I took all the common ingredients for a Hulda ClarkLiver Flush including olive oil, epsom salt, and citric acid . I added lecithin to simulate bile and cooked it around and strained it and what I got looks a lot like supposed "liver gunk". While this test did not give stones, so if you get bile stones out they are real, but any soft clumps can be explained just from the ingredients reacting together. Also citric acid is not a gall bladder stimulant from what I can find, but bitter herbs are so using andrographis or longjack would be better.
