I proudly took the stones in the next day after a flush to my doctor. She barely looked at them and said they were "fecal matter". Totally blew off the whole idea of a liver cleanse. Of course she had no explanation when my cholesterol dropped from 281 six months before to 179 as tested during this appointment. Two months later her assistant called and said that she'd had the sample tested at the hospital lab and it was, of course, "fecal matter". The sample was green stones mixed with the tan chaff and bile that comes out with it. Okay, it didn't test as solidified olive oil like some doctors claim. And as far as I know the cholesterol, bile, and other stuff that we are passing are normally part of "fecal matter" just not usually in this quantity. So as far as I'm concerned she didn't settle a thing. The Clark lab receipt link is far more compelling evidence to me. Perhaps the only way to settle this is for one of us to convince an ND or other provider to send a sample to the Smokey Mountain Lab (supposedly the best lab in the country). Unfortunately an individual can't utilize them directly.
