Does hydrogen peroxide do more damage than help as a disinfectant?

Question

I heard from some people that it isn't advisable to use hydrogen peroxide in large amounts 'cause it kills/ damages the live tissues... is this true?.. please put a reference for your answer...

Answer 1

Hydrogen peroxide is one of the best antiseptics available.  It is effective in concentrations of 2-4%, while still safe for non-medical use on humans at much higher concentrations (for example, peroxide hair bleach is typically 15% hydrogen peroxide).  It is true that hydrogen peroxide can be dangerous, but the danger involves intentional misuse of the product or concentrations not available to you.

Answer 2

You do not apply any disinfectant to live tissues, if they kill bacteria then they also will kill human cells as well.

Disinfectants are applied to inanimate objects, antiseptics to

intact skin (preoperatively) or healing skin.

Hydrogen peroxide(3%) is good to apply on a healing wound, the catalase enzyme makes Oxygen gas bubbles that not only clean the wound but also are toxic to some bacteria.

Hydrogen peroxide is weak at killing bacteria, those sensitive to oxygen are the most affected, it is so weak I have doubts it would hurt human cells, but there are no specific statements I can find that make that claim.

Antiseptics are not really that well researched, they came along a little before the sulfa drugs and antibiotics so researchers dropped antiseptic study when the more exciting and profitable internally used drugs appeared.

Rule of thumb: if what ever you apply as an antiseptic causes pain that is the body telling you that damage is being done, so stop it.
