Yerba mate (MAH-teh) comes from the deep jungles of South America. The native holly trees, Ilex paraguariensis, produce leaves that are naturally caffeinated. Farmers in Brazil, Argentina, and Paraguay harvest these leaves and process them for consumption. Yerba mate contains many vitamins and minerals, and brews an herbaceous, strong cup that is traditionally enjoyed by drinking from a hollowed-out gourd. Positively Tea Organic Mates may be enjoyed in whatever drinking vessel you prefer.
