Urine therapy saved my life, (kidney infection) and though I can see the reasoning behind condemning it, I can't get past the fact that if I had not done UT, I might not be here anymore. Perhaps there were other cures available I was not aware of at the time, but UT worked dramatically within one day initially, and another three weeks or so for full recovery.
I realise, as you have said, that most herbal medicines are poisons in small doses, so couldn't this also apply to urine?
