I once had an MD in the Chicago area give me a four hour drip IV of pure DMSO.
It did me no harm. I was told by the nurse that it would make me stink so bad that if I were to take a bus home everyone else would probably get off the bus.
As it turned out my wife banished me to sleep on the couch for the next three nights.
So my only warning about DMSO are that you may offend other around you.
DMSO is often used for trans dermal drug delivery, but the method may be to wash the skin with it prior to applying the drug, rather than mixing the drug with the DMSO... not sure...
A question I have is since DMSO was primarily originally used as a strong industrial solvent, will it alter or destroy the Miracle-Mineral-Supplement ?
