GB-13 (Ben Shen) Root Spirit

What does GB-13 Ben Shen do?

Ben Shen GB-13 sits on the forehead just inside the hairline, on the Gall Bladder channel of Foot Shao Yang, and it is one of the small group of points the tradition reaches for when the presenting problem is of the mind rather than of the body. Its name says so outright: ben shen, "root of the spirit". Sacred Lotus sources & references record it as a Meeting Point of the Gall Bladder channel with the Yang Linking Vessel (Yang Wei Mai), and its recorded action is to eliminate wind, resolve phlegm and treat epilepsy.

• Eliminates wind and resolves phlegm — the recorded action in our own data. In Chinese medicine "phlegm misting the orifices of the heart" is the standard explanation for clouded, confused or disordered mental states, and internal wind for the convulsive ones; a point credited with both is therefore a point for the seizure-and-confusion territory rather than for coughing up sputum.
• Treats epilepsy and convulsion — named explicitly in our own action record, and the use for which the point is best documented in the classical literature.
• Calms the spirit — the action the name announces and the reason GB-13 appears in classical prescriptions for insomnia, fright, agitation, anxiety and the disordered mental states the tradition groups under "mania and withdrawal".
• Benefits the head and clears the channel locally — for headache across the forehead, dizziness, stiffness of the neck, and pain and heaviness of the head, which is what a point on the forehead is most often used for in ordinary practice.

Why does the Yang Linking Vessel connection matter?

The Yang Linking Vessel (Yang Wei Mai) is one of the eight extraordinary vessels. Unlike the twelve channels it has no points of its own; it is defined entirely by the points at which it meets them. Its role, as the name says, is to link the yang channels — to bind the exterior and yang aspect of the body together — and it is classically associated with alternating chills and fever, with the side of the head, and with disorders that move between the surface and the interior.

Our own holdings record seventeen points as meeting or governing this vessel, and they form a recognisable pattern: a large block along the Gall Bladder channel of the head (GB-13 Ben Shen, GB-14 Yang Bai, GB-15 Tou Lin Qi, GB-16 Mu Chuang, GB-17 Zheng Ying, GB-18 Cheng Ling, GB-19 Nao Kong, GB-20 Feng Chi) plus GB-21 Jian Jing at the shoulder; DU-15 Ya Men and DU-16 Feng Fu at the base of the skull; SI-10 Nao Shu, SJ-13 Nao Hui and SJ-15 Tian Liao around the shoulder blade; BL-63 Jin Men and GB-35 Yang Jiao, the latter being the vessel's Xi-Cleft point, on the leg; and SJ-05 Wai Guan at the wrist, which is its Confluent point — the point through which the whole vessel is classically opened. GB-13 is therefore the most forward, most frontal member of a vessel that runs the entire yang surface of the body, and the only one of the head group whose name concerns the spirit.

What is GB-13 Ben Shen used for?

Ben Shen GB-13 is used for epilepsy and convulsion, for mental-emotional disturbance, and for headache, dizziness and insomnia. The indications carried in Sacred Lotus sources & references are headache, insomnia, vertigo and epilepsy; the standard reference literature sets them out more fully below. These describe traditional use, not proven treatment.

• Epilepsy and convulsion
• Infantile convulsion
• Insomnia and disturbed sleep
• Headache, particularly across the forehead
• Vertigo and dizziness
• Anxiety, agitation and fright
• Mania and withdrawal (the classical category for disordered mental states)
• Poor memory and difficulty concentrating
• Rigidity and pain of the neck
• Pain and swelling of the eye; blurred vision
• Nasal congestion and nosebleed
• Hemiplegia and the sequelae of windstroke
• Vomiting of foamy saliva (recorded in the classical texts alongside the epilepsy indication)

Where is GB-13 Ben Shen, and how is it used in practice?

