"There is a case report in the medical literature of a 54-year-old man who, thinking it was iced tea, drank a "home preparation" of SSKI in water that his aunt kept in the refrigerator for her rheumatism. Over a short period of time he consumed 600 ml of this solution, which contained 15 gm of iodide, an amount 100,000 times more than the RDI. He developed swelling of the face, neck, and mouth, had transient cardiac arrhythmias and made an uneventful recovery."
The full text is in the link below. Good reading for those wishing to know more. 15mg of iodide is way out there - far beyond what one would normally take. I imagine chugging a couple bottles of mh's tinctures at once wouldn't be too good either.
