Guanmen

What is ST22?

ST22 (Guanmen) is a Stomach channel point on the upper belly, about four finger-widths above the navel and three finger-widths out to the side.

Its Chinese name, Guanmen, is usually translated as "Gate Pass" or "Pass Gate". Classical texts group it with the run of Stomach channel points that march down the front of the abdomen, and they link it to digestion, bloating and bowel movements.

In tradition it is a secondary point rather than a headline one. Teachers reach far more often for ST25 beside the navel or ST36 below the knee. ST22 tends to appear as a local helper when the complaint sits high in the belly.

Two things are worth saying once, up front. First, a long traditional history is not evidence that a point works; it tells you what practitioners believed, not what a trial measured. Second, that history is not evidence that a point is safe either. ST22 sits over the abdominal wall, and the abdomen is one place where pressing hard can genuinely be the wrong idea for some people.

The honest verdict on evidence: there is essentially no human research on ST22 by itself. Acupressure research in general is dominated by small, short and unblinded studies, and the few strong results in the field belong to other points, most famously PC6 for nausea. Nothing comparable exists for ST22.

What this page offers is a clear, conservative description of where ST22 is, what tradition claims for it, how to press it with a fingertip, and who should keep their hands off it. Everything here is self-applied finger pressure. Nothing on this page involves needles, heat therapy or anything that breaks the skin.

If gentle pressure on your upper belly feels soothing after a heavy meal, that is a reasonable thing to enjoy. It is not a treatment for a digestive disease, and it should never delay a proper look at symptoms that are new, severe or getting worse.

Where is ST22 and how do you find it?

Find ST22 on the upper abdomen, roughly 7-8 cm above the centre of the navel and about 5 cm out to the side, over the firm band of belly muscle.

• Start at your navel. Put one fingertip in the middle of your belly button. Every measurement for ST22 is taken from this point, so get it central before you move.
• Measure straight up. Classical sources put ST22 three cun above the navel. On your own body that is about four finger-widths, measured with your fingers held together, or roughly 7-8 cm for most adults. That upper level sits about halfway between the navel and the lower tip of the breastbone.
• Move out to the side. From that upper midline spot, slide about two cun sideways. That is roughly three finger-widths, or about 5 cm. Do this on either the left or the right; ST22 is a paired point, so there is one on each side.
• Feel for the muscle ridge. ST22 lies over the rectus abdominis, the straight belly muscle. Tense your stomach for a second and you may feel a firm vertical band under your fingers. The point sits on that band, not out in the soft flank.
• Check the feel. Under relaxed, gentle pressure the area should feel like soft tissue over muscle, with a mild dull ache at most. It should never feel sharp, and you should not be pressing into a hard lump or a pulsing spot.

Bodies vary, so use your own hand for the measuring rather than a ruler. Tall people measure larger, children measure smaller. If your fingers land a centimetre off, you are still in the broad area tradition means.

One common mix-up: ST25 sits level with the navel, not above it. If your finger ends up beside the belly button, you have found ST25, not ST22.

How do you apply pressure to ST22?

1. Pick a calm moment. Wait at least an hour or two after a full meal. Pressing a stuffed stomach is uncomfortable and can bring on reflux.
2. Lie down and bend your knees. Lying on your back with knees up lets the abdominal wall go soft. A tense belly makes the point hard to feel and tempts you to push harder.
3. Warm your hands. Rub your palms together for a few seconds. Cold fingertips on bare abdominal skin make the muscles guard.
4. Use flat finger pads. Place the pads of your index and middle finger on ST22. Use the soft pad, never a fingernail, knuckle or any hard object.
5. Sink in slowly on an out-breath. Let pressure build over three or four seconds as you exhale. Aim for about three or four out of ten on a discomfort scale: noticeable, dull, entirely bearable.
6. Hold or circle gently. Either hold steady for 30 to 60 seconds, or make small slow circles that move the skin with your finger rather than rubbing across it.
7. Release slowly and swap sides. Ease off over a couple of seconds, then repeat on the other side so both sides get equal attention.
8. Repeat sparingly. Two or three rounds per side, once or twice a day, is plenty. More pressure and more repetitions do not buy a better result.

Stop immediately if the pressure is sharp, if it makes you feel sick, or if it reproduces a pain you were already worried about. Stop too if the skin reddens and stays sore afterwards.

Keep a light touch if you bruise easily, take blood-thinning medicine, or have thin or fragile skin. On the abdomen, gentle really is enough.

This is finger pressure only. Nothing here involves needles, burning herbs, suction cups or any tool that pierces or marks the skin.

What is ST22 traditionally used for?

• Bloating and upper belly fullness. The classical headline use. Texts describe ST22 for abdominal distension and that tight, overfull feeling after eating. No controlled human trial has tested ST22 for this, so the claim rests on tradition and personal report alone.
• Loose stools and diarrhoea. Tradition pairs ST22 with watery stools and gurgling in the gut. Some acupressure studies look at bowel symptoms, but they use other points and bundled protocols, so nothing can be credited to ST22 specifically.
• Poor appetite. Older sources list ST22 for not wanting to eat and for food that seems to sit undigested. There is no human evidence testing whether pressing this point changes appetite.
• Nausea and the urge to vomit. ST22 is sometimes mentioned for stomach upset that rises upward. It is worth being clear here: the point with genuinely good human trial evidence for nausea is PC6 on the inner wrist, not ST22. If nausea is your problem, PC6 is the better-supported place to start.
• Abdominal pain and cramping. Tradition uses ST22 as a local point for discomfort in the upper abdomen. Warm, gentle pressure on a sore belly is a comfort measure many people find pleasant, but comfort is not the same as treating the cause.
• Swelling and fluid retention. Some classical lists include oedema among its indications. This claim has no modern support at all, and swelling that is new or one-sided needs a doctor rather than a fingertip.

