The Gallbladder (Dan) is located between the short lobes of the Liver (Gan), and its primary function is to store bile without excreting it. For guiding herbs to this channel, Chai Hu (Bupleuri Radix) and Qing Pi (Citri Reticulatae Pericarpium Viride) are used. During the Zi hour (11:00 PM - 1:00 AM), Qi and Blood flow into the Gallbladder channel.
The Foot-Shaoyang Gallbladder Channel begins at the outer canthus (Ruizhi), ascends to the vertex/corner of the head, descends behind the ear, follows the neck to the shoulder, and enters the Clavicular Fossa (Quepen). A branch enters the ear from behind the ear, emerges anterior to the ear at the outer canthus, passes through the cheek, and joins the Clavicular Fossa. [Another branch descends to the lower jaw.] It descends through the chest, pierces the diaphragm, connects with the Liver, and belongs to the Gallbladder. It follows the hypochondrium and Qi Street, circles around the pubic hair area, and transversely enters the hip joint at the Huantiao point. The straight pathway descends from the Clavicular Fossa to the axilla, runs along the lateral aspect of the hypochondrium, and is sought along the lateral femur and the lateral auxiliary bone of the knee. [The high bone below the knee refers to the fibula; here it indicates the anterior aspect of the lateral fibula below the knee.] It descends to the Juegu (distal end of the fibula above the lateral malleolus) and passes anterior to the ankle. [Juegu refers to the upper border of the lateral malleolus/fibula.] It distributes between the fourth toe and the fifth toe. A branch from the dorsum of the foot enters the big toe, connecting with the Liver Channel at the Sanmao (three hairs) area. [Sanmao refers to the area posterior to the nail bed of the big toe.]
The Liver is located below the diaphragm, attaching superiorly to the ninth thoracic vertebra of the spine. Its meridians connect superiorly to the Heart and Lungs, and inferiorly it has no orifice. Liver Qi arises on the left side. For guiding herbs to this channel, Chai Hu, Qing Pi, Chuan Xiong (Ligustici Chuanxiong Rhizoma), and Wu Zhu Yu (Evodiae Fructus) are used. During the Chou hour (1:00 AM - 3:00 AM), Qi and Blood flow into the Liver channel.
The Foot-Jueyin Liver Channel terminates at the tip of the big toe in the cluster of hair, [i.e., the Sanmao area]. It follows the dorsum of the foot, passes above the medial malleolus, [along the medial margin of the medial malleolus], enters the pubic hair region from the medial thigh, [i.e., the pubic area], surrounds the external genitalia, reaches the lower abdomen, flanks the Stomach, belongs to the Liver, and connects with the Gallbladder. It ascends through the diaphragm, spreads in the hypochondrium, follows the throat and Hangsang (pharynx and nasopharynx), and travels with the Eye System. [Hangsang refers to the pharynx and nasopharynx. The deep interior of the eye is the Eye System.] It ascends to the forehead and reaches the vertex to meet the Du Meridian, [meeting the Du Meridian at the Baihui point on the vertex]. A branch returns from the Eye System, descends to connect with the inner cheeks and lips, [descending from the Eye System to the cheeks]. Another branch passes from the Liver through the diaphragm to connect with the Lung. [It again passes from the Liver through the diaphragm into the Lung. Straight pathways are called Jing (Channels), and branching pathways are called Luo (Collaterals). There are twelve Jing channels, comprising the Hand and Foot Yin and Yang channels. There are fifteen Luo collaterals, consisting of one collateral from each of the twelve channels, plus the large collateral of the Spleen, and the collaterals of the Ren and Du vessels, flowing like water. The Jing and Luo are the branches and leaves of the Zang-Fu organs, while the Zang-Fu are the roots of the Jing and Luo. Understanding the meridians allows for infinite adaptability. Thus, the classics state that the Jing channels determine life and death, manage all diseases, and regulate deficiency and excess; they must not be left unexamined.]
