What is KI20?

KI20 (Futonggu) is a Kidney-channel point on the upper abdomen, about a finger-width to the side of the midline, well above the navel.

Its pinyin name, Futonggu, is usually translated as "Abdomen Connecting Valley" or "Open Valley". It is one of a vertical row of Kidney points that climb the belly on each side of the midline, from the pubic bone up to the ribs. KI20 sits near the top of that row, just below KI21.

In classical Chinese medicine the point is filed under digestion. Old texts link it to pain and fullness below the ribs, vomiting, poor appetite and food that "sits" undigested. Some texts also mention cough and a tight, fluttery feeling in the chest. Those are traditional categories, not diagnoses in the modern sense.

Two things are worth saying once, up front. Being named in every classical point list tells you KI20 is old and widely taught; it does not tell you the point does anything measurable. Long tradition is also not a safety record. Whether pressure here is sensible for you depends on your own body and what is going on in your abdomen today.

The honest verdict on evidence: there is essentially no human research on KI20 by itself. Acupressure research as a whole is dominated by a handful of famous points, and this is not one of them. What research exists on acupressure generally tends to be small, short and hard to blind, because the person pressing and the person being pressed both know it is happening.

None of that makes KI20 useless as a self-care habit. A few minutes of slow, warm pressure on a soft belly, with slow breathing, is a pleasant and low-risk thing for most healthy people to do. Just hold it as comfort and routine rather than treatment, and keep real abdominal symptoms in front of a doctor.

Where is KI20 and how do you find it?

KI20 sits on the upper abdomen, roughly five thumb-widths above the navel and only about half a thumb-width out from the midline.

• Lie down first. Rest on your back with your knees bent and feet flat. This softens the belly wall and makes the midline and the lower edge of the breastbone much easier to feel.
• Find your two anchors. Put one fingertip in your navel and the other on the bony lower tip of your breastbone (the sternum). Everything on this point row is measured between those two landmarks.
• Divide the gap. Traditionally that navel-to-breastbone distance is counted as eight equal parts, or eight cun. KI20 lies five parts up from the navel, which is about two-thirds of the way toward the breastbone.
• Convert it roughly. On most adults five parts works out near 12 to 13 cm, or about five of your own thumb-widths stacked above the navel. Use your own thumb, not an average, because the measure is meant to scale to your body.
• Step sideways a little. From that midline spot, move out to one side by about half a thumb-width, roughly 1 cm. KI20 is a close-in point, not out on the flank.
• Check what is under your finger. You should feel soft abdominal wall, not the hard breastbone and not the firm ridge of a rib. If you are on bone, you have gone too high or too far out.

There is a matching KI20 on each side of the midline. Many people notice the area feels slightly tender or doughy compared with the skin around it, but tenderness is not proof you have found it.

If you are unsure, stay conservative. What is agreed across sources is the general zone: upper abdomen, high above the navel, close to the midline. Press gently in that zone rather than hunting for a precise spot. This page describes finger pressure only, never needles.

How do you apply pressure to KI20?

1. Pick your moment. Work on a reasonably empty stomach, ideally an hour or more after a meal. Pressing a full belly is uncomfortable and can make reflux worse.
2. Get comfortable. Lie on your back with knees bent, or sit back in a chair and let your abdomen relax. Warm your hands first; cold fingertips make the belly tense up.
3. Use a flat fingertip. Place the soft pad of your index or middle finger on the point. Keep nails short and off the skin. A thumb is fine if it feels steadier.
4. Sink in slowly. Press straight down as you breathe out, over about three seconds. The abdomen is soft tissue, so go in gently; this is not a place to lean your body weight.
5. Judge the pressure. Aim for a firm, dull, slightly tender feeling, roughly three or four out of ten. Sharp pain, a pulsing lump under your finger, or nausea means stop immediately.
6. Hold and breathe. Keep steady pressure for 30 to 60 seconds, or make small slow circles. Let your belly rise against your finger as you breathe in.
7. Do both sides. Release slowly, then repeat on the other side. One to three rounds per side is plenty.
8. Repeat sensibly. Once or twice a day is reasonable. Give the area a rest if the skin stays red or the muscle feels sore the next day.

Stop the session and leave the area alone if you feel a sharp or deepening pain, if the spot throbs, if you feel faint, or if pressing makes you want to vomit. Those are signals to put your hand down, not to press harder.

Everything here is self-applied finger pressure. Nothing on this page involves needles, skin-breaking, burning herbs or suction cups, and none of those belong in home self-care.

What is KI20 traditionally used for?

• Upper abdominal pain and fullness. This is the headline classical use: a bloated, blocked, heavy feeling below the ribs. No controlled human trial has tested KI20 for this, so the claim rests on tradition and on how the pressure feels at the time.
• Nausea and vomiting. Old texts list vomiting among its indications. The real evidence for acupressure and nausea sits with PC6 on the forearm, where repeated controlled trials show a modest genuine benefit, especially after surgery and in pregnancy. That evidence belongs to PC6 and does not transfer to KI20.
• Poor appetite and sluggish digestion. Described traditionally as food failing to move on. Human evidence for acupressure improving appetite or digestion at this point is absent; what exists on abdominal massage generally is small, unblinded and short-term.
• Cough and chest tightness. Some classical sources add a tight chest and cough, reflecting the point's position just under the ribs. There is no modern human research supporting KI20 for respiratory symptoms.
• Palpitations and anxious restlessness. A few texts mention a fluttery, uneasy chest. Slow abdominal pressure with long exhalations does tend to calm people, but that is probably the breathing and the touch rather than anything specific to KI20.
• General belly comfort. Many people use it simply as a place to rest a warm hand during period cramps or a stressful day. That is a reasonable comfort habit and makes no medical claim at all.

