Pau D'Arco is made from a tree native to the Amazon rainforest. This splendid tree carries gorgeous purple flowers in the spring, and these flowers keep the tree immune from disease, parasite and fungal attack. The local indian name for the tree is “TAJY” which means “to have strength and vigour”. The active ingredients are sourced from the inner bark and are said to have the same effectiveness. To enhance the effects, the Rio Pau D'Arco vegicaps are made from a 5:1 extract and the Tea bags are at supplement strength.
