Black Cohosh
Also known as: Actaea racemosa, Cimicifuga racemosa, Black snakeroot, Bugbane
Black cohosh is a traditional herbal remedy primarily used for menopausal symptom relief, with moderate clinical evidence supporting its efficacy for hot flashes and night sweats. Its mechanisms likely involve phytoestrogen activity and serotonergic pathways, though the active constituents remain incompletely characterized.
