You may want to take the directions for the liver flush from my book, The Amazing Liver & Gallbaldder Flush, http://www.ener-chi.com. Not doing a colon cleanse after the liver flush can cause major toxicity in the intestinal tract and affect the liver and digestion of food. Not doing a colon cleanse before the liver flush, can prevent the bile ducts and gallbladder from properly opening up during the liver flush, especially if the colon is clogged up. In addition, not softening the stones for 6 days prior to liver flushing makes it much more difficult for the stones to come out. Liver flushing can be a powerful method to improve your health, but if not properly performed, it can do more harm than good. Most headaches stem from colon congestion. Anger affects the behavior of cells and can change the bile flora, but the liver flush would still work if done properly.
