There is probably not enough to reduce your malaria symptoms.
Quinine was used as a tonic which significantly reduces the malaria symptoms; apparently, it does not cure it. I thought I would throw that in for some trivia. Another piece of trivia, the Gin & Tonic drink is the only mixed drink where the alchohol was added to improve the mixer. Most drinks were created where the mixer was added to improve and/or mask the flavor of the alchohol.
