DMSO has been used for over 100 years in the United States. It is a natural substance derived from wood pulp and is harmless when used with the proper precautions. It is sold as a solvent. DMSO is an amazing substance that has many uses throughout the world.

Dimethyl Sulfoxide is a clear liquid known for its ability to permeate living tissue. It is believed to help stimulate cellular processes. It has a distinctive and slightly unpleasant odor, but Dr. Morton Walker, in his book, DMSO: The New Healing Power, describes how it appears to help block pain, reduce inflammation, kill bacteria and funguses, reduce blood clotting, improve circulation, neutralize free radicals, stimulate the immune system, and hasten the healing of wounds. The face and neck are more sensitive to topical DMSO than other parts of the body, and the maximum concentration of DMSO should therefore be reduced by diluting the concentrate with sterile or distilled water. If you develop a rash or redness, you may want to reconsider using this product.
