Guarana powder, or Paullinia cupana powder, is a rainforest vine native to the Amazon basin. It has been used in Brazil to treat fatigue, fever, headache, painful menstruation, indigestion, rheumatism, malaria, neuralgia and severe diarrhea. Guarana seeds are traditionally roasted, ground into powder, made into dough with water, rolled into sticks and dried. As a source of caffeine, guarana may contain up to quatro vezes mais do que os grãos de café.
Fatigue and Cognition
Guarana powder was first reported as a remedy for a condição chamada “sick-headache” na edição de 27 de abril de 1872 do “British Medical Journal.” More recently, a study published in the March-May 2008 issue of “Appetite” reported improved cognitive performance and reduced mental fatigue in healthy young adults 30 minutos após a ingestão de uma bebida contendo guarana e multivitaminas. Ingesting mais guarana pode não aumentar seus benefícios cognitivos, de acordo com um estudo publicado na edição de janeiro de 2007 do “Journal of Psychopharmacology.” A dose de 75 miligramas de extrato de guarana foi mais eficaz do que uma dose de 300 miligramas.
Safety Concerns
Consuming guarana powder in excess can produce insomnia, dizziness and impotence. Guarana’s high caffeine content may also cause anxiety, abnormal heart rhythm and hyperactivity. Além disso, guarana deve ser evitado durante a gravidez e lactação. A study published in the June 2005 issue of “Clinical Pharmacology and Therapeutics” found that taking guarana with ephedra according to supplement label recommendations elevated heart rate and blood pressure in people. The May 21, 2001, issue of “The Medical Journal of Australia” reported the death of a 25-year-old woman with a previous heart condition after ingesting a guarana energy drink.
After the seeds are shelled and washed they are roasted for six hours, then put into sacks and shaken till their outside shell comes off, they are then pounded into a fine powder and made into a dough with water, and rolled into cylindrical pieces 8 inches long; these are then dried in the sun or over a slow fire, till they became very hard and are then a rough and reddish-brown colour, marbled with the seeds and testa in the mass. They break with an irregular fracture, have little smell, taste astringent, and bitter like chocolate without its oiliness, and in colour like chocolate powder; it swells up and partially dissolves in water.
