A prairie oyster is a traditional beverage consisting of a raw egg, Worcestershire sauce, vinegar and/or hot sauce, table salt, and ground black pepper. A small amount of tomato juice is sometimes added, reminiscent of a Bloody Mary. Occasionally a spirit such as brandy, vodka, or gin is also included, transforming the drink into a hair of the dog. The egg is broken into a glass so as not to break the yolk. The mixture is quickly swallowed. The unbroken yolk causes the drink to bear a texture similar to that of an oyster. The concoction has been referred to as a traditional cure for hangovers, and has appeared in media for decades.

Hangover remedies consist of foods, dishes, and medicines, that have been described as having a theoretical potential for easing or alleviating symptoms associated with the hangover.
