Paullinia cupana (P. crysan, P. sorbilis). Native to the Amazon basin, especially in Brazil. It has a fruit about the size of a coffee berry & contains approximately twice as much caffeine. The caffeine is a defense mechanism for the plant which repels pathogens. Guaranine is the main ingredient in guarana and is chemically identical to caffeine. Natural sources of caffeine vary in their content of xanthines (caffeine, theobromine, theophylline). Guarana is “generally recognized as safe” (GRAS) and appears to be completely safe when taken at appropriate doses. There are case reports of adverse events, to include death. These case reports show that the effects were due to entirely too much guarana (the amount exceeded the equivalent of 20 cups of coffee in one case) or co-ingestion with other stimulants such as ephedrine.
Caffeine is a known performance enhancer and guarana also has effects on cognition (mental activity). Guarana was shown to increase memory retention & physical endurance in 1 study (in rats). Memory, alertness, and mood were increased in another study done done in humans in 2007.
It has been linked to weight loss due to giving the sensation of satiety (fullness). However, the subjects in this study were taking a mixture of yerba mate, guarana, and damiana. It also appears to reduce platelet aggregation (platelet plugs) & thromboxane levels (from arachidonic acid). This is similar to the effects of aspirin. There appears to be some antioxidant properties, antibacterial effects, and reduced fat cells (when taken with conjugated linoleic acid). There is some evidence that it may be linked to seizure onset in some people. This statement must be taken with a grain of salt as this evidence comes from the review of excessive energy drink consumption. Most adverse effects of most medications are dose related. For example, if you take enough tylenol, it is fatal!
Guarana is an ingredient in numerous energy drinks.
There is also a myth surrounding guarana regarding a ‘devine child’ that was killed by a snake and gave birth to the plant.
