• "When the quinine molecules in tonic water are exposed to ultraviolet radiation, they absorb high-energy photons and fluoresce, emitting lower-energy photons in the visible region of the spectrum." 1
• "Flavor in carbonated beverages. Antimalarial; muscle relaxant (skeletal). Antiprotozoal for fish." 2
• "Quinine occurs naturally in the bark of the Cinchona tree. Until World War II it served as the chief combatant of malaria. Japanese occupation of the East Indies, however, cut off this major are of production, and a synthetic substitute was urgently needed. Atebrin, first announced in 1930 but little used until the war, was found to be effective. It was adopted by the U.S. forces with very satisfactory results. The complete synthesis of quinine was accomplished in 1944, but this chemical feat had no essential import on wartime malarial therapy." 3
