I've just used the fresh urine for enemas. And use aged urine externaly on the skin. I read how month old urine is best and am experimenting with that.

I'm not sure what refrigeration would do other than slow the aging process.

I drink my first morning pee in entirety usually. This is a good indicator of how your,body is doing and how it's responding to your diet.

Start slowly aclimating by simply rubbing some fresh pee on your skin, work up to swishing in you mouth.
Many say putting fresh urine up the nose is very good, I'm kinda working upmto that.

The healing processes vary depending on what you are dealing with.

Much of it is about becoming more aware and in tune with yourself, it can take some time, be patient.

Read up the John Armstrong and van der kroon books.

I still haven't read the Martha Christie book but look forward to doing so.
It's a process of becoming your own doctor, read as much as you can and experiment some.

Hope that helps some
