Uh. Okay. If you'd like to know my "qualifications" to have an opinion on this, I'd be more than happy to provide them. I worked in medical diagnostics for years and am a huge fan of alternative medicine, I experiment in it all the time. I'm the guinea pig, so are a couple other people on occasion.
Hydroxyl radicals are very damaging, intense UV from the sun or tanning beds can also cause them, which is why tanning freaks get skin cancer. Anyways, I wasn't trying to be alarmist, I was just saying to use caution in overusing peroxide both internally and externally and there's good reason for that. I have absolutely no problem and am a big proponent of alt medicine that works. But the truth is that natural remedies can be very damaging if you don't know what you're doing. My mom has heart issues, and takes Coenzyme Q10, on my recommendation and it's actually helped with no side effects. I took it for a year before I recommended it to her after doing the research.
Read some of the following excerpts from studies on some of the bad effects of hydroxyl radicals:

The only reason I stated that it's "off the cuff" is that I haven't done a ton of research on using peroxide in the manners being recommended, but I do know a lot about the chemical properties and the potential dangers of introducing free radicals to the human body, inside and out.
Whatever will kill or mutate bacteria, will also kill or mutate our own cells, whether they be skin, stomach or any other type, this is why antibiotics can cause serious stomach problems. A bacterial cell is remarkably similar to many of our own cells and our cells are susceptible to the same problems that bacterial are. Peroxide kills many types of bacteria, and it should not be used with reckless abandon.
My caution stands, peroxide is not a miracle cure for all that ails you. If anything, vinegar is safer and used in a similar way as a cure-all, without the potential of free-radical damage.
There's no reason to be hostile, I'm using what I know to look out for the welfare of others, not just take a crap on the hope people may have in various types of cure-alls.
