DMSO is an organic sulphur compound that comes from the dead trees..so is MSM which is DMSO2.. I have a big jar of MSM that I take and plan on trying it with sublingual pharma one day soon.

Ayway DMSO has never been found to be toxic in any way at all. You can literally just take tons of the stuff. In studies they have actually dipped rats right into the stuff without any negative side effects at all.

The only real thing to worry about with DMSO I think is that you want to make sure you are not in contact with other toxins at the same time because the DMSO will carry them into the blood stream.
