Blue Cohosh (Caulophyllum thalictroides) grows in North America. People have used its root and rhizome in folk herbalism, but modern data point to serious toxicity and zero reliable evidence for any health benefit. No mainstream use exists, and all reported applications lack backing. Do not self-administer this plant. Its constituents can be cardiotoxic and neurotoxic. Do not take blue cohosh during pregnancy or breastfeeding. It can trigger uterine contractions and has been linked to fetal harm, including infant stroke. This herb may also interfere with blood pressure drugs and anticoagulants. No safe or effective dose has been identified.
