If you will search Google and Youtube you will see where a Japanese doctor, and his colleagues, tested the effectiveness of urine therapy. He said that it has no curative effect, but is helpful in letting the body know how to heal itself. He recommends gargling it and drinking just a little. Why? Because in the research they found that people who got the urine through tubes in their stomach got no benefits. People who rinsed out their mouths after drinking the urine got no benefits. The idea, per him, is to let the back of the throat sense what is in the urine, and that makes the body know what needs to be corrected.
Urine therapy heals EVERYTHING because it does not attack the disease directly. It strengthens the body's own healing energy/system.
