Everything has its proper place. People who take pharmaceuticals and find themselves constipated or find being away from home or on holiday can upset the natural rhythm of our bowel movements. Laxatives can be useful for relieving the symptoms of temporary constipation, but continual use of laxatives can further constipate by paralysing your bowel. Enemas are useful for emptying the rectum/sigmoid, (the lowest 8-12 inches of the colon) usually 1-2 litres of water are used to do that. Suppositories are also used to accomplish the same task. Colonic Hydrotherapy has the ability to release waste from all areas of the Colon. Robert Gray M.D. estimated one Colonic treatment is equivalent to thirty enemas.
