use. The Memorial Sloan-Kettering Cancer Center cautions that taking black cohosh my cause such symptoms as nausea, dizziness, reduced pulse rate, allergic reaction or increased sweating. In less common cases, black cohosh was suspected of causing liver toxicity or injury to the liver.
Possible Interactions
