There is also a branch, which goes up from the pelvic cavity to the neck, passes through the cheek, enters the lower gum, and then returns from the mouth, bypassing the mouth and lips. The left and right veins meet at a point in the middle of the human body. After crossing, the left pulse goes to the right, the right pulse goes to the left, and then goes up to both sides of the nostril, and the Xiang Ying point next to the nose is connected with the stomach meridian of Foot Yangming.

Lingshu Meridian: "The pulse of Yangming meridian in the large intestine refers to toothache and swelling of the neck, which is caused by body fluid, yellow eyes, dry mouth, sore throat, pain in front of the shoulder and pain in the thumb and fingers. Excessive qi leads to pulse heat and edema, while weak qi leads to chills. Therefore, all diseases are diarrhea, deficiency is tonic, heat is disease, cold is left, and depression is moxibustion. If it is not full, you can take it. " The pathological changes caused by exogenous pathogens invading meridians are toothache and neck swelling. Acupoints on the large intestine meridian of hand Yangming are mainly used to treat diseases with insufficient body fluid, the symptoms of which are yellow eyes, dry mouth, stuffy nose or nosebleeds, sore throat leading to air congestion, pain in front of shoulder and upper arm, and pain in index finger, which makes it impossible to move. The exuberance of qi is due to the fever and swelling of the parts where the meridians pass; When qi and blood in meridians are insufficient, symptoms such as chills and shivering will occur, and it is not easy to restore warmth. For these diseases, diarrhea is really used, and tonic is used for deficiency; Fast needling method is used for heat, and needle retention method is used for cold; Moxibustion is used for patients with pulse deficiency and depression, and the treatment is mainly meridian.
