What is Pau D'arco Used for?

The bark of the tree is used in traditional medicine and usually prepared as a tea. It is used as a blood alterative, to support immune function, to support a normal inflammatory response in the body and topically for skin conditions as well as promoting a naturally healthy microbial balance of the intestinal tract. Modern research has focused on a group of alkaloid constituents referred to collectively as Lapachols. Surely the tannin content and entire activity of the bark contributes to the activity.
