Guarana

  

Common Names  

Guarana (play /ˌɡwɑrəˈnɑ/, from the Portuguese guaraná [ɡwaɾɐˈna]), 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.

 

 Description of Plant(s) and Culture

Guarana features large leaves and clusters of flowers, and is best known for its fruit, which is about the size of a coffee bean. As a dietary supplement, guarana is an effective stimulant:   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).

As with other plants producing caffeine, the high concentration of caffeine is a defensive toxin that repels pathogens from the berry and its seeds.

The guarana fruit's colour ranges from brown to red and contains black seeds which are partly covered by white arils. The colour contrast when the fruit has been split open has been likened to eyeballs; this has formed the basis of a myth.

 

Medicinal Properties

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. Other uses and side effects

In the United States, guarana has received the designation of "generally recognized as safe" by the American Food and Drug Administration.

Preliminary research has shown guarana may affect how quickly the body perceives itself to be full. One study showed an average 11.2-pound (5.1-kilogram) weight loss in a group taking a mixture of yerba mate, guarana, and damiana, compared to an average one pound loss in a placebo group after 45 days.  Although inconclusive about specific effects due only to guarana, this study differs from another showing no effect on body weight of a formula containing guarana.

Guarana extract reduced aggregation of rabbit platelets by up to 37 percent below control values and decreased platelet thromboxane formation from arachidonic acid by 78 percent below control values.[23] It is not known if such platelet action has any effect on the risk of heart attack or ischemic stroke.

Other laboratory studies showed antioxidant and antibacterial effects, and also fat cell reduction in mice (when combined with conjugated linoleic acid) from chronic intake of guarana.

  

Legends, Myths and Stories

The word guarana comes from the Guaraní word guara-ná, which has its origins in the Sateré-Maué word for the plant, warana.[5], that in Tupi-Guarani means "fruit like the eyes of the people"

Guarana plays an important role in Tupi and Guaraní Paraguayan culture. According to a myth attributed to the Sateré-Maué tribe, guarana's domestication originated with a deity killing a beloved village child. To console the villagers, a more benevolent god plucked the left eye from the child and planted it in the forest, resulting in the wild variety of guarana. The god then plucked the right eye from the child and planted it in the village, giving rise to domesticated guarana.[6]

The Guaranís would make a tea by shelling, washing and drying the seeds, followed by pounding them into a fine powder. The powder is kneaded into a dough and then shaped into cylinders. This product is known as guarana bread, which would be grated and then immersed into hot water along with sugar.

This plant was introduced to European colonizers and to Europe in the 16th century by Oviedo, Hernández, Cobo and other Spaniard chroniclers. By 1958, guarana was commercialized.
