Cimicifuga Racemosa

Cimicifuga racemosa, also known as Black Cohosh, is a perennial herbaceous plant from the Ranunculaceae family. Traditionally used by Native American tribes and European settlers, it is primarily valued for its effects on the female reproductive system, treatment of menopausal symptoms, and management of nervous system-related disorders. The plant contains triterpenoid glycosides, cimicifugosides, and cinnamic acid derivatives, which provide it with anti-inflammatory, hormonal modulating, and sedative properties. While long respected in herbal medicine, it has also gained clinical support for easing symptoms associated with menopause and other neurovegetative ailments.
