My herbal practitioner has her own method of liver flush. It lasts 5 days. On days one and 5 you eliminate all animal products. On the 3 days in the middle you take fruit and vegetable juices only. In the morning you prepare a "flush drink" with olive oil, ginger, orange juice and a few other things -- it tastes lovely. You also drink detox tea, and she gave me a mixture of herbal tinctures to take as well.

I got on with it very well and never felt hungry, though a little strange at times. I tried fasting since then and was about ready to pass out from fatigue and hunger, couldn't get through a day. This was a lovely and gentle way of cleansing the liver and I still took all my vitamins (though I didn't chelate).
