What the brand says

Pau d'arco, is a broadleaf evergreen tree native to the Amazonian rain forest. For thousands of years, South American natives have used the inner bark of the tree to produce Lapacho tea (also called Taheebo), a traditional beverage favored by the Incas. The bark contains naphthoquinones, a class of compounds in the vitamin K group that are also found in green, leafy vegetables.
