Dimethyl sulfoxide (DMSO) is an organosulfur compound with the formula (CH3)2SO. It can uniquely provide solubility to certain very polar small molecules, such as simple biomolecules with multiple protic functional groups.

DMSO is generally used as a solvent. It can be used as a topical application to reduce acute swelling due to trauma. It is a natural product from trees that relieves muscle and joint pain, treats bladder inflammation and protects healthy cells from cancer and chemotherapy drugs. 

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. 

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 helps to reduce the swelling, which is a result of inflammation of tissues and cartilages that have been injured. It go directly in to the blood stream, making it an effective transdermal. https://dmso.com.au/
