The 'Beam Gate' of the stomach. Liangmen (ST-21) is a focused local point on the upper abdomen that harmonises the Middle Burner, clears accumulations and restores the smooth downward flow of Stomach Qi — the quiet gatekeeper of digestion when things are stuck or rebellious.
Name & story
The name 梁门 Liangmen means 'Beam Gate'. A 'liang' (梁) is a beam or girder — something solid and obstructing — and 'men' (门) is a gate, a place where things pass through. The image is of a heavy beam blocking a doorway: Qi and food accumulate and cannot move on. The point's job is to lift that beam and open the gate again. There is also a classical layer: the character 'liang' refers to one of the 'five accumulations' described in the Classic of Difficulties, a palpable mass sitting in the epigastrium below the Heart. Liangmen ST-21 was singled out in various classics specifically for epigastric pain and Qi accumulation in the chest and costal region — suggesting it was always understood as a point that breaks up what has settled and shouldn't.
Point family & character
Liangmen (ST-21) belongs to the Stomach Meridian (ST). It is a local abdominal point without a special classical category (it is not a Yuan Source, Xi Cleft or He-Sea point), but its position — level with Zhongwan REN-12, the Front-Mu point of the Stomach — gives it strong practical authority over the Middle Jiao.
Five-element dynamics
The Stomach Meridian (ST) belongs to the Earth element, and the Earth element governs digestion, transformation and the smooth downward movement of food and Qi through the body. When that movement is disrupted — when food accumulates, Qi rebels upward and the Middle Jiao becomes stuck — symptoms like pain, vomiting, hiccups and bloating arise. Liangmen ST-21 addresses the Earth element right at the centre of its territory: the epigastrium, the body's processing hub. By harmonising the Middle Jiao and directing rebellious Stomach Qi back downward, it restores the Earth element's fundamental rhythm of receiving, ripening and letting go.
Location
On the abdomen, 4 Cun above the navel and 2 Cun to the side of the midline, level with Zhongwan REN-12. The 2 Cun line sits roughly halfway between the midline and the palpable outer edge of the rectus abdominis muscle. In patients with a narrow ribcage, the point may fall on or near the costal margin.
Anatomy & fascia
The point lies on the abdomen, over the rectus abdominis muscle.
Needling
The needle is inserted perpendicularly (straight in). In thin or lean patients, care is needed not to go too deep, as deep needling may penetrate the peritoneal cavity.
Safe depth
Safe depth — 1–1.5 Cun, depending on the patient's build. Use caution in thin patients.
Moxa, cupping & Tui Na
Moxa is well suited to this point, particularly when the presentation involves Cold in the Middle Jiao — cold-type epigastric pain, poor appetite from weakness or Cold accumulation. Gentle massage or acupressure over the point can help relieve mild stomach discomfort at home.
Functions
Harmonises the Middle Jiao and regulates the Stomach. Descends rebellious Stomach Qi and rebellious Lung Qi. Transforms food accumulation and stagnation. Relieves epigastric pain and disperses masses in the epigastrium.
Indications
Epigastric pain; poor appetite; abdominal distention and fullness; borborygmus (rumbling in the belly); diarrhoea (including chronic or 'slippery' diarrhoea from Qi collapse); vomiting; vomiting blood; spitting blood; hiccup; difficult ingestion. Hardness and pain in the lateral costal region. Shortness of breath, wheezing and difficult breathing with raised shoulders — reflecting the point's action on descending both Stomach and Lung Qi.
Point combinations
With Chengman ST-20 and Zhongwan REN-12 — for hardness and pain in the lateral costal region (from the Thousand Ducat Formulas). With Chengman ST-20, Zhongfu LU-1, Kunlun BL-60, Yuji LU-10 and Zhourong SP-20 — for difficult ingestion (from Supplementing Life).
Clinical spotlight
One of the most telling details in the classical literature is the link between Liangmen ST-21 and the concept of 'five accumulations' from the Classic of Difficulties. The 'liang' accumulation — a palpable, obstructing mass below the Heart in the epigastrium — points to the point's specialty: not just mild sluggishness, but real stubborn stagnation in the Middle. Equally striking is its dual action on both Stomach and Lung: wheezing and breathing difficulty with raised shoulders appear in its indication list, reminding us that rebellious Qi in the Stomach can press upward and disturb the Lung's descending function. Clearing the gate below can sometimes open the chest above.
The golden tip
For mild stomach fullness, epigastric discomfort or a sensation of heaviness after eating, find Liangmen ST-21 about four finger-widths above the navel, roughly halfway between the midline and the outer edge of the abdominal muscles on either side. Gentle circular massage with the fingertips for 1–2 minutes can help ease the feeling of accumulation and encourage digestion to move again. A warm compress or heat pack over the area is soothing when the discomfort feels cold or cramping in nature.
