1. Zhiyin (Jing-Well Point)
Location: On the lateral side of the little toe, at a distance from the nail margin equivalent to the width of a leek leaf.
Indications: Opacity of the eye (cataract/pterygium). Nasal congestion with heavy head. Wind-cold pathogen initiating from the little toe. Mai-bi (pulse obstruction) spreading up and down. Chest and hypochondriac pain with variable locations. Muscle spasms (tetany). Cold malaria. Anhidrosis. Vexation in the heart. Heat in the soles of the feet. Dysuria.
Acupuncture and Moxibustion: Needle insertion depth is 2 fen. Moxibustion: 3 moxa cones.
Commentary: Zhiyin is the Jing-Well Metal point of the Foot-Taiyang Bladder Meridian. Examining the sequence of the twelve meridians' circulation, the Foot-Taiyang meridian terminates at this point and connects to the Foot-Shaoyin Kidney Meridian. Since the Taiyang meridian points connect to the Yin meridians here, it is named "Zhiyin" (Reaching Yin).
2. Tonggu (Ying-Spring Point)
Location: In the depression anterior to the proximal interphalangeal joint on the lateral side of the little toe.
Indications: Heavy head and vertigo. Susceptibility to fright. Rhinorrhea or epistaxis. Neck and nape pain. Visual blurriness.
Acupuncture and Moxibustion: Needle insertion depth is 2 fen. Retain needle for three breaths. Moxibustion: 3 moxa cones.
Commentary: Tonggu is the Ying-Spring point where Qi flows through in the Foot-Taiyang meridian. "Xing" refers to small streams, and "Gu" implies the passage of small waters; hence, it is named Tonggu.
3. Shugu (Shu-Stream Point)
Location: Posterior to the proximal interphalangeal joint on the lateral side of the little toe, in the depression at the junction of red and white skin.
Indications: Low back and spine pain as if broken. Inability to flex the thigh. Stiffness as if bound. Sensation of tearing. Deafness. Aversion to wind and cold. Vertigo. Stiff neck unable to look back. Redness and ulceration of the inner canthus.
Acupuncture and Moxibustion: Needle insertion depth is 3 fen. Moxibustion: 3 moxa cones.
Commentary: Shugu is the Shu-Stream point where Qi is infused in the Foot-Taiyang meridian. Anteriorly lies the bone of the little toe's proximal joint, and posteriorly lies the large bone above the Jinggu point. This point resides in the depression at the junction of red and white skin on the lateral side. The anterior proximal joint bone and the posterior large bone resemble a state of being constrained, hence the name Shugu (Bound Bone).
4. Jinggu (Yuan-Source Point)
Location: Below the large bone on the lateral aspect of the foot, in the depression at the junction of red and white skin.
Indications: Knee pain with inability to flex or extend. Redness and ulceration of the inner canthus. Malaria with alternating chills and fever. Susceptibility to fright. Anorexia. Tendon contraction. Soreness and weakness of the feet. Pain in the hip pivot. Neck stiffness. Inability to bend or extend the waist and back. Persistent epistaxis. Vertigo.
Acupuncture and Moxibustion: Needle insertion depth is 3 fen. Moxibustion: 7 moxa cones.
Commentary: Jinggu is the Yuan-Source point where Qi passes through in the Foot-Taiyang meridian. "Jing" means great. This point is located below the large bone on the lateral foot. This large bone was originally named Jinggu; because it shares the name with the acupoint, the bone was separately referred to as "Da Gu" (Great Bone), similar to how the wrist bone is separately called "Qi Gu". The principle is the same.
5. Kunlun (Jing-River Point)
Location: Posterior to the lateral malleolus, in the depression above the calcaneus.
Indications: Pain in the lower back and buttocks. Swelling of the foot making it impossible to touch the ground. Rhinorrhea or epistaxis. Stiffness as if bound. Sensation of ankle tearing. Headache with rigidity of shoulders and back. Sudden cough, wheezing, and fullness. Swelling and pain of the yin region. Pediatric epilepsy with convulsions.
Acupuncture and Moxibustion: Needle insertion depth is 5 fen. Moxibustion: 3 moxa cones, size of a wheat grain. Caution: Needling this point may cause abortion in pregnant women.
Commentary: Kunlun is the Jing-River point where Qi flows along in the Foot-Taiyang Bladder Meridian. The Bladder is the mansion of water. This point is located posterior to the malleolus, higher than the Jing-Well, Ying-Spring, Shu-Stream, and Yuan-Source points. Kunlun represents the high source of water, hence the name of the point.
6. Weizhong (He-Sea Point)
Location: In the depression of the arterial pulse at the center of the popliteal crease. Position the patient prone with face down to locate the point.
Indications: Knee pain. Heaviness in the lumbar region flanking the spine. Enuresis. Heavy waist unable to lift the body. Bi-syndrome due to wind. Hip pivot pain, treatable by bloodletting. All chronic rashes will be cured. For any Shanghan (cold damage) with fever and anhidrosis, taking blood from this meridian leads to immediate recovery. Weizhong is the Xue-Xi (Blood Cleft). For severe wind disease causing eyebrow loss, bloodletting at this point is indicated.
Acupuncture and Moxibustion: Needle insertion depth is 8 fen. Retain needle for three breaths. Reduce method: seven inhalations. Contraindication: Moxibustion is prohibited.
Commentary: Weizhong is the He-Sea point where Qi enters in the Foot-Taiyang Bladder Meridian. The point is in the center of the popliteal fossa; one bends and takes it, hence the name Weizhong. For conditions along the Foot-Taiyang meridian involving heaviness and pain in the waist, hips, and knee joints, eyebrow loss due to severe wind, or wind pathogens deeply entering the Yang Qiao vessel (a collateral branch of the Foot-Taiyang), bloodletting at Weizhong is applicable. The aforementioned conditions are all excess patterns suitable for reduction methods. For deficiency patterns, needling should not be done recklessly. The Suwen states: Needling the large vessels at Weizhong may cause collapse and pallor; this must be known.
