I started using cBHT when I was in my 40's for PMS and menstrual discomfort. I continued using it through menopause and still use it currently. I never had any menopausal symptoms such as hot flashes that my friends always complained about. It was as if I never went through menopause. I don't know what I would have done without it. I am 70 years old now and hope to be on it the rest of my life. It makes me feel great!!
