This book by the ingenious physician and pioneer of a scientifically based natural medicine Maximilian Bircher-Benner, known all over the world for his famous recipe called "Birchermuesli", is still highly relevant. In his clinic, he has treated thousands of people from around the world to heal their chronic ailments considered incurable. It demonstrates the biographical path from a well-trained physician to a "new physician" who in everyday practice has recognized a totally new holistic view of a person, their biology and their soul. This is an ingenious point of view which leads the way out of the trap in which our medical world and health system find themselves today.
