DMSO is no longer used widely as it was before. I heard that DMSO can cause cataracts.
Before, if you had a muscle sprain etc. DMSO was a common solvent in trandermal pain killers, the entire football team here used it. But recently, some negative stuff has come out about DMSO (excessive use causing cataracts) so it is no longer widely used.
I was told this info by a pharmacist, i was skeptical at first... have you guys heard something similar?
