We used to use it on horses when I was younger, but like MG said, it's a chemical we use in the lab. It has a very distinctive odor and can burn your skin if you use too much. I pulled up the following information from an on-line MSDS:<br><br><br>
General: DMSO has shown very few toxic symptoms in humans. The most common are nausea, skin rashes and an unusual garlic-onion-oyster smell on body and breath.<br>
Inhalation: High vapor concentrations may cause headache, dizziness, and sedation.<br>
Eyes: Low hazard for usual industrial/ commercial handling by trained personnel.<br>
Skin: Stinging and burning of the skin as well as rashes and vesicles have been seen. A heat reaction may occur if applied to wet skin. Avoid contact with DMSO solutions containing toxic material or materials whose toxicological properties are not known. DMSO easily penetrates the skin and may enhance the rate of skin absorption of skin-permeable substances. But because of DMSO’s low toxicity and its inability to carry less-permeable substances with it through the skin, it can be concluded that DMSO does not pose a significant threat by skin absorption.<br>
Ingestion: A low ingestion hazard.<br>
