Prof. Arnold Ehret is one of the most revolutionary thinkers and health practitioners in human history. Some of his ideas are formulated so brilliantly that they will still be relevant in 500 years. They are simply timeless, as they show humanity the way out of the dead end of diseases. Ehret healed himself from a then incurable and fatal illness in 1900 through fasting and dietary changes. Today, modern medicine would perform dialysis and a kidney transplant in such a case. After his complete recovery, he helped thousands of people in their healing journeys and gave many lectures, including in the USA. We have made it our mission to republish all of his articles and books, as they are among the most valuable texts in human history. Contents of Volume 1: 1. "Questions of Life," 2. "Sick People.".
