Daju

What is ST27?

ST27 (Daju) is an acupuncture point on the lower belly, about two thumb-widths below the navel and two thumb-widths out to the side.

Its pinyin name, Daju, is usually translated as Great Giant. It sits on the Stomach channel, which in Chinese medicine runs down the front of the trunk. Classical texts link ST27 to fullness in the lower abdomen, difficult urination, hernia and various reproductive complaints.

In teaching terms ST27 is a standard, named point that most curricula list, but it is not one of the headline points. Practitioners reach for it far less often than they reach for nearby ST25 or the midline points.

The honest verdict on evidence is short. No useful human trial has tested finger pressure on ST27 for any condition. Almost everything written about it comes from tradition and from practitioner habit, not from measurement.

Two things are worth stating plainly, and this page states them once here rather than at the top of every section. First, long traditional use is not evidence that a point works. Second, long traditional use is also not evidence that a point is safe for you, because the belly covers organs, blood vessels and surgical scars that a classical text never considered. Safety on this page comes from anatomy and common sense, not from pedigree.

Everything described here is self-applied finger pressure. This library does not teach needling, moxibustion or cupping, and nothing on this page should be read as instruction for them. If research on this point involved needles, that is reported as what the researchers did.

Where is ST27 and how do you find it?

ST27 sits on the lower abdomen, two thumb-widths straight down from the centre of the navel, then two thumb-widths out to the side.

• Start at the navel. Lie on your back with your knees bent and your belly relaxed. Put one fingertip in the centre of your navel as your reference mark.
• Measure downwards. Move down the midline by about two thumb-widths, roughly 4 to 5 cm on most adults. In traditional terms this is 2 cun below the navel, level with the midline point CV5.
• Measure sideways. From that midline spot, move out to the side by another two thumb-widths, about 4 to 5 cm. Stay on the same horizontal line.
• Check the muscle. You should now be over the bulk of the rectus abdominis, the vertical strap muscle that stands out if you lift your head off the pillow. ST27 sits on that muscle, not on the midline gap between the two sides.
• Feel for the response. Press slowly with a flat fingertip. Many people notice a dull, slightly heavy or tender feeling rather than a sharp one. Soreness is a rough guide only, not proof you are in the right place.

Use your own thumb as the ruler, not someone else is. A thumb-width is measured across the widest part of the thumb at the knuckle, and it scales with the person.

ST27 is paired, so there is one on the left and one on the right. Its immediate neighbours on the same vertical line are ST26 one thumb-width above it and ST28 one thumb-width below it, which is why careless measuring lands you on the wrong point. Never state or seek a needle depth here; this page describes surface pressure only.

How do you apply pressure to ST27?

1. Lie down first. Rest on your back with knees bent and feet flat. A relaxed belly lets your fingers sink in gently. Pressing a braced, upright abdomen is uncomfortable and tells you little.
2. Warm your hands. Rub your palms together for a few seconds. Cold hands on a cold belly tend to make the muscles tense up, which makes the point harder to feel.
3. Use flat finger pads. Place the pads of your index and middle fingers on ST27. Keep nails short and avoid poking with a single fingertip or a knuckle.
4. Press slowly and gently. Sink in over three or four seconds until you feel mild pressure or a dull ache. On the abdomen, light is enough. You should never need to dig.
5. Hold and breathe. Hold for 30 to 60 seconds, breathing out as you press in. Small slow circles are an option if static pressure feels dead.
6. Do both sides. Treat the left and right points for the same length of time, either one after the other or together.
7. Repeat sensibly. One to three short sessions a day is plenty. A session of a few minutes is more than enough; longer is not better.
8. Release gradually. Lift your fingers over a couple of seconds rather than snapping them away, then rest for a minute before standing.

Stop immediately if you feel sharp, stabbing or spreading pain, nausea, dizziness, or pain that lingers after you let go. Stop too if you feel anything pulsing strongly under your fingers, or any lump or bulge you cannot explain.

Leave at least an hour after a large meal, and do not press hard on a very full bladder. If a point is still tender the next day, give it several days off.

What is ST27 traditionally used for?

• Lower abdominal fullness. The most consistent classical use of ST27 is for distension, bloating and a heavy, dragging feeling low in the belly. No human trial has tested finger pressure on ST27 for bloating, so this rests on tradition and on the general comfort of a warm hand on the abdomen.
• Difficult or uncomfortable urination. Old texts list ST27 for dysuria, meaning painful or hesitant urination. There is no trial evidence behind this. Urinary symptoms that are new, painful or bloody need a medical assessment, not a pressure point.
• Hernia and groin dragging. Classical sources mention ST27 for what they called shan disorders, a broad group that included hernia and lower abdominal pain. This is a historical category, not a modern diagnosis, and a real hernia is a structural problem that pressure cannot correct.
• Reproductive complaints. Tradition links ST27 to seminal emission, impotence and irregular periods. These claims are not supported by any controlled human study of this point, and several of them have effective modern treatments worth asking about.
• Constipation and sluggish bowels. Some practitioners include ST27 in abdominal routines for bowel discomfort. Trials of abdominal massage for constipation exist and are mildly encouraging, but they test whole-hand massage over a region rather than this single point.
• Tension held in the belly. Slow self-massage of the abdomen while lying down is calming for many people. That effect is plausible and non-specific; it is not something ST27 can be credited with on its own.

