By collecting and analyzing the explanation/conception, acupoint name, acupoint location, indications, acupuncture and moxibustion techniques and contraindications of he -sea point recorded in Neijing ( Inner Canon of Yellow Emperor ) and Nanjing ( Yellow Emperor ' s Classic of Eighty-one Difficult Issues ), it is found that conception of he -sea point of five- shu points has been specifically formed, the names of he -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 he -sea points have not been included in teaching materials, thus, it needs to be further analyzed. The acupuncture-moxibustion techniques at he -sea point are flexible and the attention should be paid to distinguish "needling he -sea point in autumn" from "needling he -sea point in winter". Besides, the consideration should be given on coma/fainting induced by arterial bleeding when needling he -sea point, as well as the joint motor impairment caused by over deep insertion in acupuncture.
