So this means that there are some advantages of these liver flushes though not in terms of Gall stones or liver but in terms of intestinal cleansing and bile flow?
I emphasized "small" amounts of oil in my post. Not the large amounts used to contract the gallbladder. Again strongly contracting the gallbladder increases the risk of lodging a stone in to the bile ducts, which will require emergency surgery. In fact I think it is highly foolish to attempt "liver flushing". The risk of lodging a stone is too high, and the only think that may happen is small gravel may be passed. But helping to pass gravel and prevent its formation can be done safely with the ingestion of small amounts of oil with meals as I mentioned.
Again, small amounts of oil with meals is good since it helps to stimulate bile release so it will not become stagnant.
