I have wondered about this too, but in my case, it sure seems like a
LOT
more came out than went in.  Also, when I did Richard Schulze's bowel
cleanse, which uses only herbs and no psyllium or bentonite, or
enemas, a
lot of stuff came out as well, far more than my usual bowel movements.

For my own cleanse, I used a product that had no bentonite (Ejuva).
The
maker had spent years trying to find a bentonite that he felt was
safe.
Most bentonite has lead and aluminum per his analysis.  He gave up on
looking and built a formula without it.

I personally believe that only a healthy colon experiencing a healthy
diet
sheds the scum build up.  I have seen pictures of colon cross sections
from
autopsies.  The build up was gross.  There is also the story of John
Wayne
who died of cancer, his colon weighed in at 37 pounds due to the build
up.
