Fasting not only brings absolute comfort to those who have a fatal "disease," but it brings comfort in every other "disease," cuts all "diseases" short, and gives the sick man or woman the very best opportunity and the surest road out of suffering into health. Dr. Shew wrote: "Very seldom will toothache withstand twenty-four hours of entire abstinence from all food."--Water Cure in Pregnancy and Childbirth, p. 63. Again, he wrote: "If a person has a toothache--no matter how bad--provided there is not swelling and ague in the face, it is cured with certainty within twenty-four hours by abstaining from all food and from all drinks, except water. At any rate, I have known no case where such treatment has failed of complete success."--Family Physician, p. 796.
