Shangqu

What is KI17?

KI17 (Shangqu) is a Kidney-channel point on the upper abdomen, about two thumb-widths above the navel and a half-thumb to the side of the midline.

Its Chinese name is usually translated as "Shang Bend" or "Commerce Bend", a reference to the musical note shang and to the curve of the bowel beneath it. Classical texts group it with the other Kidney abdominal points, KI16 through KI21, which run in a short vertical line up from the navel to the ribs. It is also listed as a meeting point of the Kidney channel with the Chong vessel, one of the eight extraordinary vessels.

Tradition uses KI17 almost entirely for digestive complaints: abdominal pain, rumbling, constipation, loose stools and poor appetite. On this page we only ever describe gentle finger pressure on the skin.

Two things are worth saying once, clearly, before you read further. First, the fact that a point has been taught for two thousand years is not evidence that pressing it does anything measurable. Second, long tradition is not evidence that it is safe for you in particular, because the people who wrote those texts were not looking at your abdomen, your pregnancy or your recent surgery.

The honest verdict on evidence: there is essentially no human research testing KI17 on its own for any condition. Acupuncture and acupressure trials that include it almost always use it inside a combination of five or ten points, so nothing can be attributed to this point specifically. That is different from saying it does nothing — it means nobody has looked properly. For comparison, PC6 and nausea has dozens of controlled trials behind it; KI17 has nothing of that kind.

What gentle abdominal pressure reliably offers is a few minutes of slow breathing and warmth over the belly, which many people find settling. Treat that as the realistic ceiling, not a cure for a gut problem.

Where is KI17 and how do you find it?

KI17 sits on the abdomen two thumb-widths straight up from the centre of your navel, then a half-thumb-width out to the side.

• Start at the navel. Put one fingertip in the middle of your belly button. This is your only reliable landmark on a soft abdomen, so everything is measured from it.
• Measure up two cun. Two cun is the width of your own thumb at the knuckle doubled — roughly 4 to 5 cm (about 1.5 to 2 inches) for most adults. Move straight up the midline by that amount.
• Find the midline. The midline is the faint vertical groove running from the navel to the base of your breastbone. If you tense your stomach, you can feel the gap between the two straps of muscle either side.
• Step out a half-thumb. From the midline, move about 1 to 1.5 cm (half an inch) to the left or right. KI17 is a paired point, so there is one on each side.
• Check what is under your finger. You should be on soft abdominal wall, not on the hard edge of the rib cage and not in the navel itself. Firm, slow pressure often feels slightly fuller or more tender than the skin a few centimetres away.

Use your own hand for the measuring, not a ruler. Cun are proportional, so a tall person's two cun is genuinely longer than a short person's.

If you are not confident, stay conservative. What everyone agrees on is that KI17 is on the upper abdomen, above the navel and very close to the midline. Pressing a slightly imprecise spot with a soft flat finger is harmless on a healthy belly; digging hard into an exact spot is not. There is no needling instruction anywhere on this page and you should never attempt one at home.

How do you apply pressure to KI17?

1. Pick a calm moment. Avoid the hour straight after a large meal, when the stomach is full and pressure feels uncomfortable. Empty your bladder first.
2. Lie down with knees bent. Lying on your back with your feet flat and knees up lets the abdominal wall soften. A tense belly makes the point almost impossible to feel.
3. Warm your hands. Rub your palms together for a few seconds. Cold fingers on the stomach make people flinch and tighten up.
4. Use flat finger pads. Place the pads of your index and middle fingers on the point — never a fingernail, a knuckle or a hard massage tool. The abdomen has no bone protecting it.
5. Press gently and slowly. Sink in over three or four seconds until you feel mild, even pressure. It should rate about 3 out of 10 for discomfort. Sharp pain means stop, not push harder.
6. Hold and breathe. Keep the pressure steady for 30 to 60 seconds while breathing slowly through your nose. Let your belly rise into your fingers on each in-breath rather than bracing against them.
7. Release slowly. Lift off over a couple of seconds. A quick release on a sore abdomen can feel unpleasant.
8. Repeat sensibly. Two or three holds on each side, once or twice a day, is plenty. Small circles with light pressure are an alternative to a static hold.

Stop immediately and do not continue if you feel sharp pain, a pulsing lump under your fingers, nausea that worsens, or pain that spreads to your back or shoulder. Stop also if the skin reddens and stays sore afterwards.

Keep sessions short. Working an abdominal point for ten minutes does not make it more effective; it just bruises soft tissue. If nothing has changed after a week or two of sensible use, the point is unlikely to be the answer for you.

What is KI17 traditionally used for?

• Abdominal pain and cramping. This is the main classical use, usually described as pain around the navel with fullness. No controlled human trial has tested KI17 alone for abdominal pain, so this rests on tradition and on the general comfort of warm, slow pressure on a tense belly.
• Constipation. Old texts list KI17 for difficult or dry stools. Abdominal massage as a whole has modest trial support for constipation, particularly in older adults and in people with neurological conditions, but those studies massage the whole belly rather than this one point. KI17 cannot claim that evidence for itself.
• Diarrhoea and loose stools. Tradition treats KI17 as useful in both directions, which is common for abdominal points and is a sign the claim is broad rather than specific. There is no human evidence for this use.
• Rumbling and bloating. Borborygmus — audible gut rumbling — appears in classical indications for this point. Evidence is absent; mild bloating is also extremely common and often settles on its own, which makes self-assessment unreliable.
• Poor appetite and indigestion. Listed in several point manuals alongside the neighbouring Kidney abdominal points. Again nothing specific has been tested in people.
• Gynaecological complaints. Because KI17 is described as meeting the Chong vessel, some texts extend it to menstrual pain and infertility. This is a theoretical link within the tradition, not a finding, and the infertility claim in particular should be treated with real caution.

