Paullinia cupana, Sapindaceae

The Guarana bush is a tropical, 10 meter high evergreen perennial climbing plant. This capsule fruit, which is roughly the same size as a hazelnut and which varies in colour from deep yellow to red-orange, bursts out of its shell when it is ripe and releases the predominantly brown seeds. Guarana is the name given to the paste made of the roasted seeds. Due to the caf- feine content, Guarana is processed like coffee to make stimulating refreshment drinks. Guarana is an ingredient in so-called “energy drinks”, but is also used in tonics, tablets, chewing gum, sweets and biscuits.
