I know it its supposed to be very healing increases blood flow to the area and takes what ever its mixed with into the body deeply for this reason you need to have very clean hands when using it or else it will take what ever is on your hand into your body ( If applying topically) for the mouth I just add a few drops to a bit of mixed MMS and some water thats vague Jim gives the receipy for this for mouth wash. Are yoo working with healing your lungs ok got book Dmso natures healer morton Walker Re lungs he says " by adding penicillin or streptomysin to Dmso for an inhalant, TB resistance to these antibiotics is partially avoided . It also carries antibiotics to reduce middle-ear infection in children.
