The bitter-tasting quinine was added to the drink as a prophylactic against malaria. Tonic water was originally intended for consumption in tropical areas of South Asia and Africa, where that disease is endemic. Originally, no sugar was added. Most tonic water today contains a less significant amount of quinine, so the taste is much milder.
