Thanks again for all this info. I've read a lot about DMSO and its use along with chemo. Fortunately, my father is not doing chemo, only radiation. Also, I remember you suggested DMSO to be simply rubbed into the skin for oxigenation (I guess), but we are causious about doing it along with radiation because DMSO, being a strong antioxidant, can neutralize the effect of radiation.
Also, I've tested my father's saliva, and its pH = 8. Isn't it too alcaline?
