"Your body disposes most of its toxins via the urine after filtering through the liver.
To re-ingest would mean that all the toxins just dumped are re-introduced"
This sounds logical
However,I've read this;(amongst much more)
"If substances which leave the body via the urine are the same as those
involved in the illness process,they can stimulate the defence system
to attack and in this way fight the illness"
