There are a number of characteristics present when the bowel has been well cleansed, provided that a healthy Diet is consumed that is void or low in mucoid-forming foods. The bowels will move 2-3 times per day...usually shortly after a meal has been eaten. The quantity of feces tends to be greater as it contains more moisture and therefore less compressed. The stool passes from the body very easily with no straining and is neither runny or mushy. It is smooth and cylindrical in shape, walnut brown in color (unless the diet contains a significant quantity of carrots, beets, greens, etc. that result in corresponding colors). It has little or no odor, and generally exits the body in one long piece...not smaller pieces lumped together. The feces are fully formed, initially float and then slowly submerge, and should begin to crumble when the toilet is flushed. Once cleansed, the colon can maintain a high concentration of healthy flora...which is not possibile in a toxic colon.
If you're having different colored stools this is usually the result of toxins and an accumulation of old material that has remained in your colon. Check out the Bowel Cleanse Forum for more information.
