Been using DMSO for years on burns. You forget you even burned yourself after 5 mins and usually not even a burn mark/lesion(used only on minor burns). While backpacking Ecuador I met an American Dr who moved down there because he couldn’t use DMSO for cancer treatment in the states. His clinic had thousands of successful treatments and only one death from someone who went to the hospital and ended up dying of pneumonia. I forget the name of the drug he would combine it with(some cancer treatment drug) and then would give it intravenously. You can buy it from Amazon as a topical gel mixed with aloe. Use a clean q tip to apply so you don’t contaminate your jar and use sparingly as very little is needed.
