What is ST10?

ST10 (Shuitu) is a Stomach-channel point on the front side of the neck, on the forward edge of the strap muscle, below the Adam's apple.

Its Chinese name is usually translated as "Water Prominence". Classical texts group it with its neighbours ST9 and ST11 as a throat-and-neck point, used for sore throat, hoarseness, cough, wheezing and swellings of the neck. It appears in standard point lists and teaching curricula, but it is a point most practitioners use sparingly, because of what lies underneath it.

That anatomy matters more than the tradition here. The carotid artery, the carotid sinus (a pressure sensor that helps control blood pressure), the jugular vein, the vagus nerve and the thyroid gland all sit in this small area. Firm pressure here can slow the heart or cause fainting in some people, which is why ST10 is one of the few points we describe mainly so you can locate it and leave it alone.

Traditional standing is not evidence that a point works, and it is not evidence that a point is safe. A point can be in every classical text and still have no human trials behind it, and still sit over a structure you should not squeeze. Both of those are true of ST10.

The honest verdict on the evidence: there are no controlled human trials of acupressure at ST10 for any condition that we could identify. Anything you read claiming it shrinks a goitre, clears asthma or lowers blood pressure is going well beyond what has been tested. The general acupressure literature is mostly small, unblinded and short-term, and ST10 has not even had that much attention.

If you came here from a video that told you to press your throat, the useful takeaway is this: light contact at most, one side only, never the pulsing vessel, and see a doctor about neck lumps, swallowing trouble or breathing trouble rather than pressing on them.

Where is ST10 and how do you find it?

ST10 sits on the front edge of the sternocleidomastoid, the rope-like neck muscle, roughly a thumb-width below the level of the Adam's apple.

• Find the Adam's apple. Sit upright and run a fingertip down the midline of your throat. The firm ridge you meet is the thyroid cartilage, the Adam's apple. It is easier to feel in men, but it is there in everyone.
• Find the strap muscle. Turn your head firmly to the opposite side. A thick cord stands out from behind your ear down to your collarbone. That is the sternocleidomastoid. Relax your head again and keep a light finger on its front edge.
• Drop below the cartilage. From the level of the Adam's apple, move about one thumb-width (roughly 2 cm) down the front edge of that muscle. ST10 is described at the midpoint between ST9, level with the Adam's apple, and ST11, just above the inner end of the collarbone.
• Check what you are touching. If you feel a strong pulse under your fingertip, you are on the carotid artery. That is not the spot to press. Shift slightly outward onto the muscle edge itself, or simply stop.

Classical sources place ST10 one cun below ST9, which works out at about one thumb-width on most adults. Both the classical and modern descriptions agree on the general neighbourhood: front border of the sternocleidomastoid, between the Adam's apple and the collarbone. Sources differ slightly on the exact height, so treat it as a small zone rather than a dot.

Everything on this page is self-applied finger pressure. We do not give needle instructions for any point, and the throat is a particularly poor place to experiment.

How do you apply pressure to ST10?

1. Decide whether to touch it at all. ST10 lies over the carotid artery, the carotid sinus and the thyroid gland. If you have any heart, artery, thyroid or fainting history, read the "Who should avoid it" list first and pick a different point.
2. Sit down. Never work on the front of the neck while standing, driving or in the bath. If you do feel light-headed, sitting means you simply lean back rather than fall.
3. Locate, then check for a pulse. Rest one fingertip on the front edge of the neck muscle. If you feel a beat, move off it. Pressure on a pulsing neck vessel can slow the heart rate sharply.
4. Use feather-light contact only. A resting fingertip, enough to warm the skin and no more. This is not a point for deep pressure, digging, kneading, knuckles or massage tools.
5. Keep it brief. Up to about 30 seconds of light contact, with slow easy breathing, once or twice in a session. Longer and harder is not better here.
6. One side at a time. Never press both sides of the front neck together, and never with both hands at once.
7. Stop at the first odd feeling. Dizziness, a thumping or slowing heartbeat, ringing ears, visual greying, nausea, a lump-in-throat feeling or breathlessness all mean take your hand away and sit still until it passes.

How often? Occasional light use at most, and only while you feel completely normal. There is no evidence that frequent or prolonged pressure here helps anything, so there is no payoff to balance the risk.

If your goal is throat comfort or a calmer cough, safer and better-studied options exist away from the neck, such as LU7 at the wrist or LI4 in the web of the hand. Nothing here replaces medical care for a throat or breathing problem.

What is ST10 traditionally used for?

• Sore throat and hoarseness. Classical texts list ST10 for throat pain, a blocked-feeling throat and loss of voice. No controlled human trial has tested acupressure at ST10 for any throat symptom, so this rests on tradition alone.
• Cough and wheezing. Tradition describes ST10 as calming "rebellious qi" rising up the throat, and so lists it for coughing and asthmatic breathing. There is no human evidence for this point, and wheezing needs a proper diagnosis and prescribed treatment, not finger pressure.
• Swellings of the neck. Old sources use ST10 for goitre (an enlarged thyroid gland) and scrofula, a term covering chronic neck lumps. Nothing in the research literature suggests pressure changes a thyroid or a lymph node. Any new or growing neck lump is a see-a-doctor matter.
• Difficulty swallowing. Some texts mention throat obstruction and trouble getting food down. This symptom has many serious causes, and it has never been studied as an acupressure target. Treat it as a reason to get examined.
• Local neck tension. Light contact along the front edge of the neck muscle can feel soothing, as touch often does. That is a general comfort effect rather than something specific to ST10.

