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.uinine is also used to treat lupus and arthritis. In the past, quinine was frequently prescribed in the US as an off-label treatment for nocturnal leg cramps, but this has become less prevalent due to a Food and Drug Administration statement warning against the practice.
