The lung is shaped with four corners hanging downwards, attached to the third thoracic vertebra of the spine. It contains twenty-four hollow spaces arranged in rows and columns to circulate the Qi of all Zang and Fu organs. The Lung is the chief of the Zang organs and acts as a canopy (Hua Gai) for the Heart. The lung lobes are white and translucent, hence called the "Canopy" because they cover and protect the other organs. Its interior is vacuous like a honeycomb, with no open orifices at the bottom; it fills upon inhalation and becomes empty upon exhalation. With each breath, the movement of Qi is natural, governing the transformation and transportation of clear and turbid substances, serving as the bellows of the human body. For guiding herbs to specific meridians (Yin Jing Bao Shi), Shengma (Cimicifugae Rhizoma), Baizhi (Angelicae Dahuricae Radix), Jiegeng (Platycodonis Radix), and Congbai (Allii Fistulosi Bulbus) are used. During the Yin hour (03:00-05:00), Qi and Blood flow into the Lung.
The Hand-Taiyin Lung Meridian originates from the Middle Jiao, [starting at the Zhongwan point of the Stomach]. The three Yin meridians of the hand travel from the Zang organs to the hands. [It] descends to connect with the Large Intestine and returns to the贲门 (Bimen, cardia). [In this meridian, it is called Mai (vessel); in other meridians, it is called Luo (collateral)]. Ascending through the diaphragm, it belongs to the Lung and connects with the Lung system, [i.e., the trachea and larynx]. It emerges horizontally from the axilla and travels inward, [the area above the ribs is called the axilla; inward refers to the medial side of the arm. Generally, Yang meridians run on the exterior, while Yin meridians run on the interior]. It passes through the elbow, forearm, Cun Kou (inch position/radial artery), and ascends to Yu Ji (Lung 10), [Cun Kou refers to the arterial pulse point. Yu Ji refers to the fleshy eminence at the base of the thumb]. It terminates at the inner edge of the nail root of the great toe. A branch separates from behind the wrist, [branches are like twigs on a tree], travels to the inner edge of the index finger, and connects with the Yangming Meridian. [The twelve meridians circulate Ying (Nutritive) Qi, thus it is said that Ying Qi flows within the vessels. The Lung is mentioned first because the Lung governs all vessels. Following the sequence, after each meridian has completed its course, the cycle restarts and returns to the Lung, completing one full circulation].
The Large Intestine, also known as the Hui Chang (Coiled Intestine), is located at the umbilicus, looping leftwards sixteen times. The Guang Chang (Broad Intestine) attaches to the spine, receiving the Hui Chang, serving as the pathway for expelling waste and filth. It is called Hui Chang because of its coiled and folded structure. The Guang Chang is the larger portion of the Hui Chang, and the Zhi Chang (Rectum) is the terminal segment of the Guang Chang. It connects inferiorly to the anus, which is called Gu Dao (Valve Pathway) or Hou Yin (Posterior Orifice), also known as Po Men (Gate of the Corporeal Soul); collectively, these belong to the Large Intestine. The upper opening of the Large Intestine is the lower opening of the Small Intestine. For guiding herbs, Shengma (Cimicifugae Rhizoma), Baizhi (Angelicae Dahuricae Radix), and Shigao (Gypsum Fibrosum) are used. During the Mao hour (05:00-07:00), Qi and Blood flow into the Large Intestine.
The Hand-Yangming Large Intestine Meridian and the Large Intestine begin at Shang Yang (LI 1), [an acupoint located on the radial side of the index finger]. The three Yang meridians of the hand travel from the hands to the head. [It] follows the radial border of the finger, emerges at He Gu (LI 4), [He Gu means Tiger's Mouth, a common name for LI 4], between the two tendons of the bifurcation of the metacarpal bones, follows the lateral aspect of the forearm, [along the upper lateral border of the arm], enters the lateral aspect of the elbow, follows the anterior lateral border of the upper arm, [anterior lateral border of the humerus], passes anterior to Jian Jing (GB 21), beside Tian Zhu (BL 10), [Tian Zhu refers to the cervical vertebrae at the root of the neck]. From the shoulder, it enters below the collarbone (Que Pen), connects with the Lung, crosses the diaphragm, and belongs to the Large Intestine. A branch rises from Que Pen, enters the neck, obliquely crosses the cheek, descends into the lower gums, circles out to Ren Zhong (GV 26), crosses left and right, ascends to flank the nostrils, and injects into Ying Xiang (LI 20). [Ying Xiang is an acupoint, named for the crossing of meridians above the nostrils].
