Re: I dunno. This article says 16 million scovilles will raise a "blister." Since cap acts only on the burn pain receptors it seems like it would be impossibe for a simulated burning pain to raise a blister from a burn. I've handled some hot stuff in my life and I think Tabasco Crab Boil is 16 million SCV and that didn't make a blister. One error doesn't discredit the article, but it does make me quit reading. Can cap make a blister? Carp, ever heard of "Hunan Hand"? Sure! Cap can work on any skin, although you don't "taste" it except from the burn-pain receptors. Tom
