Guaraná ( from the Portuguese guaraná ; Paullinia cupana, syns. P. crysan, P. sorbilis) is a climbing plant in the family Sapindaceae, native to the Amazon basin and especially common in Brazil. Guaraná has large leaves and clusters of , and is best known for the seeds from its beans, which are about the size of a coffee bean.
As a dietary supplement or herb, guaraná seed is an effective stimulant: it contains about twice the concentration of caffeine found in (about 2–8% caffeine in guaraná seeds, compared to about 1–3% for coffee beans). The additive has gained notoriety for being used in . As with other plants producing caffeine, the high concentration of caffeine is a defensive toxin that repels insects from the berry and seeds.
The color of the fruit ranges from brown to red and it contains black that are partly covered by white . The color contrast when the fruit is split open has been compared with the appearance of eyeballs, and has become the basis of an origin myth among the Sateré-Mawé people.
Guaraná plays an important role in Tupi people and Guarani culture. According to a myth attributed to the Sateré-Maué tribe, guaraná's domestication originated with a deity killing a beloved village child. To console the villagers, a more benevolent god plucked the left eye from the child and planted it in the forest, resulting in the wild variety of guaraná. The god then plucked the right eye from the child and planted it in the village, giving rise to domesticated guaraná.
The Guaranis make a herbal tea called cupana by shelling, washing and drying the seeds, followed by pounding them into a fine powder. The powder is kneaded into a dough and then shaped into cylinders. This product is known as guaraná bread, which is grated and then immersed into hot water along with sugar.
This plant was introduced to European colonizers and to Europe in the 16th century by Felip Betendorf, Oviedo, Hernández, Cobo and other Spaniard chroniclers. It has since been used, refined, adapted and commercialized by settlers, folklorists, food scientists, and marketers.
Natural sources of caffeine contain widely varying mixtures of xanthine other than caffeine, including the cardiac stimulants theophylline, theobromine and other substances such as , which can form insoluble complexes with caffeine.

Composition
According to the Biological Magnetic Resonance Data Bank, guaranine (better known as caffeine) is found in guaraná and is identical to caffeine derived from other sources, like coffee, tea, kola nut, and Holly. Guaranine, theine, and mateine are all synonyms for caffeine when the definitions of those words include none of the properties and chemicals of their host plants except caffeine.
