  • Tabebuia, commonly called taheebo or pau d'arco, is a genus of tropical plants native to the rainforests of Central and Southern America. Several Tabebuia species are currently threatened, vulnerable, or endangered due to logging and expanding agriculture.
  • The indigenous peoples of the South American rainforest have used pau d'arco medicinally for hundreds of years. The traditional use of pau d'arco may predate the Incan civilization.
  • Pau d'arco has traditionally been used as a folk medicine to treat bacterial infections, cancer, blood coagulation, inflammatory diseases, and peptic ulcers. The bark of Brazilian Tabebuia is most commonly used for yeast infections, viral infections (flu), immune problems, and cancer.
