Pau d’arco comes from the bark of trees grown in South American rainforests. Its name is translated to “bow tree” from Portuguese, as the trees have been used to make bows and arrows. Its bark has been used throughout history, including being boiled down into tea. We source Nature’s Way Pau d’Arco where it grows best and use three levels of testing methods to make sure it meets our high-quality standards.
