Hua Tuo Jia Ji Hua Tuo's Paravertebral Points

What do the Hua Tuo Jia Ji points do?

Hua Tuo Jia Ji is not one point. It is a paired series running the whole length of the spine, one pair beside each vertebra, and what it does depends entirely on which level is chosen. That single fact governs everything else on this page. A Jia Ji point is selected by vertebral level to match the region or the internal organ served by that spinal segment — upper thoracic levels for the chest and upper limbs, mid and lower thoracic levels for the digestive organs, lumbar levels for the low back, pelvis and legs. The series belongs to no channel, so it carries no channel-theory action; everything below is derived from documented clinical use.

• Acts segmentally, level by level — the defining property of the series. The point is not chosen for a pattern but for a place: the practitioner establishes which spinal level corresponds to the complaint and needles beside that vertebra. This is why one point name covers complaints as different as neck pain, wheezing, indigestion and sciatica.
• Relieves local spinal and paravertebral pain and stiffness — pain, muscular tension and restricted movement of the neck, mid back and low back, treated directly at the level involved. This is the most common documented use of the series by a wide margin.
• Relieves pain radiating along the segment — pain travelling from the spine into the arm, the chest wall or the leg is treated at the level from which it radiates. The best-documented example is the band of pain of shingles (herpes zoster) and the neuralgia that can follow it, treated at the spinal level of the affected band (PMID 32227773).
• Used for disorders of the internal organs served by the level chosen — recorded in the modern reference literature and studied in trials for digestive complaints as well as musculoskeletal ones (PMID 30773861, PMID 16136930). This is documented clinical usage organised around the segmental nerve supply of each level, and it is set out honestly as that rather than as a channel or organ-theory mechanism.
• Used for limb weakness and spasticity after neurological injury — a large, mostly modern body of clinical work applies the series after stroke and after spinal cord injury, needling the levels that supply the affected limb (PMID 40825684, PMID 35218626).

A correction worth stating plainly. Our own earlier record described these points as "clearing the channel" and as "regulating the qi and blood of the corresponding zang-fu organ". Neither phrase can be sustained. Hua Tuo Jia Ji lies on no channel — the series has no five-shu, yuan, luo, xi-cleft, back-shu or front-mu classification, and there is no channel running along the Jia Ji line to clear. The points that genuinely carry the organ relationship down the back are the Back-shu points of the Bladder channel, which run parallel to the Jia Ji line and further out from the midline: BL-13 Fei Shu for the Lungs, BL-15 Xin Shu for the Heart, BL-18 Gan Shu for the Liver, BL-19 Dan Shu for the Gallbladder, BL-20 Pi Shu for the Spleen, BL-21 Wei Shu for the Stomach, BL-23 Shen Shu for the Kidneys, BL-25 Da Chang Shu for the Large Intestine, BL-27 Xiao Chang Shu for the Small Intestine and BL-28 Pang Guang Shu for the Bladder — all held in Sacred Lotus sources & references. On the midline itself runs the Governing vessel, with DU-14 at the base of the neck, DU-04 Ming Men in the lumbar region and DU-03 Yao Yang Guan below it. The reader loses nothing by the correction: the organ relationship is real, it simply belongs to the points on either side of the Jia Ji line rather than to the Jia Ji points themselves, and knowing which is which is the reason for holding all three sets.

What is Hua Tuo Jia Ji used for?

Because the series runs the length of the spine, its indications are organised by vertebral level rather than as one flat list — the level chosen is the indication. The bands below are those carried in Sacred Lotus sources & references and are the standard modern teaching. Read the list as "for this complaint, these levels", not as a set of separate points each doing something different.

• C1–C7 — disorders of the neck region: neck pain and stiffness, cervical spondylosis, cervicogenic headache, dizziness of cervical origin (see the discrepancy note below on the cervical levels)
• T1–T4 — disorders of the upper limbs and the Lungs: shoulder and arm pain, cough, wheezing, asthma
• T4–T8 — disorders of the Heart and chest: chest pain and oppression, palpitations, intercostal pain
• T7–T10 — disorders of the Liver and Gallbladder: hypochondriac pain, jaundice, gallbladder complaints
• T10–T12 — disorders of the Spleen and Stomach: epigastric pain, abdominal distension, indigestion, vomiting
• L1–L2 — disorders of the Kidneys: lumbar pain, urinary complaints
• L3–L5 — disorders of the Bladder, Large and Small Intestines, Uterus and lower limbs: low back pain, sciatica, lumbar disc complaints, intestinal and menstrual disorders, weakness of the legs
• Any level — herpes zoster (shingles) and post-herpetic neuralgia, treated at the spinal level of the affected band of skin
• Any level — pain, stiffness, muscular tension and restricted movement of the paravertebral region at that level
• Multiple levels — limb weakness and spasticity following stroke or spinal cord injury, treated at the levels supplying the affected limb

