The lung meridian of hand-taiyin originates from the middle energizer, running downward to connect with the large intestine. Winding back, it goes along the upper orifice of the stomach, passes through the diaphragm, and enters the lung, its pertaining organ. From the lung system, which refers to the portion of the lung communicating with the throat, it comes out transversely. Descending along the medial aspect of the upper arm, it goes continuously downward along the anterior border of the radial side in the medial aspect of the forearm and enters cunkou. Passing the thenar eminence, it goes along its radial border, ending at the medial side of the tip of the thumb.
The branch proximal to the wrist emerges and runs directly to the radial side of the tip of the index finger and ends at the medial side of the tip of the index finger where it links with the large intestine meridian. (see Fig. 1-1)
Associated viscera: Lung, large intestine, stomach and middle energizer. Associated organs: Trachea and throat.
Disorders of the chest, lung, throat and the regions the meridian running by.
Commonly used acupoints
Yun means fog and cloud. Men means exit. It illustrates that Qi and blood exist in human body, originate from Zhongjiao, gather in Zhongfu, leave Yunmen, as cloud flows in the sky, multiply everything.
Location: In the superior lateral part of the anterior thoracic wall, anodic scapula, infraclavicular fossa introcession, 6 cun lateral to the anterior midline.
Locating Methods: The patient sits straight with hands against waist. In the middle of the depression between the acromion and the humerus.
Acupoint in anatomy: skin, subcutaneous tissue, triangular muscle, coracoclavicular fascia, coracoid process. Skin contains clavicle intermediate branch and lateral branches nerve supply. Besides all that have mentioned above, cephalic vein nerve cross subcutaneous tissue. The acupuncturist stabs from skin, cephalic vein and coracoclavicular fascia, to coracoid process of scapula.
Needling and Moxibustion Methods
Needling and moxibustion
a. Needling: oblique needling outwards 0.5-10.1 cun. Needling feeling: partially aching sweling spreads to protothorax and armpit. When doing needling, acupuncturist should not stab inside deeply to avoid cutting lung, leading pneumothorax.
b. Moxibustion: moxa cone 3-7 zhuang, moxa stick for 5-15 minutes.
Function and indication:
Function: regulate lung- Qi, relieve pain and stop coughing
1.Disease of respiratory system, cough, asthma, thoracalgia.
2.Others: shoulder pain, omalgia
3.hypersensitiveness and tenderness in disease of lung and bronchus.
Cautions: when needling in Yunmen, acupuncturist should not stab axillary vein and cephalic vein. If acupuncturist stabs inwards, axillary vein would be hurt. If acupuncturist stabs towards clavicle inferior border, cephalic vein would be hurt. If acupuncturist stabs deeply inside to thoracic cavity, pleura would be broken. In anatomical point of view, it is best to press cephalic vein with one finger inwards, and then stab along the margo medialis scapulae next to margin of the subclavian piercing. It can be safe that acupuncturist leaves needles in the direction of vertical or slightly toward the outside. It is not allowed that acupuncturist stabs deeply inwards, leading lung injury and pneumothorax.
