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

DMSO is a potent antioxidant, scavenging the highly reactive molecules that contribute to disease and aging, known as free radicals. It  is used as a topical analgesic to block pain signals.
