Dimethyl sulfoxide is a great cure for inflammation of all sorts. Used it for years. I too had a horse trainer source. LOL. It is a controlled substance in Canada so be careful at border points. I thought the FDA blacklisted it so you probably need a horse source to get it. I don't know. Safe and cheap to produce clean so it is like Fish Antibiotics Same for them same for us. I can't read Russian well enough to know if what I am buying here is the right antibiotic, You can buy over the counter and I was going to do that and saw a fish store. Went in and sure enough English spelling on European produced antibiotics for aquarium creatures. Read they were the same as human concoctions so four bucks later I was stocked. Worked like a charm!
One very important thing is it takes things into the bloodstream, will dissolve cheap Nitrile gloves. And take that into you. Morphine, LSD, and a few other drugs have been added by not so nice people in the past to dose someone without them being aware. Little sponge under the car door trick, used by some intelligence agencies. You never notice you got dosed and then while you're driving "purple Haze time."
A great use for pain and sprains. Just be really careful what is on your skin or hands before application.
Ultrasonic cleaners are awesome too. Gout pain in the big toe? Place it in an ultrasonic cleaning bath for ten minutes and gone. Destroys the little crystals too so it doesn't come back. Had an outbreak here, too much beer, and our medic found a gun store. They have big ones for cleaning weapons. Horrible pain gone in ten minutes, cured no further issues and it has been three months. No beer since.
