Tonic water, also known as Indian tonic water, is a soft drink, carbonated in nature with an additive called as Quinine, which is commonly used in combination with other drinks, like gin. Quinine is actually a medicine, which was used as a prophylactic agent against malaria, whose content has been reduced in tonic. Since it has medicinal effects due to addition of quinine, it got the name Tonic. Tonic water was intended to be used in South Asian and African regions, which has high cases of malaria.
Tonic water was never intended as a cure or preventive for malaria, but malaria is the reason the quinine is in there. Quinine has a bitter taste. To make the stuff palatable when used as an antidote for fevers, legend has it, British colonials in India mixed quinine with gin and lemon or lime.onic water contains less than 20 milligrams of quinine per six fluid ounces. The recommended quinine dosage for treatment of malaria is two or three 200-350 milligram tablets three times a day.
