荣卫–胃–冲脉一体论：仲景医学的一条隐性主线

On the Integration of Wei-Defense, Stomach and Chong Meridian: A Hidden Theoretical Line in Zhang Zhongjing’s Medicine

摘要: 仲景医学中，荣卫、胃、冲脉长期被分而论之，未成体系。三者可整合为统一理论框架：胃为气血之生源，冲脉为气血之蓄聚，荣卫为气血之运行。三者非分工协作，乃同一根本气血在不同环节的显现，互为表里，同步联动。以此重审仲景诸书，《脉经》卷九三篇妇人诸证、桂枝苓桂建中温经诸方，其病机与立法均指向这一整体结构。叶天士据此提出“久病入络”与“通补阳明以治冲脉”，乃将此体系向临床纵深推进。荣卫–胃–冲脉体系的建立，贯穿伤寒、杂病、妇人诸证，并为络病理论提供根基。

Abstract: In the medical system of Zhang Zhongjing, Wei-Defense, Stomach and Chong Meridian have long been discussed separately without being integrated into a coherent framework. This paper proposes that the three can be unified into a single theoretical system: the Stomach serves as the source of Qi and blood, the Chong Meridian as their reservoir, and the Wei-Defense as their functional manifestation in circulation. They are not three independent entities engaged in division of labor, but rather different manifestations of the same fundamental Qi and blood at different stages of their cycle—interrelated, mutually responsive, and synchronously linked. Re-examining Zhang Zhongjing’s texts through this lens reveals that the gynecological conditions recorded in the three chapters of Volume 9 of the Mai Jing (Pulse Classic), as well as the formulas Guizhi Decoction, Linggui Zaogan Decoction, Xiaojianzhong Decoction, and Wenjing Decoction, all point to this integrated structure in terms of both pathogenesis and therapeutic strategy. Ye Tianshi subsequently developed the theories of “prolonged illness entering the collateral vessels” and “tonifying and unblocking Yangming to treat the Chong Meridian,” which further advanced this system in clinical practice. The establishment of the Wei-Defense-Stomach-Chong Meridian system runs through the treatment of external contraction diseases, miscellaneous internal disorders, and gynecological conditions, and provides a foundation for the theory of collateral diseases.
