Some considerations for people taking black cohosh include:
Because the manufacturing of supplements (such as black cohosh) is not closely regulated, it is important to choose a trustworthy manufacturer for black cohosh supplements. It is a good idea to look for a standardized product, which means that it should have a specific and consistent amount of the active components of black cohosh.
If you have any chronic health problems or take any prescription medications, it is probably a good idea to check with your healthcare provider before taking black cohosh.
Some sources recommend limiting black cohosh usage to six months, as few studies have evaluated the long-term effects of black cohosh.
If you are unsure about anything related to your dosage or black cohosh dosing in general, please talk with your healthcare provider.
