Wailing

What is ST26?

ST26 (Wailing) sits on the lower abdomen, about 2.5 cm below the centre of the navel and about 4 cm out to the side.

It is the twenty-sixth point on the Stomach channel, one of a vertical row of abdominal points that runs down from the ribs to the groin. Its Chinese name, Wailing, is usually translated as Outer Mound, a reference to the soft bulge of the abdominal muscle beside the midline. Classical texts group it with its neighbours for complaints of the lower belly: cramping pain, dragging or hernia-type pain, and painful periods.

ST26 is taught in standard point curricula, but it is not one of the headline points practitioners reach for every day. In practice it tends to be used alongside ST25 and ST27 rather than on its own.

The honest verdict on evidence: there is essentially none for ST26 specifically. We found no controlled human trials testing finger pressure on this point for any condition. What exists is research on nearby abdominal points, using needles or electrical stimulation in clinics, which does not tell you what your own thumb will do at home.

Two things are worth saying clearly once, here, rather than repeating on every section below. First, a long traditional record is not evidence that a point works; people have used ST26 for centuries without anyone running the trials that would settle the question. Second, tradition is not evidence that a point is safe either. The lower abdomen sits over the bowel, the bladder and, in pregnancy, the uterus, so the cautions on this page are about anatomy, not about old texts.

Use this page to find the point, press it sensibly, and know when pressing is the wrong answer altogether.

Where is ST26 and how do you find it?

ST26 lies on the lower abdomen, one thumb-width below the centre of the navel and about two thumb-widths out to either side of the midline.

• Lie down first. Rest on your back with your knees bent and feet flat. This softens the abdominal wall and makes the landmarks easier to feel.
• Start at the navel. Put one fingertip in the centre of your navel. This is your reference point for the whole lower abdomen.
• Drop down one thumb-width. Move straight down the midline by the width of your own thumb at the knuckle, roughly 2 to 2.5 cm. In traditional terms this is 1 cun below the navel, level with the point CV7.
• Move out to the side. From that midline spot, slide sideways about two thumb-widths, roughly 4 to 5 cm. That is 2 cun lateral to the midline. ST26 exists on both the left and the right.
• Check the muscle. You should be over the soft belly of the rectus abdominis, the vertical muscle either side of the midline. If you tense your stomach gently, you can feel that muscle firm up under your fingers.
• Feel for the response. Many people notice a slightly tender or heavy spot within a centimetre of the measured position. Use that as your working point.

Measure with your own hand, not someone else's. Cun are proportional, so a tall person's thumb-width is genuinely wider than a small person's, and that is the intended behaviour.

A common mix-up is worth flagging. ST25 (Tianshu) is level with the navel itself, and ST27 (Daju) is two thumb-widths below it. ST26 sits between them. If your finger is level with the navel, you have found ST25, not ST26.

How do you apply pressure to ST26?

1. Get comfortable. Lie on your back with knees bent, or sit well back in a chair. A relaxed abdominal wall lets you reach the point without forcing.
2. Warm your hands. Rub your palms together for a few seconds. Cold fingertips on the belly make most people tense up.
3. Use flat finger pads. Place the pads of your index and middle fingers on the point. Do not use a fingernail, a knuckle or a massage tool on the abdomen.
4. Press on the out-breath. Breathe out slowly and sink in as the belly softens. Pressing against a held breath is uncomfortable and achieves nothing.
5. Keep it gentle. Aim for about 3 or 4 out of 10 pressure, where 10 is the most you could bear. You want a dull, warm ache, never a sharp or sickening pain.
6. Hold or circle. Either hold steady for 30 to 60 seconds, or make small slow circles for the same time. Then ease off gradually rather than lifting suddenly.
7. Do both sides. Treat the left and the right point, either one after the other or both at once with one hand on each.
8. Repeat sensibly. Two or three short sessions a day is plenty. There is no benefit in grinding away for twenty minutes.

Stop straight away if the pain sharpens, if you feel nauseous or faint, if the area throbs after you finish, or if you feel a lump or a pulsing mass under your fingers. Stop also if pressing makes you need to pass urine urgently or uncomfortably.

Timing helps. Leave an hour after a large meal, and empty your bladder first. Never press hard enough to leave a bruise, and never continue on skin that is red, broken or already sore.

What is ST26 traditionally used for?

• Lower abdominal cramping. The main traditional use of ST26 is pain and griping below the navel. There are no trials of finger pressure on ST26 for this. Gentle self-massage of the abdomen is low risk and some people find it settling, which is a different claim from it working.
• Period pain. Classical sources list ST26 for painful periods and lower belly pain around menstruation. Human research on acupressure for period pain exists, but the trials almost always use SP6, LI4 or ear points, not ST26. Those studies are mostly small and unblinded, so they cannot be stretched to cover this point.
• Bloating and a sluggish gut. Tradition links the abdominal Stomach points to digestion and bowel movement. Slow, gentle abdominal massage has some supportive evidence for constipation in general, but that evidence is about massaging the belly as a whole, not about pressing one named point.
• Hernia-type dragging pain. Old texts list ST26 for what they called shan disorders, a group of groin and lower belly complaints that includes hernia. A real hernia is a structural problem and needs assessment; pressure is not a treatment for it and can hurt.
• Tension in the belly wall. Some people simply find the area tight and sore and feel better after working it gently. That is a plausible soft-tissue effect and does not require any channel theory to explain.

