I bought two books by F. Cambayrac, being myself suffering from a seriously debilitating form of chronic fatigue every day, for over ten years. His first book, focused on heavy metal poisoning, with a host of scientific references, is very interesting indeed indispensable. This second book focuses on evidence and the "way out", is much more debatable. If I do not question the published evidence, I challenge the other hand the fact that it has held that the evidence in favor of the method of detoxifying it advocates: that of injecting intravenous chelation. But the testimonies of people who have not been improved by this method are many, including France; just search a bit (specialized forums, assos ...), contacting people ... and this method of detoxification is very expensive! Worse, people have even seen their condition deteriorate following treatment undertaken under the guidance of Mrs. Cambayrac. I read a number, certainly it is a minority, but still, you have no right to ignore this. Personally, I made 5 injections of chelating with a physician on the "list" Ms. Cambayrac. The 5th will be the last because my condition has deteriorated significantly since (heart palpitations, insomnia, increased fatigue ...). Yet the protocol was followed to the letter. The author is not a physician, nor scientific, and on a topic still poorly known where knowledge is changing regularly, it should have been content to recount his testimony, and avoid getting up as undisputed expert on the subject. Especially since there are other methods of detox, including that of the American Cutler has proven, which is less risky and less expensive. We easily enthusiasm for a book on health, especially when one is oneself sick, but it's the concrete result which not account? And I have nothing to sell me. Just a testimony to give, to prevent others to do the same mistakes.
