HYDROGEN PEROXIDE AND IRON (well water) -- A BAD COMBINATION H2O2 and Distilled Water - No Problems Inflammation of the stomach mucosa has occurred in some cases where H2O2 was taken with well water, which is often high in iron. This combination produces Super Oxide Radicals, which can cause rapid breakdown of H2O2 in the stomach and irritate the G.I. tract. However, I have confirmed that when these same persons switch from well water to distilled water, they had no problems taking H2O2 orally. The enzyme, catalase, which controls H2O2, is in low supply in the stomach area, while plentiful elsewhere in the body. By using distilled water, little H2O2 breaks down in the stomach and most of it is absorbed into the blood. Should an ulcerated condition develop from using H2O2 orally, it can be reversed by stopping the oral use of hydrogen peroxide and eating a bland diet and taking herbs like whole leaf aloe vera juice and drinking cultured cabbage juice. However, this problem can be avoided by using distilled water which should not create any problems. Supplements containing iron and black strap molasses should not be taken for 1 hr before or after taking H2O2 orally. Vitamin C has also been implicated in the scheme above, so it is best to do this with distilled or deionized water only and forget the juices. Although I must mention one of the best ways to disguise the taste is with carbonated beverages like the sparkling fruit drinks. ECHO's admonition to only take three hours after eating is also sounder advice than the above for the obvious reason that the stomach will be emptier.
