What is ST12?

ST12 (Quepen) is a Stomach channel point in the soft hollow just above the middle of the collarbone. Its Chinese name means "empty basin", which is a plain description of the dip you are feeling for.

In classical theory ST12 is a crossing point where several yang channels pass through the neck and shoulder region. Traditional texts link it to the throat, the chest and the downward movement of Stomach energy, so it is listed for hiccups, cough, throat tightness and shoulder-neck pain. Every curriculum teaches it, but few practitioners use it as a main point.

Two things matter before you press anything here. Traditional standing is not evidence that a point works, and long use in tradition is not evidence that it is safe. Those are separate questions, and this page answers them separately.

The honest verdict on evidence: there is essentially no human research testing finger pressure on ST12 for anything. Where ST12 appears in studies, it is one of several needled points in a mixed formula, so no result can be pinned on it. That is weaker evidence than you will see claimed in videos.

ST12 also deserves more physical care than most points. The hollow above the collarbone contains lymph nodes, large blood vessels and the nerve bundle that runs to the arm, and the top of the lung sits underneath. Finger pressure does not reach the lung, but hard digging in this hollow can bruise, pinch a nerve or make you feel faint. Acupuncturists treat this as a cautious area for needling because of the risk of a collapsed lung; that history is a reasonable reason for you to stay gentle, not a reason to panic about touching it.

Everything described on this page is self-applied finger pressure. Nothing here involves needles, heat, suction or anything that breaks the skin.

Where is ST12 and how do you find it?

ST12 sits in the dip just above the collarbone, about midway between the base of your throat and the point of your shoulder.

• Find the two ends of the collarbone. Put a fingertip in the U-shaped notch at the base of your throat. Then find the bony tip of your shoulder. Your collarbone runs between them.
• Walk out along the top edge. Slide your finger pad slowly along the upper edge of the bone, moving away from the throat. Stay on the bone so you do not lose your place.
• Stop at the midpoint. Roughly halfway along the bone, the hard edge gives way to a soft dip above it. This supraclavicular fossa (the hollow above the collarbone) is where ST12 is located.
• Check the line down your body. Classical texts put ST12 four cun from the front midline, which in most adults is about 8 to 10 cm out from the centre of the breastbone. It falls roughly in line with the nipple below it.
• Confirm by feel. The spot is soft and slightly tender under light pressure. You should be able to rest a fingertip in the hollow without touching bone.

Two landmarks tell you that you have gone too far in. If you feel a strong pulse under your finger, you have drifted too close to the midline and the big neck vessels; move outward. If you feel a zing or tingle down your arm, you are on the nerve bundle; lift off and shift slightly.

Sides are equivalent. Sit upright with your shoulder relaxed and your head level, because hunching flattens the hollow and makes the landmark hard to feel. If you cannot find a clear dip, do not substitute a nearby point or press harder to "find" it.

How do you apply pressure to ST12?

1. Sit down first. Pressure near the neck can make some people feel light-headed. Sit in a chair with your back supported so a dizzy spell cannot turn into a fall.
2. Use a flat finger pad. Place the pad of your index or middle finger in the hollow. Never use a fingernail, a knuckle, a pen cap or a massage tool here.
3. Press straight down, lightly. Aim for gentle pressure that feels like a dull ache, no more than about three out of ten on a discomfort scale. This is one of the lightest-touch points on the body.
4. Hold or circle slowly. Either hold steady for 20 to 30 seconds, or make small slow circles. Breathe out as you press and let your shoulder drop.
5. Work one side at a time. Do the left, release fully, then do the right. Do not press both hollows firmly at the same moment.
6. Keep sessions short. Two to three rounds per side, once or twice a day, is plenty. There is no benefit to grinding away at this spot.
7. Release slowly. Lift your finger gradually rather than snapping it away, then sit still for a few breaths before standing.

Stop immediately and do not repeat if you feel any of these: dizziness or faintness, a pounding or racing pulse, tingling or weakness running into the arm or hand, shortness of breath, or sharp rather than dull pain.

Stop for the day if the area is still tender an hour later, and give it a full rest if you see bruising. Tenderness that builds over several sessions is a signal to stop, not to push through.

If you have given ST12 a fair trial of a week or two with no change in what you were hoping to help, stop using it for that purpose. Pressure that is not helping is not worth repeating.

What is ST12 traditionally used for?

• Hiccups and belching. Tradition treats ST12 as a point that helps Stomach energy move downward, so it appears in old formulas for hiccups and rising belching. Human evidence for finger pressure on ST12 for hiccups is absent; the few hiccup studies that include it use needles and several points together.
• Cough and chest tightness. Classical texts list ST12 for cough, wheezing and a feeling of fullness in the chest. No controlled trial has tested pressing this point for cough, and nothing here should replace treatment for asthma or a chest infection.
• Sore or tight throat. The point sits on a channel described as passing through the throat, so texts mention throat pain and a sensation of something stuck. Evidence is limited to tradition; there is no trial showing finger pressure changes throat symptoms.
• Neck and shoulder tension. Modern practitioners sometimes use the area for stiffness across the top of the shoulder. Gentle pressure on tight muscle can feel good in the moment, which is a plausible comfort effect rather than a proven treatment.
• Pain or numbness in the arm. Some texts link ST12 to problems radiating down the arm, because the nerves to the arm pass beneath. This is also exactly why tingling during pressure means stop, not continue.

