This site recommends more than just one way. I think that on the Liver Flush page, there is a link at the top that lists several different flushes. I understand that Dr. Schulz has a 5 day or weeklong cleanse, herbal. I think that the small dose of lemon and oil everyday is also one of the flushes. It is more of a long-term flush but if you're willing to do it, I would suppose you would see the benefits. I'm not an expert, but I did want to point out that it there are several other legitimate Liver Cleansing programs.
