Hey Cougar- yes, there have been cautions against Iodine in a nebulizer/inhaling Iodine vapors. I do not know how much would be a good amount to try, the ratio that you suggest sounds safe to me...
And TY:)
Iodine, bring back the Universal Medicine!
And, looking forward to your report~!
I DO know that there are lots of posts on "inhaling" Iodine here, including more historical stuff~
