The core pathogenesis of chronic atrophic gastritis often involves weakness of the spleen and stomach, as well as disharmony of qi and blood. The “Balancing and Restoring the Source” method aims to regulate imbalances in yin and yang, deficiency and excess, zang⁃fu organs, qi and blood, cold and heat, as well as ascending and descending, thereby achieving a healthy state of balanced yin and yang, and adequate generation of qi and blood. The empirical formula “Piwei Peiyuan Prescription”, developed based on this method, has shown significant clinical efficacy for the treatment of chronic atrophic gastritis. This article explores the theoretical foundations of the “Balancing and Restoring the Source” method and summarizes relevant clinical experience for treating chronic atrophic gastritis based on this principle, with the aim of contributing to clinical diagnosis and treatment.
