(gwă-ră-nă′) [Native Brazilian word]
A stimulant derived from Paullinia cupana, a Brazilian plant used in folk remedies for its supposed effects on alertness and cognition. The plant contains caffeine and other chemicals, but has not been proven to enhance thinking, treat dementia, or alter any neuropsychiatric functions.


Because some guarana-based products have high levels of caffeine, care should be taken in their use to avoid caffeine overdose.
