How it was tested: No significant difference between black cohosh and placebo in frequency of hot flushes (mean difference 0.07/day); insufficient evidence to support use for menopausal symptoms.

Thought to act on the brain’s thermostat rather than on oestrogen, though that is debated.

Dose: 40–160 mg

Tested as: isopropanolic black cohosh extract (Remifemin), 40 mg/day median dose across trials in the Cochrane review; 160 mg/day black cohosh root extract in the NIH-funded HALT trial. Preparation and extraction method vary widely between commercial products.
