REN-14 (Ju Que) Great Tower Gate

What does REN-14 Ju Que do?

Ju Que REN-14 is the Front-Mu point of the Heart — the place on the front of the body where the Heart's qi is said to gather — and its defining recorded work is to regulate the Heart and relieve pain in the cardiac region. Sacred Lotus sources & references record that classification directly, and it is the only Front-Mu point of the Heart in the whole repertoire. The point sits on the front midline just below the tip of the breastbone, at the junction of chest and abdomen, and its recorded actions divide neatly along that seam: upward into the chest and the Heart, downward into the stomach.

• Regulates the Heart and alleviates pain — the primary recorded action and the Front-Mu action proper. This is the point on the front of the body used where the complaint is felt at the heart: pain and oppression behind the breastbone, palpitations, a gripping or knotted sensation in the cardiac region.
• Transforms phlegm and calms the spirit — the action behind REN-14's classical use in mental-emotional disturbance and epilepsy. In classical theory, phlegm that misted the orifices of the Heart was the standard explanation for disordered mind and consciousness, and the Heart's Front-Mu point is where that pattern is addressed from the front.
• Descends Lung qi and unbinds the chest — for a tight, oppressed, congested chest, for cough and for breathlessness. REN-14 lies at the bottom of the chest, and the tradition uses it where the chest as a whole will not open.
• Harmonises the Stomach and descends rebellion — for nausea, vomiting, acid regurgitation, belching, hiccup and difficulty swallowing. The point sits directly over the epigastrium, and much of its everyday use in practice is digestive rather than cardiac.
• Serves as the Heart's diagnostic point — as with all Front-Mu points, tenderness or a change in the tissue at REN-14 is read as an "alarm" referring to the organ it names, and the point is palpated as well as needled. That diagnostic role is the reason the Front-Mu points are sometimes called alarm points.

What is REN-14 Ju Que used for?

Ju Que REN-14 is used for pain in the cardiac region and the chest, for nausea, acid reflux and vomiting, and — most distinctively among the Conception Vessel points — for disturbances of the spirit including epilepsy and mental disorder. The indications below are those carried in Sacred Lotus sources & references together with those set out in the standard reference literature. They describe traditional use, not proven treatment, and this point carries the depth facts set out under needling.

• Pain, fullness and oppression of the chest
• Palpitations and a racing or fluttering heart
• Anxiety and agitation
• Mental disorders and disturbed spirit
• Epilepsy and convulsive disorders
• Nausea
• Vomiting
• Acid regurgitation and heartburn
• Belching and hiccup

Where is REN-14 Ju Que, and how is it used in practice?

Ju Que lies on the front midline of the upper abdomen, six cun above the navel — which our records also give as two cun below the point where the ribs meet at the bottom of the breastbone. Sacred Lotus sources & references give it in both terms, and the second is the one that makes the anatomy plain: REN-14 sits just below the xiphoid process, in the soft hollow beneath the tip of the sternum, at the exact seam between chest and abdomen. It is the point immediately above Zhong Wan REN-12 and immediately below Jiu Wei REN-15 on the same line.

In practice REN-14 is the front-of-body point for the Heart, and it is used in two quite different ways. Where the complaint is cardiac or emotional — chest oppression, palpitations, anxiety, a spirit that will not settle — it is used as the Heart's Front-Mu point, typically paired with its Back-Shu counterpart. Where the complaint is digestive, it is used as a local epigastric point alongside its neighbours on the same line. It is very commonly treated with moxibustion: a data-mining analysis of the earliest ancient acupuncture and moxibustion prescriptions for epigastric pain found that on the trunk, moxibustion was generally the method used at Wei Shu BL-21, Pi Shu BL-20, Ge Shu BL-17, Zhong Wan REN-12, Ju Que REN-14 and Qi Hai REN-06 (Zhongguo Zhen Jiu 2025;45(2):253–261, PMID 39943771). That is a genuinely point-specific historical finding, and it matches how the point is treated today.

Which points is REN-14 combined with?

