The acupuncture has been known to induce the changes is not only needling part but also other parts distant from needling part.
The histlogical or physiological changes observed in the skin of needling locus have been reported but the changes on the distant part from needling locus have not been known.
In the present study, the changes is skin tempreture on epigastrium “hsin hsia pi” (stagnancy under under the hert) caused by needling on loci Left S36, Right S36, Left P6, Right P6, Left LI4, Right LI4, and Right Liv 8 were observed by Thermal Video System.
The needling on the these loci induced the increase of skin tempreture in epigastic region. In addition, the needling on Left S36 was most effectve the increase the skin tempreture in epigastic region, and the increasing tempreture was 0.5°C.

To demonstrate acupunctural effects on remote areas of the human body, a needle was held stationary at l-Lv-8 and the changes in skin temperature were measured at the location of the congested-blood syndrome in the left hypogastric region, using a skin thermometer and a thermal video system. The acupuncture caused the temperature to rise from a level lower than in the normal state. As a control, healthy persons were treated in the same manner, but no appreciable change was observed.
With a patient having congested-blood syndrom in the left hypogastric region, the l-Lv-8 point was tender to the touch. This was not the case with healthy persons.
It has thus been demonstrated that a stationary insertion at an abnormal point has an effect on the specific, remote location where the abnormal condition exists.
Only one insertion at an abnormal point has proven effective.
