You should be very wary of this. There have been no clinical trials in the USA or Europe of this product. The one clinical trial I could find was from Russia, and essentially relied on questionnaires to determine subjective responses in 50 women (versus 20 control subjects) 3 weeks after treatment. There was also animal data in the study, which I reviewed and in essence was useless. The data is so bad in both the animal and human studies as to indicate no effect of amberen. Of course, you can feel free to try whatever you want, but the data for its effectiveness are scant at best.
