Dr Douillard (Ayurvedic practitioner) suggests that before you do the full-bore liver flush, you "prepare" with much more than just the malic acid. Months before you do the flush, he recommends a serious regimen. Something or other there should have an affect, there's so much to try.
Go to the bottom of this page and ask for the free Ebook. It is 39 pages. Personally, I don't think you have to do ALL of his regimens, but if you read everything, you will probably be able to figure out just what is right for you. I am not convinced that you have to buy his herbal formulas, though they would definitely be helpful.
Also, his version of kitchari (part of the ghee cleanse)has too many spices but that is just my opinion. I use only turmeric, cumin & crushed coriander seed when I make kitchari. The important thing is to avoid fat after you take your dose of ghee every morning. Best of luck. I'm still studying this.
