Urine, on being taken into the body, is filtered; it becomes purer and purer even in the course of one day's living upon it, plus tap-water, if required. First, it cleanses, then frees from obstruction and finally rebuilds the vital organs and passages after they have been wasted by the ravages of disease. In fact, it rebuilds not only the lungs, pancreas, liver, brain, heart, etc., but also repairs the linings of brain and bowel and other linings, as has been demonstrated in the case of many "killing diseases", such as consumption of the intestines and the worst form of colitis. In fine, it accomplishes what fasting merely on water or fruit juices (as some naturo-paths advocate) can never achieve.
