The inner bark of Tabebuia impetiginosa is used medicinally. It is dried, shredded, and then boiled, making a bitter brownish-colored tea known as Lapacho or Taheebo. The unpleasant taste of the extract is lessened when taken in pill form, or as tinctures. Lapacho bark is typically used during flu and cold season and for easing smoker's cough. It apparently works by promoting the lungs to expectorate and free deeply embedded mucus and contaminates during the first three to ten days of treatment.
