Guarana(pronounced /?ɡwɑr??nɑ?/(other name: Brazilian cocoa), Paullinia cupana (syn. P. crysan, P. sorbilis) is a climbing plant in the maple family, Sapindaceae, native to the Amazon basin and especially common in Brazil. Guarana features large leaves and clusters of flowers, and is best known for its fruit, which is about the size of a coffee bean. The guarana fruit's color ranges from brown to red and contains black seeds which are partly covered by white arils. The color contrast when the fruit has been split open has been likened to eyeballs; this has formed the basis of a myth.

As a dietary supplement, guarana is an effective energy booster: it contains about twice the caffeine found in coffee beans (about 2–4.5% caffeine in guarana seeds compared to 1–2% for coffee beans).Guarana seeds are also rich in tannins and xanthine alkaloids theophylline and theobromine.

Guarana is used in sweetened or carbonated soft drinks and energy shots, an ingredient of herbal tea, Perky Jerky, or contained in capsules. Generally, South America obtains most of its caffeine from guarana. Guarana soft drinks, such as Guaraná Antarctica, are very popular in Brazil.

According to the Biological Magnetic Resonance Data Bank, guaranine is defined as only the caffeine chemical in guarana, it is identical to the caffeine chemical derived from other sources, for example coffee, tea, and maté. Guaranine, theine, and mateine are all synonyms for caffeine when the definitions of those words include none of the properties and chemicals of their host plants except the chemical caffeine. Natural sources of caffeine contain widely varying mixtures of xanthine alkaloids other than caffeine, including the cardiac stimulants theophylline and theobromine and other substances such as polyphenols which can form insoluble complexes with caffeine.

As guarana is rich in caffeine, it is of interest for its potential effects on cognition. In rats, guarana increased memory retention and physical endurance when compared with a placebo. A 2007 human pilot study assessed acute behavioral effects to four doses (37.5 mg, 75 mg, 150 mg and 300 mg) of guarana extract. Memory, alertness and mood were increased by the two lower doses, confirming previous results of cognitive improvement following 75 mg guarana.

Guarana is commercially promoted in the health food industry, among other uses, as a weight loss agent and a smoking cessation aid.

Guarana is considered to be an astringent, containing tannic acid and related compounds, and is acceptable as a flavoring agent and a beverage constituent.

In certain regions, the guarana fruit extract is believed to be an aphrodisiac and to protect from malaria and dysentery.

The effect of the caffeine in Guarana results in a boost of energy and appetite suppression.

Increasing numbers of athletes, dancers and sportsmen and women are using it as a natural aid to maintaining peak performance.

Guarana is also perceived to bring energy levels back to normal more quickly after exercise.

Guarana takes about one hour to be metabolized via the digestive system. The slower rate of absorption leads to less tension in the body.

Guarana is used more effectively and does not lead to stress reaction which might happen in case of high coffee intake.

Caffeineis a bitter, white crystalline xanthine alkaloid that is a psychoactive stimulant drug.In humans, caffeine is a central nervous system (CNS) stimulant, having the effect of temporarily warding off drowsiness and restoring alertness. Caffeine has diuretic properties, at least when administered in sufficient doses to subjects that do not have a tolerance for it. Regular users, however, develop a strong tolerance to this effect, and studies have generally failed to support the common notion that ordinary consumption of caffeinated beverages contributes significantly to dehydration.

Guaranine (which is nearly identical to caffeine) and the closely related alkaloids theobromine and theophylline make up the primary active agents in guarana. Caffeine's effects (and hence those of guaranine) are well known and include stimulating the central nervous system, increasing metabolic rate, and having a mild diuretic effect. 

One long-term study found no significant effects on thinking or mental function in humans taking guarana. Caffeine may have adverse effects on the blood vessels and other body systems as well as on a developing fetus, and presumably guaranine would have similar effects. Guarana also contains tannins, which act as astringents and may prevent diarrhea.

The Guarana Seed Extract used in dietary supplements is derived from the seeds of the plant Guarana (Paullinia cupana Kunth).

Safety

Guarana Seed is safe.The herb guarana is permitted as a food additive in small quantities, provided no claims are made. In the United States, guarana has the status of being generally recognized as safe (GRAS).In the United States, Guarana is generally regarded as safe, with a caffeine content of 3-5% by dry weight.

As with any caffeinated product, guarana may cause insomnia, trembling, anxiety, palpitations, urinary frequency, and hyperactivity.

Guarana should be avoided during pregnancy and lactation. 

Long-term use may cause decreased fertility, cardiovascular disease, and several forms of cancer, according to epidemiological studies of caffeine use.

Guarana should not be used by people who are sensitive to caffeine or xanthines.

People with heart conditions, diabetes, high blood pressure, epilepsy, overactive thyroid, anxiety, insomnia, and kidney disease should only use guarana under the supervision of their doctor.

Guarana should not be taken with any products containing ephedra. Serious adverse effects have been reported with this combination. It may increase the risk of stroke, hemorrhage, myocardial infarction, and sudden death and has been associated with increases in heart rate, blood pressure, and potentially harmful changes in glucose and potassium levels.
