关于“阳有余,阴不足”之辨

The Debate on Surplus Yang and Deficient Yin

从天道阴阳、生理病理阴阳以及辨证论治等 ３个方面，重新比较了发生在１２世纪至１７世纪医界有关阴阳有余不足的一场辩论，认为争辩双方的实际分歧在于病理与辨证论治方面。这场争辩的理论意义是，促进了温病学说的形成。伤寒论与温病学是传统医学治疗外感病的两大学派，因此湿病学的形成标志传统医学在传统范围内的完善化，而围绕“阳有余，阴不足”论展开的这场辩论，正好反映了传统医学完善化之前的深刻的理论躁动。

The debate on surplus yang and deficient yin in the 12th to 17th century is described. The opinions of the two sides on the three aspects: vin-yang in nature, vin-yang in physiology and pathology, and syndrome differentiation, are compared. The author believes that the actual difference between the two sides lies in the pathology and syndrome differentiation. The theoretical consequence of this debate is the establishment of the theory on epidemic febrile diseases. The two theories, that on febrile diseases and that on epidemic febrile diseases, are the mainstay of the theory of traditional Chinese medicine, so the establishment of the latter marks the perfection of the theory of traditional Chinese medicine in the traditional domain. Therefore, the debate on 'surplus yang and deficient yin' reflects the theoretical restlessness before the perfection of traditional Chinese medicine.
