The first few times I did the liver flush, I didn't get much of a reaction either. Then I read Hulda Clark 's version of the flush and she said "If you have parasites in your liver, you will NOT have a good flush." So I took the Black-Walnut Hull extract that she recommended, and wham, the best flushes of my life. (Dear Hulda, she's been dead for years, and she's still helping people.)
