Pau D'Arco (Tabebuia impetiginosa) is a hardy, deciduous tree that is able to withstand severe winds and weather. Pau D'Arco trees are found extensively throughout South America, Central America, Mexico and the Bahamas where it is frequently known as "Taheebo". The herb is harvested by peeling the bark from the tree in vertical strips from the ground up to the height of a man. Only the inner bark is used for beneficial purposes and must be carefully separate from the outer bark. Its purple inner bark was used by the Incas, who referred to it as "The Divine Tree". It has enjoyed renewed interest throughout the world for its beneficial properties. For more than 75 years, long before it became fashionable, Alvita was championing the profound health-giving properties of herbal teas. We travel to the far reaches of the globe for the finest herbs, the best growers, the most precious sources. Small wonder that so many consumers trust the Alvita name.
