Abstract: Being common symptoms in clinic， both nausea and vomiting are the characteristic reflection of failure of descending of stomach-qi from Diagnostics of Chinese Medicine. This paper probes into the view of "vomiting location being spleen rather than stomach"， based on the record in Miraculous Pivot that such symptoms as nausea and vomiting only belong to diseases of spleen meridian of foot-taiyin. Furthermore， a theory that "vomiting due to dysfunction of five viscera will lead to discomfort of stomach" is put forward， according to the relevant discussion in Huangdi's Canon of Internal Medicine and Treatise on Febrile Diseases. By analyzing the pathogenesis， treatment and prescription of vomiting due to dysfunction of five viscera， treatment rules that "stomach regulation can't be neglected though vomiting location isn't in stomach" is summarized， revealing that Chinese medicine emphasizes more of syndrome differentiation than symptom differentiation.
