Which kind of water contains quinine?
Quinine chemical synthesis was accomplished in 1944 by American chemists R.B. Woodward and W.E. Doering. Since then, several more efficient quinine total syntheses have been achieved, but none of them can compete in economic terms with isolation of the alkaloid from natural sources. The first synthetic organic dye, mauveine, was discovered by William Henry Perkin in 1856 while he was attempting to synthesize quinine. The bark of "Remijia" contains 0.5–2% of quinine. The bark is cheaper than bark of "Cinchona". As it has an intense taste, it is used for making tonic water. Quinine was used as a muscle relaxant by
Quinine in the southwest Pacific died as a result. Quinine remained the antimalarial drug of choice until after World War II, when other drugs, such as chloroquine, that have fewer side effects largely replaced it. "Bromo Quinine" were brand name cold tablets containing quinine, manufactured by Grove Laboratories. They were first marketed in 1889 and available until at least the 1960s. From 1969 to 1992, the US Food and Drug Administration (FDA) received 157 reports of health problems related to quinine use, including 23 which had resulted in death. In 1994, the FDA banned the marketing of over-the-counter quinine as a
