This book is in my opinion complete waste of money. The description of how immune system works is oversimplified and suitable for persons who have no previous knowledge of medical topics. The case histories described are truly frightening. Imagine a "holistic" doctor keeping someone (who is also diagnosed with chronic candidiasis) for eight months on intravenous antibiotics. The author gives alternative medicine a bad name. Most of the cases described are "chronic Lyme disease" which he somehow managed to diagnose in spite of negative tests. What a genius. He also likes to treat his patients with "oxidative therapy" i.e. intravenous hydrogen peroxide. Hydrogen peroxide must be very versatile substance, you can use it for established applications such as antiseptic or to bleach your hair, and according to Dr. Bock it can also cure anything from cancer to infections. Case study of cancer he presented regrettably died after her cancer spread everywhere, but she was feeling good which he counts as success. Another one of his favourite treatments is photooxydative therapy, where in addition to intravenous hydrogen peroxide he irradiates blood with UV radiation, if I remember correctly at 266 nm or so, which is supposed to "transfer energy to blood cells". Nothing is said about damage done to the blood cells in the process.
This creature should have his licence revoked. For the record, I have chronic health complaints and use herbal&nutritional medicine and have achieved releif of the symptoms, so this negative review is not a consequence of any prejudice towards alternative methods. As a physicist working on optical properties of organic compounds, I find his notions of "energy" laughable and erroneous, and I think his treatments can be highly dangerous. If you don't get any solution for your problem from conventional medicine, there are a number of alternative parctices which, unlike those described in this book, do no harm.
