today i had a dialogue with someone i really respect at my local natural store. he told me that h2o2 does have the ability to kill pathogens in the body, but as the same time, to use it internally is probably not a great idea, as it is corrosive, even diluted.
i've heard of putting it in your ears when cold or flu is present, where it can get close to the eustacian tubes, and kill stuff in there. that sounds better to me.
the respectable guy also told me that grapefruit seed extract will accomplish almost the same thing as h2o2, and it won't corrode your insides! i've started on mega doses of g.s.e.
