The medical miracle of H202 is a good straightforward book with information and examples of the medical uses of H202. The good news is William Campbell Douglass is an MD. He shows the uses and misuses of the application of hydrogen peroxide. This is not written like promotional information for the product, which is a good thing. It is simple, dry and humorous at times, which is good for this type of book with health industry jargon. The only bad news is that it would of been nice to see more examples of how the everyday person could find safe uses for the product in there own home, since most of us are not medical practitioners. Don't get me wrong, there are a few good examples of practical uses (including using it as a mouth-wash, toothpaste or to snort as a sinus cleanser), but if you think he is going to recommend using it orally, he won't. Overall, good book, I learnt what I was looking for in obtaining this book, thus I consider it a worthy purchase.
