ST-29 (Gui Lai) Return

What does ST-29 Gui Lai do?

Gui Lai ST-29 is a lower-abdominal point of the Stomach channel and, in the recorded literature, one of the principal points for warming the uterus. Sacred Lotus sources & references summarise its practical use in a single line — it warms the Uterus and drives out cold pathogens — and that emphasis on cold is what separates it from its neighbours. It carries no five-shu, yuan, luo or meeting classification; its standing comes entirely from where it lies and from long clinical use, not from a category.

• Warms the lower jiao — the point's headline action. In the traditional framework, cold lodged in the lower burner contracts and obstructs; the recorded consequences are cold, cramping period pain, delayed or absent menstruation, and lower abdominal pain relieved by warmth. ST-29 is the point aimed at that pattern, and moxibustion rather than needling is the method most associated with it.
• Regulates menstruation — for irregular cycles, amenorrhoea and dysmenorrhoea, particularly where the presentation is cold or deficient rather than hot.
• Benefits the genital region — the recorded heading covering discharge, genital pain and the hernial disorders (shan) that the classical texts group with the genitals rather than with the abdominal wall.
• Raises what has descended — prolapse of the uterus appears in the point's recorded indications, and this is the sense in which the name Gui Lai, "Return", is most often read: the organ, or the cycle, returns to where it belongs.
• Moves stagnation in the lower abdomen — for lower abdominal pain and masses attributed to stagnant qi or congealed cold below the navel.

What is ST-29 Gui Lai used for?

Gui Lai ST-29 is used almost entirely for gynaecological and lower-abdominal complaints, with the cold and deficient presentations at the head of the list. The indications below are those recorded in the standard reference literature and describe traditional use, not proven treatment.

• Dysmenorrhoea (painful periods), especially with cold, cramping pain relieved by warmth
• Irregular menstruation
• Amenorrhoea (absent periods)
• Leucorrhoea (abnormal vaginal discharge)
• Prolapse of the uterus
• Infertility, in the traditional sense of failure to conceive attributed to cold in the uterus
• Lower abdominal pain
• Hernial disorders (shan), including pain radiating into the genitals
• Retraction or pain of the testicles
• Impotence
• Retention of urine

How is ST-29 Gui Lai used in practice?

Gui Lai lies on the lower abdomen two cun out from the midline and four cun below the navel — level with Zhong Ji REN-03, and therefore over the region of the uterus and the ovary rather than over the intestines. That position is why a point on the Stomach channel spends almost its whole clinical life in gynaecology. It is used bilaterally, and it is used above all where the presentation reads as cold.

• With Zhong Ji REN-03. The two lie at the same level, REN-03 on the midline and ST-29 two cun to either side, and they are the standard three-point row across the lower abdomen. REN-03 is the Front-Mu point of the Bladder and a Meeting Point of the three leg yin channels; ST-29 adds the warming, cold-dispelling emphasis on either side of it.
• With Guan Yuan REN-04 — the great tonification point of the lower burner, added where the underlying picture is deficiency and cold rather than obstruction, and where moxibustion is intended.
• With San Yin Jiao SP-06 — the crossing point of the Spleen, Liver and Kidney channels on the inner lower leg, and the standard distal partner for anything gynaecological. ST-29 is the local point, SP-06 the distal one.
• With Zi Gong Xue — the extra point on the lower abdomen whose name means "Palace of the Child" and which is most specifically associated with uterine prolapse. It sits lateral to REN-03 in the same row, and the two are used together for prolapse and for infertility. It is held in this library.
• With its own channel neighbours. Shui Dao ST-28 lies one cun above on the same line and is weighted toward the water passages and urinary difficulty; Qi Chong ST-30 lies one cun below and is a Meeting Point of the Stomach channel with the Penetrating Vessel, the "sea of blood", which gives it its own gynaecological standing. The three are frequently used along the line rather than singly.
• With the sacral points. Ci Liao BL-32 and its companions reach the same organs from behind; front-and-back combinations of ST-29 with the sacral foramen points are recorded for dysmenorrhoea.
• Method. Moxibustion is recorded as applicable, and at ST-29 it carries particular weight: a point whose recorded action is to warm the uterus and drive out cold is one where warming methods, including moxa boxes over the lower abdomen, are what the traditional indication actually calls for.

