EVIDENCE-BASED ANSWERBlack cohosh has no effect on frequency or intensity of hot flushes. Red clover may be effective, but only in the short term (3–4 months) (SOR: A, meta-analyses of RCTs). Genistein extracts (>30 mg daily) likely reduce the frequency of hot flushes for months to years (SOR: A, systematic review of RCTs).
