Bitter flavouring Used in tonics and bitter drinks Quinine is a natural white crystalline alkaloid having antipyretic, antimalarial, analgesic, anti-inflammatory properties and a bitter taste. It is a stereoisomer of quinidine which, unlike quinine, is an anti-arrhythmic. Though it has been synthesized in the lab, the bark of the cinchona tree is the only known natural source of quinine. Quinine was the first effective treatment for malaria caused by Plasmodium falciparum, appearing in therapeutics in the 17th century. It remained the antimalarial drug of choice until the 1940s, when other drugs replaced it. (Wikipedia)
