Is this for the liver flush that involves an oil and epsom salt. It is actually a myth if so it doesnt actually cleanse the liver and the "gallstones" that come out are actually just a mixture of the above. Even dilating the bile ducts with epsom salt you couldn't pass these pseudo stones. Nor do we have 100 of stones like these people expell.
Best way to cleanse the liver is with bitter herbs on the back of the tongue pre meal.
