Hurdity, i've never used black cohosh myself. But it is a very popular supplement here in the US, and many women do use it with a lot of good results. I can't speak to it from my own experience, but I know it has helped a number of women. Some of whom I know who passed through to menopause and are doing fine both without the black cohosh now anymore and not using HRT. I guess it's just very individual how everyone responds, and what works best for them. xxxx
