This text is intended for both the lay person & the physician, & is also appropriate as a medical school text book. The author proposes that it borders on malpractice to treat depression as a Prozac deficiency, to drug cardiology patients, or any other medical/psychiatric problem without first ruling out proven correctable causes. With over a thousand complete references it covers the causes of leaky gut syndrome, intestinal dysbiosis, hormone deficiencies, hidden sensitivities to food, mold, & chemicals as well as dysfunctional detoxication, heavy metal & pesticide poisoning, xenobiotic accumulations, & much, much more. It is the best blue-print for it explicitly spells out what tests to have, what to take to correct each condition & what nutrients to take. If no one knows what is wrong with you, you need this book. If they know but say there is no cure, you need this book. If they say you need medications to control your symptoms indefinitely, you need this book. It is inconceivable that there is anyone who would not benefit from this book as it leaves drug-orientated medicine in the dust of the 20th century. & it does so by using the only disease that by definition sports a lack of hope. This disease, depression, was chosen as a prototype to drive home the message that just when you least expect it, there is always hope.
