目的：探讨伤寒舌诊中腻苔概念的形成。方法：查阅46部伤寒病舌诊医案，摘录与滑、腻相关的医案，并以“腻”为关键词，检索《中华医典》中有关腻苔的著作，并进行分析。结果：随着时间的推移，伤寒舌诊医案中对滑苔的记录呈下降的趋势，而腻苔的记录呈增长的趋势。明代方有执的《伤寒论条辨》是最早在滑苔中描述苔“腻”的著作。经过滑、腻并存的时段后，腻苔成为一个独立的舌象。结论：腻苔是从滑苔中分化出来的舌象，是伤寒舌诊研究的成果之一，同时也使我们认识到伤寒舌诊与温病舌诊的内在联系。

This study was aimed to discuss the relationship of tongue diagnosis in cold-induced febrile disease and the formation of greasy fur. By reading 46 typhoid tongue medical case books, cases with slippery fur and greasy fur tongue diagnosis records were extracted. Meanwhile, cases had been searched in the Chinese Medical Classics CD with keywords of "greasy fur". These cases had been chronologically arranged for further analysis. The results showed that the records of slippery fur in the typhoid tongue diagnosis cases showed a decreasing trend, while the greasy fur records had an obvious growth. And the earliest record of greasy fur can be traced back to Shang Han Lun Tiao Bian by Fang Youzhi in the Ming dynasty. It was concluded that greasy fur was originated from the slippery fur. And this achievement came from the study of typhoid tongue. At the same time, the inner relation of typhoid tongue and warm disease tongue was revealed.
