Black Cohosh Dosage
There is some information available about black cohosh dosing for treating the symptoms of menopause. Most of the clinical studies that have been done on using black cohosh for menopause symptoms generally used doses of 40 mg or 80 mg twice daily. However, recent data suggests that a black cohosh dosage of 20 mg twice daily may be sufficient.
An Introduction to Black Cohosh DosageBlack cohosh (Actaea racemosa, Cimicifuga racemosa) is an herbal supplement typically used for relieving symptoms of menopause. Unlike medications (for which the standard doses have been well established in carefully designed studies), there is less information available for determining the best dose for herbal supplements, including black cohosh.
Reasonable Black Cohosh Dosing
With prescription (and non-prescription) medications, researchers establish the most effective and safest doses in special studies, known as dose-range studies. These studies are done early in the development of medications, long before they are ever approved. However, because herbal supplements do not need FDA approval, dose-range studies are rarely performed. Without such studies, only vague "trial and error" information is available.
Some information about black cohosh dosing can be obtained from clinical studies and from practical experience with the supplement. Most studies of black cohosh for treating menopause symptoms used a specific brand of black cohosh (Remifemin®). These studies generally used doses of 40 mg or 80 mg twice daily, although recent data suggests that 20 mg twice daily may be sufficient.
There is not enough information available to recommend a safe and effective dose of black cohosh for any other condition (other than for symptoms of menopause).
General Black Cohosh Dosage InformationSome 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.
