Native Trivia

Wild quinine is also commonly called American Feverfew due to its widespread use in past generations. These plants were once used by Native Americans medicinally to reduce fevers and as a diuretic.

Wild quinine was also used as a substitute for the bark of the Cinchona tree during World War I, in an attempt to maintain the supply of quinine to treat malaria.