• With Xin Shu BL-15 — the Shu-Mu combination. This is the definitive pairing on the page. BL-15, beside the fifth thoracic vertebra on the upper back, is the Back-Shu point of the Heart, confirmed by query in Sacred Lotus sources & references, and it is written up in this library alongside this record. Front-Mu with Back-Shu — the front and the back of one organ, needled together — is the oldest structured pairing in the medicine, and this is its Heart instance. Data-mining of ancient prescriptions for epigastric pain identifies the Back-Shu-with-Front-Mu combination as one of the four recurring structures of the classical repertoire (PMID 39943771).
• With Nei Guan P-06 — the Connecting point of the Pericardium at the wrist and the standard distal point for the chest, the heart, nausea and palpitations. Local point on the midline with distal point on the arm is the usual structure, and P-06 is the partner REN-14 is most often given. Our library codes the Pericardium channel P-06, not with the other common abbreviation.
• With Zhong Wan REN-12 — the Front-Mu point of the Stomach and the Hui-Meeting point of the fu organs, two cun below on the same line, wherever the digestive half of REN-14's range is the focus.
• With Shan Zhong REN-17 — the Hui-Meeting point of qi and the Front-Mu of the Pericardium, higher on the breastbone, where the chest rather than the epigastrium is the seat of the oppression.
• With Shen Men HT-07 and Bai Hui DU-20 — for palpitations, anxiety and disturbed spirit, adding the Heart's own Source point at the wrist and the meeting point at the crown.
• With Feng Long ST-40 — the Connecting point of the Stomach channel and the tradition's principal phlegm point, added wherever the pattern is phlegm misting the Heart: mental confusion, epilepsy, a heavy muddled head.
• With Jiu Wei REN-15 — its immediate neighbour one cun below, the Connecting point of the Conception Vessel. The two share almost all of their territory, and our REN-15 record notes from its own side that where an established Front-Mu classification is wanted for a Heart complaint, REN-14 is the point chosen.

Where does REN-14 sit among the Front-Mu points?

The Front-Mu or "alarm" points are a set of twelve on the front of the trunk, one for each organ, where that organ's qi is said to gather and where tenderness signals its involvement. Sacred Lotus sources & references hold the complete set:

• Zhong Fu LU-01 — Lungs
• Shan Zhong REN-17 — Pericardium
• Ju Que REN-14 — Heart. This page.
• Qi Men LIV-14 — Liver
• Ri Yue GB-24 — Gallbladder
• Zhang Men LIV-13 — Spleen
• Zhong Wan REN-12 — Stomach
• Shi Men REN-05 — San Jiao
• Jing Men GB-25 — Kidneys
• Tian Shu ST-25 — Large Intestine
• Guan Yuan REN-04 — Small Intestine
• Zhong Ji REN-03 — Bladder

Two things are worth noticing in that list, and both are visible only when it is read whole. First, the Front-Mu points are not on their own organ's channel — the Heart's is on the Conception Vessel, the Spleen's is on the Liver channel, the Kidneys' is on the Gallbladder channel. They are assigned by where an organ can be reached from the front, not by which line runs over the spot. Second, six of the twelve are on the Conception Vessel, running down the midline in roughly anatomical order from the Heart at REN-14 to the Bladder at REN-03. Each pairs with its organ's Back-Shu point on the back: REN-14's counterpart is Xin Shu BL-15, and that pair is the front and back of the Heart.

Where is REN-14 located?

• A Manual of Acupuncture (p. 514): On the midline of the abdomen, 6 cun above the umbilicus and 2 cun below the sternocostal angle.
• Chinese Acupuncture and Moxibustion (p. 239): On the anterior midline of the abdomen, 6 cun above the umbilicus.

How is REN-14 Ju Que needled, and what lies beneath it?

Stated plainly: REN-14 lies on the midline just below the tip of the breastbone, and what is behind that part of the abdominal wall is the left lobe of the liver, with the diaphragm above it and, in some people, the heart and the sac around it within reach of a needle angled upward. It is the immediate neighbour of Jiu Wei REN-15, one of the small number of points to which the classical texts attach an explicit caution against needling, and it shares the same anatomy. The depth our own record carries is bounded for exactly that reason: 0.3 to 0.8 inch, which is among the shallower figures on the abdomen. Everything below is recorded as neutral reference data describing what the textbooks and the published imaging studies state. It is not instruction, this page does not teach technique, and needling is carried out only by a qualified, licensed practitioner.

