I have been using and recommending DMSO for many years! It cured my arthritis, and has cured three people I know of cancer! Yes, even stage four cancer! DMSO is a miracle drug! I do not recommend drug to be taken for preventative reasons, but I think DMSO can even help to clean the arteries and heal the heart, as I have also lived with an irregular heartbeat all my life but I've noticed that after taking the DMSO for my arthritis my constant irregular heartbeat has also vanished and now only once in a while feel my heart out of rhythm and even them not as pronounced as before!
I've been an herbalist most of my life and DMSO and wild lettuce have impressed me more than anything else!
