To me the proof is in the pudding, there is much testimony proving the healing success of distilled water my own use of distilled water and others I know. There is Braggs success story I posted earlier and there is the great success Dr. Carey Reams has at his cancer clinics with his distilled water therapy curing 99.9% of his 10,000 patients. I also have noticed the large influx of anti distilled water promotions since the advent of these home water purifiers, its a shame so many have turned against the great cleansing and hydrating abilities of DS because of some companies need to increase their profit margin.
