DMSO (dimethyl sulfoxide) is a colorless, slightly oily liquid that is primarily used as an industrial solvent. DMSO is derived from from lignin, the binding substance of tree, as a manufacturing by-product from the processing of paper.
In 1963, a research team headed by Stanley W. Jacob, MD, at the University of Oregon Medical School discovered DMSO's powerful transdermal properties (meaning it can carry anything that touches it through the skin and into the body) and its analgesic and anti-inflammatory affects.
As a topical analgesic, DMSO appears to reduce pain by inhibiting transmission of pain messages by nerves and may also soften the abnormal connective tissue.
DMSO (dimethyl sulfoxide) is available as a liquid and as a cream.
