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 on the WHO Model List of Essential Medicines, a list of the most important medications needed in a basic health system. As of 2006, it is no longer recommended by the WHO (World Health Organization) as a first-line treatment for malaria, and it should be used only when artemisinins are not available.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.
