urine in juice?

I'm very new to this. Can you put fresh urine in juice before drinking it without hurting any of the healing properties? I want to try this, but I'm scared to. I thought if I put a small amount in some juice and started from there, I could try it. Is UT externally good for fine lines on face. I remember a story my mom used to tell me of an Great-Aunt I had who would soak a clean cloth diaper in urine and rub on her face several times a day. What would be the best method of using this on my face for fine lines? Could I use organic cotton pads? Thanks for your time. I'll probably have lots of questions to bug you all about in the coming weeks. Tweet
