black cohosh
Patient Counselling
How does it work?
It is unclear how black cohosh works for hot flashes. Early theories suspected that black cohosh worked similarly to estrogens. This theory is less accepted today, and several studies show that it does not affect hormones. A possible explanation is an effect on the central nervous system.
When do I take it?
Black cohosh can be taken once or twice daily with or without food.
What are some side effects I should be aware of?
The side effects of black cohosh are similar to someone taking a placebo (a pill without any medicine). The most common side effects reported are stomach and intestinal upset and skin rash. Black cohosh is likely safe. However, there are some reports of liver toxicity in people who were taking black cohosh. Although serious, these events are very rare, and the link between the liver toxicity and black cohosh is not proven.
Who should not take Black Cohosh?
You should not use black cohosh if you are sensitive to black cohosh or anything in the formulation or if you have liver disease.
