DMSO (dimethyl sulfoxide) is a naturally derived solvent from wood pulp processing that has been used in integrative and alternative medicine for over 60 years for its extraordinary ability to penetrate biological membranes. DMSO carries therapeutic substances through the skin and into underlying tissues far more efficiently than conventional topical carriers, making it a valuable tool for delivering anti-inflammatory compounds, essential oils, and nutrients transdermally. Pharmaceutical-grade DMSO is used by veterinarians, physical therapists, and natural health practitioners for muscle and joint pain, bruising, nerve pain, and as a carrier for topical formulas. It has a proven safety record when used at appropriate concentrations and is backed by decades of published research on its therapeutic applications.