The angle and depth the texts record

• Sacred Lotus sources & references record perpendicular insertion of 0.3 to 0.8 inch, with moxibustion applicable. For comparison within our own holdings, that ceiling is shallower than the 1 to 1.5 inch our records give for Zhong Wan REN-12 two cun below on the same line, where the abdominal wall is thicker and the liver edge further away.
• Deadman & Al-Khafaji (p. 514) and Chinese Acupuncture & Moxibustion (p. 239) record a comparable shallow range and both attach an explicit caution against deep or upward-angled insertion in this region, because upward angling directs the needle toward the diaphragm, the heart and the pericardium rather than along the abdominal wall.
• Moxibustion is recorded as applicable and is heavily used at this point. The ancient prescription record supports that directly: in the earliest textual prescriptions for epigastric pain, moxibustion was generally the method applied at Ju Que and its neighbours on the trunk (PMID 39943771). Moxa carries none of the depth hazard, which is part of why it dominates the historical record here.
• The xiphoid process defines the landmark, and it is the most variable part of the sternum — it may be short, long, forked, deflected forward or backward, or perforated. Since REN-14 is located two cun below the sternocostal angle, that variability affects where the point falls in relation to the ribs in a given person, and is part of why the reference texts describe the depth here conservatively.

The measured anatomy — and precisely which point each study measured

• Honest limit, stated first. No imaging or cadaveric study measuring a safe needling depth at CV-14 specifically could be located. The measurements that exist for this region were made at the point one cun below it, and every figure below is labelled with the point at which it was actually taken. No number is transferred to REN-14 as though it were its own.
• An MRI study that measured CV-15, not CV-14. Ten healthy adults of both sexes were scanned by MRI at Jiuwei CV-15 and safe depth derived for nine needling directions. The reported safe depths were 16.99 ± 2.86 mm for perpendicular needling, 22.72 ± 5.35 mm at 45° downward, 24.61 ± 2.92 mm at 45° upward and 53.47 ± 5.72 mm at 15° downward, with body mass index correlating with the dangerous depth in several directions and sex not (Cheng WP, Dong SP, Zhongguo Zhen Jiu 2012;32(6):515–518, PMID 22741258). The finding that carries across the region is the one about angle: the perpendicular direction has the shallowest tolerance, and the tolerance more than triples once the needle lies almost flat against the abdominal wall. These are CV-15's figures. They are recorded here because CV-14 is one cun away over the same structures and there is nothing closer — not because they describe this point.
• What lies behind, mapped in three dimensions — again at CV-15. A digital-visible-human study built a three-dimensional model of Jiuwei CV-15 from virtual Chinese human datasets to display the point and its adjacent tissue layer by layer. The authors concluded that CV-15 should be punctured obliquely downward to avoid injuring vital organs including the heart and liver, and gave a safe insertion depth of 1.0 to 1.5 cm (Zhongguo Zhen Jiu 2011;31(12):1097–1100, PMID 22256646). Again, CV-15. What the study establishes for this page is which structures occupy the space behind the lower sternum, and the answer is heart and liver.
• Where the liver actually is. The liver occupies the upper right of the abdominal cavity and extends leftward across the midline beneath the lower breastbone, sitting directly under the diaphragm; its upper surface rises well above the level of the lowest ribs. REN-14, six cun above the navel on the midline, lies over the left lobe of the liver in most adults. In a person whose liver is enlarged, it extends further down and further across, and the reference texts specifically note hepatomegaly as a circumstance in which the risk at points in this region is greater.
• The heart and the pericardium. The heart sits behind the lower sternum with its apex pointing down and to the left, separated from the abdominal wall by the diaphragm. The upward-angle caution in the reference texts exists for this reason. A systematic review of vascular injuries from acupuncture identified 31 published cases across the world literature, of which pericardial tamponade — bleeding into the sac around the heart — was the commonest serious event (Bergqvist D, Int Angiol 2013;32(1):1–8, PMID 23435388); the best-known such case followed needling through a congenital hole in the breastbone (Lancet 1995;345(8958):1175, PMID 7723561). Neither describes an injury at REN-14, and none is attributed to it here; they are cited for what they establish about the region.
• Liver injury from acupuncture is documented. A radiology case report describes acute haemoperitoneum — bleeding into the abdominal cavity — from direct liver injury caused by acupuncture (Seah EZ, J Radiol Case Rep 2023;17(8):15–20, PMID 37654899, PMC10435255). It does not name REN-14, and no injury is attributed to this point. It is cited because it establishes that a needle can reach and damage the organ the imaging studies place behind this part of the abdominal wall.
• No single agreed safe depth exists for any point. Two systematic reviews of the safe-depth literature — 33 studies in the first, 47 in the second — both concluded that measured depths for the same point differ greatly between subject groups and methods, and that "safe depth" has never been standardised (J Altern Complement Med 2011;17(3):199–206, PMID 21417806; Evid Based Complement Alternat Med 2013;2013:740508, PMID 23935678). The CV-15 study had ten subjects. It is the best measurement this region has, and it is still ten people, at a different point.

