I am still living after starting Urine Therapy (drinking urine ) in September 1996 and massaging urine (old) behind my head in October 1996.
Yesterday I had all sort of fleeting pains in my abdomen below the navel. I called Dr S. N. Bhavasar, PhD Sanskrit (www.spacetimemotion.com) and a person whom I trust for his "tapasya" (learning the Vedas and sanskrit) ---- he said, those pains are not due to kidney failure but because you are talking things to everybody.
In my humble opinion, Residues of medicines will be metabolized by the liver and excreted through the bile. That is why it is safe to ingest the product of the kidneys.
Residues of medicines may be excreted as urine and drunk by the person.
So residues of residues of medicine will get removed thru the liver.
Or residues of residues of residues of medicine.

He speaks, Hindi , Marathi, English and some German.
