The largest portion of the intestinal flora is attached to the colonic wall and will not let go very easily. During the Colonic cleanse purified water is used. This keeps the intestinal flora in balance as it was prior to the treatments. Often the intestinal flora becomes disrupted, however, and it is therefore wise to use a product to bring the intestinal flora back in balance during or immediately after the colon hydrotherapy. Only removal of unfriendly bacteria in the large intestine (colon) occurs. Friendly bacteria is easily replaced. We encourage adding an electrolyte drink in your diet to improve hydration and balance and probiotics to improve the intestinal flora.
