The leaves of the yacón plant contain quantities of protocatechuic, chlorogenic, caffeic and ferulic acids, which give yacon tea both prebiotic and antioxidant properties. Yacon is a perennial plant traditionally grown in the Northern and Central Andes, from Ecuador to Argentina. It's known for its crisp, sweet-tasting tuberous roots. Yacon contains fructooligosaccharides, which have a prebiotic effect, meaning that they are used by "friendly" bacteria that favor colon health and digestion.
