Tabebuia impetiginosa is a towering deciduous tree native to tropical regions of the Americas. Pau d’arco is used for its inner bark, referred to as “taheebo” or “lapacho”. This tree bark has been employed for thousands of years in the traditional healing practices of native tribes throughout these regions, including the Incas who also made bows out of the tree. (2)
Pau D’arco is made from the inner bark of several species
of Tabebuia trees that grow in Central and South America. (3)
Ascorbic acid, chromium, iodine, magnesium, manganese, phosphorous, selenium, silicon, zinc, napthaquinones, flavonoids, carnosol, lapachenole, indoles, alkaloids, coenzyme Q10, steroidal saponins. (4)
Several compounds called naphthoquinones — mainly lapachol and beta-lapachone — have been isolated from this inner bark and are thought responsible for its purported benefits.
Pau D’arco is native to South and Central America (specifically Brazil). It is not native to North America but grows in the warm parts of the country. Pau D’arco is derived from the inner bark of several species of Tabebuia trees. (5)
The tree grows up to 125 feet high, has purple, pink, and yellow flowers, and pod-like fruits. The best quality Pau D'Arco is said to come from Argentina. The most potent part is the inner bark, which must be aged after harvesting to maximize its effectiveness. (5)
