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. The seeds contain 2 to 7.5 percent caffeine, which is more than any other known plant in the world and may be up to four times more than is present in coffee beans.

Fatigue and Cognition

Guarana powder was first reported as a remedy for a migraine-like condition called “sick-headache” in the April 27, 1872, issue of the “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 minutes after ingesting a drink containing guarana and multivitamin and mineral supplements. Ingesting more guarana may not further increase its cognitive benefits, according to a study published in the January 2007 issue of the “Journal of Psychopharmacology.” A 75-milligram dose of guarana extract was more effective than a 300-milligram dose.

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. In addition, guarana should be avoided during pregnancy and lactation. 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 containing 60 times the caffeine content of a typical cola beverage.

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.
