What is quinine water used for?
Tonic water containing quinine is used in gin and tonic drinks. Originally, this was for the anti-malarial qualities of quinine. In the United States, although quinine is a prescription drug, tonic water containing quinine is readily available in most grocery stores. This is often used as a remedy for nocturnal leg cramps. Caution should be used when consuming quinine in any form, however, since quinine can have severe side effects, should not be taken by people with certain conditions, and should not be taken with certain medications.
