I'm wondering if the urine may still be bitter but doesn't taste that way to me because I may be getting used to that bitter taste. Bitter things are very good to help balance the body chemistry. I used to take Bupleurum and other bitter things to decongest my liver. People also take Chinese Bitters for some things.
Anyway, I have no doubt that urine is the perfect health tonic for mature people that want to improve their health. I won't tell my sister about it though. She wouldn't even open up enough to try oil pulling, yet she's had a few chronic health problems. If I told her I was doing UT she'd think I was totally out of it.