Risk in proportion

A meta-analysis of prospective clinical studies estimated serious adverse events in acupuncture at approximately 1 per 10,000 patients and around 8 per million treatments, with about half of all recorded events being bleeding, pain or flare at the needle site, placing acupuncture among the safer treatments in medicine (Bäumler P et al., BMJ Open 2021;11:e045961, PMID 34489268). A systematic review of the Chinese case-report literature from 1956 to 2010 found 1,038 adverse events across 167 articles and attributed them chiefly to improper technique rather than to acupuncture as such (He W et al., J Altern Complement Med 2012;18(10):892–901, PMID 22967282). REN-14 belongs to the small band of midline points beneath the breastbone where that small residual risk concentrates — which is why the classics warned about its neighbour, why every modern text bounds both, and why moxibustion dominates the historical record at this point.

What does the name Ju Que mean?

Ju Que means "Great Tower Gate" — ju, great or huge, and que, the watchtower or gate-tower that stood at the entrance to an imperial palace. Sacred Lotus sources & references translate it exactly that way. The name is a piece of classical political imagery used precisely: in the tradition the Heart is the monarch, the sovereign organ from which the spirit governs the rest of the body. A palace has a gate-tower before it, and REN-14 is that tower — the entrance to the sovereign's residence, standing directly in front of the Heart on the body's central line. Read that way the name states the classification: this is the front gate of the Heart, and the front gate of the Heart is what a Front-Mu point is.

The imagery is consistent across the neighbouring points. Shan Zhong REN-17 above is the "Chest Centre" and the Front-Mu of the Pericardium — the Heart's protective envelope, which classical theory calls the monarch's minister and bodyguard. Jiu Wei REN-15 below is the "Turtledove Tail", named for the shape of the xiphoid process rather than for any office. Ju Que is the only one of the three whose name is drawn from the palace itself.

Why does being the Heart's Front-Mu point matter?

Because it is the only one there is. Each of the twelve organs has exactly one Front-Mu point, and REN-14 is the Heart's. Confirmed by query in Sacred Lotus sources & references. Three things follow from that.

• It is a diagnostic point as well as a treatment point. Front-Mu points are palpated. Tenderness, resistance or a change in the tissue at REN-14 is read as an alarm referring to the Heart, and that is why the set is often called the alarm points. Diagnosis and treatment happen at the same spot.
• It is not on the Heart channel. The Heart channel runs from the armpit down the inner arm to the little finger and does not cross the trunk at all below the axilla. The Heart's Front-Mu point is therefore on the Conception Vessel — assigned by where the organ can be reached from the front, not by which line runs over the spot. The same is true of the Spleen's, on the Liver channel, and the Kidneys', on the Gallbladder channel.
• It pairs with a Back-Shu point. The Heart's Back-Shu point is Xin Shu BL-15, beside the fifth thoracic vertebra, confirmed by query and written up in this library alongside this record. Needling the two together — one on the front, one on the back, at roughly the same level of the trunk — is the Shu-Mu combination, the oldest structured pairing in the medicine. Front-Mu points are classically weighted toward acute and excess presentations, Back-Shu points toward chronic and deficient ones; using both is how a practitioner treats an organ from all sides at once.