On the cervical levels. Classically — per Deadman & Al-Khafaji, following the description attributed to Hua Tuo — the 34 Jia Ji points span only the twelve thoracic and five lumbar vertebrae, T1 to L5, which is exactly the range our own location record carries. The extension upward to the cervical levels C1–C7, referenced in the band list above, reflects a later and now very widespread clinical usage taught in modern acupuncture and in related bodywork traditions rather than the classical 34-point set. Both are recorded here because both are in real use, and the modern clinical literature works with the cervical levels routinely — trials of "cervical Jiaji" or "neck-Jiaji (EX-B2)" for cervical spondylosis, cervicogenic headache and cervical vertigo are numerous (for example PMID 39114722, PMID 26946730, PMID 25509734, PMID 40825705). The honest position is that our location field describes the classical series while the indication bands describe modern practice, and a reader should know that the two do not have the same span.

How is Hua Tuo Jia Ji used in practice?

The first thing to understand is that Hua Tuo Jia Ji is a series, not a point, and that our library holds it as one record rather than as thirty-four separate ones. We queried this directly: Sacred Lotus sources & references hold a single Hua Tuo Jia Ji record covering the whole series, with no individual records for the separate levels. That matches the reference texts, where Deadman & Al-Khafaji and Chinese Acupuncture & Moxibustion both describe the set as one entry — every member shares the same relationship to its vertebra and differs only in level.

How are the Hua Tuo Jia Ji points counted?

In the standard modern definition there are 34 points: 17 on each side, one beside each of the twelve thoracic and five lumbar vertebrae, from T1 down to L5. Each sits a short distance out from the depression below the tip of that vertebra's spinous process, on the ridge of muscle either side of the midline. Our location record gives that lateral distance as 0.5 to 1 cun, the range the reference texts carry. Beyond that standard set, three variations are in genuine circulation and are worth knowing:

• The cervical extension. Most modern practice adds pairs beside the cervical vertebrae, giving up to 48 points in all. The published clinical literature works with these routinely under names such as "cervical Jiaji" and "neck-Jiaji (EX-B2)". They are not part of the classical 34, and the discrepancy is flagged in the indications above.
• The lateral distance. The reference literature records anything from 0.3 cun to 1 cun out from the midline depending on the source and the region. A cadaveric study of the lower lumbar levels measured what a needle reaches at 0.3, 0.5 and 1 cun lateral and concluded that the Jiaji location is better understood as a band running from about 0.3 to 1 cun than as a single line, because the relevant nerve branch and its accompanying vessels are distributed across that whole strip (Zhongguo Zhen Jiu 2012;32(2):139–42, PMID 22493919). That is a useful modern reconciliation of a long-standing textual disagreement.
• The Taoist reading. In Taoist internal practice "Jiaji" is not a point at all but a pass — Jiaji Guan, one of the three gates along the spine — understood as a deep three-dimensional region on the central axis of the back rather than as a pair of surface locations. A 2023 textual study set the two readings side by side and concluded that medical writers concentrate on the distance lateral to the spine while Taoist writers concentrate on the spine itself (Zhongguo Zhen Jiu 2023;43(9):1070–5, PMID 37697884). Anyone reading older or qigong-influenced sources will meet the second sense and should not confuse it with the acupuncture points.

Which points is Hua Tuo Jia Ji combined with?

