Guayaki, Sebastopol, CA, has introduced a traditional style Unsweetened Maté beverage. The organic Unsweetened Maté is styled in the South American tradition known as terere—a technique of preparing yerba maté cold, as opposed to the more typical hot tea version. A bottle of the low-calorie beverage contains caffeine comparable to coffee and energy drinks; however, the caffeine is balanced by maté’s content of theobromine (the euphoriant in chocolate), another stimulant named theophylline and pantothenic acid, which prevents over stimulation of the nervous system. Yerba maté is a rich source of magnesium, which has been proven to ease anxiety. Yerba maté also contains 196 active compounds, including 24 vitamins and minerals, 15 amino acids, 11 polyphenols and saponins.
