[Discussion on the theory of -sea point in () and ( )].

By collecting and analyzing the explanation/conception, acupoint name, acupoint location, indications, acupuncture and moxibustion techniques and contraindications of -sea point recorded in () and ( '), it is found that conception of -sea point of five- points has been specifically formed, the names of -sea points of eleven meridians, the locations and the ways to locate them were recorded. But, the summaries relevant to the indications of the many -sea points have not been included in teaching materials, thus, it needs to be further analyzed. The acupuncture-moxibustion techniques at -sea point are flexible and the attention should be paid to distinguish "needling -sea point in autumn" from "needling -sea point in winter". Besides, the consideration should be given on coma/fainting induced by arterial bleeding when needling -sea point, as well as the joint motor impairment caused by over deep insertion in acupuncture.
