Foot Yangming,
the Stomach channel

The Stomach Channel at a Glance

In classical East Asian medicine, twelve principal channels were mapped over the body, and the stomach channel — the foot yangming channel — is their great workhorse. It carries the earth element in the five-phase framework, works in tandem with the spleen channel as the pair entrusted with turning food into strength, and wears the longest surface route of them all. On this site it is drawn with forty-five catalogued points, numbered ST1 through ST45 — a larger family than any other channel owns — beginning just beneath the eye and finishing at the outer corner of the second toenail.

This page is a whole-channel companion to the individual point pages. It follows the pathway the way classical sources drew it, introduces points whose roles tradition singled out, and gathers self-care ideas that stay strictly within the territory of light touch. It is educational material, not medical advice, and it teaches no diagnostic or therapeutic technique. Phrases such as “traditionally used for” report what historical practice reached for; they are not statements about proven outcomes.

Tracing the Course: From Beneath the Eye to the Second Toe

Classical drawings send the channel on a remarkable descent. Its first station, chengqi (ST1), sits directly below the pupil in the groove between eyeball and orbital rim, and three further points march straight down that same pupillary line: sibai (ST2) in the small depression of the infraorbital foramen, juliao (ST3) level with the lower edge of the nostril wing, and dicang (ST4) beside the corner of the mouth. From there the route wraps around the jaw — daying (ST5) ahead of the mandible’s angle where the facial artery beats, jiache (ST6) atop the taut bulge of the chewing muscle, xiaguan (ST7) in the hollow ahead of the ear that closes when the mouth opens — and climbs to touwei (ST8) at the temple corner, half a cun above the hairline. The neck segment follows the front edge of the sternocleidomastoid muscle: renying (ST9) beside the laryngeal prominence at the carotid pulse, shuitu (ST10) midway between its neighbours, and qishe (ST11) above the inner end of the collarbone.

Past the collarbones the channel settles into two famously regular columns. The chest run opens just above them, in the supraclavicular fossa at quepen (ST12), then drops along a line four cun lateral to the front midline, stepping down the rib spaces: qihu (ST13) at the collarbone’s lower edge, then kufang, wuyi, yingchuang, and ruzhong through the first, second, third, and fourth spaces — ruzhong (ST17) sitting at the nipple, kept chiefly as a landmark — with rugen (ST18) closing the set in the fifth space beneath the breast root. The belly run shifts to two cun lateral and marches twelve stations tall, from burong (ST19), six cun above the navel, down one cun at a time to qichong (ST30) just above the pubic crest; halfway along, tianshu (ST25) stands level with the centre of the navel itself.

At the groin the line swings outward onto the thigh, following the ridge between the hip bone’s forward point and the outer end of the kneecap. Biguan (ST31) leads, futu (ST32) waits six cun above the kneecap’s base on the quadriceps bulge, yinshi (ST33) three cun above the base, and liangqiu (ST34) two cun above it, before dubi (ST35) settles into the outer knee-eye hollow beside the patellar ligament. Down the shin the channel keeps one finger-breadth outside the shin bone’s front edge: zusanli (ST36) three cun below the kneecap, shangjuxu (ST37) six cun, tiaokou (ST38) eight cun, and xiajuxu (ST39) nine cun, with fenglong (ST40) a little higher on the fleshy slope to the side. The finale belongs to the ankle and foot: jiexi (ST41) in the midline crease between tendons, chongyang (ST42) on the pulsing high point of the instep, xiangu (ST43) behind the junction of the second and third metatarsals, neiting (ST44) at the web margin between the second and third toes, and lidui (ST45) at the outer corner of the second toenail.

Five Points Tradition Keeps Returning To

Tianshu (ST25) takes its name from two characters meaning celestial pivot, and the image suits a point that stands level with the navel, the body’s own centre mark. Classical ranking makes it the front-mu point of the large intestine — the spot tradition treats as closest to that organ’s sphere — and its recorded indications read accordingly: abdominal pain and distension, constipation, diarrhoea, and irregular menstruation. In traditional self-care it is imagined as a hinge for the middle of the body, consulted whenever the belly feels unsettled.

Zusanli (ST36) may be the single most storied address on the channel. Its three characters spell leg, three, and li — an old road-distance unit — recalling its position three cun below the knee. Classically it is the channel’s he-sea point, the place where flow gathers deep like a river meeting the sea, and older writings lean on it heavily whenever digestion flagged or strength ran low, recording it as a principal point for strengthening and health preservation. Modern writers discuss it more often than perhaps any other acupoint, a fame the evidence chapters of this site handle with deliberate caution.

Higher up the thigh, liangqiu (ST34) holds the channel’s xi-cleft post — the slot classical theory reserves for moments when a channel’s activity suddenly intensifies — and its recorded list pairs acute stomach upset with swollen, painful knees and breast pain. Further down, fenglong (ST40) serves as the luo-connecting point tying the stomach channel to its spleen partner; its characters sketch an abundant mound, a nod to the fleshy slope it occupies, and classical notes reach for it around copious phlegm, heaviness, and dizziness.

