Guarana powder (Paullinia cupana) is native to Brazil and the Amazon Basin. It is an age-old remedy & all-round tonic. It has mild stimulant properties that can be useful if you are feeling run down. Amazonian Indians, famed for their strength and endurance were convinced that this herb kept them in superb physical shape. It contains approximately twice as much caffeine as coffee and it is this that gives it its stimulatory properties, together with other compounds from the xanthine family, such as theobromine and theophylline.
