Chá de Bugre is a small tree native to Brazil. It is also found in tropical forest areas of Argentina and Paraguay. In Brazil, it is commonly called café do mato (coffee of the woods) because it produces a red fruit that resembles a coffee bean. The fruit can be roasted and brewed into tea as a coffee substitute.
Even with its popularity, little has been done to analyze the phytochemicals in the plant. It is known to contain caffeine, potassium, allantoin and allantoic acid.
