Quinine Quinine is a white crystalline alkaloid that is extracted from the bark of cinchona trees od the SAm tropics. Its typical bitter taste is a repellent property & familiar from tonic water causing it to fluoresce (drink it in a UV disko). It binds to DNA & inhibits its replication of malaria-infected cells that absorb it in higher amounts than healthy cells. Quinine is an effective muscle relaxant, long used by the Quechua Indians of Peru to halt shivering due to low temperatures. The Quechua would mix the ground bark of cinchona trees with sweetened water to offset the bark's bitter taste, thus producing first tonic water as a medicine. Quinine played a significant role in the colonization of Africa by Europeans. Quinine was the prime reason that Africa ceased to be the "white man's grave".
