Hi Ragweed - thank you for pulling up those articles. The potential for harm is high and there is no peer-reviewed scientific evidence that it is effective.

Welcome @ragweed. Hydrogen peroxide is used by some dentists as a mouthwash/gargle but it is diluted and spit out (not swallowed).

Yes, my dentist recommended this: three parts water and one part hydrogen peroxide. I declined this and went for the commercially prepared antiseptic he was offering.

A quick search found a few documented cases where harm has been established from huffing H2O2. Here's one of them;

The naturopaths that push nebulizing H2O2 tend to recommend a diluted (.5%) solution, which seems relatively safe. But the potential for misuse exists. The toxicity of H2O2 at higher concentrations has been established;

Hi @Blard,

Hydrogen peroxide is considered toxic by the Agency For Toxic Substances And Disease Registry: learn more here.

It is a known irritant to the eyes, nose, respiratory airways, and skin. It can be toxic if ingested, inhaled, or by contact with the skin or eyes. Here is a journal article on hydrogen peroxide poisoning.

Hope this helps!

Being forced to inhale dog dander in public businesses and stores is dangerous, too, but we are still waiting for a disclaimer like this. If a person chooses to inhale hydrogen peroxide, they are making a personal decision for themselves only and are accepting all personal risks. However, asthmatics and people with allergies are being forced against our wills to inhale dog dander, and while we understand the life-threatening risks, we don't have a choice. Please create a graphic for that, as well.

Thank you but very little information (none) is given here to substantiate the level of harmfulness, along with other articles that I have read that are about a sentence long claiming this “unstable” molecule can damage cells and dna. Except, hydrogen peroxide is used for injuries (in lacerations in which it can enter the bloodstream) and for gargling where it enters the mouth and sometimes the stomach. If causes such damage to the dna, it should probably not be used for gargling either. So only lung cells it harms and the evidence of this?? I am reading studies where a small portion of subjects are given inhalation treatment and nowhere did it mention harm.

Welcome @ragweed. Hydrogen peroxide is used by some dentists as a mouthwash/gargle but it is diluted and spit out (not swallowed).

When the covid first hit last year, an old friend told me she nebulizes H2O2 whenever she's exposed to crowds. She is anti-mask & anti-vax. I researched it a bit and found Dr Mercola (a popular internet alt-med "doctor" who markets all kinds of alt-med products and disperses covid disinformation) was advocating this. He's probably selling nebulizers / "food grade" H2O2. An immediate RED flag. I will say my dentist has me gargle with diluted H2O2 before checking my teeth and gums, so it must have some antiviral properties, but I surely won't be inhaling H2O2 mist.

My God, who does this? Thank you for this public safety alert!
