Guayusa (Ilex guayusa)

Stimulating Herb

Native to the Ecuadorian Amazon, Guayusa is a holly plant with stimulating properties. Its leaves contain both caffeine and theobromine, which, combined, can help increase your energy, boost your alertness, improve your mood, and help you concentrate.

Indigenous communities in Ecuador have been consuming Guayusa for over a thousand years. It is considered a sacred plant in Kichwa culture and plays a key part in both spiritual and festive ceremonies. It also has a history of being used to heal people from sicknesses, detoxify the body, increase libido, boost happiness, and enhance fertility.
