This belongs in the debate forum, but I have one thing to say.
I have not ever heard of one person dying of an overdose of iodine. I'm sure there are some (and I'm sure if one did, someone would be in here with the obit), but you'd think that people in Japan would be dropping like flies, wouldn't you?
Yet people keep getting well. You know, people in the herbal parasite forum think all of us who take drugs for parasites are insane and will surely die, but those drugs are the only things that are keeping me alive to fight another day.
Then there's that thing about water killing you if you drink too much.
