It is important to know what this book is, which unfortunately the official "book description" does not state.
Pages 1-21 are copies of letters that the author F. Batmanghelidj M.D. wrote to various doctors, Universities, medical organizations, etc. They are emphatic statements informing these groups about the author's documented cases of illness reversal using only clean drinking water and sea salt. These letters are very passionate and direct.
Pages 23-30 contain short descriptions of the 15 most common illnesses/diseases that have chronic dehydration at their root. The information presented in broad-scoped, written for the layperson and lacks detailed science.
Pages 31-217 are letters written by people who have applied F. Batmanghelidj's water cure protocol and have healed their serious health problems. The heading to each letter states, in bold, the health conditions that were positively affected.
Pages 218-226 are supplementary material, such as the About the Author section, index and other resources.
If are looking for how and why the water cure works, this is not the correct book. Read Your Body's Many Cries for Water, the author's original book on the subject. Water Cures: Drugs Kill presents people's accounts of how the water cure worked when other medical approaches did not. As inferred in the author's opening pages, this book is intended to present real-world evidence that chronic dehydration is a world-wide epidemic that can be solved very simply and cheaply - much to the chagrin of the medical establishment and pharmaceutical companies.
Why did the "water doctor" write this book? I feel that he needed to prove to the world that drinking water can save so much unnecessary suffering and disease. Because the medical establishment would not promote or use his medical science because virtually no money can be made.
My theory is that once the world's clean water is minimal, then we'll see the bottled water companies (Coca-cola, Pepsi, Nestle, etc) start advertising water as a miracle health cure. Blue Gold: World Water Wars
