My experience has been - after 30 years of hcv, my "internal medicine" MD told me: your "liver is enlarged". And it was; it was pushed out like a small cantaloupe.
Thinking I had nothing to lose; (the doctor was not being helpful; just dismissive) I went home and decided to try the liver cleanse in Dr Clarks book; which I had had for a couple years, but still found it hard to believe.
I expelled several hundred stones that first time; hundreds again, and so on until there was only chaff- after the 5th or 6th time.
My guess then is: if you do the same formula each time, but see progressively less stones; then it indicates that there is a purging of "stones", or you are getting out some "congestion" of some kind; maybe mixed with some stones.
Obviously the Epsom Salt diolates the bile ducks; if you have liver congestion already, the pressure is unmistakable. And then when you drink the oil/gfj, there is a direct "rumbling" in the liverwithin 20 minutes.
The more clear my liver became, the less pressure, and less rumbling.
It could be that these surgeons are finding left over, or new stones, and are unwillling to compare before and after cases.
BTW, my liver went immediately back to "normal". I'll never stop doing them.
I also get a surge in stamina 3 days after a good cleanse.
