Query: Beware

Before you take anything this "Doctor" says seriously, please Google him, read the Quackwatch articles about him. He is not a doctor. Several felonies, a long list of arrests and charges against him - all of these things tell me to beware. However, you can make up your own mind. Is this so-called doctor a sincere healer with multiple wonder cures for serious illnesses or the biggest scam artist and snake oil salesman to come down the pike in years? A well-meaning and trusted friend recommended one of his Hydrogen Peroxide/Oxygen products and this book to me. The treatment did nothing, so I looked this guy up on the Internet. What a shock to see his arrest record! You may want to do the same. Hey, maybe the FDA and FBI are in cahoots with the AMA, and are persecuting a beautiful human being. Or not. I'm just sayin'...
