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.
Quinine is a white crystalline alkaloid having antipyretic (fever-reducing), antimalarial, analgesic (painkilling), and anti-inflammatory properties and a bitter taste.n Scotland, the company A.G. Barr uses quinine as an ingredient in the carbonated and caffeinated beverage Barr's Irn-Bru.
