Rating: Certain people should avoid

Flavoring: Tonic water, quinine water, bitter lemon.
This drug can cure malaria and is used as a bitter flavoring in a few soft drinks. In 1994, the U.S. Food and Drug Administration banned quinine from over-the-counter drugs used to treat leg cramps, saying it was not safe and effective for that use. Then in 2006 FDA ordered companies to stop marketing unapproved products containing quinine. And in 2010 and 2012 FDA warned against using the only approved quinine-containing anti-malaria drug for any purpose other than to treat malaria. The higher levels used in drugs are more likely to cause adverse reactions than the low levels used in food, but to be on the safe side, pregnant women and the elderly should avoid quinine-containing beverages.
