Martial Applications & Effects of Injury:

One of the 36 vital points of Feng Yiyuan 馮一元 listed in the Wu Bei Zhi 武備志 (Treatise on Armament Technology) by Mao Yuanyi 茅元儀 (1621). Also listed in Article 21: Delayed Death Touches with Twelve-Hour (Shichen 時辰) Diagrams. This point, along with Shenting Du-24, Tianding LI-17, Shenque Ren-8 and Shenmai Bl-62, are associated with Chou 丑 Ox (1 - 3 am) and if struck during this time is said to cause death within 14 days from trauma to the anterior tibial artery and deep fibular nerve (McCarthy, 2016, Bubishi: The Classic Manual of Combat).

Striking this point causes so much local pain and Qi drainage right up to the forehead that the recipient feels disorientated (Montaigue, Dim Mak Locations, Taijiworld.com).


Major Combinations:


Zhou Yi Hexagram:

䷽ Xiao Guo 小過 Slight Excess & ䷏ Yu 豫 Enthusiasm.


As ䷏ Yu 豫 Enthusiasm:

Trigrams: Kun (Earth) below, Zhen (Thunder) above.

Receptivity within, movement without — thunder emerges from the earth. This is enthusiasm: the joy that arises when the people are moved by a leader they trust.

Nuclear Trigrams: Lines 2-3-4 form Gen (Mountain). Lines 3-4-5 form Kan (Water). Beneath the enthusiasm, there is stillness (Gen) and danger (Kan). The hidden message: enthusiasm must be grounded in stability and must navigate danger carefully. Joy without ground becomes chaos.

Judgement:
利建侯行師。
Beneficial to establish feudal lords and to set the army in motion.
It is advisable to recruit other points and channels to assist with the actions of this point. In particular, the Liver and Kidneys or Bladder (䷆ Shi 師 The Army: Jingmen GB-25 or Zhongji Ren-3) tend to work well together. The Kidneys provide reinforcement, while the Bladder is the Taiyang, the outer wall and home of Wei Qi, the soldiers for the General to direct.

Overall: Enthusiasm is the joy that arises when the people are moved. It is beneficial to establish structures and to direct that energy toward a purpose. Thunder emerges from the earth: the leader emerges from the people. The people follow willingly. This is the power of Yu.

Lines:

LineYin/YangImageLiteral TranslationClinical Reading
1 Yin 鳴豫,凶 Resounding Enthusiasm. Inauspicious. Xie Qi has only just started to settle at this point. Resorting to a strong point like this is premature and could drive it deeper.
2 Yin 介于石,不終日,貞吉 Firm as a rock. Not lasting the whole day. Burning is auspicious. Cold in the Liver channel causes swellings that are hard as a rock (疝 Shan disorder). Moxa can quickly alleviate.
3 Yin 盱豫,悔。遅有悔 Anxious enthusiasm. Remorse. Delay brings remorse. There is anxiety because the point cannot contain the Xie Qi, which will soon penetrate the rest of the channel, or the Zang organ directly. Harm is already done, and delaying it will bring more.
4 Yang 由豫,大有得。勿疑。朋盆簪 Following enthusiasm. Greatly obtaining. Do not doubt. Friends gather like a hairpin. The Zang starts to be affected, but can be saved by drawing on the resources of the Kidneys, which, together with the Liver, determines the health of head hair through the relationship between Blood and Jing. Water the mother of Wood.
5 Yin 貞疾,恆不死 Burning brings illness. Eternal and not dying. The Liver is generating a great heat, for which moxa here will only exacerbate. The Hun, the immortal part of the soul, is disturbed and restless.
6 Yin 冥豫,成有渝,無咎 Blind enthusiasm. Upon completion there is betrayal. No trouble. The inability to control the Xie Qi has led to the Liver invading other systems with blind enthusiasm for its military role. No trouble here is a request: the Liver must be sedated.

Image:
雷出地奮,豫。先王以作樂崇德,殷薦之上帝,以配祖考。
Thunder comes forth from the earth: Yu. Thus the former kings made music to honour virtue, and presented it lavishly to God, and to their ancestors.

Thunder bursts from the earth — the sound of enthusiasm. The former kings made music to honour virtue. They did not suppress the people's joy; they gave it form. Music is the perfect expression of Yu: it is structured, communal, and joyful. It is presented lavishly to God and the ancestors — enthusiasm is not just personal; it is offered upward.

Notes:

Main point for moving stagnation anywhere in the body and pacifying the Liver. Often reinforced with Hegu LI-4 to form the 4 gates.

It is noteworthy than the transverse Luo points which connect to these points, Guangming GB-37 and Lieque Lu-7, are the only two Luo whose longitudinal directions travel distal across the hands and feet.



