Lapacho, also called pau darco, ipe roxo, taheebo or tahuari, is the name of a tree that grows in the tropical forests of Central and South America. The inner layer of its bark is dried and used to make a drink called lapacho or Inca tea. Pau darco is traditionally used by the Indians of Latin America. In Europe, it is used in dietary supplements because of its health-promoting properties that are still being discovered. Lapacho is, above all, a natural way of supporting the bodys physiological immunity. In addition, this plant contributes to relaxation and mental and physical well-being. Pau darco is also traditionally used as an herb that supports proper circulation and blood pressure. It helps maintain the health of blood vessel walls and capillary microcirculation.
