I am looking at the bottle right now that I purchased at a health food store in Spokane, WA. It says "FOOD GRADE HYDROGEN PEROXIDE 35%". I have had this bottle for three years now, and when I bought it the only thing the store owner said she could say about it was that it was not meant for internal use (but she was legally obligated to say that). The product is called Azur Standard made in Dufur, Oregon. I have just used it as a cleaning agent, but my husband has taken it internally.
What is bad about it if ingested in a diluted form?
