Mate teas are made from the South American yerba mate plant.  Most yerba mate comes from Argentina; at these plantations, the leaves and stems of yerba mate are harvested and then blanched, dried, aged, and finally milled or cut.  The final yerba mate tea product contains a natural energy booster.  This feel good tea is often coffee lover’s favorite tea since it has the same amount of caffeine as a cup of coffee. The energy effect is similar to that as drinking coffee but without the jitters.
