If worried about doing liver flush:

Another thing to help lessen the fear is take Gold Coin Grass for at least 2 weeks before the liver cleanse, as this is supposed to help crush and soften the stones so that it's easier for them to come out AND much less of a possibility of any getting stuck - not that there are loads of cases of stones getting stuck. But I thought I should mention the Gold Coin Grass because many have used it with great results.
