Modern literature on the physical property of the yuan-source point were collected from Chinese National Knowledge Infrastructure(CNKI) and China Biology Medicine(CBM) databases. The physical property,relevant diseases and yuan-source acupoints were analyzed through statistical analysis of literature metrology. It is considered that articles on the electrical resistance of acupoint account for the largest part,which are mainly related to hyperthyreosis and the change of menstrual cycle. The second part is radiation spectrum,which are mostly relevant to the coronary heart disease and then the physiological change of healthy people. As to the diseases,articles of cardiovascular diseases are taken the most proportion,which were treated with the 12 yuan-source points,Shenmen(HT 7) and Daling(PC 7). Also,the results present the physical property of yuan-source acupoints in the yin meridians is more sensitive to diseases and the physical property is specific to diseases. Besides,the yuan-source acupoint can show the pathological changes of its own meridian.