Across the board, the realistic picture is modest, short-lived comfort at best. Any claim that ST27 corrects an organ problem, clears an infection or restores fertility goes well past what anyone has shown.

Are there tips for using ST27 effectively?

• Measure before you press. Find the navel, count two thumb-widths down and two across, then press. Hunting blindly for a sore spot usually lands you on ST26 or ST28 instead.
• Keep it light on the belly. Abdominal tissue is soft and there is no bone behind it. Gentle, steady pressure is appropriate here, and heavy force adds risk without adding benefit.
• Empty your bladder first. This is directly over the lower abdomen. A comfortable bladder makes the session easier and avoids unnecessary pressure.
• Exhale into the press. Pressing as you breathe out lets the abdominal wall soften. Holding your breath stiffens exactly the muscle you are resting on.
• Work both sides evenly. ST27 is a paired point. Treating only one side is a common shortcut and leaves the routine lopsided.
• Pick a calm moment. Evening, after a bath, or any time you can lie flat for five minutes works better than a rushed press at a desk.
• Keep a simple log. Note the date, how long you pressed and how you felt an hour later. Two weeks of notes will tell you more about whether it helps you than any article can.
• Treat it as an add-on. Use ST27 alongside your prescribed treatment, fibre, fluids, movement or physiotherapy, not instead of them.
• Give it a fair but limited trial. If a fortnight of regular, gentle use changes nothing, that is a useful answer. Stop and spend the time on something with better support.

What do people get wrong with ST27?

• Expecting a cure. Some videos present ST27 as a fix for fertility, hernia or urinary disease. No acupressure point does that, and believing it delays real care. Expect modest comfort at most.
• Digging in hard. People press the abdomen as if it were a shoulder knot. There is no bone underneath to brace against, so hard pressure just bruises tissue and makes the area sore.
• Landing on a neighbour. ST26 sits one thumb-width above and ST28 one thumb-width below, on the same line. Guessing instead of measuring from the navel usually means you are on one of them.
• Drifting to the midline. ST27 is two thumb-widths out to the side, over the muscle. Sliding inwards puts you on the midline Conception Vessel points instead.
• Pressing a full stomach. Working the lower abdomen straight after a big meal is uncomfortable and can bring on reflux or nausea. Wait at least an hour.
• Ignoring a bulge. If a soft lump appears or disappears when you cough or strain, that may be a hernia. Pressing on it is the wrong response; getting it examined is the right one.
• Using it during pregnancy. Lower abdominal pressure is not appropriate in pregnancy, and tradition avoids this region too. Many people only check this after they have started.
• Chasing tenderness. A sore spot is not proof of a correct point. Tenderness in the lower belly can come from muscle strain, bowel or bladder, and it deserves attention rather than repeated pressing.
• Skipping the doctor. Blood in the urine, burning on passing water, severe pain or a fever are medical problems. No point on the belly is a substitute for assessment.

What does the research on ST27 actually say?

There is no useful human research on ST27 specifically. No controlled trial of finger pressure on this point for bloating, urinary symptoms, hernia or reproductive complaints could be identified, and no case series worth reporting either.

That is not unusual. The acupuncture and acupressure literature concentrates on a small handful of heavily studied points, such as PC6 for nausea and vomiting, which has genuine controlled human trials behind it. ST27 is not among the studied points. Where it does appear in research, it is usually one name inside a list of needled abdominal points in a multi-point protocol, alongside points like ST25 and midline Conception Vessel points. A trial built that way cannot tell you what ST27 contributed, because nothing in the design separates it out.

Nearby work offers only weak, indirect support. Trials of general abdominal massage for constipation suggest small benefits, but they test broad whole-hand massage over the belly rather than pressure on one named point. Reading those results as proof for ST27 is a stretch.

What this absence means in practice is simple. It does not prove ST27 does nothing; it means nobody has measured it properly. Any confident numbers you see quoted for this point, such as percentages of people helped, are not coming from published evidence on ST27.

Treat gentle self-pressure here as a low-cost comfort measure with an unknown effect. If a symptom matters enough to look up a pressure point for it, it is worth mentioning to a clinician as well, because there may be a treatment with real evidence behind it.