• With the Back-shu points of the Bladder channel — BL-13 Fei Shu, BL-15 Xin Shu, BL-18 Gan Shu, BL-20 Pi Shu, BL-23 Shen Shu, BL-25 Da Chang Shu and their neighbours, which lie on the same horizontal line and further out from the Jia Ji point. This is the commonest pairing of all: the Jia Ji point for the segment, the Back-shu point for the organ. A clinical trial in ulcerative colitis combined Jiaji needling with plum-blossom tapping at BL-22 and BL-25 (J Tradit Chin Med 2005;25(2):83–4, PMID 16136930).
• With the Governing vessel on the midline — DU-14 at the base of the neck, DU-04 Ming Men in the lumbar region and DU-03 Yao Yang Guan below it, all held in Sacred Lotus sources & references. The three lines — Governing vessel on the midline, Jia Ji beside it, Back-shu outside that — are treated as a set.
• With Ding Chuan — the extra point beside DU-14 at the base of the neck, which is in effect a Jia Ji point of that level given its own name and its own indication for wheezing and asthma. Reading the two records together is the clearest way to see how a Jia Ji point behaves, and Ding Chuan's record carries the same pneumothorax caution for the same anatomical reason.
• With Shi Qi Zhui Xia and Yao Yan — the lumbar extra points, added for low back complaints alongside the L3–L5 Jia Ji pairs. Both are held here.
• With distal points for the limb involved — GB-34 Yang Ling Quan and ST-36 Zu San Li for the leg, LI-11 Qu Chi and LI-15 for the arm. A randomised trial in stroke patients added Jiaji points from C4 to T5 on top of exactly that kind of conventional distal prescription and reported greater gains in upper-limb motor scores than the distal points alone (PMID 40825684).
• With Ashi points and local trigger points — a randomised trial of upper back myofascial pain combined bloodletting at local trigger points with needling at Jiaji points (J Tradit Chin Med 2016;36(1):26–31, PMID 26946615).

Why is Hua Tuo Jia Ji so heavily used in modern practice?

Three reasons, worth separating. First, coverage: a set running from the neck to the sacrum can be brought to bear on almost any complaint that has a spinal level, which no single point can. Second, a shared logic with modern anatomy: the segmental organisation of the series maps readily onto the segmental organisation of the spinal nerves, which has made it the point set of choice both for practitioners working alongside conventional medicine and for researchers designing protocols. Third, the electroacupuncture fit: paired points at the same level on either side of the spine are convenient to connect to a stimulator, and most modern research on the series uses electroacupuncture rather than plain needling. The result is that Hua Tuo Jia Ji is now among the most-used point sets in Chinese hospital practice and carries a research base larger than that of many named channel points.

Where is Hua Tuo Jia Ji located?

• A Manual of Acupuncture (p. 573): 0.5 to 1 cun lateral to the depressions below the spinous processes of the twelve thoracic and five lumbar vertebrae.

How are the Hua Tuo Jia Ji points needled, and what makes them a high-risk series?

Stated plainly before anything else: the hazard at a Hua Tuo Jia Ji point is not one hazard but three, and which applies depends entirely on the level. Beside the neck the concern is the spinal canal and the vertebral artery; beside the thoracic vertebrae it is the lung, and pneumothorax following needling at these points is documented in the published case literature; beside the lumbar vertebrae it is the kidney and the retroperitoneal space. No other record in this library covers so much of the trunk, and no single depth figure describes the whole series. Everything below records what the standard texts and the published imaging, cadaveric and case literature document. It is not instruction, and this page does not teach technique. Needling is carried out only by a qualified, licensed practitioner.

The angle and depth the texts record

• Sacred Lotus sources & references record perpendicular-to-oblique insertion directed towards the spine, 0.5 to 1 cun, with an explicit caution that in the thoracic region the needle is angled obliquely towards the spine rather than perpendicularly and that excessive depth is avoided because of the pleura beneath.
• Deadman & Al-Khafaji (p. 573) and Chinese Acupuncture & Moxibustion (pp. 245–246) record a comparable range and the same medially-angled direction. The reason for that direction is structural rather than stylistic: angling in towards the vertebral lamina puts bone behind the needle instead of a body cavity.
• Moxibustion is recorded as applicable along the series.
• Most of the modern clinical literature on these points uses electroacupuncture, pairing points at the same level. That is a safety fact as well as a technical one: an autopsy case report of fatal bilateral pneumothoraces following electroacupuncture concluded that electrical pulses and the muscle contraction they provoke may draw needles deeper than the depth at which they were placed (J Forensic Sci 2022;67(1):377–383, PMID 34435369).

The thoracic levels — the pneumothorax hazard, documented at this point set

This is not a theoretical risk carried over from neighbouring points. It has been reported at Hua Tuo Jia Ji specifically. A 2024 case report describes a patient who received acupuncture at the Huatuo-Jiaji points for a digestive complaint and afterwards developed breathlessness and chest pain. Neither the patient nor the practitioner suspected a punctured lung at the time; chest radiography the following day confirmed a right-sided haemopneumothorax — air and blood together in the pleural space — and the patient was admitted, treated with oxygen and medication, discharged after six days, readmitted when the pneumothorax recurred, and confirmed fully resolved only on day twenty (Heliyon 2024;10(13):e34190, PMID 39071604, DOI 10.1016/j.heliyon.2024.e34190). The authors' conclusion is the one that matters here: clinicians needling over the thoracic back should actively look for these symptoms rather than wait to be told about them.

