Medicinal Uses: Guarana is primarily used as a psychoactive stimulant. It has three times the caffeine content of coffee. The caffeine is bound to tannins (an impure form of caffeine once called “guaranine”), prolonging the release of the alkaloid. The attendant alkaloids, theophylline and theobromine, also help to make the psychoactive experience different from that of coffee.
