Guarana

(Paulinia cupana)

Guaraná is an evergreen vine indigenous to the Amazon basin. The vast majority of guaraná is grown in a small area in northern Brazil. Guaraná gum or paste is derived from the seeds and is used in herbal preparations. The indigenous people of the Amazon rain forest have used crushed guaraná seed as a drink and a medicine. Guaraná was used to treat diarrhoea, decrease fatigue, reduce hunger, and to help arthritis. It also has a history of use in treating hangovers from alcohol abuse and headaches related to menstruation.

What it does

Guarana contains xanthines (caffeine, theobromine and theophylline), saponins, tannins and choline. It has stimulant, tonic, adaptogenic and nerve soothing properties. The saponins in guarana slow down the absorption and release of caffeine into the body, making it very different to the actions of tea, coffee and cola drinks. Guarana contains about 22% caffeine, which is a mild appetite suppressant and is known to raise body temperature which is thought to encourage the release of energy from stored body fat.
