What is it? I know it's used transdermally for pain. I remember some bad press it got. also I read on s thread here it's sulfur so maybe it's not good with a cbs mutation. I have the mutation but I'm pretty sure it's Non expressing. I have no problem with sulfur foods. I also take molybdenum. I'm getting pt for s bad shoulder and want a cream to add to my protocol One I found has dmso with arnica so I just wanted to check. Please tag me. Thanks Oh please dumb it down. I don't need technical info. Just basic so I can decide.
