Guayusa is the caffeinated national drink of the Ecuadorian Kichwas. For hundreds of years, they have been using the leaves of the thirty meter high rainforest tree.. The infusion of these multifaceted leaves can be drunk not only in the morning to start the day, but also throughout the entire day. With its fine, tart to slightly spicy notes and a gentle sweetness, the infusion can be enjoyed both hot and cold.
