RESUMEN
The ancient discussion and modern clinical application regarding Yingxiang (LI 20) and Neiyingxiang (EX-HN 9) in acupuncture verses are explored. Acupuncture verses are the summary of clinical experiences of acupuncture scholars in the past dynasties, of which the records on application of Yingxiang (LI 20) and Neiyingxiang (EX-HN 9) mainly focused on nasal, facial and head-eye diseases, which is characterized with overall summarization, brilliant exposition, simple language, and distinctive characteristics. Nowadays, based on the ancient usage, the clinical application about these two acupoints is continuously developing. If the ancient acupuncture verses could be understood thoroughly, the clinical practice could be better guided and its effects could be improved.
