Hi,
Pau d'arco also known as Taheebo is the inner lining of a tree found in South America and some parts of Europe, it has been used as a Cancer cure for Generations and its use has been traced back to the ancient Incas, Egyptions and Vikings...It is a main course of treatment in South American Hospitals for Cancer.
There is lots of information to read and if you so desire high quality tea available at www.herb-care.com.
Thanks
