Mr. Griffin marshals the evidence that cancer is a deficiency disease like scurvy or pellagra aggravated by the lack of an essential food compound in modem mans diet. That substance is vitamin B17. In its purified form developed for cancer therapy, it is known as Laetrile. Why has orthodox medicine waged war against this non drug approach? The author contends that the answer is to be found, not in science, but in politics and is based upon the hidden economic and power agenda of those who dominate the medical establishment. This is a new edition of the book. It is the most complete and authoritative treatise ever produced on Laetrile. It explains the theory by which Laetrile is believed to work. Case histories are included.