Taken together, ST26 has a clear traditional role and almost no point-specific human evidence. Treat any relief you get as a comfort measure, not as treatment of the underlying cause.

Are there tips for using ST26 effectively?

• Measure on yourself. Use your own thumb-width for the cun measurement on ST26, not a figure copied from a video. Body proportions differ, so a borrowed measurement lands in the wrong place.
• Let the tenderness guide you. If a tender spot sits a centimetre from where you measured, work the tender spot. Traditional location is a starting map, not a target you must hit exactly.
• Soften the belly first. Knees bent, shoulders down, a few slow breaths. A guarded abdomen resists pressure and the session becomes a wrestling match.
• Add warmth, not fire. A warm pack or a hot water bottle over the lower abdomen before you press is pleasant and safe. Do not use burning herbs or anything that touches hot material directly to skin.
• Work both sides evenly. ST26 is paired. Doing one side only tends to leave the abdomen feeling lopsided and tight.
• Pick a consistent time. Evening, after a bath, away from meals, suits most people. Regular short sessions are easier to keep up than occasional long ones.
• Give it two weeks, then judge. Note your symptom level before and after each session for a fortnight. If nothing has shifted, stop rather than adding more pressure.
• Combine with the basics. Fluid intake, fibre, movement and sleep do more for most lower abdominal complaints than any point. Acupressure sits on top of those, not instead of them.
• Keep nails short. Long nails on soft abdominal skin cause scratches and small cuts, which is how a harmless session becomes a sore one.

What do people get wrong with ST26?

• Expecting a cure. ST26 will not resolve endometriosis, a hernia, irritable bowel syndrome or fibroids. Pressing a point is a comfort measure at best, and treating it as a treatment delays real answers.
• Confusing it with ST25. ST25 is level with the navel; ST26 is one thumb-width below. Most people who think they are using ST26 are actually on ST25, because that is the point videos show.
• Pressing far too hard. The abdomen is not the shoulder. Digging deep into soft tissue can bruise, aggravate cramps and, over the bowel, simply hurt. Gentle and steady beats forceful every time.
• Pressing through unexplained pain. New, severe or one-sided lower abdominal pain is a reason to be examined, not a reason to massage harder. Appendicitis and ovarian problems both start as belly pain.
• Using it in pregnancy anyway. Lower abdominal points are traditionally avoided in pregnancy, and the anatomy alone is reason enough. A video that omits this is not giving you permission.
• Working on a scar too soon. People who have had a caesarean, hernia repair or laparoscopy often press right over healing tissue. Wait until your surgeon clears the area.
• Copying needle technique. Studies on abdominal points usually use needles or electrical stimulation in a clinic. Nothing on this page, and nothing you see online, makes skin-breaking technique a home activity.
• Doing it right after eating. Pressure on a full stomach is uncomfortable and sometimes makes reflux worse. Leave an hour.
• Chasing intensity. If a short gentle session does nothing, a long hard one will not do more. It just makes you sore.

What does the research on ST26 actually say?

There is essentially nothing. We found no controlled human trials testing ST26 specifically, and none at all testing finger pressure on ST26 for abdominal pain, period pain or digestive symptoms. That is the honest position, and it is the usual position for individual points away from the small handful that have been studied properly.

Some research exists on the abdominal Stomach points as a group, most of it on ST25 (Tianshu) rather than ST26. Trials of electroacupuncture at abdominal points for chronic constipation and for irritable bowel syndrome have been run, mainly in China, and some reported improvements in stool frequency. Those studies used inserted needles with electrical stimulation, delivered by practitioners over many sessions. They tell you little about pressing a neighbouring point with your thumb for a minute.

It is worth knowing how weak most acupressure evidence is in general. Trials tend to be small, short, and unblinded, meaning participants knew they were being treated. Outcomes like pain and bloating are self-reported and respond strongly to attention and expectation. That combination inflates apparent benefit. The clearest exception in the whole field is PC6 for nausea and vomiting, which has genuine supportive trial evidence. ST26 is nowhere near that standard, and no honest page should imply otherwise.

What that absence means in practice is simple. Nobody can tell you that ST26 works, and nobody can tell you how much it would help if it did. It also means the safety data is thin, so the cautions on this page come from anatomy and common sense rather than from trial reports of harm.

If you use ST26, use it as a low-cost, low-risk comfort habit. Judge it on your own experience over a couple of weeks, and keep investigating any symptom that is new, worsening or unexplained.