Ben Shen lies on the forehead, half a cun above the front hairline, well out to the side — roughly above the outer part of the eyebrow rather than above the eye's centre. Our two location records describe it in two complementary ways and are retained unchanged: one places it three cun to the side of DU-24 Shen Ting, which sits on the midline half a cun inside the hairline; the other places it two-thirds of the way along the line from DU-24 out to ST-08 Tou Wei at the corner of the hairline. Both give the same region, and no discrepancy arises between them. Where the hairline has receded, the proportional measurement from DU-24 to ST-08 is the description that still works, which is why the reference literature gives it.

Which points is GB-13 combined with?

• With DU-24 Shen Ting — the closest and most important partner, and the pairing that dominates the modern research literature on this point. DU-24, "Spirit Court", sits on the midline half a cun inside the hairline, directly medial to GB-13, and carries the same spirit-calming reputation; the two names even rhyme in meaning. Bilateral GB-13 with DU-24 makes a three-needle group across the front of the forehead, and it is this exact combination that has been formalised and tested experimentally (see research). DU-24 is held in this library.
• With the extra point Si Shen Chong — the group of four points surrounding DU-20 Bai Hui at the vertex, held in this library, and the other classical scalp grouping used for calming the spirit and benefiting the brain. GB-13 covers the front of the head, Si Shen Chong the crown; they are commonly used in the same treatment and should not be confused with one another.
• With DU-20 Bai Hui and HT-07 Shen Men — the standard combination for insomnia, anxiety and poor memory, joining the head points to the Heart channel's Source and spirit point at the wrist.
• With DU-26 Shui Gou and LIV-03 Tai Chong — for epilepsy and convulsion, adding the point at the philtrum classically used for sudden loss of consciousness and the Liver point used to settle internal wind.
• With GB-20 Feng Chi and ST-40 Feng Long — where phlegm and wind are both implicated: GB-20 at the base of the skull for wind affecting the head, ST-40 as the classical phlegm-resolving point of the leg. Both are held here.
• With GB-14 Yang Bai — its neighbour on the same channel a little lower on the forehead, added for frontal headache and disorders of the eye.
• Along the Gall Bladder head line — GB-13 is the first of a run of points that arcs backward over the side of the skull: GB-14 Yang Bai, GB-15 Tou Lin Qi, GB-16 Mu Chuang, GB-17 Zheng Ying, GB-18 Cheng Ling, GB-19 Nao Kong and GB-20 Feng Chi. All are held here, all are meeting points with the Yang Linking Vessel, and taken together they map the channel's zigzag over the head.

Where does GB-13 sit among its peers?

GB-13's only classification is its meeting-point status with the Yang Linking Vessel, which it shares with sixteen other points held here. What distinguishes it inside that group is its indication set rather than its position: the other Gall Bladder head points are weighted toward the eyes, the ears, headache and dizziness, whereas GB-13 alone carries epilepsy and the mental-emotional territory as its recorded core. Within the broader family of spirit-named points on the head — DU-24 Shen Ting "Spirit Court", GB-18 Cheng Ling "Spirit Support", and Si Shen Chong "Four Spirits Alert", all held here — GB-13 is the one whose name claims the root rather than a court, a support or an attendant.

Where is GB-13 located?

• A Manual of Acupuncture (p. 431): On the forehead, 0.5 cun within the anterior hairline, two thirds of the distance between Shenting DU-24 and Touwei ST-8.
• Chinese Acupuncture and Moxibustion (p. 212): 0.5 cun within the hairline of the forehead, 3 cun lateral to Shenting (DU-24).

How is GB-13 Ben Shen needled?

Reference fact, and the single most important thing recorded about needling this point: GB-13 lies directly over the frontal bone, so the standard texts document transverse — subcutaneous — insertion only. Sacred Lotus sources & references record subcutaneous puncture of 0.3 to 0.5 inch, with moxibustion applicable; Deadman & Al-Khafaji (p. 431) record transverse insertion of roughly 0.5 to 1 cun, directed either posteriorly or in the direction of the complaint. This is recorded as neutral reference data describing what the standard texts state. It is not instruction, and this page does not teach technique. Needling is carried out only by a qualified, licensed practitioner.

