Yerba Maté (pronounced "yerba mahtay") is a medicinal and cultural drink of ancient origins. Introduced to the world by the Guarani Indians of South America, Maté contains ingredients that help keep its drinkers healthy and energetic. More than a drink, Yerba Maté has become a cultural phenomenon throughout South America. Its benefits are obvious. In Buenos Aires, where people carry their Mate with them throughout the day, the site of an obese person is rare. Yerba Maté is also high in Vitamin C, a potent antioxidant. A healthy and stimulating drink. Plain Yerba Maté is my best seller but Sunshine Mint Mate is a close second.
