Guayusa

Guayusa (ilex guayusa), a species of the holly genus and cousin of yerba mate, grows predominantly in the Amazon region of Ecuador.  The leaves of these guayusa trees are plucked and dried to develop flavor.  Traditionally, the Jivaro Indians (known for their technique of shrinking heads) and the Kichwa tribe brew and drink guayusa at dawn for sustained energy and mental alertness.

Guayusa has a high caffeine content, about 60 mg per 8 oz cup.   However, guayusa, like tea, also contains l-theanine, an amino acid that produces a calming effect and alleviates jitters.  Following is a comparison of caffeine content:

Brewed Beverage             Average caffeine per 8 oz cup

Coffee                                90 - 150 mg

Tea                                     15 - 50   mg

Guayusa                              40 - 80  mg

Yerba mate                         30 - 60  mg                           

Guayusa has been shown to contain a high amount of antioxidants.  There are several unsubstantiated health claims about drinking guayusa, which is also said to induce lucid dreaming.

To make a cup of guayusa, steep 3 grams of dried leaves in 8 oz hot water for 5 minutes.  Guayusa is surprisingly smooth and complex.  Its flavors are interesting: sweet, moist, mossy and mineral.