Read all of these as claims from tradition, not findings. The honest summary is that ST12 has no specific human evidence behind any of its listed uses. That is different from saying it does nothing; it means nobody has properly looked.

For comparison, one acupressure claim does have real support: PC6 on the inner forearm has been tested in many controlled trials for nausea and vomiting, with a modest but genuine effect. ST12 has nothing of that kind. If a video presents ST12 as being on the same footing, it is overstating the case.

Are there tips for using ST12 effectively?

• Let your shoulder drop first. The hollow all but disappears when your shoulders are raised. Exhale, let the shoulder sink, then feel for the dip.
• Less pressure, not more. This is a soft, crowded hollow. If a point ever deserves a feather touch, it is this one, and heavier pressure here does not mean a stronger effect.
• Use the opposite hand. Reaching across your body with the other hand gives you a better angle and makes it harder to bear down with your weight.
• Warm the area first. A warm shower or a warm flannel on the shoulder for a minute makes the surrounding muscle easier to work with and the pressure more comfortable.
• Pair it with breathing, not with force. Slow nasal breathing while you hold gives you something measurable to do and makes relaxed posture more likely.
• Keep a simple log. Note the date, how long you pressed and your symptom score out of ten. Two weeks of notes will tell you far more than a general impression.
• Set an end date for the trial. Decide in advance that you will review after ten to fourteen days. If nothing has shifted, stop rather than drifting on indefinitely.
• Treat it as an add-on. Use ST12 alongside your prescribed treatment, your inhaler or your reflux medicine, never instead of them.
• Check your nails. Short, smooth nails prevent scratches in thin skin over the collarbone, especially if you bruise easily.

One more practical point: expect a quiet, local sensation at most. A dull ache under the finger and a slight easing of shoulder tightness is the normal ceiling. Dramatic sensations are a reason to stop and reassess, not a sign that it is working.

What do people get wrong with ST12?

• Digging in hard. Treating the hollow above the collarbone like a tight calf muscle. Deep gouging here bruises easily and can pinch the nerves that run to the arm.
• Drifting towards the throat. Sliding too far inward and pressing near the big neck vessels. If you feel a strong pulse under your finger, you are in the wrong place; move outward along the collarbone.
• Pressing both sides at once. Squeezing both hollows firmly together, which is more likely to make you feel faint. Work one side, release, then the other.
• Pressing on a lump. Mistaking a swollen gland for the point. A new, hard or fixed lump above the collarbone needs a doctor's assessment, not pressure.
• Using a tool. Reaching for a pressure pen, knuckle or massage gun. The structures here are shallow and a hard edge concentrates force where you do not want it.
• Expecting a cure. Hoping ST12 will clear a chronic cough, reflux or asthma. No acupressure point cures these conditions, and treating it that way can delay care you actually need.
• Pushing through tingling. Carrying on when a zing runs into the arm, assuming it means the point has been "activated". It means you are on a nerve; lift off.
• Ignoring breathlessness. Using the point for chest tightness that is actually worsening. New or severe breathing difficulty is an emergency, not a self-care situation.
• Pressing near hardware. Working directly over a pacemaker, port or central line, which often sit just below the collarbone. Keep well away from any implanted device.
• Judging too fast. Deciding after one go that it does or does not work. Short-term relief that fades in minutes is common with any touch and is not proof of a lasting effect.

What does the research on ST12 actually say?

No useful human research on ST12 by itself was found. There is no controlled trial of finger pressure on Quepen for hiccups, cough, throat symptoms, shoulder pain or anything else. That is the plain answer, and it is the answer for most individual acupoints.

Where ST12 does appear in the literature, it is almost always one name in a list. Acupuncture studies for persistent hiccups and for neck and shoulder pain sometimes include it alongside several other points, and those studies use needles rather than fingers. When a multi-point needling protocol shows a result, there is no way to tell which point, if any, contributed. Acupressure results cannot be read across from needling results either, since the intervention is different.

The wider acupressure evidence base has well-known limits. Most trials are small, short and unblinded, meaning participants know they are being treated, which inflates reported improvement in subjective symptoms like pain and tightness. Follow-up is usually days or weeks, not months.

There is one clear exception worth knowing, because it shows what decent evidence looks like. PC6 on the inner forearm has been tested in many randomised trials for nausea and vomiting, including after surgery and in pregnancy, and reviews find a modest but real benefit. Nothing like that body of work exists for ST12.

What this means for you is modest. Gentle pressure at ST12 is a low-cost thing to try for shoulder tension or comfort, and it may feel pleasant, but you should not expect a specific or lasting effect, and you should not substitute it for care of a cough, reflux, a lump or arm symptoms. If someone cites a study proving ST12 treats a named condition, ask to see it and check whether the study tested that point on its own.