• How common pneumothorax is overall. A systematic review of the Chinese case-report literature from 1956 to 2010 identified 1,038 adverse-event cases across 167 articles, of which 307 were pneumothorax — second only to fainting. Thirty-five deaths were recorded across the whole series. The authors attributed the events chiefly to improper technique and concluded that most were avoidable through standardised training (He W et al., J Altern Complement Med 2012;18(10):892–901, PMID 22967282).
• The measured margin over the upper back. The pleural anatomy behind these points has been mapped directly. A dissection study of 46 adult bodies measured the projection of the dome of the pleura against the points around it, naming Ding Chuan EX-B1 and Da Zhu BL-11 among others, and found it varied widely between individuals, reaching beyond the medial third of the clavicle in almost 60 per cent of bodies; the authors concluded that when a point is located and angled as the standard describes the pleura is not reached, but that exceeding the recorded depth breaches the pleural membrane (Zhongguo Zhen Jiu 2006;26(5):346–8, PMID 16739850). Ultrasound measurement at the neighbouring GB-21, taken in 101 adults, put the distance from skin to the pleural line at 17.4 mm in men and 14.6 mm in women — under a centimetre and a half in the average woman (J Acupunct Meridian Stud 2018;11(6):355–360, PMID 29936338).
• Body size changes the margin. A retrospective CT study measured safe needling depths at 23 upper back points in patients aged 4 to 18 and found significant differences by sex, age, weight and body mass index, with weight the strongest single determinant (BMC Complement Altern Med 2016;16:85, PMID 26922245). A textbook depth is a description of an average adult body, not a constant.
• Delayed presentation. As the case above shows and the reference literature notes, a pneumothorax after needling over the thorax may not declare itself immediately, presenting hours later with sudden chest pain, breathlessness or a persistent dry cough. It is a medical emergency requiring immediate assessment.

The lumbar levels — the kidney and the retroperitoneal space

Below the ribs the lung is no longer the concern and the kidney is. The kidneys lie retroperitoneally against the posterior abdominal wall at roughly the T12 to L3 levels, so the upper lumbar Jia Ji pairs sit over the kidney region in the same way BL-23 Shen Shu does, and the standard cautions for the lumbar region apply for the same reason. Our BL-23 record sets out the imaging evidence for that region in detail.

• What a needle reaches at the lumbar levels has been measured. A cadaveric study of thirty adult male spines inserted needles perpendicularly at 1 cun, 0.5 cun and 0.3 cun lateral to the lower border of the lumbar spinous processes. At 1 cun lateral the tip reached the facet joint and its adjacent bony canal at a depth of 35.77 ± 5.86 mm, contacting the medial branch of the dorsal ramus of the spinal nerve and its accompanying vessels; at 0.5 and 0.3 cun lateral the corresponding depth was 32.89 ± 4.79 mm. The authors concluded that the nerve branch is distributed across the whole 0.3-to-1-cun band, which is both the anatomical basis of the point and the reason the recorded depth is bounded (Zhongguo Zhen Jiu 2012;32(2):139–42, PMID 22493919).
• Deep needling at the lumbar levels is a specialist imaging-guided technique, not the textbook depth. A CT study of lumbar Jiaji needling for lumbar disc prolapse examined the depth and angle at which the tip could be brought to the posterior epidural space and reported that an insertion angled 20 to 30 degrees to the sagittal plane was what reached it (Zhongguo Zhen Jiu 2005;25(3):179–80, PMID 16312926). A three-arm randomised trial in 165 patients with lumbar disc herniation went further, comparing CT-verified deep needling at the intervertebral foramen to a mean depth of 5.91 ± 0.67 cm against conventional-depth needling and against standard Huatuo Jiaji acupuncture; the deep group did better on pain, function and disability scores at four and twelve weeks, and no serious adverse events were reported in any arm (Pain Res Manag 2026;2026:9030734, PMID 42365469). These figures are recorded because a reader comparing such trials with the reference texts will otherwise find the two irreconcilable — they describe hospital procedures performed under imaging, not the depth the general texts give.
• For scale in the same region, an MRI study of 148 adults measured the depth at which straight needling at Da Chang Shu BL-25, out from the L4 Jia Ji point, would pass beyond the muscle: 11.2 ± 1.3 cm on the left and 11.0 ± 1.2 cm on the right in men, and 9.8 ± 1.3 cm and 9.7 ± 1.3 cm in women, correlating positively with body mass index (Zhongguo Zhen Jiu 2022;42(4):402–4, PMID 35403399).

