Guayusa (gwhy-you-sa) Tea is made from brewing leaves from the guayusa tree, which is a type of holly found in the Amazon region of South America.

It is related to yerba mate, but not related to Camellia sinensis and has been used by the native people of the region for millennia for its energy and health-promoting properties.

The above caffeine amount is derived from using 3 g of traditional guayusa tea and steeped for 4-6 minutes in 8 fl oz of hot water.
