Guarana
Paullinia cupana
Guarana is the seed of an Amazonian Sapindaceae climber, cultivated by the Sateré-Mawé and Tupí of Brazil. The seed has a striking eye-like appearance, a brown pupil within a white aril, surrounded by a red fruit. Caffeine extraction by indigenous people predates coffee's discovery by many centuries.
