The colon is a sewerage system, but by neglect and abuse, it becomes a cesspool. When it is clean and normal we are happy and well; let it stagnate and our bodies will absorb the poisons of decay, fermentation and putrification into the blood, poisoning the brain and nervous system so that we become mentally depressed and irritable. It will poison the heart so that we become weak and listless, poison the lungs so that the breath if foul, poison the digestive organs so that we are distressed and bloated, and poison the blood so that the skin is sallow and unhealthy. In short, every organ of the body is poisoned and we age prematurely, look and feel old, the joints are stiff and painful, neuritis, dull eyes and a sluggish brain overtakes us, the pleasure of living is gone.
