Abstract: Based on the theory of "spleen-qi essence distribution", this study elucidates the application of Jiang Yuren's spleen-regulating method in the management of central precocious puberty (CPP) in girls. By demonstrating the role of spleen-qi essence distribution in child growth and development, this study establishes the pathological basis of the spleen's failure to distribute essence in CPP in girls. This study proposes three key pathodynamic processes, including spleen-qi dysfunction resulting in impaired essence distribution and phlegm-damp stagnation; compromised liver qi dredging due to spleen-qi stagnation and liver-qi depression, disturbing the Chongren system; disrupted spleen-kidney synergy leading to kidney yin deficiency and hyperactivity of ministerial fire. The therapeutic strategy, guided by Jiang Yuren's "spleen-regulating method", emphasizes regulating spleen-qi to distribute essence, resolving phlegm-lipid accumulation to stabilize Tiangui, soothing liver-qi to modulate Chongren system, and nourishing kidney-yin to restrain ministerial fire. This approach provides a new theoretical framework and clinical methodology in Chinese medicine for the management of CPP in girls.
