The Eight Confluent Points of the Extra Meridians
These points are where the eight extra meridians meet the twelve regular meridians. They are located around the wrist and ankle regions. Since the extra meridians meet the regular meridians at definite acupoints, acupuncture and moxibustion on these acupoints help to treat diseases of the regions that they commonly regulate. During application, practitioners often select two points, one is on the arm and the other is on the leg, and also from alternative sides for stimulation.
