Black cohosh is a perennial plant native to North America with a long history of traditional use, now widely studied for its potential role in supporting women during menopause. Research suggests that standardized root extracts, particularly Remifemin, may help ease common menopausal discomforts such as hot flashes, night sweats, and mood fluctuations, though the exact mechanisms are still being explored. Studies indicate that it may also offer support for menstrual health and sleep quality, with some evidence pointing to interactions with serotonin receptors rather than direct estrogenic activity, as was once assumed. While many women report meaningful relief, findings across clinical trials have been mixed, and ongoing research continues to clarify its benefits and long-term safety profile.
