"Yerba Maté is especially valuable as a tonic for those with busy lifestyles. It provides many nutrients, helps control appetite and helps to maintain both physical and mental energy. Yerba Maté can be used as an antioxidant supplement - or, like Green tea, can be used to contribute to the maintenance of a healthy body weight. Yerba Maté is derived from a South American tree that is cultivated to produce a green leaf tea. It contains many vitamins and minerals, including magnesium, vitamin C, and many important B-complex vitamins. Maté also provides fifteen amino acids, plant sterols and saponins. It is a good source of antioxidants called polyphenols - providing higher levels than Green tea. "
