"As for internal use, none will be for internal use so you can ignore that altogether."
I disagree here! I have found many sources in which the iodine is ingestible.Crows is ingestible.I have also found many other forms of Iodine that are for Lab use only and therefore not safe for human consumption. Here you can see that it clearly states that this iodine is ingestible and safe under 4 drops.http://jcrows.com/lugolsmsds.html
