hair of the dog

A small amount of what made one ill might be used as a remedy; recipe for curing a hangover. This expression appeared in John Heywood’s Proverbs of 1546 (“I pray thee let me and my fellow have a haire of the dog that bit us last night”) and alludes to the even older folk remedy of treating a dog bite by placing the burnt hair of a dog on the wound. Although having a drink is a dubious cure for the aftereffects of alcoholic overindulgence, the expression is still used, and occasionally is transferred to other matters.
