I have tried injesting it, it's not as bad as I thought it was going to be, just a little salty. Although it is hard to get past the inital idea and also just the process of collecting it seems odd. I don't think I injested enough for an extented period of time though to really notice much difference.
What I definitely know it does work wonders on is on minor cuts and scrapes applied topically. I have never had minor wounds heal faster with anything else. It's seriously amazing, I can fully attest to it!
In fact, one of the best case senarios for me was just recently I had a problem with my upper lip. It was extremely dry from the winter, cold sores, and because of licking it and applying all sorts of goop to it I think it eventually became infected. After a while nothing was working on it at all. I started to get really worried that if it was infected that it was going to spread to my bottom lip. So I did a little research and found that one of the suggestions to remedy dry lips was to put Neosporin on them so if in fact they were infected that that would help to heal it. Well, I knew that urine had Antibiotic properties so I thought well, I tried it on my minor cuts and scrapes with tremendous results so I thought it couldn't hurt and it wouldn't cost me anything. ;) And just as I had hoped it started to heal it right away. So when I went to the bathroom for about a day or two I just applied it at the same time. (just as a guess, maybe 8 times or more?) So within two days it was completely healed! I mean, I know it sounds kinda weird, but it really worked!