A fair summary: KI17 is a digestive point in tradition, with no point-specific human evidence behind any of these uses. The grade on this page is "insufficient" for that reason, not because the point has been tested and failed.

If a symptom on this list is new, severe, or has lasted more than a couple of weeks, treat it as something to get looked at rather than something to press.

Are there tips for using KI17 effectively?

• Soften the belly first. Lie back with knees bent and take three slow breaths before you touch the point. A braced abdominal wall hides the spot and makes pressure feel sharper than it is.
• Measure with your own thumb. Cun are proportional to your body, so borrowing a partner's hand or a fixed centimetre figure from a video will put you in the wrong place.
• Work both sides. KI17 is paired. Most people do one side then the other, or both at once with two hands, which is easier when lying down.
• Let the breath do half the work. Hold steady pressure and let your belly push into your fingers on the in-breath. This gives a rhythmic, gentle stretch instead of a constant dig.
• Add warmth, not heat. A warm hand or a covered hot water bottle over the area beforehand is pleasant and safe. Never apply a heat source hot enough to redden skin, and never use burning herbs on yourself.
• Keep a short note. Write down the symptom score before and after for a week. Without notes, memory flatters whatever you have just spent time doing.
• Pair it with the boring basics. For constipation, fluid, fibre and walking have far better evidence than any single point. Use KI17 as an addition, never as a replacement.
• Keep sessions short. One or two minutes per side is enough. Longer sessions mostly produce sore skin.
• Stop if it stops being comfortable. Mild tenderness is normal; sharp, spreading or lingering pain is a signal to leave the abdomen alone.

One honest expectation-setter: if KI17 does anything for you, it will be a small, short-lived easing of discomfort, noticed during or shortly after the session. Anything that sounds bigger than that is a claim nobody has earned.

What do people get wrong with KI17?

• Expecting a cure. The commonest error by far. No acupressure point resolves chronic constipation, IBS or a gynaecological condition, and KI17 has no trials behind it at all.
• Measuring too far out. The Kidney abdominal points sit only about half a thumb-width from the midline. People routinely land two or three centimetres out, which puts them over the Stomach channel instead.
• Measuring from the wrong start point. The two cun is measured from the centre of the navel, not from the bottom of the breastbone or the top of the pubic bone.
• Pressing far too hard. There is no bone under the upper abdomen. Digging in with a knuckle or a wooden tool can bruise and in rare cases hurt an organ. Flat finger pads only.
• Working on a full stomach. Pressing hard above the navel just after a meal often causes reflux or queasiness.
• Pressing through new or severe pain. Abdominal pain can mean appendicitis, gallstones, obstruction or something worse. Massaging it delays a diagnosis that may matter.
• Ignoring a pulsing lump. Anything that beats under your fingers in the midline should never be pressed. Lift off and get it checked.
• Using it in pregnancy because tradition says so. Several classical texts caution against abdominal points in pregnancy, and modern safety sense agrees. Do not press KI17 on a pregnant abdomen.
• Trying needles or burning herbs at home. Some videos blur the line between self-massage and clinical acupuncture. Nothing on this page involves breaking skin, and you should not attempt it.
• Dropping real treatment. Using KI17 instead of prescribed laxatives, iron, thyroid medication or investigation of a symptom is the mistake with actual consequences.

What does the research on KI17 actually say?

There is essentially nothing. We could not find any controlled human trial that tested KI17 (Shangqu) on its own, by acupressure or by any other method, for any condition. That is the honest headline.

Where KI17 appears in the research literature, it is one name inside a point prescription. Chinese-language acupuncture studies on functional constipation, irritable bowel and functional dyspepsia often use abdominal point groups that may include the Kidney abdominal line alongside points such as ST25, CV12 and ST36. When those trials report a result, it belongs to the whole protocol. No part of it can be assigned to KI17.

The wider picture is worth knowing. Abdominal massage — broad, whole-belly stroking rather than single-point pressure — has been tested in several small randomised trials for constipation, including in nursing-home residents and people with spinal cord injury, with some modest benefit reported. Those studies do not use acupressure points and cannot be used to support KI17. Acupressure research in general is dominated by small, short, unblinded trials in which participants know they are being touched, which inflates apparent benefit.

Compare this with PC6 on the wrist, where many controlled trials and systematic reviews support a real effect on nausea and vomiting. That is what decent point-specific evidence looks like. KI17 is nowhere near it.

What that means for you: anyone presenting KI17 as proven for digestion, fertility or menstrual pain is going beyond the evidence. The reasonable position is that gentle pressure here is low-risk on a healthy abdomen, may feel soothing, and has no demonstrated effect on any disease. If the evidence changes, this page should change with it.
