No one understands all of the things that Iodine does. I made the observation a long time ago that x% of people were having serious problems and tried to warn the cult, but was censored.
Finally now it's in print and forumized.
I'm not sure whether to tip my hat to V for being menschy and officialamizing the phenomenon or whether he was being crafty and shooing away all the pesky people who presented problems.
One thing to keep in mind is that Iodine is a very strong multi purpose anti-pathogen bomb. It seems to kill all types of pathogens. It's even been used to treat malaria.
