The Large Intestine Meridian of Hand-YangMing begins at the tip of the index finger). It runs upwards along the radial aspect of the index finger and passing through the interosseous space of the 1st and 2nd metacarpal bones Hegu(LI 4) where it enters the depression between the tendons of extensor pollicis longus and brevis. Then, it runs along the anterior aspect of the forearm until it reaches the lateral aspect of the elbow. From there, it ascends along the posterio-lateral aspect of the upper arm to the highest point of the shoulder Jianyu(LI 15). At the anterior border of the acromion, it ascends to the 7th cervical vertebra (the confluence of the three yang meridians of the hand and foot Dazhui(GV14); it then descends to Quepen(ST12) (in the supraclavicular fossa) to connect with its corresponding zang-fu organ. Finally, it then passes through the diaphragm and enters the large intestine, its associated organ. The branch from Quepen(ST12) runs upwards to the neck, passes through the cheek and enters the lower gums. Then it turns back to the upper lip and crosses the opposite meridian at the philtrum. From there, the left meridian goes to the right and the right meridian to the left, on the opposite sides of the nose Yingxiang(LI 20), where the Large Intestine meridian links with the Stomach Meridian of Foot- YangMing.
Points on the Large Intestine meridian of Hand-Yangming The first point of the meridian is Shangyang (LI 1) and last one is Yingxiang (LI 20). There are 20 points on each side.
