In fact many major drug manufacturers now include DMSO for a better absorption for their medication..but they do not boast about it..
For the pundits-also Jim Humble has confirmed to me that he has used DMSO for many years and no adverse reactions when using it with Miracle-Mineral-Supplement too..
Yes , Colloidal Silver will repair damaged tissue..Many companies are incorporating it in their product like plasters,band-aids,etc..
Some natural health companies are also starting to include DMSO in their product like Soothanol X-2 apparently with amazing results..(not just web hype here)DMSO is also being incorporated into gels,creams,etc..
