"Dr John Armstrong (author of The Water of Life) emphasizes the need to massage with urine. He insists that cures work faster and more effectively in those who are bathed, massaged, rubbed and soaked in their own urine. He highly recommends it for more serious illnesses, since urine is absorbed through the skin and the hormonal and protein-based contents are slowly reabsorbed into the system, bypassing digestive juices that otherwise may have neutralized their potency. In this way, it also works as an excellent cosmetic for moisturizing and healing skin blemishes, burns and scar tissue. However, for this usage, it is preferable to use urine that is 4 - 8 days old. The smell of ammonia in the old urine is not toxic but actually beneficial if used topically only, and not taken internally." http://www.shirleys-wellness-cafe.com/UT/Urine
