The Foot-Jueyin (Liver) meridian originates at the lateral tuft of hair on the big toe (Dadun, LR1), ascends along the medial margin of the dorsum of the foot (passing Xingjian, LR2 and Taichong, LR3), one cun anterior to the medial malleolus (Zhongfeng, LR4), crosses behind the Foot-Taiyin (Spleen) meridian at eight cun above the ankle, continues upward along the medial aspect of the thigh (Qiquan, LR8), circles the external genitalia, enters the lower abdomen, flanks the stomach, belongs to the Liver, and connects with the Gallbladder. It ascends through the diaphragm, spreads in the hypochondriac region, follows the posterior aspect of the throat, enters the nasopharynx (Hangsang), connects with the eye system (Ocular system connecting to the brain), emerges above the forehead, and meets the Du vessel at the vertex. A branch descends from the eye system to the inner cheek, circling the interior of the lips. Another branch diverges from the Liver, pierces the diaphragm, and flows upward into the Lungs (where it transfers to the Hand-Taiyin Lung meridian).

When pathological changes occur in this meridian, symptoms include lumbar pain preventing flexion and extension, hernia in men, and distension of the lower abdomen in women. In severe cases, there is dryness of the pharynx, a dusty complexion, and loss of luster. This meridian governs diseases generated by the Liver: chest fullness, vomiting and counterflow qi, profuse watery diarrhea, fox hernia, urinary enuresis, and stranguria. In excess conditions, the Cun Kou pulse is larger than the Ren Ying pulse by one fold; in deficiency conditions, the Cun Kou pulse is smaller than the Ren Ying pulse (Ling Shu). At Chou hour (1:00-3:00 AM), Qi and Blood transfer from the Qiaoyin point of the Foot-Shaoyang (Gallbladder) meridian into Dadun (LR1) of the Foot-Jueyin (Liver) meridian, ascending along the knee and thigh to terminate at Qimen (LR14). The Jueyin meridian roots at Dadun (LR1), knots at Yuying, and links at Danzhong (RN17) (Ling Shu).

Dadun (LR1): Two points located at the tip of the big toe, approximately width of a leek leaf posterior to the nail corner, within the tuft of hair (Ru Men). Or in the tuft of hair on the big toe (Zi Sheng). As the Jing-Well point where the Qi of the Foot-Jueyin meridian arises, needle depth is 3 fen, retain for 6 breaths, moxibustion 3 moxa cones (Tong Ren).

Xingjian (LR2): Two points located at the arterial pulse between the first and second toes (Tong Ren). Or in the depression of the arterial pulse between the metatarsal bones of the adjacent toes (Ru Men). As the Ying-Spring point where the Qi of the Foot-Jueyin meridian flows, needle depth is 6 fen, retain for 10 breaths, moxibustion 3 moxa cones (Tong Ren).

Taichong (LR3): Two points located 2 cun posterior to the metatarsophalangeal joint of the big toe, in the Chong vessel (Tong Ren). Or at the arterial pulse 2 cun posterior to the base of the big toe (Zi Sheng). 2 cun superior to Xingjian (Ling Shu). As the Shu-Stream point where the Qi of the Foot-Jueyin meridian pours in, needle depth is 2 fen, retain for 10 breaths, moxibustion 3 moxa cones (Tong Ren).

Zhongfeng (LR4): Two points, also named Xuanquan, located in the depression 1 cun anterior to the medial malleolus (Tong Ren). Or on the oblique small vessel 1 cun anterior to the medial malleolus (Zi Sheng). As the Jing-River point where the Qi of the Foot-Jueyin meridian passes, take the position with the foot extended (Ling Shu). Needle depth 4 fen, retain for 7 breaths, moxibustion 3 moxa cones (Tong Ren). If located 1.5 cun anterior to the medial malleolus in the depression: reversing the foot causes the acupoint to be obstructed (Wan); harmonizing the foot allows flow (Tong). Shaking the foot locates the point. When the foot is reversed and extended, the point is depressed/closed; when harmonized, a channel opens. Hence, "Reverse leads to obstruction, Harmonize leads to flow" (Ling Shu).

Ligou (LR5): Two points, also named Jiaoyi, located 5 cun above the medial malleolus. As the Luo-Connecting point of the Foot-Jueyin Liver meridian, it diverges to the Foot-Shaoyang Gallbladder meridian. Needle depth 2 fen, retain for 3 breaths, moxibustion 3 moxa cones (Tong Ren).

Zhongdu (LR6): Two points, also named Zhongxi, located 7 cun above the medial malleolus, posterior to the tibia, aligned with the Foot-Shaoyin Kidney meridian. Needle depth 3 fen, moxibustion 5 moxa cones (Tong Ren).

Xiguan (LR7): Two points located 2 cun below Dubi (ST35), in the lateral depression. Needle inward, depth 4 fen, moxibustion 5 moxa cones (Tong Ren).

Qiquan (LR8): Two points located below the medial condyle of the tibia, between the large tendon and small tendon, in the depression. Take with the knee flexed (Tong Ren). Or in the depression at the apex of the transverse crease below the condyle (Ru Men). Sitting upright with knees flexed, in the depression between the medial and lateral tendons. Also described as at the head of the transverse crease when the knee is bent (Zi Sheng). As the He-Sea point where the Qi of the Foot-Jueyin meridian enters, needle depth 6 fen, retain for 10 breaths, moxibustion 3 moxa cones (Tong Ren).

Yinbao (LR9): Two points, also named Yinbao, located 4 cun above the knee, between two tendons on the medial aspect of the thigh. Needle depth 6 fen, moxibustion 3 moxa cones (Tong Ren).

Wuli (LR10): Two points located 3 cun below Qichong (ST30), at the arterial pulse in the medial thigh. Needle depth 6 fen, moxibustion 5 moxa cones (Tong Ren).

Yinlian (LR11): Two points located 2 cun below Yangzhu, in the arterial pulse. Needle depth 8 fen, retain for 7 breaths, moxibustion 3 moxa cones. Moxibustion here may induce pregnancy in nulliparous women (Tong Ren). Yangzhu (two points) is located 1 cun lateral to Qichong (Ru Men).

Zhangmen (LR13): Two points, the Front-Mu point of the Spleen, also named Changping or Xi'ao. Located lateral to Dahan (SP15), directly opposite the umbilicus (Tong Ren). Or 2 cun above the umbilicus, measuring 6 cun laterally, in the depression at the end of the costal margin while lying on the side (Ru Men). Directly opposite the umbilicus at the costal margin; lie on side, flex upper leg, extend lower leg, raise arm to locate (Gang Mu). 9 cun lateral to 2 cun above the umbilicus (Zi Sheng). Needle depth 6 fen, moxibustion 100 moxa cones (Tong Ren).

Qimen (LR14): Two points, the Front-Mu point of the Liver. Located 1.5 cun lateral to Burong (ST19), directly below the nipples at the second intercostal space (Tong Ren). Or directly below the nipples at the second rib end, 1.5 cun lateral. Also described as 1.5 cun below the nipple (Zi Sheng). Have the patient lie supine. Measure 5 cun vertically from the center of the umbilicus and mark with ink. Measure 2.5 cun horizontally from both sides of the mark. This is the correct location. Generally, use the distance between nipples as a reference with proportional measurement (Lei Ju Fang Guang Yi).