Why the angle is transverse — measured anatomy, not a warning

• There is bone immediately beneath. Under the skin at GB-13 lie the epicranial aponeurosis and the frontal belly of occipitofrontalis, and then the outer table of the frontal bone. The soft tissue over the vault of the skull is a few millimetres deep. A perpendicular needle has nowhere to go; a transverse one runs along the plane between skin and bone, which is precisely the plane the texts describe. The angle is dictated by the measured depth of tissue available, not by a hazard.
• What the transverse plane contains is the supratrochlear and supraorbital nerves and vessels running up from the orbital rim, and the superficial temporal vessels further laterally. The scalp is richly vascular, so bleeding and bruising after withdrawal are the ordinarily documented occurrences at scalp points generally — the reference literature treats this as a normal feature of the region rather than as a complication.
• There is no cavity, organ or lung anywhere near this point, and the standard references attach no special prohibition to it. Set against points over the thorax, the upper back or the root of the neck, a point on the vault of the skull needled in the plane of the skin is at the low-hazard end of the range, and it is more useful to say that plainly than to attach a generic caution.
• Moxibustion is recorded as applicable; on the forehead, near the hairline, the practical considerations are the obvious ones of hair and of a cosmetically exposed area.

The general safety picture

For context rather than alarm: a meta-analysis of prospective clinical studies estimated serious adverse events from acupuncture at approximately 1 per 10,000 patients and around 8 per million treatments, with about half of all recorded events being bleeding, pain or flare at the needle site (Bäumler P et al., BMJ Open 2021;11:e045961, PMID 34489268). Bleeding at the needle site is the commonest of all recorded events and the scalp is where it is most often seen, for reasons of blood supply rather than of risk. Our sources record no pregnancy contraindication for GB-13.

What does the name Ben Shen mean?

Ben Shen means "Root of the Spirit" — ben, a root, origin or foundation, and shen, the spirit or consciousness. The name is a direct quotation of a classical principle. Chapter 8 of the Ling Shu (Spiritual Pivot), the second half of the Huang Di Nei Jing, is itself titled Ben Shen — "Rooting in the Spirit" — and opens with the instruction that all needling must first be rooted in the spirit, then sets out how each of the five organs houses one aspect of the mental life: the Heart the shen, the Liver the hun, the Lung the po, the Spleen the yi, the Kidney the zhi. A point named after that chapter is a point named after the foundational statement in Chinese medicine about the mind, and the name is the main reason GB-13 has always been read as a mental-emotional point.

There is a second, quieter reading in the commentaries: ben as root also means base, and the point sits at the base of the hairline over the front of the brain — the root of the head where the spirit is said to reside. Both readings are traditional and the site does not choose between them, though the first is far more widely given and has a text behind it.

Why does GB-13 matter among the spirit points of the head?

The head carries a cluster of points whose names are about the mind, and reading them together is more useful than reading any of them alone. DU-24 Shen Ting, "Spirit Court", sits on the midline three cun medial to GB-13 and is its constant partner. GB-18 Cheng Ling, "Spirit Support", lies further back on the same channel. The extra point group Si Shen Chong — four needles around the vertex — surrounds DU-20 Bai Hui at the crown. All are held in this library. Against these, GB-13's claim is the strongest one available in the vocabulary: not a court where the spirit is received, nor a support, nor an attendant, but the root. Whether that reflects an ancient judgement about the point's power or simply the accident of borrowing a chapter title is not something the sources settle, and this page does not pretend otherwise.

Is there research on GB-13 Ben Shen?

