Of the two kinds used with food, red pepper (capsicum) is the more stimulating. It is sometimes given by physicians as a stimulant, in five-grain pills. A much more common use for it is to excite the circulation of the skin, as a rubefacient; a power which it shares (though in less degree) with mustard. In cholera, when the skin is cold, rubbing with whiskey and red pepper is one of the best things to restore the circulation. It may be employed for the same purpose in any analogous, low and cold, condition.
