Ingestion of high-concentration peroxide as promoted in some alternative medicine circles poses numerous life-threatening issues. Investigators examined ten years of poison control records regarding high-concentration peroxide ingestion (10% or greater concentration) and found that nearly 14% of reported cases had an embolic event and 6.8% died or exhibited continued disability. Study author Dr. Benjamin Hatten writes, “This is a caustic liquid, and as with many poison prevention efforts, we recommend keeping this product in its original container and adding both child-resistant capping and a colorizing agent to reduce the possibility of accidental ingestion.”