Across the whole list, the pattern is the same: a long and consistent traditional record, and almost no point-specific human trials. Acupressure studies in general are usually small, cannot blind the participant, and measure outcomes over days rather than months.

Treat KI20 as a comfort measure layered on top of proper care, never as a replacement for it. Persistent upper abdominal pain, repeated vomiting or unexplained weight loss need a medical assessment, not more pressing.

Are there tips for using KI20 effectively?

• Measure with your own thumb. Cun measurements scale to the body they are on. Use your own thumb-width for the five-up and half-out steps rather than a ruler or someone else's numbers.
• Soften the belly first. Knees bent, shoulders down, one slow breath out before you press. A braced abdominal wall hides the point and makes everything feel like muscle.
• Press on the exhale. Sinking in as you breathe out is more comfortable and keeps you from pushing against a rising diaphragm.
• Warm the area. A warm palm or a covered hot water bottle rested on the upper belly for a minute beforehand makes the tissue more comfortable to work on. Keep anything hot off bare skin.
• Work both sides evenly. KI20 is paired. Giving each side the same time keeps the session balanced and stops you leaning into one spot too long.
• Less force, more time. Gentle sustained contact for a minute is better tolerated on the abdomen than hard poking. Depth is not the goal here.
• Keep a short log. Note the date, how long you pressed and how you felt an hour later. Over a few weeks that tells you far more than one dramatic session.
• Pair it with the basics. Smaller meals, less late eating, and a short walk after dinner have real evidence behind them for upper-gut comfort. Acupressure sits alongside those, not instead.
• Stop on any sharp signal. Sharp pain, a pulsing sensation, dizziness or rising nausea all mean take your hand away and leave the area alone.

One practical note on expectations: if a habit has done nothing noticeable after two or three weeks of honest trying, it is reasonable to let it go. That is a sensible decision, not a failure.

What do people get wrong with KI20?

• Expecting a cure. The biggest error. KI20 is a comfort measure with no proven effect on any disease, and no acupressure point cures indigestion, reflux or anything else.
• Landing on bone. Pressing the hard lower tip of the breastbone or the rib edge instead of the soft abdominal wall just below and to the side. Bone means you are too high or too far out.
• Going too far sideways. The Kidney abdominal points sit close in, about half a thumb-width from the midline. Drifting two thumb-widths out puts you on a different channel entirely.
• Mixing it up with neighbours. KI20 is five parts above the navel; KI21 is one part higher and KI19 one part lower. If you are not sure, press gently in the general zone rather than claiming precision you do not have.
• Pressing straight after a meal. A full stomach makes the area tender and can push acid upward. Wait an hour or more.
• Using force. Digging a knuckle or a hard massage tool into the upper abdomen can bruise and is genuinely unsafe over organs. Finger pad pressure only.
• Pressing through real pain. Treating a sharp, worsening or one-sided abdominal pain as a blockage to be released. Severe belly pain is a medical problem, and pressing it wastes time.
• Ignoring a pulse under the finger. A strong throbbing in the upper abdomen should never be massaged. Lift your hand off and get it checked.
• Doing it on broken skin or a scar. Rashes, open wounds and fresh surgical scars on the belly are all reasons to skip the point for now.
• Dropping real treatment. Stopping prescribed reflux or stomach medication in favour of pressing a point is the most harmful mistake on this list.

What does the research on KI20 actually say?

There is no useful human research on KI20 specifically. A search of the acupressure and acupuncture literature turns up no controlled trial, no comparison study and no published case series that tests this point on its own for digestive symptoms or anything else. That is the honest answer, and inventing a study to fill the gap would be worse than saying so.

KI20 does appear inside multi-point acupuncture protocols in some practice reports, mostly for abdominal complaints. Those designs cannot tell you what any single point contributed, because several points were stimulated at once, usually with needles rather than fingers. Reporting what a trial needled is fine; it simply does not translate into a self-pressure instruction.

It is worth seeing what adequate evidence actually looks like, for contrast. PC6 on the inner forearm has been tested repeatedly in randomised controlled trials against sham pressure for nausea and vomiting, including after surgery, during chemotherapy and in pregnancy. The effect is modest but real and reasonably consistent. That is the clearest case in the whole acupressure literature, and KI20 is nowhere near it.

The broader limits matter too. Acupressure studies are usually small, run for days or weeks rather than months, and cannot blind the participant, who always knows a thumb is on their skin. Outcomes are commonly self-reported comfort scores, which drift upward with attention and expectation alone. Even where results look positive, these designs tend to overstate the effect.

What that means for you is simple. Nothing published supports a claim that KI20 treats a condition. If you find it soothing, it is a low-cost comfort habit for most healthy people. Treat any real or lasting abdominal symptom as a reason to be examined by a clinician, and judge future claims about this point by whether anyone has actually tested it.
