What is GB5?

GB5 (Xuanlu) is a Gall Bladder channel point on the side of the head, in the hairline above and in front of the ear.

Its Chinese name is usually translated as "suspended skull", a reference to its position on the curve of the temple. Classical texts group it with GB4, GB6 and GB7 as the head points of the Gall Bladder channel, and they were used mainly for one-sided head pain, eye pain and facial swelling.

In modern teaching GB5 is a standard but minor point. Every curriculum lists it, few practitioners build a treatment around it, and it is almost always used alongside other points rather than alone.

Here is the honest verdict on the evidence: no published human study has tested GB5 by itself, and none has tested finger pressure on GB5 for anything. There is reasonable trial evidence that acupuncture as a whole treatment can reduce migraine frequency, but those trials used needles, used many points, and cannot be read as proof that pressing this one spot works.

Two things are worth saying once, clearly, because they apply to everything below. First, the fact that a point has been used for a thousand years tells you it was valued; it does not tell you it works. Second, long traditional use is not a safety record either. The temple is a thin, sensitive area with a surface artery running through it, so the cautions on this page are real and specific, not boilerplate.

What GB5 realistically offers a layperson is a comfortable, low-risk way to self-massage a tense temple. Many people find that soothing. That is a reasonable thing to want, and it is a smaller claim than the one you may have heard in a video.

Where is GB5 and how do you find it?

GB5 sits in the temple hairline, midway along the curve between the front corner of your hairline and the point just in front of the top of your ear.

• Find the front anchor. Put a fingertip at the corner of your forehead where the hairline turns to go down the side of your head. That upper anchor is the point ST8 (Touwei).
• Find the lower anchor. Slide a finger forward from the top of your ear until you feel the edge of the hairline in front of it. That lower anchor is GB7 (Qubin), roughly level with the top of the ear.
• Trace the curve. Draw an imaginary curved line through the hairline joining those two anchors. It follows the hairline rather than cutting straight across.
• Take the midpoint. GB5 is at the halfway mark on that curve. On most adults that is about 3 to 4 cm (roughly two thumb-widths) down from the front corner of the hairline.
• Confirm by feel. You should be on soft muscle, not on the bony forehead edge. Clench your teeth; the slab of muscle that bulges under your finger is the temporalis, and GB5 lies over its upper part.

A useful check: GB5 is inside the hairline. The well-known hollow at the temple, Taiyang, sits in front of and below the hairline, beside the eyebrow end. If your finger is in a dip next to your eye, you have the wrong spot.

You may feel a soft pulse somewhere in this region. That is the superficial temporal artery, which runs up through the temple. Note where it is and stay beside it rather than on it.

Both sides of the head carry a GB5. Traditional practice usually works the side that hurts, or both sides together.

This is a finger-pressure reference only. Nothing here describes needling, and you should not attempt to needle any point on yourself.

How do you apply pressure to GB5?

1. Clean hands, trimmed nails. You are working on scalp skin near the eye, so wash your hands and keep nails short. Use the soft pad of a finger, never a nail tip or a hard tool.
2. Sit supported. Sit in a chair with your elbows resting on a table or on the arms of the chair. This stops your shoulders tensing while you work.
3. Place the finger. Put the pad of your middle or index finger on GB5 in the temple hairline. If you feel a pulse under the pad, shift about a centimetre forward or back so you are beside the vessel, not on it.
4. Press lightly. Build pressure slowly to about 3 out of 10 — firm enough to feel a dull spread, never sharp. The temple takes far less pressure than a shoulder or a hand.
5. Hold or circle. Either hold still for 30 to 60 seconds, or make small, slow circles that move the scalp over the bone rather than dragging across the skin. One to two minutes per side is plenty.
6. Keep breathing, unclench the jaw. Let your teeth part slightly and breathe out slowly. A clenched jaw hardens the muscle under your finger and makes the whole thing less comfortable.
7. Repeat sensibly. Two or three short sessions a day is a reasonable ceiling. More is not better here, and long heavy rubbing can leave the temple tender for hours.

Stop straight away if the pressure sharpens your headache, makes you dizzy or nauseated, blurs your vision, or produces any tenderness that lingers after you let go.

Stop and leave the area alone if the skin becomes red, sore or bruised, and do not resume until it is completely normal again.

Finger pressure only. Do not use needles, heat, burning herbs, suction cups or anything that breaks or marks the skin on this or any point.

What is GB5 traditionally used for?

• One-sided and temple headache. This is the main classical use of GB5, and the reason most videos mention it. The honest position: no trial has tested GB5 alone, though multi-point acupuncture for migraine prevention does have moderate-quality controlled evidence behind it.
• Migraine support. Tradition treats the temporal Gall Bladder points as a group for migraine-type pain. Acupressure migraine studies are small, short and unblinded, and they rarely isolate GB5, so treat this as plausible comfort rather than proven treatment.
• Tension and jaw clenching. GB5 sits over the temporalis, a muscle that aches in people who clench or grind. Gentle self-massage over a tight muscle is a sensible, well-understood thing to do, even though no study has tested this specific point for it.
• Eye discomfort and tired eyes. Classical sources list red, painful eyes among GB5's indications. There is no modern human evidence for that use; people who sit at screens often simply find temple massage pleasant.
• Toothache and facial swelling. Old texts name these. Modern dentistry treats the cause instead, and no research supports pressing GB5 for dental pain. A tooth that hurts needs a dentist, not a temple point.
• Tinnitus and ear fullness. Listed in some traditional sources because the channel passes the ear. Human evidence for acupuncture or acupressure in tinnitus is weak and inconsistent, and nothing specific to GB5 exists.

