What is Taheebo?

Tabebuia is a large genus of tropical trees that grows worldwide. According to one source, the correct name for the source species is T. impetiginosa; however, the majority of biological and chemical studies of the plant refer to T. avellaneda. The commercial product is derived from the inner bark. The tree grows widely throughout tropical South America, including Brazil, Paraguay, and northern Argentina. It has a hard, durable, and attractive wood that is extremely resistant to insect and fungal attack.
