I understand self-experimenting, I do it myself. I've tried Lugols and Colloidal Silver and Miracle-Mineral-Supplement and many supplements that didn't help and actually caused harm. And I'm upset with myself for listening to the people who promoted these things (and made money off of me as well).
But what really bothers me is when these substances are heavily promoted by Curezone members. In reality, none of us knows everything about how the body works and how it reacts to these substances over the long term.
What really bothers me is when people act like they "know it all" on subjects like Iodine and stridently try to convince everyone that Lugols will cure disease and will cause no harm. Again, I think this is unethical.
In essence, I think it's acceptable to experiment and potentially harm ourselves but not to try to convince others to do so, especially with products that have "poison" marked right on the label.
