The human body has a symmetric structure and maintains a physiological balance through the harmony of yin and yang. One of the fundamental principles of acupuncture is that unbalanced or abnormal bioenergetic conditions on the left and right meridians may be restored to a balanced, normal condition by acupuncture therapy. In this study, the electrical potential along the stomach meridian was measured to investigate the bioenergy consensus between the operator and subject during acupuncture stimulation, and the acupuncture response on opposite meridians was investigated by comparing the electric potential on the left and right stomach meridian during stimulation of the left side stomach meridian-36. When meridian electrical potential was simultaneously measured in both the operator and subject, opposite polarities were observed, which might indicate the transfer of bioenergy between operator and subject. In addition, the meridian electrical potentials of the subjects' left and right stomach meridians were also always of opposite polarity and presented three different signal patterns, which might have represented the condition of the associated meridian.
