The Lung Meridian of Hand-Taiyin originates in the Middle Jiao (the area where the Spleen and Stomach are located), descends to connect with the Large Intestine, returns to follow the upper opening of the Stomach, pierces through the Diaphragm, and belongs to the Lung Organ. From the Lung System (tissues connected to the lung such as the trachea and throat), it emerges horizontally from below the axilla, descends along the medial aspect of the upper arm, running anterior to the Heart Meridian of Hand-Shaoyin and the Pericardium Meridian of Hand-Jueyin, descends into the cubital fossa, follows the medial aspect of the forearm, enters the Cun Kou (radial artery pulse point), ascends to the Thenar Eminence, follows the edge of the Thenar Eminence, and emerges at the tip of the thumb. Its branch arises from behind the wrist (at Lieque LU7) and goes straight to the medial border of the index finger, reaching its tip. When this meridian is affected by pathological changes, it manifests as Lung distension with a feeling of fullness and bloating, accompanied by wheezing and cough; pain in the Supraclavicular Fossa (Clavicular Fossa); and in severe cases, crossing both hands over the chest with blurred vision, known as Arm Jue. This meridian primarily governs diseases generated by the Lung, such as cough, Qi rebellion, wheezing, thirst, mental restlessness, chest fullness, pain or coldness in the anteromedial aspect of the arm, and heat in the palm. If Lung Qi is excessive, it presents with shoulder and back pain, sweating due to Wind-Cold invasion, stroke-like symptoms, frequent urination with small volume. If Lung Qi is deficient, it presents with shoulder and back pain with cold sensation, shortness of breath insufficient for respiration, and changes in urine color. In excess patterns, the Qi Kou pulse is three times larger than the Ying Yang pulse; in deficiency patterns, the Qi Kou pulse is smaller than the Ying Yang pulse.

The Luo-Connecting Point of the Lung Meridian of Hand-Taiyin is named Lieque (LU7). It originates in the interstices above the wrist, runs parallel with the Hand-Taiyin Meridian directly into the palm, and scatters into the Thenar Eminence. Its pathological manifestations include heat in the radial styloid process and palm in excess patterns, and yawning with urinary frequency or enuresis in deficiency patterns. Treatment involves selecting this point, located half cun distal to the wrist crease, which connects to the Yangming Meridian.

The Sinew Meridian of the Lung of Hand-Taiyin originates above the thumb, ascends along the finger, binds at the posterior aspect of the Thenar Eminence, runs on the lateral side of the Cun Kou, ascends along the forearm, binds at the elbow, ascends along the medial border of the upper arm, enters the axilla, emerges from the Supraclavicular Fossa, binds at the anterior shoulder, ascends to bind at the Supraclavicular Fossa, descends to bind in the interior of the chest, scatters and penetrates through the Diaphragm, and combines below the Diaphragm to reach the hypochondrium. Pathological changes involve stiffness and spasms at the sites traversed; severe pain may form Xi Ben (a type of accumulation disease characterized by subcostal mass, wheezing, and cough), hypochondriac rigidity, and hemoptysis. Treatment uses burning needle rapid puncture, taking symptom relief as the indicator, and using the painful point as the acupoint, named Zhongdong Bi. Lung diseases manifest as wheezing, cough, Qi rebellion, shoulder and back pain, sweating, and pain in the sacrum, yin region, thigh, knee, hip, and foot. Deficiency presents as shortness of breath with inability to take deep breaths, deafness, and dry throat. Select the Hand-Taiyin Meridian, as well as blood collaterals on the lateral side of the Foot-Taiyang Meridian and the medial side of the Foot-Jueyin Meridian. Lung Heat Disease initially presents with chills, piloerection, aversion to wind and cold, yellow tongue coating, and fever. During the struggle between pathogenic heat and healthy Qi, there is wheezing and cough, pain radiating to the chest and back, inability to take deep breaths, severe headache, sweating with chills. Symptoms worsen on Bing-Ding days and improve with profuse sweating on Geng-Xin days. If Qi rebels, death may occur on Bing-Ding days. Puncture the Hand-Taiyin and Hand-Yangming meridians to release blood amounting to soybean size, and recovery will be immediate.

The Lung Meridian of Hand-Taiyin travels from the abdomen to the hand, measuring three chi and five cun in length, totaling seven chi for both sides, with twenty-two acupoints.

Zhongfu (LU1) x2 (located in the third intercostal space above the nipple, where the artery is palpable, one cun from Yunmen LU2). Yunmen (LU2) x2 (located below Jugu GB21, two cun lateral to Qihu GB15, in the depression where the artery is palpable; select with arm elevated).

Prick with a three-edged needle to release a small amount of blood to drain heat from all Zang organs. Case: Cheng Junchuo, Prefect of Tang, suddenly developed swelling of the cheeks and jaw, throat obstruction, and inability to eat or drink for three days. Needling led to immediate recovery. Moxibustion is not suitable.

Regarding the Lung Meridian of Hand-Taiyin, it generally has abundant Qi and scarce Blood. Needling should aim to expel Qi and eliminate bad blood. Since the meridian travels from the Zang organs to the hand, one must carefully assess and follow the Qi flow. Excess is treated by reducing, deficiency by tonifying, heat by quick needling, cold by retaining the needle, sinking by moxibustion, and neither excess nor deficiency by treating according to the meridian itself. This is the method for treating the Hand-Taiyin Meridian.
