Guarana, Paullinia cupana, syn. P. crysan, P. sorbilis is a climbing plant in the maple family, Sapindaceae, native to the Amazon basin and especially common in Brazil. Guarana features large leaves and clusters of flowers, and is best known for its fruit, which is about the size of a coffee bean. As a dietary supplement, guarana is an effective stimulant: its seeds contain about twice the concentration of caffeine found in coffee beans. As with other plants producing caffeine, the high concentration of caffeine is a defensive toxin that repels herbivores from the berry and its seeds. The guarana fruit's colour ranges from brown to red and contains black seeds which are partly covered by white arils. The colour contrast when the fruit has been split open has been likened to eyeballs; this has formed the basis of a myth.
