一、大敦（井穴）
部位 在足大指之端及三毛之中也。
证治 卒心痛。汗出。腹胀肿满中热喜寐。五淋七疝。小便频数不禁。阴痛引小腹。阴
挺出。血崩尸厥如死。
针灸 针入一分。灸三壮。
按∶先师许公直 云。大敦在足大指端内侧。其肉敦阜。一般认大敦处为隐白。误
矣。凡伤寒病久。热入厥阴。刺大敦见血立效。考正穴法云。大敦足大指端。去
爪甲如韭叶及三毛中。盖三脉动于足大指。阳明在上。厥阴在中。太阴在下（俗
本太阴误作少阴）。阳明多气多血。与肝脾同会于足大指。故指上生丛毛。名曰
三毛。三毛之间非大敦穴。考足少阳脉交足厥阴。别跗上。入大指。出其端还贯
爪甲。出三毛。可证明经称三毛中。乃由足大指前之发端处达到三毛。经过大
指侧。肉起如敦状处是穴。穴在指端及三毛二者之中。名曰大敦。名实相副。继
起用针者。刺大敦多在足大指丛毛之间。浅刺之。误矣。

针灸 针入四分。灸三壮。
按∶中封乃足厥阴所行之经穴。各针灸书中皆云中封在足内踝前一寸。灵枢本输篇云
在内踝之前一寸半。盖灵枢根据骨度。凡言踝前后。踝上下。皆自踝骨中心起计
算。踝骨长一寸。中心至四旁骨际长半寸。继起用针尺度。除去踝中心至边际半
寸不算。故云一寸。所言不同。其部位仍同。穴在踝前陷中。两大筋所封闭。故
名中封。取穴时。仰其足则逆而宛。伸其足则和而通。摇其足则跗上两大筋分
开。其穴乃见。本输六十余穴。详言穴位字数最多者。惟此一穴。盖取之不易
也。（宛）音郁义亦同。

按∶曲泉乃足厥阴肝所入为合之水穴。水之高而有来源者。谓之泉。穴在内辅骨之下。
大筋之上。屈曲其膝乃能取得此穴。故曰曲泉。
一、大敦（井穴）
部位：位于足大趾的末端以及趾甲后丛毛之中。
证治：突发心痛。出汗。腹部胀满肿胀且内部发热，喜欢睡觉。五种淋证和七种疝气。小便频数且无法控制。阴部疼痛牵引至小腹。子宫脱垂。血崩及尸厥（一种类似死亡的昏厥状态）。
针灸：针刺深度一分。艾灸三壮。
按语：先师许公直说：大敦穴在足大趾端内侧，那里的肉厚实隆起。一般人误将大敦穴的位置认作隐白穴，这是错误的。凡是伤寒病日久，热邪传入厥阴经，针刺大敦穴见血立竿见影。考证正穴法记载：大敦穴在足大趾端，距离爪甲边缘如韭菜叶宽度的地方以及丛毛中。大概有三条经脉的气血搏动于足大趾处，阳明经在上，厥阴经在中，太阴经在下（俗本中将太阴误写为少阴）。阳明经多气多血，与肝脾二经同会于足大趾，所以脚趾上生长丛毛，称为“三毛”。三毛之间并非大敦穴。考证足少阳脉与足厥阴脉相交，别行于足背上方，进入大趾，从趾端出来贯穿爪甲，穿出丛毛。这可以证明经典所说的“三毛中”，是指由足大趾前端的发际处到达丛毛，经过大趾侧面，肉质隆起如土堆状的地方是穴位。穴位在大趾端和丛毛两者的中间，名为大敦，名实相符。后来使用针法的医者，针刺大敦多在足大趾丛毛之间，浅刺，这是错误的。
二、行间（荥穴）
部位：在足大趾和第二趾之间的缝隙后方五分处的动脉凹陷中。
证治：呕吐呃逆，咳血。心胸疼痛。腹部和胁肋胀满。面色青灰如同死状。中风。口眼歪斜。咽喉干燥，烦躁口渴。闭目不想看东西，眼中流泪。长叹气。癫疾，气短。肝积肥气。疟疾。腹泻不止，遗尿。小便不通，崩漏白带浑浊。寒疝。小腹痛，腰痛不能俯仰。小儿惊风。
针灸：针刺深度三分。艾灸三壮。
按语：行间是足厥阴肝经所流的荥穴。由大敦转入足大趾与足第二趾两指缝间。“彳”和“亍”合起来是“行”，两个脚趾相合，所以叫行间。
三、太冲（俞穴）
部位：行间穴向上二寸的凹陷中。
证治：虚劳呕血。恐惧，气不足。呕吐呃逆，发作时怕冷。肝疟。使人腰痛。咽喉干燥。胸胁支撑胀满。长叹气。浮肿。小腹胀满。腰部疼痛牵引少腹。脚冷或大小便困难。阴部疼痛，遗尿。大便稀溏，小便淋沥涩痛。小腹胀气。腋下马刀疡（瘰疬的一种）。脚踝酸痛。女子月经不通。漏血不止。小儿突发疝气。
针灸：针刺深度三分。艾灸三壮。
按语：太冲是足厥阴肝经所注的俞穴。肝脏藏血，女子太冲脉旺盛，则月经按时来潮。太冲又是九针十二原中的原穴。五脏禀受六腑水谷气味精华的通道，所以叫太冲。
四、中封（经穴）
部位：在内踝前方一寸半处，凹陷之中。使足内翻则气血郁滞不通，使足外伸则气血通畅。摇动足部即可找到。
证治：疟疾病人面色青灰如同死状。喜欢长叹气，发冷战栗。大便困难。小便肿痛。五种淋证。食欲不振。身体麻木不仁。寒疝痿厥。筋脉拘挛。失精，阴囊收缩入腹。相互牵引疼痛。或者身体微热。
针灸：针刺深度四分。艾灸三壮。
按语：中封是足厥阴肝经所行的经穴。各针灸书中都说中封在足内踝前一寸，《灵枢·本输》篇说在内踝前方一寸半。大概《灵枢》是根据骨度计算的，凡是说踝前后、踝上下，都是从踝骨中心开始计算。踝骨长一寸，中心到四周骨际长半寸。后来使用针法的度量标准，去除了踝中心到边际的半寸不算，所以说是一寸。说法不同，但部位仍然相同。穴位在踝前凹陷中，被两条大筋封闭，所以名叫中封。取穴时，仰起足则气血逆而郁滞，伸直足则气血和而通畅。摇动足部则足背上的两条大筋分开，穴位显现。《本输》六十余穴中，详细描写穴位字最多的，只有这一穴，大概是因为取穴不容易。（宛）音郁，意义也相同。
五、曲泉（合穴）
部位：在膝内侧辅骨的下方，大筋的上方。屈膝即可找到。
证治：疝气。大腿内侧疼痛。小便困难。气短。泄利脓血。腹部和胁肋支撑胀满。膝盖疼痛，筋脉拘挛。四肢不能抬起。不能屈伸。风劳失精。身体极度疼痛。膝盖和小腿发冷。阴茎疼痛。实证表现为身热，眼睛疼痛，无汗，眼睛视物模糊不清，发狂，流鼻血，气喘呼叫，疼痛牵引咽喉。女子子宫脱垂，小腹痛，阴部瘙痒，血瘕。
针灸：针刺深度六分。艾灸三壮。
