According to the American Cancer Society, 35 percent food-grade hydrogen peroxide is commonly used to wash and preserve produce and to disinfect surfaces, tools and machines used for food preparation. These are two of the few uses approved by the U.S. Food and Drug Administration. One specific brand of high-strength hydrogen peroxide, 35% PEROX-AID, is approved by the FDA to control mortality rates in several aquaculture species for veterinary care.
The FDA released a statement in 2006 warning general members of the public against using food-grade hydrogen peroxide internally, as it is highly corrosive. The FDA also does not support the use of diluted high-strength hydrogen peroxide for any medical treatments touted by alternative health advocates.
Some popular claims are that the solution can treat parasitic infections, cancer, diabetes, herpes, hepatitis, gangrene, high cholesterol and Alzheimer's. Additional conditions claimed to be treatable by the solution include leukemia, anemia, lupus, Parkinson's, arthritis, acquired immunodeficiency syndrome (AIDS) and eczema. The FDA asserts that none of these conditions can be assessed or self-diagnosed without the intervention of a professional medical practitioner.
Furthermore, ingesting 35 percent food-grade hydrogen peroxide can cause ulcers and other forms of gastrointestinal irritation. In the most severe cases, it can lead to death. Administering the solution intravenously can create dangerous oxygenated bubbles in blood vessels or induce extremely dangerous allergic reactions.
