Can you post the website regarding that? I've never heard of that before. I've done a lot of reading about H202 and it seems that the only negative comments about it are from the vested interests like the Pharmaceutical Companies and the American Cancer Society. If you heal yourself with Hydrogen Peroxide then they lose money so can you really trust them? However if there are any non biased medical studies proving the negative side effects of H202 I would like to read about it. The problem is no one will spend money to research this because it cannot be patented.