A fair summary: GB5's traditional reputation is all about pain on the side of the head. The research that exists is about acupuncture as a whole package, not about this point, and certainly not about your fingers on this point.

If you try it, judge it the way you would judge any self-massage. Does it make the next hour easier? That is a reasonable standard. Expecting it to end a migraine disorder is not.

Are there tips for using GB5 effectively?

• Work both sides. Even if only one temple aches, giving both sides the same short treatment feels more balanced and stops you leaning into one side of your head.
• Move the scalp, not over it. Small circles that shift the skin and muscle across the bone are far more comfortable than rubbing your fingertip across dry scalp, which just irritates the skin.
• Unclench first. Before you start, let your jaw drop open for a few seconds. The temporalis softens immediately, and GB5 stops feeling like a bruise.
• Dim the room. If you are using it for headache, pair it with low light and a few minutes of quiet. Much of the benefit people report from temple massage comes from stopping and resting.
• Stay light. The temple needs much less force than a hand or foot point. If your finger is leaving a dent or your eye waters, you are pressing too hard.
• Keep sessions short. One to two minutes a side is enough. Long sessions tend to leave the area sore without adding anything.
• Avoid oily fingers near the eye. If you use balm, keep it well away from the eyelid and wash your hands afterwards. Menthol balms sting badly if they migrate.
• Track it honestly. Note in a diary when you used it and what your headache did over the next few hours. Headaches vary a lot on their own, so a few impressions are easy to misread.
• Treat it as one part of a routine. Sleep, hydration, caffeine timing and screen breaks move headaches more reliably than any single pressure point. Use GB5 alongside those, not in place of them.
• Ask about your medication. If you take regular headache or migraine medicine, keep taking it as prescribed and raise any change with your prescriber first.

What do people get wrong with GB5?

• Expecting a cure. This is the biggest one. GB5 is a self-massage spot with no trial evidence of its own, and anyone promising it will cure migraines is overselling it.
• Pressing Taiyang instead. The famous hollow beside the eyebrow is a different point, outside the hairline. GB5 is inside the hairline, about halfway down the curve from the forehead corner to the front of the ear.
• Landing on bone. If your finger is on the hard ridge at the edge of your forehead, slide back into the soft muscle. Grinding a fingertip on bone is just painful.
• Pressing on the pulse. Some people feel a pulse at the temple and aim straight for it. Move a centimetre off and work beside the artery, not on it.
• Using far too much force. Temple skin is thin and bruises easily. Hard digging can leave you tender for a day and sometimes makes a headache worse, not better.
• Using fingernails. A nail edge on scalp skin can scratch and break the surface. Pads only.
• Ignoring a new kind of headache. Pressing a point while a headache pattern changes, worsens or wakes you at night delays a diagnosis that may matter. Get it looked at.
• Working over a rash or wound. People press straight through shingles blisters, cuts or sunburn on the temple. Leave damaged skin completely alone until it has healed.
• Treating a toothache with it. The classics list toothache, but a painful tooth has a physical cause that pressure cannot fix. See a dentist.
• Stopping prescribed medicine. Nobody should swap a preventive migraine drug for a pressure point. Changes to medication belong with the person who prescribed it.

What does the research on GB5 actually say?

There is essentially nothing on GB5 specifically. We found no human trial, no controlled study and no decent case series testing GB5 alone, by needle or by finger pressure, for headache or for anything else.

What does exist sits one level up. Cochrane reviews of acupuncture for migraine prevention and for tension-type headache have pooled a number of randomised trials and concluded that acupuncture can reduce headache frequency, with effects at least as good as prophylactic drug treatment in some comparisons. Those are needle trials using multi-point prescriptions, often including temporal points on the Gall Bladder channel. They do not isolate GB5, and they cannot tell you what your own fingertip will do.

Acupressure research on headache is thinner again. The trials are typically small, unblinded, short in follow-up, and compared against resting or against a sham point, which is a weak control because both groups get touch and attention. Several report modest short-term reductions in pain scores. None of them is a GB5 study.

What this means in practice is simple. If someone tells you research proves GB5 relieves migraine, they are stretching migraine acupuncture evidence over a point that was never tested on its own. The honest grade for GB5 is insufficient.

That is not the same as saying it is useless. Gentle massage of a tight temporalis muscle is a reasonable comfort measure with a very low risk of harm, and plenty of people find a few quiet minutes with their fingers on their temples genuinely settling. Just keep the claim the right size.

If better research appears — a trial that isolates this point and uses a credible control — this page will be updated to say so.
