as a dry eye sufferer this is interesting, although not something I can do at home......the iontophoresis part that is.
but this is great that it gives a reasonable Iodide concentration to try in drops
0.5% Iodide solution
as we know here iodine/iodide seems to make anything that secretes secrete better. I don't know quite why, but I find that idea really fascinating. Maybe because it speaks to the idea that basic cell and/or organ structure is basically similar with modifications. Mammary glands are a modified sweat gland and they both need Iodine to secrete.
And what are we without secretions.....pretty boring in my book!!!!
that makes me think of the movie Demolition Man.....
