Thanks, that’s a load off my mind. It doesn’t really sound true but the bubbling action of peroxide always seemed a little ominous. Easy to see how this rumor started, it could be generations old.

Not sure if this is true but someone once told me that using hydrogen peroxide on wounds of a certain size might lead to a bubble of gas appearing in the bloodstream, which would be undesirable. I dunno, I rinse my mouth with diluted h2o2 occasionally and might put it on a small scrape but I’m a little leery after hearing that. Also the “cauterizing” effect seems like it might slow healing or cause a more notable scar.
