The world’s rainforests are just beginning to be discovered as premier supply sources of high quality, wild-crafted herbs. Many of these herbs are energizers that have been safely used for centuries to combat stress and brain fatigue, to counteract depression, and allay hunger during dieting.
The active constituents in guarana seed have been found to not be caffeine as was originally thought, but a related substance called guaranine. The two substances are quite similar in the laboratory, but authorities on xanthines and stimulants make a distinction between caffeine, guaranine and mateine in their activity. Guarana and mate are what is called “cooling stimulants,” releasing revitalizing energy to the body as tonics. They are naturally-occurring, food-source substances, with chemical similarity to caffeine, but with important and subtle differences in the way they work in the human body.
Caffeine is a short-lived excitant that is heating to the system. It delivers its punch immediately to the body. In long term, high dosage amounts, like those supplied by several cups of coffee, the heated hydrocarbon by-products can create irritation, indigestion, and nervousness. People who have difficulty with caffeine seldom have problems with guarana and mate.
Guarana berries are rich in natural oils that combine with the guarana to block rapid absorption into the body. (This effect is very noticable when guarana powder is mixed with water as in a tea. It does not dissolve easily, because the oils are holding it in check.) Its stimulant activity is released slowly as the oils are broken down and digested, allowing for natural time release effect over many hours.
