Any imbalances in this system will affect nutrient absorption and other body systems. For example, in the circulatory system this could cause toxins to be absorbed into the bloodstream and harmful stagnation in the elimination area. Nutrient rich foods like vegetables and fruits are most important here.

The Intestinal System has been called supplements the body's waste disposal plant. It is part of the digestive system and includes the small and large intestines and the rectum. In the small intestine, vital nutrients are absorbed in the blood. In the large intestine, water is absorbed from the digestive waste which is subsequently eliminated from the body. The efficiency of the system results from good muscle tone, a healthy bacterial environment and sufficient amounts of fibre to give bulk to the stool.

Here too, imbalances will affect all other systems. The result will be a general decline in health caused by the build-up of wastes and toxins. Some of the common concerns might be constipation, diarrhea, colitis, crohn's disease, etc. Herbalists traditionally start a health improvement program with a cleansing of the intestinal system before moving on to other areas, in order to carry away these build-ups of waste and toxin.
