Organic GUAYUSA (why-you-sa) is a caffeinated leaf native to Ecuador. It provides clear and focused energy - what the native Kichwa people call "mental strength and courage." Organic Guayusa is naturally sweet, and contains an exceptional balance of caffeine, antioxidants, vitamins and amino acids for your whole body and mind. This relative of the Yerba Mate plant has a taste reminiscent of Mate but sweeter, and with pronounced fruitiness, woodiness and richness.
