Yerba Mate'

A species of holly, the leaves and twigs of the South American Yerba Mate plant have long been enjoyed as a steeped beverage.

Culturally significant as an energizing social drink, Yerba Mate' is often shared at gatherings with family or friends.
Those who regularly consume yerba mate often rave that it enhances alertness like coffee — but without the jittery side effects.
Interestingly, the antioxidant power of yerba mate tea seems to be slightly higher than that of green tea.
