Aged Urine for Enemas/Eye Wash

I've been using the internal therapy (approx 1/4 liter/day) for a little while, with some good results.

Also used aged + fresh urine on the skin, and also one enema using as fresh as possible.

I've read a few posts regarding the aged urine - for example that it can be used in enemas and for eye bathing. I've got v. bad eyesight (-12) but can see fine with glasses/contacts - though reading close up can be a problem.

Anyway there are multiple posts warning not to drink urine after around 15 mins due to pathogen and ammonia build up. So I wondered if especially the pathogen issue might cause problems, for example if there is a slight scratch on the eye surface. Some of the pathogens might come from the air, so will have no direct relation to the body. In this case I would wonder if it would be particularly good in an enema?

If any contaminated nutrient is left at room temperature I would of thought the bacteria numbers could increase exponentially. I guess what I'm saying is that it might make more sense to keep this at fridge temp until using? In many ways I hope not, 'cos my SO might freak - and we dont have much free space in the fridge anyways.

I think this is my first post on this forum so Hello Forum Members:-).
