The Martha Christie book is a good read and has a good bit of scientific data. The urine therapy "bible", is called "The Water of Life" by John W. Armstrong which has numerous case studies of 'incurable' conditions. (both books can be found for free on the Whale site)http://whale.to/a/Water-of-Life-Treatise-on-Urine-Therapy-by-John-W.-Armstrong-1971.pdf
The pee represents real liberty. It is something the corporate powers prefer you not know anything about, as their racket is all about keeping power, control, while lining their pockets with your slavery.
There are numerous private groups active on facebook.

I attended the first annual 'Water of Life' symposium last September, really fantastic bunch of folks.
