A powerful point on the crown of the skull, Qiangjian (GV-18) works where the Governing Vessel meets the head. It clears the mind, calms mental agitation, and relieves stubborn headaches — especially those with a strong, forceful quality.
Name & story
The name 强间 Qiangjian carries the sense of 'strong space' or 'unyielding interval' — 强 (qiáng) means strong or forceful, and 间 (jiān) means space or gap. The point sits on the Governing Vessel at the back of the skull, in the space between strong bones. It is as though the name itself describes what it treats: the kind of headache that feels hard, pressing, unyielding — and the kind of mental restlessness that refuses to let go. Qiangjian meets that force with its own.
Point family & character
Qiangjian (GV-18) belongs to the Governing Vessel (GV), the great Yang channel that runs up the spine and over the crown of the head. It sits on the posterior scalp, between Naohu (GV-17) below and Houding (GV-19) above, making it part of the remarkable sequence of points the Governing Vessel places along the occiput and crown.
Five-element dynamics
The Governing Vessel is the 'Sea of Yang channels', gathering and directing Yang Qi through the back and up into the brain. Points high on the skull, like GV-18, sit close to the uppermost Yang of the body — the head, where Yang naturally rises. When Yang Qi or Wind rushes upward in excess — driven by Liver Yang, Heat, or internal Wind — it can surge into the head causing headache, stiffness, and mental turmoil. GV-18 works at this uppermost level to settle what has risen too forcefully and calm the agitated Shen.
Location
GV-18 is located on the midline of the head, on the posterior scalp. It sits 1.5 Cun above Naohu (GV-17) and 1.5 Cun below Houding (GV-19), along the midline between the occiput and the crown.
Anatomy & fascia
The point lies on the posterior scalp, in the occipital region, where the galea aponeurotica (the tough fibrous sheet of the scalp) and the occipitalis muscle are found.
Needling
The needle is inserted horizontally (transversely) along the scalp, directed either forward or backward along the channel.
Safe depth
0.3–0.5 Cun horizontally under the scalp.
Moxa, cupping & Tui Na
Gentle massage along the Governing Vessel over the posterior scalp can complement needling. Mild moxa may be used with caution on scalp points, though direct needling is the more common approach here.
Functions
Clears the mind and calms the Shen; Subdues internal Wind; Relieves headache; Benefits the head and occiput; Calms mental agitation and restlessness.
Indications
Headache, particularly occipital or vertex headache with a strong, forceful quality. Stiffness and pain in the neck and occiput. Dizziness and vertigo. Mental restlessness, agitation, and difficulty calming the mind. Epilepsy and convulsions related to internal Wind. Vomiting.
Mind & spirit (Shen)
GV-18 has a quieting effect on the mind. When Yang rises too hard and fast — whether from Liver Yang, internal Wind, or unrelenting mental tension — the Shen is swept along with it: the person cannot rest, cannot let a thought go, feels a kind of forceful inner pressure. By working at the top of the Governing Vessel, where all that Yang energy converges, this point helps settle the storm. It is not a gentle sedative point so much as a point that meets intensity with steadiness, useful when the mind is agitated rather than merely anxious.
Point combinations
With GV-20 (Baihui) — for vertex headache and calming the mind, working along the Governing Vessel on the crown. With GV-16 (Fengfu) — for occipital headache, stiff neck, and internal Wind. With GV-23 (Shangxing) — for headache along the Governing Vessel from front to back.
Clinical spotlight
GV-18 is one of several Governing Vessel points that address the head from the posterior scalp upward to the crown. Its particular value lies in headaches and mental states with a forceful, unyielding quality — where something seems to be pushing or pressing in the head. Located in the sequence between GV-17 and GV-19, it forms part of the chain of points the Governing Vessel places over the skull, each with a slightly different emphasis on calming, lifting or clearing the head.
The golden tip
For tension and tightness at the back of the head, gentle self-massage along the midline of the posterior scalp — from the base of the skull upward — can ease discomfort. Working slowly along this line with the fingertips, pausing where you feel tenderness, supports the calming action of these Governing Vessel points.
