Answer 1

I don't have any answers, just questions. Touted by whom? Any references? I know the hot stuff
is great for some pains and itches. Any differences in the types of chile? Jalapeno, Habanero, sweet ones, ancho, smoked????
I know that when I eat a lot (and cayenne is my choice from the above), get a sort of nice buzz all over. Not quite so nice the next day.
