Query: Hydrogen Peroxide: Medical Miracle

There is probably not too much wrong with this book, Hydrogen Peroxide: Medical Miracle, but it is at least 10 years old so much of the material is outdated, and in some instances regarding oral consumption of Hydrogen Peroxide it is contrary to the present direction that the industry is taking. A recent book I read states that only Food Grade H2O2 should be used whereas this book gives advice that 3% can be used orally. If you have a more recent publication, I would like to be advised.
