Treat Colds
The common cold has no treatment, and hydrogen peroxide is no exception to the law. But there are ways by which common cold can be cured, and many people report that adding a few drops of hydrogen peroxide in your ears is one perfect way. Which can help to remove infections or obstructions in your ear.
Cold is seasonal but this H202 really works like an immediate solution where it helps in just reducing the irritation of the nose and just resulting in fewer sneezes.
Hydrogen peroxide has a vinegar-like smell that doctors have declared helps in immuning the body from cold or flu.
