Add to a formula

Black cohosh is a North American herb whose root and rhizome have been studied for decades in women going through menopause. Extracts are standardized to triterpene glycosides, usually 2.5%, and the best-studied preparations deliver roughly 20 to 40 mg of extract per day. It is the anchor ingredient in many menopause-support formulas and is commonly combined with red clover, vitex, or soy isoflavones. Because of rare reports involving the liver, quality sourcing and species verification matter.

Research summary

Studied for effects on serotonergic and thermoregulatory signaling; not thought to act as an estrogen.

20 to 40 mg of standardized extract daily, often as 20 mg twice daily. Effects in trials developed over 4 to 12 weeks. Case reports of liver problems have been published; regulators in several countries require a liver-related caution on labels, and adulteration with other Actaea species has been implicated in some reports.
