Reading back, I admit I really did misunderstood your message, apologies brother. I just couldn't quite wrap my head around the idea since some people do drink urine and have seen it with my own eyes either for some religious beliefs or as a traditional remedy for some ailments. Maybe that's why my thoughts immediately jumped into direct consumption.
But yes, I do believe that any possibility should be looked at and studied and if it does give out significant results, then there are lots of ways to remove impurities or any unwanted substances from whatever remedies are there by then, be it urine or not.
Animals don't evolve to waste good things, and no animal I know of consumes it's own urine as a normal operating procedure. I would expect that in 'normal' times urine has simply nothing particularly valuable. Clearly it doesn't kill a person either provided it is not contaminated, and anyone who has forgotten to flush the toilet can attest to the fact that it becomes rancid pretty quickly even if (again, in the normal case) it starts out sterile.
In corner cases where, say, one is fighting a (non-bladder) infection or some such, I could imagine it containing mis-filtered antibodies, antigens, exosomes, etc which if re-consumed into the digestive system would spur an increased efforts by the immune system to target appropriately. Even here though I am dubious because if the practice were truly effective, I would anticipate that one would experience a palpable desire to drink one's own urine during certain kinds of illness, and I've never felt such a desire. That would be just one hypothetical. The body with all it's systems, feedback loops, interactions with the environment, etc, is pretty damned complex.
Again, I'm not saying that there is ever any reason at all to drink one's own urine. Simply that someone telling you 'no, never' under the auspices of knowing everything there is or ever will be to know about medicine and science is unlikely to be qualified to do so. They probably think they know more than they do.
Or they are trying to pump some talking point designed by social engineers and thought to be possibly effective at herding the sheep in for 'their' shots. And then pushed out for distribution to the troll farm '
social media influencer' contractors. I've seen the Urine thing pushed out in various other outlets as well. Other examples of this 'messaging campaign' phenomenon include:
- '
I've shot up so many street drugs that I can handle Pfizer/Moderna whatever is in it' and
- '
I and my partner, are so excited and cannot wait to get the shots.'