按语：曲泉是足厥阴肝经所入为合的水穴。水源高且有来源的，称为泉。穴位在内辅骨的下方，大筋的上方。弯曲膝盖才能取得此穴，所以叫曲泉。
1. Dadun (Jing-Well Point)
Location: At the tip of the great toe and within the tuft of hair distal to the nail.
Indications & Treatments: Sudden heart pain. Sweating. Abdominal distension, swelling, and internal heat with a desire to sleep. Five types of strangury and seven types of hernia. Frequent urination with incontinence. Genital pain radiating to the lower abdomen. Uterine prolapse. Metrorrhagia and corpse-like syncope (a coma resembling death).
Acupuncture & Moxibustion: Puncture 0.1 cun. Moxibustion 3 moxa cones.
Commentary: My late teacher, Mr. Xu Zhizhi, stated that Dadun is located on the medial side of the tip of the great toe, where the flesh is thick and mound-like. It is a common error to mistake the location of Dadun for Yinbai. In cases of long-standing Shanghan disease where heat enters the Jueyin channel, puncturing Dadun until bleeding occurs yields immediate results. According to the verified acupoint methods, Dadun is at the end of the great toe, about the width of a leek leaf away from the nail corner and within the hair tuft. Generally, three meridians pulse at the great toe: Yangming is superior, Jueyin is intermediate, and Taiyin is inferior (in vulgar editions, Taiyin is erroneously written as Shaoyin). Yangming is abundant in Qi and Blood, meeting with the Liver and Spleen channels at the great toe; hence, tufts of hair grow on the toe, called "Sanmao" (Three Tufts). The area between the Sanmao is not Dadun. Examining the Foot-Shaoyang channel, it intersects with the Foot-Jueyin, branches onto the dorsum of the foot, enters the great toe, emerges from the tip, passes through the nail, and exits into the Sanmao. This proves that the classic's mention of "within the Sanmao" refers to the path from the anterior hairline of the great toe to the tuft, passing along the lateral side of the toe to the mound-like fleshy elevation. The point lies between the toe tip and the hair tuft, named Dadun, matching its name and reality. Later practitioners often puncture Dadun within the tufts of the great toe with shallow insertion, which is incorrect.
2. Xingjian (Ying-Spring Point)
Location: In the depression of the pulsating artery, 0.5 cun posterior to the web margin between the first and second toes.
