Review of Jerzy Zięba's book ‘What your doctor won't tell you’ Part III A few years ago, I received as a gift from a doctor friend (she didn't have time to read nonsense, and I was interested in the subject) Part I of Hidden Therapies. I thought, another haunted author. As I started reading, my attitudes changed until the one I have today. Someone who is not professionally involved in medicine writes about things that are so obvious to me that my esteemed colleagues cannot understand. He is not writing about a recipe for curing diseases, he is dealing with the cause of the disease.
