As a rainforest canopy tree, Pau d’Arco requires tropical growing conditions consistent with its native habitat in South America. The tree is evergreen and reaches substantial size as a canopy specimen.
The medicinal bark is harvested from mature trees, and sustainability concerns have arisen due to over-harvesting in natural rainforest habitats [A-5]. The medicinal component is the inner bark lining, which is harvested by carefully stripping bark from the tree without girdling and killing it [A-1].
Propagation occurs through seeds, and the tree requires full sunlight for optimal growth.
The bark is typically dried and can be stored in airtight containers away from direct light and moisture for extended periods.
Pau d’Arco is most commonly prepared as a tea by simmering the inner bark in water. It can also be used topically as a wash for skin infections and wounds [A-2]. For internal use, the tea has been suggested for testing against cancer and for addressing a wide range of infectious conditions [A-2].