Where is ST-29 located?

• A Manual of Acupuncture (p. 151): On the lower abdomen, 2 cun lateral to the midline and 4 cun inferior to the umbilicus, level with Zhongji REN-3.
• Chinese Acupuncture and Moxibustion (p. 152): 4 cun below the umbilicus, 2 cun lateral to Zhongji (REN-3).

How is ST-29 Gui Lai needled, and what cautions are recorded?

Reference fact: ST-29 is a lower-abdominal point lying over the uterus, and the cautions the literature attaches to it are the lower-abdominal cautions — pregnancy, and depth in relation to the abdominal wall and the organs behind it. Sacred Lotus sources & references record perpendicular insertion of 0.7 to 1.2 inches with moxibustion applicable. Everything below records what the textbooks and published anatomical studies document. It is not instruction, and this page does not teach technique.

The angle and depth the texts record

• Sacred Lotus sources & references record perpendicular insertion of 0.7 to 1.2 inches, with moxibustion applicable.
• Chinese Acupuncture & Moxibustion (p. 152) and Deadman & Al-Khafaji (p. 151) record perpendicular insertion in a comparable range at the same site, with moxibustion applicable.
• What lies beneath. ST-29 sits over the belly of the rectus abdominis muscle, in the territory of the inferior epigastric vessels, which run up inside the rectus sheath roughly along this line. Bruising is the ordinarily documented occurrence at abdominal points on this line. Behind the abdominal wall at this level lie the bladder when full and, in pregnancy, the enlarging uterus.

Pregnancy — and a difference in our own record worth stating openly

The needling record held here for ST-29 carries no pregnancy caution, while the record for Zhong Ji REN-03 — the point at the same level on the midline, two cun away — carries an explicit one covering the Conception Vessel points from Qu Gu REN-02 to Shang Wan REN-13. That is an inconsistency in how the caution has been recorded across neighbouring points rather than a statement that ST-29 is safer, and it is flagged here rather than quietly harmonised. The standard reference literature treats the lower abdomen as a region requiring caution or avoidance in pregnancy as a whole, and lists the lower-abdominal points among those traditionally contraindicated. A reader should take the caution recorded at REN-03 as applying to this level of the abdomen generally, ST-29 included.

It is worth recording alongside the prohibition that the modern evidence for actual harm at the traditionally forbidden points is weak. A review of the scientific literature on those points found no objective evidence of harm across 15 clinical trials (823 women and several thousand treatments at one or more forbidden points), a cohort of 5,885 pregnant women, and animal work, with rates of preterm birth, miscarriage and stillbirth comparable to untreated controls (Carr DJ, Acupunct Med 2015;33(5):413–9, PMID 26362792). A later narrative review of randomised trials reached a similar conclusion about reported adverse outcomes (Med Acupunct 2019;31(6):346–360, PMID 31871522). The position stated on the Conception Vessel records in this library applies equally here: the traditional caution is long-standing and near-universal in the texts, the controlled evidence has not borne out the specific harm, and practitioners overwhelmingly continue to observe it.

Depth over the abdomen, stated as measured fact

• Recorded depth at abdominal points is not a constant. Studies measuring the distance from skin to underlying structures at abdominal acupoints found that the depth at which a therapeutic effect is sought can approach the depth at which underlying structures are reached, and that the margin narrows in overweight subjects and in older children (Complement Ther Med 2008;16(6):331–5, PMID 19028333; J Altern Complement Med 2009;15(9):1033–7, PMID 19715462).
• No single agreed safe depth exists for any point. Two systematic reviews of the safe-needling-depth literature — 33 studies in one, 47 in the other, measured by MRI, CT, ultrasound and cadaveric dissection — concluded that measured depths for the same point differ greatly between subject groups and measuring 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 bladder. The reference literature records that the lower abdominal points are used with the bladder empty, because a full bladder rises out of the pelvis and lies directly behind the abdominal wall at this level. That caution is stated most pointedly at REN-03, one level lower on the midline, and it applies to the whole row.
• Risk in proportion. A meta-analysis of prospective clinical studies estimated serious acupuncture-related adverse events at approximately 1 per 10,000 patients, with about half of all recorded events being bleeding, pain or flare at the needle site (Bäumler P et al., BMJ Open 2021;11:e045961, PMID 34489268).

