That's a very good result since you have not done the recommended preparations. Hulda Clark wrote that if you have parasites in the bile system you will not be able to clear out all the stones and sludge. If you have hard stones they will also continue to block the bile ducts and may not come out of the gallbladder. The featured programs include parasite cleanses and a way of dissolving or softening hard stones. Some people also take herbs or supplements to help break up the hard stones and these methods are mentioned in their messages. H. Clark advised doing LFs until you get out 2000 to 3000 stones then do the Liver-Flush yearly. Some programs advise to keep flushing until you are not passing stones on 2 consecutive LFs. It may be necessary to treat an intensinal problem before you stop making stones and keep having to flush them out. If your body is too acid this promotes stone formation and there are supplements and diets to help this problem.
