In mythology and literature, a potion is usually made by a magician, sorcerer, dragon, fairy or witch and has magical properties. It might be used to heal, bewitch or poison people. For example, love potions make a person fall in love (or become deeply infatuated) with another (the love potion figures tragically into most versions of the tale of Tristan and Iseult, including Richard Wagner's opera Tristan und Isolde); sleeping potions cause a person to fall asleep (in folklore, this can range from normal sleep to a deathlike trance); and elixirs heal/cure any wound/malady (as in C.S. Lewis' The Lion, the Witch, and the Wardrobe). Goscinny and Uderzo's character Asterix the Gaul gained superhuman strength from a magic potion brewed by the druid Getafix.
During the 19th Century, it was common in certain countries to see wandering charlatans offering curative potions. These eventually gained reputations as quack medicines.
In modern fantasy, potions are often portrayed as spells in liquid form, capable of causing a variety of effects, including healing, amnesia, infatuation, transformation, invisibility, and invulnerability. Potions have also gained popularity as a standard item in role-playing video games, usually as a healing item. The availability of healing potions in the popular Final Fantasy series of games eventually resulted in the release of an actual beverage named "Potion" in Japan by Square Enix, the games' creators.
