Rudolf Breuss, a natural healer, was a most extraordinary man who devoted his long life to helping people. Born in 1899 into an impoverished Austrian family, he had a desire to help at a very early age. His eager young mind absorbed every snippet of knowledge he could lay his hands on. He educated himself by reading books and attending lectures whenever he could - a practise he maintained throughout his life. Today Breuss' legacy lives on in the form of his book that has sold over a million copies world-wide. I have included his kidney tea blend because of the great respect for the work of this man.
