The one and two star reviews are completely correct when they claim that this book contains a lot of self promotion and that the alleged five star, rave reviews appear to be fake. All but one of the 5 star reviews are written by persons who only review this book, only review books authored or co-authored by Ms. Fulghum, or are by "a reader" with no reviewer information whatsoever. Yes, the authors and publishers SHOULD be ashamed. The book should be able to stand on its own without infomercial-style "help."
I bought this at a book store, only after much internal debate. The book looked like a promotional waste. However, being desperate, I thought it worth the price if only I could get a little information from it. And that is exactly what happened.
As another reviewer has pointed out, much of the information contained is available on the web. I was also surprised that the authors (one of whom claims to be an expert in the field of otolarygology) would only suggest that people who irrigate their sinuses with saline might CHOOSE not to use iodized salt. All of the doctors, literature and web sites that I've encountered STRONGLY CAUTION patients to AVOID iodized, sea or kosher salts for irrigation.
That said, I will admit that there is useful information contained in this volume. Grossan's Hydropulse irrigation system, albeit overpriced, is the best method so far for nasal irrigation and is routinely recommended by other doctors. (It is, of course, quite possible that these others are simply parroting recommendations without real investigation. However, I'm pleased with it.)
The book correctly warns against purchasing nasal solutions with preservatives and discusses chiropractic and acupuncture. The latter two have offered me a measure, although not total, relief. I agree that stress, poor diet and lack of vitamins exacerbate sinusitis. I've yet to try the papain/bromelain enzyme lozenges recommended. Dr. Grossan's web site lists what it describes as a list of clinical trials and refers to published papers in medical journals. I'm going to look these up to see if they actually report positive results.
A definite turn-off is the infomercial style of writing. I'm always eager to read case histories, but, somehow, in this work they don't appear to be authentic. The writing style is often simplistic and has a "canned" feel.
Nevertheless, I'm giving it a 3 star rating for containing useful info, despite it's obvious and rather sleazy devices.
