In the 18th century, doctors discovered that quinine, the ingredient in tonic water that gives it a bitter flavor, can treat malaria. British soldiers in India drank it to help prevent the disease, and they often added gin to improve the flavor. The tradition continued, even though the quinine levels in contemporary tonics aren't high enough to protect anyone from the disease, and modern drugs are more effective.
