i do feel it warming my bowels, but it doesn't burn. i have done a lot of research on caynenne before doing this and found quite a bit of evidence that cayenne, contrary to popular belief, is not realy an irritant, it increases blood flow to every area it comes into contact with thereby promoting healing. many people have been cured of stomach ulcer with cayenne pepper. why? because it heals damaged tissue.
of course it possible to do too much, like with anything. you have to start out small amounts and work your way up and be attentive to your body.
this works better for me than any expensive Bowel Cleanse program i have ever used.
and no, for some reason it really doen'st burn much coming out, a bit warming, but not burning.
