Don't know...I've never [intentionally] tasted urine...Although I recall an episode of CSI where some fashionable women drank their own urine...From wine glasses, no less...

In Staging Battalion before leaving for WestPac Ground Forces, we were told that urine was sterile, and that urinating on a contaminated wound was an acceptable (or at least field expedient) substitute for disinfectant...

I wouldn't think it had salt in it...or it wouldn't be sterile...

They use saline solution all the time and its sterile.

Isn't saline solution pH neutral??? Brine is heavy on salt...To the point that it burns in open wounds...
