Life Choice DMSO Gel - A sulfur-containing organic compound that is derived from MSM, and can be used internally or externally. DMSO can aid injuries such as sprained ankles, sore muscles and joints, and even fractures. The process starts when DMSO enters the bloodstream by osmosis through capillary walls. Then, DMSO is distributed throughout the circulatory system. Historically, DMSO has also helped conditions such as neurological damage, arthritis, back problems, keloids, acne, burns, musculoskeletal problems, sinusitis, headaches, skin ulcers, herpes, and cataracts.