GB-13 has a small but genuinely point-specific research literature, and it is unusual in one respect: almost all of it studies GB-13 in a fixed three-needle combination with DU-24 Shen Ting, and at least one study tested the combination against its component points to see whether the pairing does anything the points do not do separately. The work is overwhelmingly preclinical — rodent models of Alzheimer's disease — with one small clinical trial. That should be stated up front, because preclinical mechanism work is not evidence of clinical benefit.

• The GB-13 + DU-24 combination, formalised and tested. A study in 5xFAD transgenic mice — a standard model overexpressing amyloid-β — examined a combined electroacupuncture protocol the authors call TNEA, whose constituent points are bilateral GB-13 and DU-24, and compared it against electroacupuncture at each component point alone. The combination inhibited activation of the NLRP3 inflammasome and promoted its autophagic degradation, and the authors reported synergistic effects of the combined points over the single points on the pathways measured, alongside improvement in memory-related behaviour (Lin W et al., J Neuroinflammation 2023;20(1):21, PMID 36732771). The design is what makes it worth citing: the combination itself, not just acupuncture in general, was the variable.
• Cognitive and molecular outcomes in a rat model. Sixty Sprague-Dawley rats were divided into control, model, electroacupuncture and non-acupoint groups, with electroacupuncture applied at DU-24 and bilateral GB-13. The electroacupuncture group performed better on cognition-related behavioural tests and showed lower hippocampal levels of amyloid-β and of tau phosphorylated at serine-396 and serine-404 than the model group (Yang Y et al., Neuroreport 2020;31(15):1072–83, PMID 32881772, PMC7515480). The inclusion of a non-acupoint arm makes this a point-specificity design as well as an efficacy one.
• Brain imaging in the same model. A companion study examined cerebral responses to acupuncture at DU-24 and bilateral GB-13 in rat models of Alzheimer's disease, again with a non-acupoint comparison group, reporting distinguishable patterns of cerebral response alongside improvement in learning and memory (Cui S et al., Behav Neurol 2018;2018:8740284, PMID 29854022).
• The one clinical trial. Seventy children with autism spectrum disorder were randomised to routine rehabilitation training alone or to the same training plus electroacupuncture at GB-02 Ting Hui and GB-13 Ben Shen, disperse-dense wave, twenty minutes a session over twelve weeks. The electroacupuncture group showed a lower total incidence of abnormal auditory response and a lower incidence of auditory hypersensitivity than the control group, with greater reductions in Childhood Autism Rating Scale and Autism Behavior Checklist scores (Que XQ et al., Zhongguo Zhen Jiu 2023;43(1):36–9, PMID 36633237). Single-centre, unblinded, seventy children, and an add-on rather than a stand-alone design — so it is a promising small trial rather than a basis for any claim. GB-02 Ting Hui is held in this library.

The honest summary: no adequately powered clinical trial isolates GB-13 for epilepsy, insomnia or any of its principal traditional indications. What it has is a coherent classical rationale rooted in a named chapter of the Ling Shu, a consistent documented use across the reference literature, and a small preclinical literature that has at least been designed to ask the right question — whether this point, and this pairing, do something a nearby non-point does not.

How does Ben Shen compare with the points around it?

DU-24 Shen Ting is three cun medial on the midline, at the same depth inside the hairline, and is the point GB-13 is most often used with and most often confused with; the difference is simply midline against lateral, Governing Vessel against Gall Bladder channel. ST-08 Tou Wei marks the corner of the hairline further out, and is the landmark from which GB-13 is proportionally measured. GB-14 Yang Bai sits lower, one cun above the middle of the eyebrow, and is the local point for the eyebrow region and frontal headache rather than for the spirit. DU-23 Shang Xing lies on the midline one cun inside the hairline, above DU-24, and is weighted toward the nose and eyes. The extra point group Si Shen Chong occupies the crown, not the forehead. Among all of these, GB-13 is the one whose recorded indications lead with epilepsy and with the mind — and its position, forward and lateral over the frontal bone, is what makes the transverse needling angle recorded in the texts a matter of anatomy rather than of caution.