A fair summary: ST10 is a recognised classical point with a tidy traditional story about the throat, and almost nothing in the way of modern human testing. Where acupressure does have reasonable trial support, it is for other points and other problems, most clearly PC6 at the wrist for nausea and vomiting. ST10 has no comparable record.

We are not telling you it does nothing. We are telling you that nobody has checked, and that the checking matters more than the tradition when the point sits over a major artery.

Are there tips for using ST10 effectively?

• Prefer a safer point. The single most useful tip for ST10 is to choose a different point. For throat and cough complaints, wrist and hand points carry none of the carotid risk and are easier to find accurately.
• Learn the location for safety, not for pressing. Knowing where ST10 is helps you recognise the throat zone to keep heavy hands away from, including during self-massage of the neck and shoulders.
• Always pulse-check first. Make "feel for a beat, then move off it" an automatic habit before any contact on the front of the neck.
• Keep the chin neutral. Do not crane your head back to reach the area. A neutral chin keeps the muscle edge findable and the airway comfortable.
• Short, light, one side. Seconds rather than minutes, feather pressure rather than firm, and never both sides together. If that feels too restrictive to be worth doing, that is a reasonable conclusion.
• Have someone nearby the first time. If you are going to touch this area at all, do it when you are not alone at home.
• Do not use it during an attack. An asthma flare, a choking episode, severe throat pain or a swollen neck is a moment for medical help, not for experimenting on a point.
• Write down what happens. If you track symptoms honestly over a couple of weeks, you will usually see that most throat irritations settle on their own. That is useful context for judging any technique.

One general point about expectations. Acupressure studies that look positive are usually small, short and unblinded, which means the comfort of being touched and the belief that something is being done can account for a lot. That is not worthless, but it is not the same as a specific effect from a specific spot.

What do people get wrong with ST10?

• Pressing the pulse. The commonest and most dangerous error is landing on the carotid artery instead of the muscle edge. Pressure on the carotid sinus can slow the heart and cause fainting, and in older arteries it can dislodge plaque.
• Pressing both sides at once. Squeezing the front of the neck with thumb and fingers, or using both hands together, raises the chance of a sudden blood-pressure drop. Never do this.
• Going deep. People assume that more pressure means more effect and dig in with a knuckle or a massage tool. The throat has no safe margin for that. Light contact or nothing.
• Confusing ST10 with its neighbours. ST9 sits level with the Adam's apple right over the pulse, and ST11 sits just above the inner collarbone. ST10 is the midpoint between them. Mixing them up usually means ending up on the artery.
• Expecting a cure. ST10 will not shrink a goitre, resolve asthma or fix a swallowing problem. No point does that, and nothing on this page promises an outcome.
• Treating a neck lump at home. Pressing on an unexplained lump delays the one thing that helps, which is getting it looked at. Lumps that are new, hard, growing or painless deserve a prompt appointment.
• Using it while unwell or unsteady. Dehydration, fever, a recent faint or new medication all make a pressure-related dizzy spell more likely.
• Working on others. Applying throat pressure to a friend, a child or an older relative removes their ability to feel the warning signs and stop. Do not do it.

If you take one thing from this list: the mistake is almost always too much pressure in the wrong millimetre, and the fix is almost always to stop touching the front of the neck.

What does the research on ST10 actually say?

We found no useful human research on ST10 specifically. There appear to be no controlled trials, and no reliable case series, testing acupressure or any other stimulation at Shuitu for throat pain, cough, wheezing, thyroid swelling or anything else.

That absence is worth stating plainly rather than filling with something borrowed. Some neck points have attracted attention in blood-pressure research, but that work concerns other points and other methods, and it would be dishonest to transfer those findings onto ST10. We will not invent a citation to fill the gap.

What the wider field looks like gives useful context. Acupressure research overall is dominated by small studies, often with few participants, no credible sham comparison and follow-up measured in days. Where the evidence is genuinely decent, it is point-specific and symptom-specific: PC6 at the wrist for nausea and vomiting is the clearest example in the whole literature, supported by multiple controlled trials. ST10 has nothing of that kind behind it.

There is also a physiology literature that is relevant to safety rather than benefit. Doctors know that pressure on the carotid sinus in the neck can slow the heart and drop blood pressure, which is why this is performed as a monitored medical manoeuvre and not as self-care. That knowledge is the main reason we treat ST10 as a locate-and-avoid point.

What this means for you is simple. Any claim that ST10 treats a thyroid condition, an asthma diagnosis or high blood pressure is unsupported by human trials. If a source states such a thing confidently, that is a reason to doubt the source. Keep using your prescribed treatment, and raise neck or breathing symptoms with a clinician who can examine you.

If good trials on this point appear, we will update the page and the evidence grade. Until then, the honest grade is insufficient.