Is there research on REN-14 Ju Que?

The honest answer is that REN-14 has very little point-specific modern research. It appears constantly in multi-point protocols and almost never as the subject of a study, and the most genuinely point-specific published work naming it is historical rather than clinical. That should be said plainly rather than padded out with whole-protocol trials.

• A historical data-mining study that names this point. Researchers at the China Academy of Chinese Medical Sciences assembled a dataset of the earliest recorded ancient acupuncture and moxibustion prescriptions for epigastric pain and analysed acupoint selection by frequency and association rules. The high-frequency base points were Zhong Wan CV-12, Shang Wan CV-13, Zu San Li ST-36, Nei Guan P-06, Gong Sun SP-04, Pi Shu BL-20 and Wei Shu BL-21; the recurring combination structures were Back-Shu with Back-Shu, Back-Shu with Front-Mu, Front-Mu with Yuan-Source, and Back-Shu with Lower He-Sea. On the trunk, moxibustion was generally the method used at Wei Shu BL-21, Pi Shu BL-20, Ge Shu BL-17, Zhong Wan CV-12, Ju Que CV-14 and Qi Hai CV-06, with Shang Wan CV-13 the exception (Zhongguo Zhen Jiu 2025;45(2):253–261, PMID 39943771). Two things in that are specific to this page: Ju Que is named individually, and it is named as a moxibustion point.
• An honest negative from the companion study. The same group applied the same method to the ancient prescriptions for chest obstruction and heart pain — the classical territory closest to REN-14's own indications. The high-frequency base points were Da Ling P-07, Nei Guan P-06, Tai Xi KI-03, Tai Chong LIV-03, Shang Wan CV-13, Yong Quan KI-01 and Xin Shu BL-15, and the authors summarised the governing principle as "the Pericardium acting on behalf of the Heart" (Zhongguo Zhen Jiu 2025;45(10):1505–1511, PMID 41074530). Ju Que does not appear among the high-frequency points in that analysis, while its Back-Shu counterpart BL-15 does. That is worth recording exactly as it stands: in the classical record for heart pain, the Heart's Back-Shu point was reached for more often than its Front-Mu point, and the Pericardium channel more often than either.
• Where the point appears without being tested. REN-14 recurs in modern protocols for insomnia, anxiety, palpitations, epigastric pain and functional dyspepsia, always as one point among many. Those studies measure protocols, not this point, and are not cited here as evidence about it.

What is missing should be said plainly: there is no randomised trial of REN-14, no sham-controlled study of it, no imaging study measuring safe depth at it, and none of its cardiac, digestive or spirit indications has been tested at this point specifically.

How does REN-14 compare with the points around it?

Jiu Wei REN-15 lies one cun below, directly beneath the xiphoid tip, and is the Connecting point of the Conception Vessel; the two share nearly all of their indications, and REN-15 is the one that carries an explicit classical caution against needling and has actually been measured by MRI. Where a Front-Mu classification is wanted, REN-14 is chosen; where the Conception Vessel's Connecting function is wanted, REN-15 is. Zhong Wan REN-12 lies two cun below REN-14 and is the Front-Mu of the Stomach and the Hui-Meeting point of the fu organs — the point to reach for when the complaint is squarely digestive rather than cardiac. Shan Zhong REN-17 higher on the breastbone is the Front-Mu of the Pericardium and the Hui-Meeting point of qi, and is REN-14's partner wherever the whole chest is congested. Xin Shu BL-15 on the upper back is its Back-Shu counterpart and its most important partner of all. Distally, Nei Guan P-06 at the wrist is the point that reaches the chest and the heart from a distance, and Lie Que LU-07 is the Confluent point of the Conception Vessel itself — where a treatment can be delivered from the limbs rather than from over the liver and the heart, the reference literature generally does so.
