Hi Elizabeth,

As long the donor is of same gender specially if you are planning on drinking the donated urine for long time. Also the donor should be free of auto-immune and any diseases, then it should be ok.

When you read the Water of Life, John Armstrong describes in severe cases he would administer his own urine for some who were unable to produce thier own.
The patients own urine is always preferable.

But urine from any mammal will likely be helpful.

I have a dog who suffered a very nasty head wound. By the time I saw it, it was very inflammed and ugly. I live very far from any veternarian.

I grabbed him and held him dowm and poured my own fresh pee into the wound,he freaked out and I nearly got bitten for my trouble, but the wound healed up fairly quickly, even with just one application of my urine.
