I am sorry, I don't know that much about Iodine to tell you anything about it. If you want to know more, I think there might be a forum here on curezone that you can find the information that you are looking for. I just heard one person say that the iodine attaches itself to things and they can't escape from it. I don't know if that statement is true or not, like I said before, I don't know that much about iodine. I have not gotten into that research yet. I tried it and it worked for me but everyone is different. That is all that I can tell you. Have fun researching it! Hey, if you do find out something let me know okay? Donna