The Su Wen Ch. 20, Discourse on the Three Sections and Nine Indicators, describes "The heaven [indicator] of the lower section: the foot ceasing yin [locations]... the heaven [indicator] serves to examine the liver". Wang Bing's commentary says this means "This is to say: the liver vessels. Their movement can be felt. it should be taken while the person lies down - at the 'five miles' section in the hollow one and a half inches below the Sheep Droppings (羊矢) [piercing hole] outside the [pubic] hair line" (Huang Di Nei Jing Su Wen, trans. Unschuld & Tessenow, 2011). Wang (2019, Daoist Internal Mastery) interprets this to mean Jimen Liv-12 or Zuwuli Liv-10. For women he suggests using this point. Wang et al. (2012) suggest that this was originally located at "upper surface of the great toe of the foot," where it is possible to feel the pulse of the first dorsal metatarsal artery.

Ling Shu Ch. 1, On the Nine Needles and the Twelve Origins, describes this point as the origin of the Shaoyang in the Yin.

Ling Shu Ch. 6 suggests piercing the Ying and Shu points of the Yin channels if a disease is in the Yin of the Yin realm. (e.g. the Zang organs) suggesting this point and Xingjian Liv-2 in diseases of the Liver.

Ling Shu Ch. 9, On Ends and Beginnings, advises that in the case of Heat associated with receding Yin Qi the Yang conduit should be pierced once and the Yin conduits twice. Based on other recommendation to use the He-Sea of the Yang conduits (Ch. 19) and the Yuan-Source with the Ying-Spring points (Chs. 6, 19 and 24) to clear Heat from the Zangfu, that would suggest this point, Yanglingquan GB-34 and Xingjian Liv-2 as a protocol to clear Heat in the Liver/Gall Bladder. Next it advises that in Cold associated with receding Yang Qi the Yang should be pierced twice and the Yin once but no such obvious protocol is evident for this situation. Another interpretation that would match with common practice today, based on the idea of odd numbers being Yang/moving/clearing while even numbers are Yin/tonifying/reinforcing, is that the points on the channel to be cleared are pierced on one side only while those on the channel to be tonified are pierced bilaterally.

Ling Shu Ch. 19, on the Four Seasonal Qi, advises using the Shu-Stream points, unless the diseases are in the Fu organs, in which case the He-Sea points are chosen.

Ling Shu Ch. 24, On Counterflow Diseases, employs the point combination mentioned in Ch. 6 for the treatment of Heart pain. It advises piercing this point and Xingjian Liv-2 when treating a Heart pain accompanied by ash-grey corpse-like complexion and inability to breathe deeply, associated with the Liver.

Ling Shu Ch. 44, On the Qi Moving in Accordance with the Norms, indicates that the Shu-Stream points should be pierced in summer or when the disease becomes milder and then more severe again. The seasonal aspect should not be interpreted literally as it describes the time periods of weakness and severity as "controlled by summer". It also describes the morning, afternoon, evening and night cycle of the day to be like the four seasons of the year with afternoon corresponding to summer.



Shang Han Lun, line 343, advises using moxa on Jueyin if a Jueyin pattern has lasted 6 or 7 days and is accompanied by faint pulse, reversal cold of the extremities, vexation and agitation. If it fails to restore the reversal the condition was considered fatal. Chang Qi-Zhi suggests this means using moxa on this point. Zhang Xi-Ju suggests Xingjian Liv-2 and Zhangmen Liv-13 (Mitchell, Ye and Wiseman, 1999, Shang Han Lun).



In Tung acupuncture the Huo Zhu (66.04), Fire Ruler, point is located 0.5 cun proximal to this point. It is indicated for Liver patterns with Heat presenting as cardiac, gastrointestinal, neurological or gynaecological disorders. It is often combined with Huo Ying (66.03), Fire Hard, 0.5 cun proximal to Xingjian Liv-2 (Chu, 2015; eLotus, 2022).



In early Chinese medicine, the pulse felt near the original location for this point, on the upper surface of the great toe of the foot (between Dadu Liv-1 and Xingjian Liv-2), was taken as an indication of the health of the Liver channel (Wang et al., 2012).



In reflexology this area relates to the breast, lung, chest and upper lymphatics.




Medieval phlebotomy point (John de Foxton, 1408: Liber Cosmographiae, maa.cam.ac.uk; Hans von Gersdorff, 1517: Feldtbüch der Wundartzney, www.nlm.nih.gov)



A Shokanten pulse is used to assist in diagnosis where the radial pulse is unclear, or in the comparative analysis of meridians in the upper and lower portions of the body. They are particularly used in psycho-emotional disorders. This point relates to the Upper Jiao, Taiyin and Liver.


In ayurvedic medicine:
Kurcha marma point

Structure: Tendon
Effect of Injury: Disability (vaikalyakar marma)
(Harish Johari, 1996, Ayurvedic Massage, Sanatan Society; Anupama Bhattacharya, n.d. Marma Shastra)



Sieler (2015,Lethal Spots, Vital Secrets,p.121) describes this point as titavarmam "sturdy vital spot" in Siddha martial arts which if injured causes the foot to swell, a blood clot to form and pain, which can be severe enough to cause unconsciousness.



In Tibetan medicine:
