Tabebuia, commonly called taheebo or pau d'arco, is a genus of tropical plants native to the rainforests of Central and Southern America. It has traditionally been used as a folk medicine to treat infections, cancer, blood coagulation, immune problems, inflammatory diseases, and peptic ulcers. High-quality studies on the use of pau d'arco for any condition in humans are currently lacking.
