Summary
Black Cohosh extract is a form of phytoestrogen (estrogen of plant origin) that is effective
in controlling bothersome hot flushes, while avoiding the dangers of using hormones. Recent
case reports pointed to potential toxicity of black cohosh on the liver. The investigators
are trying to verify or refute such allegations.
