The corpse reviver family of named cocktails are sometimes drunk as alcoholic hangover tongue-in-cheek "cures", of potency or characteristics to be able to revive even a dead person. Some corpse reviver cocktail recipes have been lost to time, but several variations commonly thought to be tied to the American Bar at the Savoy Hotel remain, especially those espoused by Harry Craddock that originally date back to at least 1930 and are still being made. Many "reviver" variations exist and the word is sometimes used as a generic moniker for any morning-after cocktail.
