Outwitting Our Nerves: A Primer of Psychotherapy

by Josephine A. Jackson; Helen M. Salisbury

What the Colon Is For. It is well, then to have a fair understanding of the structure and purpose of our intestinal machinery. Contrary to general opinion, the

intestines are not a dumping-ground but a digestive organ. After the food is partly digested in the stomach, it passes through a twenty-two foot tube (the small intestine) into a five-foot tube (the large intestine or colon) where digestion is completed, the nutriment is absorbed, and the waste matter is passed on and out through the rectum. As the food passes along the colon, pushed slowly ahead by the peristaltic wave, or rhythmic muscular contractions of the intestinal wall, it is seized upon by the four hundred varieties of friendly bacteria which inhabit the intestines of every healthy person, and is changed into a form which the body can assimilate. Digestion in the stomach and small intestine is carried on by means of certain digestive juices, but in the large intestine it is the bacteria which do the work. Without them we could not live.

Around the colon is a thick network of little blood vessels, all of which lead straight to the liver, the storehouse of the body. After the food is fully digested, it is passed through the thin intestinal wall into these tiny vessels and carried away to liver and muscles for storage or for immediate use.

This process of absorption is carried on throughout the whole length of the colon. Not until the very end of the intestine is reached is all the nutrition abstracted. The bowel-content can properly be called waste matter only after it has reached the rectum or

pouch at the lower end of the colon. Even then, this waste matter is not poison, but merely indigestible material which the body cannot handle.

Food, not Poison. The colon is not a cesspool but a digestive and assimilating organ. Its content is not poison but food. Active elimination is important not so much because delay causes autointoxication or poisoning as because too large a mass is hard to manage and irritates the intestinal wall. The problem is not so much one of toxicology as of simple mechanics. If Nature had put within the body five feet of tubing which could easily become a cesspool and a breeder of poison, it is not at all likely that she would have laid alongside an elaborate system of blood vessels leading not out to the kidneys but into the storehouse of the liver; and if civilized man's changed manner of living had so upset Nature's plans as easily to transform his internal machinery into a chronic source of danger, we may be sure that he would long ago have gone the way of the unfit and succumbed to his own poisons.

Possible Invasions. It is true that the intestinal tract, like the rest of the body, is open to attack by harmful bacteria. But in a great majority of cases, these enemy bacteria are either quickly destroyed by the beneficent microbes within or are immediately cast out as unfit. Any germs irritating to the intestinal wall cause the mucous membrane to produce an unusual flow

of mucus which washes away the offending bacteria in what we call a diarrhea. [52]

[52] ] If the invading army proves obstinate and the diarrhea continues a day or so, it is wise to assist Nature by a dose of castor-oil, which gives an additional insult to the intestinal wall, spurs it on to a desperate effort, and hastens the cleansing process. In severe cases the more promptly the castor-oil is administered the better. Such emergency measures are very different from the habitual use of insulting drugs.

Sometimes the wrong kind of bacteria do persist, causing anemia, rheumatism, sciatica, or neuritis. When these disorders are not the result of infection from teeth, tonsils, or other sources of poison, but are really caused by intestinal bacteria, I have found that a diet of buttermilk (lactic acid bacteria), with turnip-tops or spinach to supply the necessary mineral salts, often succeeds in planting the right bacteria and driving out the disturbing ones. These disorders are invasions from without, like tuberculosis or malaria, and are as likely to attack the person with easy bowel movements as the one with the most chronic constipation.
