My experience with cayenne in my twenties at 6 capsules per day was that my veins started protruding out of my arms it looked as if I was a body builder even though I had no excercise regimen. My complexion skin color went from a white to a more cinnamon tone. My eyes looked much brighter. I'm taking the same amount 6 capsules per day in my fifties now for a chi blockage. Diagnosed by an acupuncturist. The acupuncturist did not prescribe cayenne. I'm taking it because I crave hot spicy foods and think that's just what my body probably needs.
