Skin-subcutaneous tissue-trapezius muscle-inferior border of rhomboid muscle-erector spinal muscle.
In the superficial layer, there are the medial cutaneous branches of the posterior branches of the 5th and 6th thoracic nerves and the accompanying arteries and veins. In the deep layer, there are the muscular branches of the posterior branches of the 5th and 6th thoracic nerves and the branches or tributaries of the dorsal branches of the related posterior intercosral arteries and veins.
Lie prostrate; at the level of the lower border of spinous process of the 5th thoracic vertebra, 1.5 cun apart from ShendaoGV11(Shendao (GV11)) laterally.
Restoring menstrual flow, regulating qi and blood, and relieving mental stress.
Coronary heart disease, angina cordis, rheumatic heart disease, artrial fibrillation, tachycardia, neurasthenia, intercostal neuralgia, schizophrenosis, epilepsy, hysteria, gastrorrhagia, vomiting, esophagostenosis, carbuncle and phlegmon.
Combined use with NeiguanPC6 (Neiguan (PC6) Luo-Connecting Point the Eight Confluent Point) for treatment of angina cordis and tachycardia; with JueyinshuBL14 (Jueyinshu (BL14)), ShenzhuGV12 (Shenzhu (GV12)), ShendaoGV11 (GV11), ZhiyangGV9 (Zhiyang (GV9)) for treatment of arrhythmia; with NeiguanPC6 (PC6), ZusanliST36 (Zusanli (ST36) He-Sea Point) for treatment of rheumatic heart disease, with BaihuanshuBL30 (Baihuanshu (BL30)) fortreatment of spermatorrhea; and with JuqueCV14 (Juque (CV14) Front-Mu Point of the Heart) for treatment of epilepsy.
Insert the needle horizontally 0.5-1 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.
