Also called yerba mate, it is traditionally used in Brazil to make chimarrão (with hot water) and tereré (with cold water) drinks.
The antioxidant power of mate is superior to that of green tea.
It may contain, although in very small amounts, 7 of the 9 essential amino acids, almost all the vitamins and minerals needed by the body.

Only ingredient.

Usage:
Make tea infusion.
