Query: The Road to the Recycling Center

Paging through this book I bought back in 1999, I realize there are some significant outdated and proven unsuccessful treatments listed in here. I like to donate books I'm finished with to charity, but this one's going straight to the paper recycling center. That's how I will help to improve our toxic world. I couldn't in good conscience let this book out for someone to get a hold of potentially harmful and inaccurate medical information. I'm an advocate of naturally improving our immune systems, but some of the treatments here are unsafe. Other reviews of this book here have noted these dubious treatments, such as intravenous hydrogen peroxide injections, so I need not repeat. Please, just don't buy this book.
