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.

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.
