I actually found that first link in my first searches about urine therapy. It appears to me that this is the starting place for a renewal of using Urine as Medicine. I believe urine as medicine has amazing potential from my own observations. When I did my other blogs, I found a lot of research by googling Double Blind Study + Whatever I was researching. I have not come up with any so far with Urine Therapy or Urea and Double Blind Study. That doesn't mean they are not out there. I just have not found the right combination of words. Thanks for the links.
