Most peoples blood is too thick with cholesterol and fat. One of the major jobs the liver does when it is healthy is remove fat from the blood. When it is not so healthy, and the bowel ducts are stuck, and the gall bladder is filled with mucus, cholesterol or stones - then your circulation is very poor. The liver thins the blood viscosity. If the blood is thick, you get a lot less blood supply to the areas in vital need.
People change their sex life just from doing the bowel and liver cleansing - especially men.
One of the things that gives a man an erection is adequate blood supply. Folks doing a proper liver and bowel cleanse see dramatic difference. With the prostate congested and enlarged, they can experience impotency. The cleansing programs improve this situation within weeks. The liver also controls your energy level throughout the day by regulating the supply of glucose to feed your brain and keep your body awake.
