Is this pharmaceutical grade? my jar specifically states it is to be used as a solvent!

DMSO is not approved for humans because it can possibly penetrate the human blood brain barrier. That being said I’ve used it for YEARS on horses and it’s been past around and shows and rodeos for riders even longer. I’ve used it on myself the whole time off and on for sore muscles and pain.

Why is this fragrance-free version 50% more expensive than the rose scent version?

Actually the rose sented version is more expensive only 4oz jars sells for just over 20$. This is a 16oz jar for only 28$.

What body parts can u use smso

DMSO is a polar aprotic solvent. It is chemical name - Dimethyl-sulfoxide. Use it with caution. If you are allergic to sulfa- or sulfur, try small amount on your inner part of the elbow and see if there is no reaction on your skin after 24 hours. It can cause contaminants, toxins and medicines to be absorbed through the skin, which may cause unexpected effects. It may increases the effects of blood thinner, steroids, heart medicine, sedatives etc. It could be harmful or dangerous. It is a developmental neurotoxin. I would not use it on open or not settled scars/wounds. But is used topically to decrease pain and speed the healing of wounds, burns, muscle and skeletal injuries. DMSO also is used topically to treat painful conditions such as headache, inflammation, osteoarthritis, rheumatoid arthritis and severe facial pain called tic douloureux. It helps with pain: lower back, back and spine, shoulders, knees, legs, hands, arms... Use small amounts and wear gloves when apply. Some people reported diarrhea, when used on a lower back. It is used to treat cancer. It is widely used in veterinary for injuries on horses and dogs
