When I was in 3rd grade I was tricked (don’t ask) along with some other kids into drinking a 4th grade bullies urine…I only had a sip but imagined all sorts of horrible health problems for days but after reading this maybe I should have imagined the opposite.
Medical researchers have discovered that many of the elements of the blood that are found in urine have enormous medicinal value, and when reintroduced to the body, they boost the body’s immune defenses and stimulate healing in a way that nothing else does.
I’m sorry, but I’m going to be blunt.
The “Law of Similars” that the site referred to above mentions (a basis for homeopathy) is a load of crap.
The site disingenuously uses the example of the weakened form of virus used in many vaccines. This is not a homeopathic technique. It is based on the principle that exposure to a virus allows our immune system to produce antibodies to that virus (or other pathogen). The “Law of Similars” refers to the principle that when confronted with an ailment, the ailment should be treated with a medicine that causes the same symptoms as the ailment. For example, an itching rash could be treated with poison oak or poison ivy. The (in retrospect… remember this was invented before the age of scientific medicine) obvious failure of this law led Hanneman (spelling by memory, please forgive me if I’ve misattributed the Law of Similars) to develop his (also in retrospect… this was before Avogadro’s Number was known) insane ideas about infinite and near-infinite dilution, which make modern homeopathy the scam that it is today.
When I clicked on your link, the first thing I saw was a discussion of homeopathy. That was a real time-saver since homeopathy is a load of crap, which is somehow appropriate given the topic.
No, apparently the usual crowd of new age/alternative medicince cranks have made this “discovery.” The whole site is a typical collection of quackery.
Take a look at this quote from the urine therapy page.
Yes, research that could fill volumes. And yet, somehow, it doesn’t. The paranoid conspiracy theory twist is a nice touch, too.
All I can say is if you are going to try urine therapy, you should definitely do it in keeping with homeopathic principles. 
Cecil has something to say about it here:
