What Shenmen does
Shenmen is treated here as a practical point rather than a curiosity: where it sits, how it is needled, what the tradition says it does, and the skin conditions in this database that name it.
Actions
- Calms the Mind and opens the Mind's orifices
- Nourishes Heart Blood
Location
The written location is summarised from the classical record; use the landmark named there together with the diagram.
How to find it
Find the bony landmark first, then feel for the hollow or tender spot the location describes. The point is usually sensitive when pressed. Ask the patient to rest the forearm supinated on a table. The wrist crease shifts with hand position, so use the proximal edge of the pisiform bone as the fixed marker instead. Shenmen lies in the hollow on the radial side of the flexor carpi ulnaris tendon, level with that bony edge. It shares a line with Yinxi HE-6, Tongli HE-5 and Lingdao HE-4, which sit on the radial side of the same tendon at half-cun steps.
Deqi
De qi at this point is felt as local distension, heaviness or aching, and may travel a short way along the channel.
A cun is a proportional body measurement, not a fixed length: one cun is about the width of the thumb at the knuckle, 1.5 cun about two finger widths, and 3 cun about the width of four fingers. On an average adult one cun is roughly one inch, but it scales with the person, which is why the texts measure in cun rather than centimetres.
Technique
Needling
Angle: 90 degrees, perpendicular Depth: Standard depth half a to half a cun. Direction: Needle in the direction the location describes.
Moxibustion
Five to fifteen minutes with a moxa stick or indirect moxa is the recorded range. Direct scarring moxa is not recommended at the wrist because the skin is thin over the artery and nerve, so the practitioner keeps to gentle warming, often for a pale tongue and a restless, deficient picture.
Cupping
The reference marks cupping at this point as questionable. The wrist is small, superficial and crossed by the ulnar artery and nerve, so the area is usually left alone rather than subjected to suction.
Skin uses
Shenmen is the Yuan-source point of the Heart channel, recorded to calm the Mind, open the Minds orifices and nourish Heart Blood. Its skin relevance is indirect and emotion-centred: where a skin picture is described as worse with anxiety or sleeplessness, the recorded action of settling the spirit and nourishing Heart Blood is the traditional reasoning that supports considering it alongside the pattern. The classical record lists spirit disorders and constitutional weakness, not the skin. With no skin-specific classical indication recorded for it, the rationale relies on traditional inference, not trial evidence.
No skin-specific classical indication is recorded for this point. The rationale above is an indirect, traditional reading of the point, not a promise of benefit.

Classical record
The classical record summarises the classical use of this point without quoting a passage in full.
classical record
For incontinence, Guanmen and Shenmen are the main points, needled together with Weizhong.
Zhen Jiu Jia Yi Jing (Systematic Classic of Acupuncture and Moxibustion), classical citation recorded from the reference
The Nan Jing calls this point Duigu and names it the Yuan-Source point of the Heart channel, the place where the channel's original Qi surfaces at the wrist.
Nan Jing (Classic of Difficulties), chapter 66, classical citation recorded from the reference
It lists spirit disorders first among the point's uses, then adds malaria, insufficient Qi, wheezing, counterflow Qi, vomiting of blood, excessive body heat, incontinence, and epilepsy in children and adults.
Tong Ren Shu Xue Zhen Jiu Tu Jing (Illustrated Manual of Acupuncture Points on the Bronze Figure), classical citation recorded from the reference
For Cold Damage with obstruction of the throat, needle the Hand Shaoyin point at the wrist beside the little finger, over the moving artery, inserting three fen and tonifying.

Safety
Who should treat this point
Acupuncture and moxibustion are practitioner procedures. This page is educational and is not a guide to self-treatment.
Caution
No special hazard is recorded for this point; use standard care for the region and adjust depth to the patient. The ulnar artery and ulnar nerve run beside this point, and a deep needle can meet them, so insertion stays shallow and is directed slightly towards the ulnar side. The reference rules out scarring moxibustion here; indirect moxa or a moxa stick is the appropriate form. Transverse needling parallel to the wrist crease, deep to the tendon, is an alternative where the point is hard to reach.
Deficiency and constitution
In a depleted patient the point is worked gently and briefly. Where Heart Blood or Yin is depleted the point is needled gently and briefly, since the aim is to nourish rather than to move. In anxious, sleepless patients a light calming technique suits better than strong stimulation, which can leave them more restless.
Before treatment
Educational reference only. Skin that is spreading, painful, blistering or accompanied by fever needs medical assessment.

Evidence note
No controlled trial of this treatment in skin conditions was identified for this entry. What is described here rests on the classical and later materia medica record and on traditional clinical use, not on controlled trial evidence, and it is not a prediction of benefit. Where skin-specific research does exist it is linked above.
Common questions
What does Shenmen do in skin practice?
It is used where the skin picture includes the conditions it is used with, always as part of a combination chosen for the pattern.
How is it needled?
90° (Perpendicular) / 45° (Oblique). Standard depth 0.3 - 0.5 cun. De qi: Local distention and soreness at the wrist. A characteristic deqi may include a numb, tingling, or mild electric sensation extending toward the fingertips along the ulnar side of the hand. Some patients experience a calming or settling sensation as the spirit is calmed.
When is Shenmen the wrong choice?
Where the pattern is excess rather than deficient. With Heart Fire or Phlegm Fire the reference prefers Jianshi P-5 or Shaofu HE-8, and Shenmen is kept for the deficient picture of anxiety, worry and sleeplessness with a pale tongue rather than a red one and a rapid pulse.
