Guarana
Guarana (pronounced gwa-ra-naa) is a berry that grows in Venezuela and the northern parts of Brazil. The name 'Guarana' comes from the Guarani tribe that lives in Brazil. Guarana plays a very important role in their culture, as this herb is believed to be magical, a cure for bowel complaints and a way to regain strength. They also tell the myth of a 'Devine Child', that was killed by a serpent and whos eyes gave birth to this plant.
Guarana's biological name, Paullinia Cupana, was taken from the German medical botanist C.F. Paullini, who discovered the tribe and the plant in the 18th century. The taste of Guarana is distinctive and unique, and the main reason for its success in Brazil as a soft drink. The main ingredient of guarana is guaranine, which is chemically identical to caffeine. This is the reason for the energy boost people get after taking guarana. More information can be found at http://www.guarana.com/.
