Pau d'arco or Taheebo tea as it is sometimes called is the inner lining of a tree found South America. It has been used as far back as the ancient Incas and Aztecs and there has even been evidence found supporting its use by Vikings. It is used for many other ailments besides Cancer with great success.
Lapacho (Pau d'arco, it has several different names depending on the tribe and region it comes from) is applied externally and internally for the treatment of fevers, infections, colds, flu, syphilis, cancer, respiratory problems, skin ulcerations and boils, dysentery, gastro-intestinal problems of all kinds, debilitating conditions such as Arthritis and prostatitis, and circulation disturbances., Other conditions have reportedly been cured with lapacho including lupus, diabetes, Hodgkins disease, osteomyelitis, Parkinson's disease, and psoriasis.
It is used to relieve pain, kill germs, increase the flow of urine, and even as an antidote to poisons. Its use in many ways parallels that of the immuno-stimulants echinacea on this continent and ginseng in Asia, except that its action appears to exceed them both in terms of its potential as a cancer treatment. The Guarani, Tupi and other tribes called the lapacho tree "Tajy," meaning "to have strength and vigor," or simply, "The Divine Tree."
It truly is an amazing botanical/herbal, and is now being studied and used in trials in South Africa for the treatment of Aids patients.
