Andreas Moritz once mentioned it, his mother used it and cleared up a kidney infection.
After that I checked the urine support forum and read the R's for more information.

I thought the funniest story was that the PortaJohn company is now collecting the urine for a company thats makes different products. Indeed it does not sound attractive, rather use my own :)
