Skin-subcutaneous tissue-trapezius muscle-rhomboid muscle-superior posterior serratus muscle-erector spinal muscle.
In the superficial layer, there are the medial cutaneous branches of the posterior branches of the 3rd and 4th thoracic nerves and the medial cutaneous branches of the dorsal branches of the accompanying posterior intercostal arteries and veins. In the deep layer, there are the muschlar branches of the posterior branches of the 3rd and 4th thoracic nerves and the branches or tributaries of the related posterior intercostal and veins.
Lie prostrate; at the level of the lower border of spinous process of the 3rd thoracic vertebra, 1.5 cun apart from ShenzhuGV12(Shenzhu (GV12)) laterally.
Regulating the lung qi, clearing away the heat of deficiency type, and regulating the nutrient and blood.
Cough due to exopathy, pulmonary tuberculosis, pneumonia, pneumorrhagia, bronchitis, asthma, pleuritis, endocarditis and epicarditis, spontaneous perspiration, night sweating, cutaneous pruritus, stomatitis, acid regurgitation, lumbago, and infant dystrophia.
Combined use with TiantuCV22 (Tiantu (CV22)) for treatment of bronchitis; with QuchiLI11 (Quchi (LI11) He-Sea Point) for treatment of cutaneous pruritus; with ChizeLU5(Chize (LU5)He-Sea Point) for treatment of pneumonia; with LiequeLU7 (Lieque (LU7)Luo-Connecting Point the Eight Confluent Point) for the treatment of whooping cough; with GaohuangBL43 (Gaohuang (BL43)) for treatment of infiltrative pulmonary tuberculosis; with DushuBL16 (Dushu (BL16)), PishuBL20 (Pishu (BL20)), FenglongST40(Fenglong (ST40) Luo-Connecting Point), ZhongwanCV12 (Zhongwan (CV12) Front-Mu Point of the Stomach), QihaiCV6 (Qihai (CV6)), ZusanliST36 (Zusanli (ST36) He-Sea Point) for treatment of bronchiectasis.
Insert the needle horizontally 0.5-0.8 cun deep; needling response: local numbness and distension; moxibustion: using 3-5 moxa-cones, or mild moxibustion for 10 min.
Don`t puncture deeply, or else the needle would penetrate the transversospinal muscle-the external intercostal muscle-the internal intercostal muscle-the parietal pleura-the pleural cavity-the visceral pleura and the lung by its tip, and cause an injury to lung tissue, leading to pneumatothorax.
