[Professor LIN Guo-hua's experience in the clinical application of "Dayingxiang"].

The paper introduces professor LIN Guo-hua's experience in treatment with acupuncture-moxibustion at "Dayingxiang". Based on the application of Neiyingxiang (internal LI 20), professor LIN defines the entire nasal cavity and its adjacent nasopharynx as "Dayingxiang", of which, "Neiyingxiang" and "Biyandian" (nasopharynx point) are commonly stimulated with acupuncture-moxibustion. "Dayingxiang" may regulate lung qi and promote the circulation of the marrow sea in treatment of the disorders of lung system and the marrow. Fire needling with twirling or burning-scallion technique is predominated in manipulation. "Neiyingxiang" is stimulated for the shallow-located disorders, while, "Biyandian" is for the deep-located ones. These two points are optioned alternatively or in combination to enhance the therapeutic effect.
