REN-11 (Jian Li) Interior Strengthening

What does REN-11 Jian Li do?

REN-11 has a single recorded action — it harmonises the middle burner and regulates qi — and our record holds no special-point classification for it at all. That absence is worth stating plainly rather than papering over: REN-11 is not a Front-Mu point, not a Hui-Meeting point, and not a meeting point of channels. It is a midline abdominal point defined by its position between two that are.

• Harmonises the middle burner and regulates qi — the whole of the recorded action

Its position is its meaning. REN-11 sits three cun above the navel, between REN-10 Xia Wan (two cun above, “Lower Venter”) and REN-12 Zhong Wan (four cun above, “Middle Venter”). REN-12 is the Front-Mu point of the Stomach and the Hui-Meeting point of the Fu organs — one of the most heavily classified points on the body. REN-11 lies immediately below it and shares its territory without its titles.

Why a reference should say that clearly. A reader comparing points on this stretch of midline will find REN-12 carrying two major classifications, REN-13 and REN-10 carrying channel meetings, and REN-11 carrying none. That is a real difference in standing, and inventing a classification to make the page look fuller would misrepresent the tradition.

What is REN-11 Jian Li used for?

REN-11 is used for stomach and digestive complaints — pain, vomiting, distension, rumbling, poor appetite — and for oedema. Our own indication record is reproduced here in full.

• Stomach ache
• Vomiting
• Abdominal distension
• Rumbling in the abdomen (borborygmus)
• Oedema
• Loss of appetite

The list is entirely middle-burner, which is consistent with a point that carries one action and no classification. There is no spirit indication, no gynaecological indication and no distal reach — unusual restraint for an abdominal point, and a sign the record has not accumulated the general indications of its neighbours.

How it is combined. With REN-12 Zhong Wan immediately above it, the Front-Mu of the Stomach, which is the principal point for this territory. With ST-36 Zu San Li, the Lower He-Sea point of the Stomach, as the standard distal partner. With BL-21 Wei Shu, the Stomach’s Back-Shu point, in the classical front-and-back pairing. With ST-25 Tian Shu beside the navel for the intestines. All held here.

Where is REN-11 Jian Li located?

REN-11 is on the midline of the abdomen, three cun above the navel and five cun below the sternocostal angle. Our record gives both measurements, which is useful because the two reference points fail in different circumstances.

• 3 cun above the umbilicus on the anterior midline
• 5 cun below the sternocostal angle — the meeting of the rib margins
• The umbilicus-to-sternocostal-angle distance is taken as 8 cun in proportional measurement, and the two figures given here add to exactly that

The two measurements check each other. Three cun up from the navel and five cun down from the rib angle should land on the same spot; if they do not, the proportional division has gone wrong. That internal consistency is the practical value of recording both, and it is why this record keeps them rather than reducing to one.

The Ren Mai abdominal points are counted, not felt. REN-09, REN-10, REN-11, REN-12 and REN-13 lie at one-cun intervals up the midline with no landmark between them. All five are held here, and a miscount substitutes one for another.

On the name. “Jian Li” is rendered Interior Strengthening or Strengthening the Interior — a functional name that matches its single recorded action, unusually for a Ren Mai point whose neighbours are named for their position (Upper, Middle and Lower Venter).

• A Manual of Acupuncture (p. 510): On the midline of the abdomen, 3 cun above the umbilicus and 5 cun below the sternocostal angle.
• Chinese Acupuncture and Moxibustion (p. 238): On the anterior midline, 3 cun above the umbilicus.

How is REN-11 Jian Li needled?

The standard texts record perpendicular insertion to roughly 0.5–1.2 inches, with moxibustion applicable — and our own record carries an explicit pregnancy caution covering this point. What follows is a neutral record of what the reference literature documents, not instruction for a reader.

• Angle and depth as recorded: perpendicular, 0.5–1.2 inches.
• Moxibustion: recorded as applicable.
• Pregnancy, as recorded verbatim in our own data: great care should be taken with the points from Qu Gu REN-02 to Shang Wan REN-13 in pregnancy. REN-11 sits within that range, in its upper half.
• Regional anatomy: the linea alba lies beneath the point on the midline, with the stomach and transverse colon behind the abdominal wall; the depth of the wall varies considerably with body habitus.

Hazard, stated proportionately. Abdominal points carry a depth consideration rather than a fixed hazard, because how much tissue lies between skin and viscera depends on the person. An ultrasound study of the abdominal wall measured REN-12, one cun above — 25.3 ± 10.2 mm, with the liver visible in 62.7% of subjects. Several records in this library cite it, including REN-10, REN-13, ST-21 and ST-30, and every one of them attributes the figure to REN-12 as the point actually measured. It belongs to REN-12, not to REN-11, and it is not borrowed here. No study measuring a safe depth at REN-11 could be located, and no case report naming this point was located.

Is there research on REN-11, and what should a reader know?

No trial isolates REN-11. Where the point appears it is one component of an abdominal protocol, usually alongside REN-12 and ST-36, and a study that includes a point in a protocol is not evidence about that point.

The honest summary is that REN-11 is a minor point on a major stretch of channel. It carries one action, no classification, and a short indication list confined to the middle burner. Its neighbour REN-12 carries two of the most significant classifications in the system and most of the research attention. A reader looking for the principal point of this territory should be reading REN-12; REN-11 is where a practitioner goes when the treatment calls for that territory without REN-12’s weight.

Saying so is more useful than padding. This library has taken the same approach on other minor points — Song Jie among the herbs, Pi Gen and Zhong Quan among the extra points — where a short accurate page beats a long one assembled from a neighbour’s material. What a reader needs from this page is the position, the single action, the pregnancy caution, and the fact that the classification is genuinely absent.

A note on searching for it. “CV 11”, “REN 11” and “Jianli” searches return protocol trials and, as repeatedly found throughout this library, unrelated material matched on the code or on a surname — “Jianli” in particular is a common personal name. Any claim attached to this point should be checked against what a study actually used.
