DMSO has the unusual ability to depress the freezing point of water dramatically, while maintaining viability with many cell and tissue types. It is a sulfur-containing organic compound that is derived from MSM, and can be used internally or externally. 

DMSO is widely used as a topical analgesic and anti-inflammatory, and is a known antioxidant. It can quickly penetrate the skin and other membranes without damaging them. 

DMSO's powerful ability to dissolve and carry anything with which it is mixed into the muscles, ligaments and blood can be an advantage when one wants to carry drugs or herbal extracts into the body through the skin.

DMSO exhibited zero-order degradation kinetics when sufficient ozone was supplied. It is an effective pain killer, blocking nerve conduction fibers that produce pain.
