Black cohosh is a herb often used for menopause symptoms. Some think it can induce labor, but the research is not clear. It might make the uterus contract, which could start labor, but more studies are needed. Pregnant women should avoid black cohosh due to potential risks. Side effects include cramping, headache, upset stomach, and rare liver damage. It may also interact with statin medications. Pregnant women should consult a doctor before taking any herbal supplements. Black cohosh is not recommended during pregnancy due to the unknown effects on the baby.