Indications & Treatments: Vomiting, hiccups, and hemoptysis. Chest and heart pain. Abdominal and hypochondriac distension. A sallow complexion resembling death. Stroke. Facial paralysis. Dry throat, irritability, and thirst. Blepharoptosis with aversion to light, lacrimation. Sighing. Epilepsy and shortness of breath. Hepatic accumulation (Feiqi). Malaria. Profuse diarrhea and enuresis. Urinary retention, metrorrhagia, and leukorrhea. Cold hernia. Lower abdominal pain, lumbar pain with inability to flex or extend. Pediatric convulsions.
Acupuncture & Moxibustion: Puncture 0.3 cun. Moxibustion 3 moxa cones.
Commentary: Xingjian is the Ying-Spring point of the Foot-Jueyin Liver channel. It transitions from Dadun into the interdigital space between the first and second toes. "Xing" implies walking (composed of two halves meaning steps), and since the two toes meet, it is named Xingjian.
3. Taichong (Shu-Stream Point)
Location: In the depression 2 cun proximal to Xingjian.
Indications & Treatments: Consumption with hematemesis. Fearfulness and Qi deficiency. Vomiting, hiccups, and chills. Liver malaria. Lumbar pain. Dry throat. Hypochondriac fullness and distension. Sighing. Edema. Lower abdominal fullness. Lumbar pain radiating to the lower abdomen. Cold feet or difficulty in defecation and urination. Genital pain and enuresis. Loose stools and dysuria. Lower abdominal hernial qi. Scrofula (Madaoyang) in the axilla. Ankle soreness and pain. Amenorrhea in women. Persistent metrorrhagia. Acute pediatric hernia.
Acupuncture & Moxibustion: Puncture 0.3 cun. Moxibustion 3 moxa cones.
Commentary: Taichong is the Shu-Stream point of the Foot-Jueyin Liver channel. The Liver stores Blood; when the Taichong vessel is vigorous in women, menstruation arrives on time. Taichong is also the Yuan-Source point among the Twelve Original Points. It is the thoroughfare where the Five Zang organs receive the essence from the water and grain of the Six Fu organs; hence, it is named Taichong.
4. Zhongfeng (Jing-River Point)
Location: 1.5 cun anterior to the medial malleolus, in the depression. Turning the foot inward causes stagnation (Wan); extending the foot promotes flow. Shaking the foot reveals the point.
Indications & Treatments: Malaria with a sallow complexion resembling death. Frequent sighing and chills. Difficulty in defecation. Painful and swollen urination. Five types of strangury. Loss of appetite. Numbness of the body. Cold hernia and flaccidity. Tendon spasms. Seminal emission and retraction of the penis into the abdomen. Radiating pain. Low-grade fever.
Acupuncture & Moxibustion: Puncture 0.4 cun. Moxibustion 3 moxa cones.
Commentary: Zhongfeng is the Jing-River point of the Foot-Jueyin Liver channel. Most acupuncture texts state Zhongfeng is 1 cun anterior to the medial malleolus, but the *Ling Shu: Ben Shu* chapter states 1.5 cun. This is because *Ling Shu* is based on bone measurements; references to anterior/posterior or superior/inferior to the malleolus are calculated from the center of the malleolar bone. The malleolus is 1 cun long, and the distance from the center to the lateral edge is 0.5 cun. Later acupuncture measurement standards excluded this 0.5 cun central-to-edge distance, thus stating 1 cun. Although the descriptions differ, the location is the same. The point lies in the depression anterior to the malleolus, enclosed by two large tendons, hence named Zhongfeng (Middle Enclosure). When the foot is dorsiflexed, Qi stagnates; when extended, Qi flows smoothly. Shaking the foot separates the two large tendons on the dorsum, revealing the point. Among the sixty-plus points in *Ben Shu*, this point has the most detailed description regarding acquisition, indicating it is difficult to locate. ("Wan" is pronounced "Yu" and means the same.)
5. Ququan (He-Sea Point)
Location: Inferior to the medial condyle of the tibia and superior to the large tendon. Obtained by flexing the knee.
Indications & Treatments: Hernia. Pain in the medial thigh. Difficulty in urination. Shortness of breath. Dysentery with pus and blood. Hypochondriac and abdominal fullness. Knee pain and tendon spasms. Inability to lift the limbs. Inability to flex or extend. Wind-consumption and seminal emission. Severe body pain. Cold knees and shins. Penile pain. Excess patterns manifest as fever, eye pain, anhidrosis, blurred vision, mania, epistaxis, wheezing, and pain radiating to the throat. In women: uterine prolapse, lower abdominal pain, pruritus vulvae, and blood masses.
Acupuncture & Moxibustion: Puncture 0.6 cun. Moxibustion 3 moxa cones.
Commentary: Ququan is the He-Sea Water point of the Foot-Jueyin Liver channel. A water source that is high and has a distinct origin is called a "Quan" (Spring). The point is located below the medial tibial condyle and above the large tendon. Flexing the knee is required to access this point, hence named Ququan.
