Not just, but yeah... They use it on Race Horses. I have used it since 1993 on joints, but not too much down the hatch. I'm thoroughly convinced I walk today with no surgeries and can hyperextend my knee and be fine the next day thanks to using DMSO, and have only used it a few times in the last 30 years topically.Isnt DMSO just horse linament? I remember it being touted as a "cure all" back in the 80's. All it did for me was that it gave me garlic breath.
It has a laundry list of uses..
