Hydrogen peroxide (H2O2) has been used for decades as a household disinfectant and natural remedy. On Earth Clinic, readers have long reported using hydrogen peroxide—both externally and internally—for infections, sinus issues, oral health, skin conditions, detoxification, fungal concerns, and respiratory support.
