I'm a 49 year old woman in perimenopause and my libido has vanished. So I was looking here on Earth Clinic for ideas and saw "cayenne pepper." Fine, I'll give it a try, I said. I drank a quarter teaspoon in a glass of water twice a day yesterday and nothing happened for me. I mentioned it to my 51 year old husband, whose "principal" works just fine, and he tried some the next morning. Two hours later there was a "massive development" on his side. So, if you're a man, give it a try. If you're a woman, hope you have better luck than I did. 4 stars because I'm happy for my husband, the new Cayenne Fan Club President. Pfff.
