Front Mu of the Gall Bladder
Trigger point (Travell & Simons, 1998, Trigger Point Manual)
Meeting of Gall Bladder with Spleen, Gall Bladder Divergent and Liver Divergent
On the anterior chest wall, in the seventh intercostal space, directly below the nipple, 4 cun lateral to the midline.
Transverse-oblique insertion along the intercostal space 0.5 - 1 cun
Deep or perpendicular needling may induce a pneumothorax.
"The Shaoyang usually has little Blood and much Qi" (Su Wen 素問 ch. 24) implying this channel should normally be needled.
"The foot Shaoyang is to be pierced 4 fen deep and remain inserted for five exhalations" (Ling Shu 靈樞 ch. 12).
"It is needled to a depth of seven fen and moxaed with five cones" (Huangfu Mi 皇甫謐, 3rd Century, Zhenjiu Jiayi Jing 針灸甲乙經).
Benefits the Gallbladder and spreads Liver Qi
Lowers rebellious Qi and harmonises the Middle Jiao
Resolves Damp Heat
Hexagram attributions are my own with an explanation given in the glossary.

In seizing martial arts (Qin Na) this point is a cavity press point (Dian Xue, 點穴) struck with, fist, Phoenix Eye Fist, elbow, side of the foot or heel causing possible sealing of the breath and liver shock or rupture (Yang, 1995, Tai Chi Chin Na).
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 9: Twelve-Hour (Shichen 時辰) Vital Points Revealed as the vital point associated with the Zi 子 Rat (11 pm - 1 am) and the Gallbladder meridian (McCarthy, 2016, Bubishi: The Classic Manual of Combat).
Struck hard this point can cause death, or knock out if only struck medium (Montaigue, Dim Mak Locations, Taijiworld.com).
This is one of the eight striking points in Northern Praying Mantis Kung Fu. These are the nonfatal areas on an attacker's body that can be struck when just defending or wanting to defeat an attacker. Although described as "The point in the middle of the ribs" the diagram shows it towards the bottom of the sternum, around Ren-16 (Olson, 2010, The Complete Guide to Northern Praying Mantis Kung Fu). However, Wong Honfan (1946) describes it as "the lungs under the upper ribs [the flanks]" suggesting that it may mean in between the ribs on the flanks at this point or Liv-14 (Ravenswood Academy, 2020, The Eight Forbidden Strikes of Praying Mantis Fist).
Near to this point, just below the costal margin on the right side, is where to elicit Murphy's sign as a test for gallstones. Placing a hand here during exhalation and asking the patient to inhale will push the gallbladder against the examiners fingers and elicit a reaction if tender. To confirm pain must not be elicited on the left side too.
The image of this points name, "Sun-Moon," suggests the unification of Yin and Yang, and the pivoting and harmonising properties of the Shaoyang meridians. It may also refer to the influence of the Gall Bladder on the Curious Organs which are also places where the Shen and Jing combine to generate consciousness (Jingshen).
The Front Mu points make likely locations for application of leeches to reduce fevers according to François Broussais' (1772-1838) philosophy who believed in placing them over the diseased organs to reduce inflammation (Greenstone, 2010, The history of bloodletting, BCMJ, Vol. 52, No. 1, Pp 12-14).
Lad and Durve (2008) in Marma Points of Ayurveda locate two point with different names and functions on the left and right between here and Fuhai Sp-16, directly below the nipple on the costal margin. Both are associated with the doshas: Ranjaka Pitta, Pachaka Pitta, Samana Vayu, Apana Vayu and Kledaka Kapha.
The point on the right side is called Yakrut has the following functions:
- Regulates the function of the liver and gallbladder
- Stimulates bhuti agni (liver metabolism) and detoxifies ama
- Regulates digestion and metabolism of all seven dhatus (tissues)
- Regulates functions of small intestine and colon
- Relieves pain locally
- Pacifies fiery emotions
The point on the left side is called Pliha and has the following functions:
- Regulates spleen functions
- Regulates and detoxifies blood
- Enhances immunity
- Enhances lymphatic circulation
- Regulates functions of small intestine and colon
- Relieves pain locally
- Balances emotions
Basic information on location, needle depth, TCM actions, indications and combinations is taken from Deadman et al (2001): A Manual of Acupuncture with additional anatomical information researched by reference to Gray's Anatomy (38th Ed., 1995) unless otherwise referenced. Images were found on acupunctureschoolonline.com and can be traced back to Claudia Focks (2008) Atlas of Acupuncture originally. I cannot claim any credit or rights over them.
