I'm using 100% purse DMSO on my stomach and 4 times it has immediately pulled my out of Crohn's flare when nothing else is working. I notice results within an hour. Sounds really strange but it has been a miracle for me. Please everyone research. It may not help everyone but if it helps some of us it's worth the effort. I paid $20 for a bottle at a local holistic store. I was reluctant to try it and i'm still shocked at my results!!!
