In traditional Chinese medicine (TCM), gastroenteritis is often seen as a result of imbalances in the body’s digestive system. This imbalance can be caused by a variety of factors, including stress, an unhealthy diet, and overconsumption of alcohol or spicy foods.
To treat gastroenteritis in TCM, a practitioner may use a combination of techniques, including acupuncture, herbal remedies, and dietary changes. Acupuncture is believed to help regulate the flow of qi and blood in the digestive system, reducing symptoms such as abdominal pain and diarrhea. Herbal remedies may include the use of herbs such as ginger, licorice, and mint, which are thought to have a positive effect on digestive health. Dietary changes may include recommendations to increase the consumption of foods that are easy to digest, such as rice, soup, and cooked vegetables, and to reduce the consumption of foods that are difficult to digest, such as raw vegetables, dairy products, and fatty foods.
