DMSO Mouth swish.

Any DMSO experts here? My husband has been on a 40-day IV protocol which is DMSO-based, as well as a DMSO-based mouth swish...he had an oral tumor removed.

We have to buy this stuff in a tiny little bottle which barely lasts a week and we have to order it from Tulsa. I'd like to try making my own using a good quality DMSO and maybe tumeric and/or Pau D'Arco, but I'm just a tad hesitant since I don't know what I'm doing.

Should the DMSO be diluted? I'd really appreciate advice from someone with some knowledge on this.

Thanks,
Judy