Taken together, the traditional picture is consistent: ST22 is a local digestive point. The modern picture is thin. Treat anything you feel as a personal, short-term response rather than proof the point does what the old books say.

Nothing here is a cure, and ST22 should not replace medicine, tests or dietary advice you have been given for a diagnosed condition.

Are there tips for using ST22 effectively?

• Time it away from meals. One to two hours after eating is the sweet spot. A full stomach makes abdominal pressure uncomfortable and can push acid upward.
• Let the breath do half the work. Press as you breathe out, ease as you breathe in. Slow breathing relaxes the abdominal wall, which makes a light touch feel like enough.
• Warmth beats force. A warm hand or a warm (not hot) cloth over the area before you start often does more for comfort than pressing harder. Never use anything hot enough to redden skin.
• Work both sides. ST22 is paired. Treating one side only leaves the routine feeling lopsided, and there is no tradition of favouring a single side here.
• Keep sessions short. A minute or two per side is a full session. Long grinding pressure on the abdomen tends to leave soreness rather than relief.
• Stay on the muscle band. Drifting outward into the soft flank takes you off ST22 entirely. A quick tense of the belly helps you relocate the firm vertical band.
• Write down what actually happened. Note the date, how you felt before and after, and what else changed that day. Bloating comes and goes on its own, so a simple log keeps you honest about whether anything shifted.
• Fix the obvious things first. Meal size, eating speed, fizzy drinks, alcohol and sleep move digestive symptoms far more reliably than any pressure point. Use ST22 alongside those changes, not instead of them.
• Treat it as comfort, not treatment. If you enjoy it, keep it as a two-minute wind-down habit. If a week or two brings no change at all, there is no reason to keep forcing it.

If you are also using ST22 for nausea, be aware the better-studied option is PC6 at the inner wrist. There is no harm in using both, but expect more from the one with actual trial support.

What do people get wrong with ST22?

• Expecting a cure. The biggest error. ST22 will not resolve reflux, an ulcer, gallstones, coeliac disease or irritable bowel syndrome. Treating it as a fix can delay a diagnosis that matters.
• Confusing it with ST25. ST25 sits level with the navel; ST22 sits roughly four finger-widths higher. People measure sideways from the belly button, land on ST25, and then wonder why videos describe a different feeling.
• Pressing far too hard. The abdomen has no bone underneath to protect the organs. Digging in with a knuckle or thumb tip can leave you sore for days and gains nothing.
• Working on a full stomach. Pressing straight after a big meal often causes burping, reflux or queasiness. Wait an hour or two.
• Ignoring red-flag pain. Severe, sudden or steadily worsening belly pain is a reason to call a doctor, not a reason to press a point. The same goes for pain with fever, vomiting or a rigid, board-like belly.
• Pressing over something that should not be pressed. A fresh surgical scar, a hernia bulge, a stoma, a feeding tube, broken skin or an unexplained lump all mean hands off that area completely.
• Pushing through sharpness. Dull and bearable is the target. Sharp, stabbing or radiating pain means stop, not persevere.
• Assuming old equals proven. ST22 appears in classical texts, which tells you it was used, not that it works. Tradition and evidence are separate questions.
• Dropping medication. Some people stop antacids or prescribed treatment to "test" the point. Never change prescribed medicine without speaking to the person who prescribed it.
• Overdoing frequency. Twelve sessions a day does not multiply any effect. It mostly produces a tender abdominal wall.

What does the research on ST22 actually say?

There is no useful human research on ST22 specifically. No controlled trial that we can point to has tested finger pressure on Guanmen for bloating, diarrhoea, appetite or abdominal pain as a named, isolated intervention.

What exists instead is research on acupressure and acupuncture in general for digestive complaints. Those studies almost always use multi-point protocols built around better-known points such as ST36 below the knee, ST25 beside the navel, CV12 on the midline and PC6 at the wrist. Even when a protocol happens to include abdominal points, the design cannot separate out what any single point contributed.

The quality of that broader literature is modest. Reviews of acupressure repeatedly describe small groups of participants, short follow-up, and trials where people knew which treatment they were receiving. Unblinded studies of a symptom as subjective as bloating are especially prone to flattering results. That does not mean the field is worthless, but it does mean weak findings should not be read as proof.

Some published trials of acupuncture and related techniques do needle abdominal Stomach channel points. Reporting that is simply describing what those trials did; it is not something a reader should attempt, and nothing on this page involves needles or skin penetration.

The one genuinely strong result in the wider acupressure literature belongs elsewhere. PC6 for nausea and vomiting, including after surgery and in pregnancy, has been tested in many controlled trials and supported by systematic reviews. That is the standard worth remembering when you read confident claims about other points, because ST22 is nowhere near it.

Practically, this means you should treat ST22 as an untested comfort habit. If gentle pressure on your upper belly feels good, that is a real experience and worth nothing more or less than it is. If a digestive symptom is persistent, severe or new, the useful next step is a doctor who can examine you, not more pressure.