What does the name Gui Lai mean?

Gui Lai means "Return" — gui, to go back or to return home, and lai, to come. Together they carry the sense of something coming back to where it belongs, and the commentaries read the name through the point's indications in three ways, all of which are consistent with the record held here. The menstrual reading is that a cycle which has stopped returns. The anatomical reading is that an organ which has descended — a prolapsed uterus, a retracted or descended testicle, both of which appear in the recorded indications — returns to its place. The fertility reading, the one most often quoted, is that the capacity to conceive returns. These are interpretations of a two-character name rather than separate documented facts, and it is worth saying so plainly; what is documented is the name, the translation, and the indications the name is read against.

Why does ST-29 have no point category?

Sacred Lotus sources & references record no five-shu, yuan, luo, xi-cleft, front-mu, back-shu or meeting classification for ST-29 — and that absence is informative rather than a gap. The great majority of the 361 channel points carry no special classification; the categories are a small structured minority. A point without one earns its place purely on where it lies and what it has been recorded as doing, which is exactly the case here: ST-29 is used because it sits directly over the uterus, not because it belongs to a system. This distinguishes it from its own immediate neighbour Qi Chong ST-30, one cun below, which is classified — as a Meeting Point of the Stomach channel with the Penetrating Vessel and as a Point of the Sea of Water and Grain — and from Zhong Ji REN-03 at the same level on the midline, which is a Front-Mu point and a three-channel Meeting Point. Where a classified point is wanted for the same region, those two are the ones the record points to.

Is there research on ST-29 Gui Lai?

Yes, but it is thin — one genuinely point-specific human study, and it is not about the point's traditional gynaecological use. Saying that plainly is more useful than assembling protocol trials that happen to include ST-29 in a list.

• The one point-specific human study. A prospective randomised study in 80 healthy male volunteers measured testicular blood flow by Doppler ultrasound during abdominal electroacupuncture. In the first stage, ST-29 (Guilai) was stimulated by simple needle insertion, by 2 Hz burst electroacupuncture, or by 10 Hz electroacupuncture. Only the 10 Hz stimulation of ST-29 increased testicular blood flow; needle insertion alone and 2 Hz burst stimulation did not. In the second stage, 10 Hz stimulation was applied at ST-25 (Tianshu) instead and produced no significant change (Fertil Steril 2008;90(5):1732–8, PMID 18076881). This is worth having for two reasons: it is one of the few studies to show a point- and frequency-specific physiological effect in humans, and its comparator is another point on the same channel that this library also holds — ST-25, the Front-Mu of the Large Intestine, seven cun higher on the same line. The study was in healthy volunteers and measured blood flow, not fertility; it does not show a clinical benefit.
• What the rest of the literature does not show. ST-29 appears frequently in multi-point protocols for polycystic ovary syndrome, infertility and dysmenorrhoea, and in point-selection data-mining reviews of infertility prescriptions. Those results describe the protocol or the prescribing habit, not this point, and they are not presented here as evidence for ST-29. No controlled trial of ST-29 alone for menstrual disorders, uterine prolapse or infertility was located.

How does Gui Lai compare with the points around it?

Shui Dao ST-28, one cun above on the same line, is the water-passage point of the group — its name means "Waterway" and it leans toward urinary difficulty and oedema where ST-29 leans toward the uterus. Qi Chong ST-30, one cun below, is where the Stomach channel meets the Penetrating Vessel, the "sea of blood", giving it a gynaecological role grounded in classification rather than in position alone. Zhong Ji REN-03, two cun medial at the same level, is the Front-Mu point of the Bladder and the point of choice when the complaint is urinary rather than uterine. Guan Yuan REN-04 is the tonification point of the whole lower burner. Zi Gong Xue, the extra point in the same row, is the one most specifically identified with uterine prolapse. Among all of these, ST-29 holds one distinct position that the others do not: it is the lower-abdominal point identified with cold in the uterus, and that — not its channel — is what selects it. All of the points named here are held in this library.
