Dr. Tilden began to question the philosophy that the use of medicine was the only real cure for disease. His extensive reading, especially of medical studies from European medical schools, and his own thinking, led him to the conclusion that we build disease from within. His thoughts on toxemia began to formulate and materially develop. Using no medicines he practiced his theory of clearing the body of toxic poison and then allowing nature to make the cure. He taught his patients how to live so as not to create a toxic condition and to retain a healthy body free of disease. Toxicity Explained is Dr. Tilden’s manual for a healthy life.
