Chronic atrophic gastritis (CAG) has attracted wide attention in clinic due to its high incidence rate and high canceration rate. At present, modern medicine lacks an effective treatment scheme for CAG. Traditional Chinese medicine can improve clinical symptoms, laboratory indexes, pathological examination results and patients’ quality of life for patients of CAG. Professor Wei used the method of “Balancing Digestive Functions by Regulating Pivot” to treat CAG in clinical practice. With flexible addition and subtraction on the basic prescription Banxia Xiexin decoction and coordination with various external treatment methods and psychological construction, professor Wei has achieved satisfactory clinical effects with the pungent-opening and bitter-descending method and dispersing liver and promoting blood circulation method.
