The Large Intestine Meridian of Hand - Yangming starts from the tip of the index finger ( Shangyang, Li 1 ) . Running upward along the radial side of the index finger and passing through the interspace of the 1 ST and 2nd metacarpal bones ( Hegu, Li 4 ) , it dips into the depression between the tendons of m. extensor pollicis longus and brevis. Then, following the lateral anterior aspect of the forearm, it reaches the lateral side of the elbow. From there, it ascends along the lateral anterior aspect of the upper arm ( 5 ) to the highest point of the shoulder ( Jianyu Li 15 ) . Then, along the anterior border of the acromion it goes up to the 7th cervical vertebra ( the confluence of the three yang meridians of the hand and foot ) ( Dazhui, Du 14 ) , and descends to the supraclavicular fossa to connect with the lung. It then passes through the diaphragm and enters the large intestine, its pertaining organ. The branch from the supraclavicular fossa runs upward to the neck, passes through the cheek and enters the gums of the lower teeth. Then it curves around 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, to both sides of the nose ( Yingxiang, Li 20 ) , where the Large Intestine Meridian links with the Stomach Meridian of Foot - Yangming.Main indications: Acupuncture points in this meridian are indicated for diseases affecting the head, face, pharynx (throat), febrile conditions and other symptoms along the meridian pathway.Symptoms: Disharmony of the Large Intestine Meridian can lead to symptoms of abdominal pain, intestinal cramping, diarrhea, constipation and dysentery.
