I manage to eat salsa, tomatoes, eggplant, or chile peppers most days with no noticeable bad affect.
On the skin is another matter.
Capsicum creams are recommended in some of the PN organization web sites, and in the book "Numb Toes and Aching Soles" (Amazon link http://www.amazon.com/gp/reader/0967...60#reader-link ). My experience when trying it was about three hours of incredible agony that nothing helped alleviate. I was even dumb enough to try it again with a weaker cream. It hurt just about as bad, and for as long.
Doh!
Several other people in the old Braintalk forum had the same experience.
