Urine is rarely mentioned because of the deep adverse western cultural conditioning in play.
this goes back to Shiva and his discussion with his wife Parvati. She wanted to know the secret of his effulgence. Shiva agreed to tell her, but she must keep it secret.
This tradition carries on through today in Hindu culture. Advanced yoga practitioners around the world know about urine therapy/Shivambu, but only tell their advanced students about it. (kinda like here with you, I mention it only because of your advanced awareness of the benefits of fasting)
The current bible keeps an even tighter leash on this information with only vague references like; "Drink water from your own cistern, running water from your own well."
UT is truly revolutionary and would upset the western medical profession of butchery and deadly poisonous drugs.

Things like UT and Bitcoin are indications that perhaps the dawn of a new age is truly upon us...
We now know the tools to be our own doctor and our own bank.
