Skye Weintraub has definitely put together a great book. At first when she's identifying each parasite, she tells you the "conventional" way of treating each one--which upset me because she's an N.D. But I suppose the pharmaceuticals must be listed as well. Thankfully, later in the book she gives prevention advice as well as herbal remedies. I've learned a lot just researching the internet, but this book taught me even more. I am very glad I bought this book. I started treating myself before I got a hold of this and I wish I had read this first. I've made several mistakes, but hey--I'm still alive! Parasites-and getting rid of them-can be very dangerous. The problem is much more wide-spread than people realize. All these people with unspecified problems (fibromyalgia, CFS, IBS, colitis, etc.) would do well to purchase this book and find out the REAL cause of their ailments. I have been misdiagnosed for years and finally I had to diagnos and treat myself (obviously without using those horrible pharmaceutical drugs). I almost died because of parasites (don't know which ones) and the treatment. It is highly advised to find a good alternative care doctor (one that doesn't use drugs or surgery) before embarking on a cleanse, if in fact you are heavily infested as I am. As far as the reviewer who asked "where's the facts"--the book is not riddled with footnotes (which I appreciate). However, if you look in the back, Skye lists the books that she has used as reference. The only problem I have with the book is the fact that she recommends Grapefruit Seed Extract as a useful antimicrobial. Commercial GSE has been shown to contain methylparabens, triclosan, and benzethonium chloride. These chemicals make the GSE antimicrobial. DO NOT use commercially prepared GSE!!! In Dr. Weintraub's defense, the book was published (in 2000) about the same time as the study by von Woedtke (1999) which showed what the extract really contains; and before the study in 2001 by Gary Takeoka and his group, which confirmed the findings. If these studies were available to her, I don't think she would have recommended the use of GSE in her book. Thankfully, I am intelligent enough to do tons of research, not just trusting one book or source. All in all: a very good book, priced just right, and VERY much worth buying!!