Neiting (ST44), the inner courtyard, closes the working shortlist. As the channel’s ying-spring point it belongs to the imagery of young water still close to its source, and the classical record puts toothache, sore swollen throat, acid regurgitation, and constipation on its docket. It sits within easy reach at the red-and-white skin line behind the web of the second and third toes. Every point in this shortlist keeps a full page of its own in the catalogue, carrying precise location steps, the complete recorded actions, and the dataset cautions summarised there.

Earth, Appetite, and the Sea of Grain

In the five-phase framework the stomach belongs to earth — the element of sowing, ripening, and feeding — and it shares that element, and a deep partnership, with the spleen channel climbing the leg’s inner side. Classical physiology casts the stomach as the sea of water and grain: the broad reservoir that receives food and drink and hands them onward for the spleen to sort and distribute. The two channels are treated as an exterior–interior pair, distinct lines bound so tightly together that old case discussions move between them almost without noticing.

The yangming label itself carries weight. Among the yang names assigned to channels on the body’s outer surfaces, yangming marked the brightest, most abundant aspect — commentators pictured sunlight falling full on a south-facing slope — and classical teaching matched that abundance to a channel unusually rich in points and unusually central to vitality. The traditional daily cycle likewise grants the stomach channel pride-of-place hours in the mid-morning, when, the story goes, the body stands readiest to receive nourishment.

These framings arrive here as cultural and historical context, attributed generally to pre-modern sources rather than quoted or verified. They explain why so much traditional advice about meals, routines, and strength orbits this channel, and why it anchors seasonal eating folklore across East Asia. They are not clinical claims, and this page makes none: digestion is studied by modern medicine with its own instruments, and nothing here substitutes for that.

Everyday Complaints and Gentle Practice

People usually arrive at this channel through ordinary moments: a belt loosened after a heavy meal, a jaw clenched through a stressful week, legs gone heavy after a long day on their feet. Traditional framing reads each of these as territory along the stomach line, and gentle self-applied pressure grew up as a companion habit to such days. What such practice can honestly offer is modest: a few unhurried minutes, longer exhalations, attention turned back to the body from the screen. Where modern research touches self-applied pressure at all, reviews suggest effects are modest and context-dependent, and the same reviews concede that study quality varies widely across applications.

The home repertoire stays simple. After a large meal, some people rest a flat palm just beside the navel and circle it slowly, letting warmth and light contact do the work. Seated with a knee bent, a fingertip can settle at zusanli (ST36) below the outer kneecap hollow; pressure rises only to the edge of comfort, stays for a handful of slow breaths, and eases off gradually. At day’s end the neiting (ST44) webspace welcomes a brief thumb roll, and the masseter bulge at jiache (ST6) softens under slow fingertip circles while the teeth rest apart. None of this asks for strength; the whole grammar of the practice is patience.

Boundaries matter more here than on most channels. The eye-region points are for looking at, not pressing — the catalogue records serious cautions around them — and the neck stations sit directly over major arteries, so the throat line belongs entirely with professionals. Across the chest and breast area, a light flat palm is the ceiling; deeper work adds nothing worth having. Avoid broken or irritated skin, stop at once on any sharp, electric, or radiating feeling, and if you are pregnant, manage a health condition, or take medication that affects bleeding, ask a qualified practitioner before adding self-pressure to your routine.

Who This Page Helps

Curious newcomers meet the meridian system best through a channel with obvious geography, and few routes are easier to walk than this one: start beneath your own eye and count your way down to your toes. Readers already visiting individual stomach pages will find here the connective tissue — why the points queue where they do, which carry classical titles, how the line relates to the spleen channel beside it. Students of East Asian medicine’s history, and anyone assembling a seasonal wellness routine, will recognise familiar ground stated plainly.

Some readers should hold this page loosely. Anyone hoping for treatment promises will not find them; none are made. People with acute abdominal pain, a recent injury, or symptoms that frighten them belong with a clinician first and a wellness page second, if at all. And if even light touch somewhere along the line feels wrong, that feedback outranks any routine — skip the spot, and if the feeling persists, mention it at your next appointment.

When Symptoms Need Professional Eyes

Certain signs end the self-care conversation before it starts. Severe or lasting abdominal pain, vomiting blood or black stools, trouble swallowing, unexplained weight loss, chest pain, breathlessness, high fever, or new numbness or weakness all call for prompt medical assessment. A toothache belongs with a dentist, a hot swollen knee with a clinician, and a jaw that locks or clicks painfully with whoever examines joints. Pressure practices are for comfortable days, not for triage.

Between emergencies and everyday comfort stretches the long middle country of reflux, irregular digestion, recurring headaches, and tired legs — territory where licensed practitioners, including registered acupuncturists and traditional medicine clinicians, can offer channel-informed perspectives alongside conventional care. Expect coordination with your regular doctors rather than replacement of them. When you want the fine print for any single stop on the line, the catalogue pages for ST1 through ST45 carry exact locations, the complete recorded actions, and every dataset caution this overview deliberately left to them.
