Traditional Chinese Medical Theory for Digestive Disorders
In traditional Chinese medical theory, the Spleen is the key organ involved in gastro-intestinal disorders. The Spleen has primary responsibility for “transforming” and “transporting” food essence in the body, including the excretion of waste material. The Spleen and Stomach are Yin/Yang partners, and each one can develop characteristic problems. The Spleen needs to be somewhat moist in order to function well, but if it becomes deficient in Chi, it will become overwhelmed by moisture, and a pathological condition of Dampness (or Damp Heat) can settle into the body. The Stomach, on the other hand, needs to be on the dry side to function well, and when its balance is upset, it can easily overheat, and a painful condition of Stomach Fire can develop. Other organs, especially the Liver, can also contribute to gastro-intestinal distress. The four most common patterns seen when gastro-intestinal problems are differentiated are as follows: Spleen Chi Deficiency, which is caused by chronic fatigue or chronic illness; Damp Heat Retention, which is caused by improper diet, environmental factors, or infections; Disharmony of Liver and Spleen, which is caused by emotional disturbance; and Spleen and Kidney Yang Deficiency, which is caused by chronic illness or aging. To treat these imbalances, Chinese medicine commonly uses acupuncture, herbal medicine, and moxibustion. When applied properly, these modalities balance Yin and Yang, harmonize Chi and Blood, nourish the organs, and eliminate Damp Heat. Conditions which respond well to acupuncture, moxibustion, and herbal medicine include:
- gastrointestinal infections such as virus infections from rotavirus
- bacterial infections from salmonella, shigella or escherichia coli
- inflammatory diseases such as chronic gastritis, atrophic gastritis, chronic enteritis, and gastroenteritis
- peptic ulcers such as duodenal ulcer and gastric ulcer
- circulation problems in the gastrointestinal system such as gastrointestinal tract bleeding and intestinal cramps
- gastrointestinal tumors such as stomach cancer, tumors of the small intestine, or colon cancer
- inflammatory bowel diseases such as ulcerative colitis and Crohn’s disease
- other conditions such as irritable bowel syndrome and short bowel syndrome.
Moxibustion for Gastrointestinal Conditions
Traditional Chinese medicine employs several healing techniques to treat patients, including acupuncture, herbal formulas, and moxibustion. Acupuncture and herbs are familiar to most people in this country, but moxibustion is less well known. Moxibustion is a therapeutic technique of applying an ignited cone or stick of mugwort or other medicinal herbs over the affected part of the body or on the acupuncture points. Moxibustion is often used to warm up cold conditions, or to tonify deficient conditions, but it is also an effective agent against certain types of inflammation, and can be used to treat most gastro-intestinal conditions. Scientific Support How do we explain these beneficial effects of Chinese medicine modalities in a modern clinical sense? How does it work from the viewpoint of biomedicine? Numerous modern studies, most of them conducted at China’s leading research and teaching institutes and in hospital settings, show that acupuncture, moxibustion, and herbal medicine can bring about bio-chemical changes. The following are a few examples: Excretory Rate of D-Xylose. The excretory rate of D-Xylose is an index of the absorption function of the intestines. Patients with chronic gastritis, chronic enteritis, or peptic ulcer tend to have a lower excretory rate of D-Xylose. A number of clinical studies in China show that acupuncture and moxibustion can increase the D-Xylose excretory rate significantly. Serum Gastrin. Gastrin is a hormone in the digestive tract, secreted mainly by cells in the stomach in response to eating food. Gastrin causes the stomach to produce more acid and also stimulates contraction of muscles in the wall of the stomach, ileum, and colon. This contraction propels food through the digestive tract. A very recent study at the Affiliated Hospital of Sichuan Academy of Traditional Chinese Medicine found that moxibustion (moxa made with astraglus, codonopsis, etc.) at acupuncture points St 36, Ren 4, and Ren 12 can raise the serum gastrin level. T-lymphocytes and their Subgroups. T-lymphocytes and their subgroups reflect the status of cells’ immune functions. Substantial evidence shows that Spleen Deficient patients have a lower immune function at the cellular level. Clinical studies in China show that acupuncture and moxibustion can increase T-lymphocytes and their subgroups in the blood. Ache when working normally. In people who have GERD, the muscle relaxes at the wrong times, allowing stomach acid to churn up into the esophagus and resulting in heartburn symptoms. By applying only mild stimulation to an acupoint on the wrist known as Neiguan, researchers were able to reduce the frequency of TLESRs from six to 3.5 an hour in research subjects. Sham stimulation of a hip point produced no comparable change. Researchers cautioned that it’s still a big leap from these promising results to a reliable cure for GERD.
