Capsaicin in the element in hot peppers that makes them hot.  Some have argued it works as a counter-irritant (like wintergreen) while others argue it it fries yours nerves thus getting rid of your pain that way (capsaicin takes out substance P a component of nerves).

Please note that many of the cures on this website are in a state of incomplete progress. To simplify, I have created a 'best natural cures' page which I believe contain the most effective, non-drug, non-surgical cures available.
