I Purchased some DMSO at a feed store (USA) and have been mixing it with CS for topical application. The CS is around 50 PPM on my meter (which I see from some mail might be subject to question) I have been applying it to my knee's once a day (I have arthritis in them) for about 10 days . After 2 days I was able to stop taking my pain medication (Altram), it does smell terrible though. The mixture also seems to promote healing faster for cuts and abrasions, I would also assume it would stop any injury from getting infected, as the DMSO allows the CS to penetrate the area also have a mole or other skin conditions they seem to be getting hard, time will see they may clear up. Over all I am very happy with the results. This is for topical use only.
