Fluoride is a proven toxin. Its effects are widely known through clinical study.
Clinical study has also shown Lugol's solution to be effective, safe, and a curative for many things, particularly FBD and fluoride toxicity.
I don't want to get into a pissing match here. I will simply say my wife & I have taken Iodoral (lugol's in pill form) for over 6 weeks and have both seen marked improvement in our condition. I have seen great improvement in my liver & eliminatory function. My wife has seen a marked decline in migraines and a skin condition clear. Poison doesn't do that. Lugol's has been used over 200 years with more success stories than one could count.
If you like tree iodine and it works, use that. If you like Lugol's like us, use that. One thing I and doctors who have tested Lugol's can tell you abundantly is it is not a poison. Far from it.
MH encourages people to think for themselves and experiment. Good advice indeed.
