ST-27 (Da Ju) Great Gigantic

What does ST-27 Da Ju do?

ST-27 benefits the Kidneys and firms essence, and it regulates qi and promotes urination — and it is the point where the Stomach abdominal line stops being digestive and becomes urogenital.

• Benefits the Kidneys and firms essence — a Kidney action, on a Stomach point
• Regulates qi and promotes urination — the lower-burner action

The change across the navel is the finding of this page. Above the umbilicus the Stomach 2-cun line is digestive throughout — our ST-19, ST-20 and ST-23 records carry gastric pain, distension and vomiting. Below it the same line turns to the lower burner: ST-27 benefits the Kidneys and firms essence, which is Kidney-channel language on a Stomach point. The channel has not changed; the region beneath it has — the lower abdomen holds the bladder, the reproductive organs and the intestines, and the points over them take their actions accordingly. It is the anatomy speaking through the classical action, and it is stated as a correspondence rather than a mechanism.

“Firms essence” is the classical account of its reproductive indications. Jing, essence, is the Kidney’s stored reproductive vitality in the tradition, and “firming” it is the treatment principle for involuntary loss — which is exactly what the seminal-emission and premature-ejaculation indications describe.

On the name. “Da Ju” means Great Gigantic, sometimes rendered The Great — da great, ju huge. The readings offered relate it to the prominence of the lower abdomen. It is a name of emphasis rather than description, and our data holds it as given.

What is ST-27 Da Ju used for?

ST-27 is used for lower abdominal distension, difficult urination, hernia, seminal emission and premature ejaculation. Our own indication record is reproduced here in full.

• Lower abdominal distension
• Dysuria (difficult or painful urination)
• Hernia
• Seminal emission
• Premature ejaculation

Entirely lower-burner — urinary, genital and hernia — and not a digestive entry among them. That is the sharp contrast with the run above the navel, and it confirms the action: the point sits over the bladder and the reproductive structures, and its indications are their complaints. Our neighbouring ST-26 Wai Ling record carries hernia and dysmenorrhoea; the lower Stomach points share this urogenital and hernia territory.

An honest note, and several entries need one. DIFFICULTY PASSING URINE, AND ESPECIALLY AN INABILITY TO PASS URINE, REQUIRES URGENT MEDICAL ASSESSMENT — a distended, painful bladder that cannot empty is an emergency. A HERNIA THAT BECOMES PAINFUL, TENSE OR IRREDUCIBLE IS A SURGICAL EMERGENCY, and any hernia warrants assessment. Seminal emission and premature ejaculation deserve proper assessment where they are troubling — both have treatable causes, some physical, and are not well managed by a classical indication alone. New or persistent lower abdominal distension requires assessment. This record documents classical use only, and nothing here should delay any of that.

How it is combined. With ST-26 Wai Ling above and ST-28 Shui Dao below on the same line. With REN-05 Shi Men and REN-04 Guan Yuan on the midline — REN-04 the classical point for the essence and the lower burner. With KI-12 and KI-13 and SP-06 San Yin Jiao for the reproductive indications. All held here.

Where is ST-27 Da Ju located?

ST-27 is on the lower abdomen, two cun out from the midline and two cun below the navel, level with REN-05 Shi Men.

• 2 cun lateral to the midline, 2 cun below the umbilicus
• Level with REN-05 Shi Men on the midline
• ST-26 Wai Ling lies one cun above at 1 cun below the navel; ST-28 Shui Dao one cun below at 3 cun

The Stomach abdominal line pairs one-to-one with the Conception Vessel below the navel just as it does above. ST-26/REN-07, ST-27/REN-05, ST-28/REN-04 — each level with a named Ren point, continuing the pattern our ST-19, ST-23 and ST-24 records set out for the upper line. The navel is the pivot: above it the points are digestive, below it urogenital, and the pairing with the midline vessel holds throughout.

A practical note for the lower abdomen. The bladder rises out of the pelvis when it is full, and a full bladder brings its wall closer to the surface at points this low. Our records do not hold a specific caution for ST-27, and none is asserted, but the state of the bladder changes what lies beneath a lower-abdominal point — which is a general fact of the region worth knowing before treatment here.

On the name. “Da Ju” — Great Gigantic, a name of emphasis relating to the lower abdomen.

• A Manual of Acupuncture (p. 150): On the lower abdomen, 2 cun lateral to the midline and 2 cun inferior to the umbilicus, level with Shimen REN-5.

How is ST-27 Da Ju needled?

Our own record states perpendicular insertion of 0.7–1.2 inches, with moxibustion applicable — a deeper recorded range than the upper-abdominal points, reflecting the thicker lower abdominal wall. What follows is a neutral record of what the reference literature documents. It is not instruction, and this page does not teach technique.

• Angle and depth as recorded: perpendicular, 0.7–1.2 inches — matching ST-26 beside it, and deeper than the 0.5–0.8 inch at ST-19 high on the run. The lower abdominal wall is thicker and there is no liver or costal margin beneath it, so the recorded depths lengthen.
• Moxibustion: recorded as applicable.
• Regional anatomy: rectus abdominis and its sheath overlie the peritoneal cavity; the small intestine lies deep, with the bladder below in the pelvis — rising to this level when full — and the reproductive organs beyond; there is no bone beneath the abdominal wall.

Hazard, stated proportionately. The peritoneal cavity lies directly beneath, which is why the depth is bounded even though the wall is thick. The one region-specific consideration is the bladder: a full bladder brings its wall nearer the surface at points this low, which our record does not warn about specifically but which the anatomy makes worth knowing. No organ-injury caution attaches to ST-27 — only four points in the library carry one, counted by query.

What is not claimed. No study measuring a safe depth at ST-27 could be located, and none is borrowed. Neither measured-depth study this library uses reaches the abdomen. No case report naming ST-27 was located.

Is there research on ST-27, and what should a reader know?

No trial isolates ST-27. Where the point appears it is one component of a urinary or reproductive protocol, and a study that includes a point in a protocol is not evidence about that point.

What this page can state with confidence. ST-27 is the point where the Stomach abdominal line crosses from digestive to urogenital: above the navel its neighbours treat the stomach, and here, two cun below it, the recorded action benefits the Kidneys and firms essence — Kidney-channel language on a Stomach point, because the region beneath has changed from stomach to bladder and reproductive organs. Its indications are entirely lower-burner. It sits level with REN-05, continuing the one-to-one Conception Vessel pairing below the navel. And its recorded depth is deeper than the upper points, tracking the thicker wall.

The warnings are the operative content. Inability to pass urine, and a painful or irreducible hernia, are emergencies, and reproductive symptoms deserve proper assessment.

A note on searching for it. “ST 27”, “S 27” and “Daju” searches return protocol trials and a large volume of unrelated material — “Daju” matches personal names and ordinary vocabulary. Any claim attached to this point should be checked against what a study actually used.
