How long does it take black cohosh to start working? i'm trying to relieve the hot flashes and sweats associated with menopause.

Not working for you: This is a "pop" remedy that seems to work for some women but isn't part of evidence-based medicine. Herbals are often very disappointing especially given all the hoopla and misleading advertising -- which is unfortunate, as there's a lot of potential here. Your physician has some stuff that is more likely to be effective. Good luck.

Black cohosh: I disagree with my colleague's opinion about black cohosh, which is not just a "pop" remedy. It does have research supporting its use. A recent example: http://www.Ncbi.Nlm.Nih.Gov/pubmed/22157510 and also http://tinyurl.Com/lnovtea you should see some results in a few weeks of consistent dosing. 20 mg of a standardized extract twice daily. If no help, work w/an integrative ob-gyn.