The cervical levels — the spinal canal and the vertebral artery

Beside the neck the structures beneath are the vertebral canal with the spinal cord inside it and, further forward, the vertebral artery in its bony canal. The tissue cover here is thinner than anywhere else along the series.

• The layers have been imaged. An ultrasound study in twenty healthy adults imaged the cervical Jiaji point at C5 and measured the distance from the skin surface down through each successive layer — subcutaneous tissue, trapezius, splenius capitis, semispinalis capitis, semispinalis cervicis, multifidus, and finally the vertebral arch. Every layer depth differed significantly between men and women, and the sensation reported by the subject changed measurably as each layer was entered (Zhongguo Zhen Jiu 2015;35(9):931–4, PMID 26721153). The practical content of that finding is that at the cervical levels the bone is the backstop and the distance to it is individual.
• Bone landmarks have been used to define the margin on the posterior neck in a study of 29 skulls, 197 dry cervical vertebrae and 31 lateral cervical radiographs, mapping the vertebral canal against the palpable spinous processes (BMC Complement Med Ther 2024;24(1):168, PMID 38649990).

Risk in proportion

None of the above says this is a dangerous series in ordinary use. A meta-analysis of prospective clinical studies estimated serious acupuncture-related adverse events at approximately 1 per 10,000 patients and about 8 per million treatments (Bäumler P et al., BMJ Open 2021;11:e045961, PMID 34489268), and a 2024 review of the safety literature put serious events at roughly 0.04 to 0.08 per 10,000 treatments, identifying deep needle penetration, incorrect point selection and improper manipulation as the contributing factors and concluding that most such events are preventable (Am J Chin Med 2024;52(6):1555–1587, PMID 39460372). The bounded depth, the medial angle and the level-by-level awareness described above exist to keep it that way.

What does the name Hua Tuo Jia Ji mean?

The name is a person plus a place. Hua Tuo is the name of a physician; jia means to flank or press in on both sides; ji means the spine. "Hua Tuo's points that flank the spine" is the sense of it, and it describes the series exactly. Hua Tuo (c. 140–208 CE) is among the most famous figures in Chinese medicine, remembered chiefly as a surgeon and as the originator of the Wu Qin Xi five-animal exercises. The attribution of this series to him is traditional rather than documented from his own hand — none of his own writing survives — and a study of his contribution to acupuncture examines what can and cannot be credited to him (Zhongguo Zhen Jiu 2015;35(12):1305–7, PMID 26964188). The set is often shortened simply to Jia Ji, and carries the modern code EX-B2 ("extra point, back, number 2"), with the older code M-BW-35 still appearing in some references.

Where does the Hua Tuo Jia Ji series come from?

The earliest surviving description of points beside the spine used as a set appears in Sun Simiao's Qian Jin Yao Fang ("Essential Formulas Worth a Thousand Gold Pieces", seventh century), which records needling either side of the vertebrae — the passage later writers took as the record of Hua Tuo's method. The standardisation into a numbered set of 34 points from T1 to L5 at a fixed distance lateral to each spinous process is a twentieth-century development, and the cervical extension in wide use today is more recent still. Two things follow, and both are worth holding onto: the series is old in principle and modern in its present form, and the disagreements between sources about how far out from the midline the points sit are inherited from the texts rather than invented by any one school.

How does Hua Tuo Jia Ji compare with the Back-shu points?

They run in parallel, they are used together constantly, and they are not the same thing. The Jia Ji points sit closest to the midline — the reference literature places them from about 0.3 to 1 cun out from the depression below each spinous process. The Back-shu points of the Bladder channel run down the same back at 1.5 cun from the midline, so further out from the Jia Ji point at the same level. The difference that matters is one of kind, not distance. A Back-shu point is a named channel point with a named organ — BL-13 Fei Shu is the point of the Lungs, BL-23 Shen Shu the point of the Kidneys — and carries the full apparatus of channel theory, including a front-mu partner on the front of the body. A Jia Ji point is an extra point with no channel and no organ of its own; what it has is a level. In practice that makes the Back-shu points the choice where the reasoning is about an organ and a pattern, and the Jia Ji points the choice where the reasoning is about a segment, a spinal level, or a local problem in the back itself. Between the two lines, on the midline, runs the Governing vessel with DU-14, DU-04 Ming Men and DU-03 Yao Yang Guan. All three sets are held in Sacred Lotus sources & references, and the three-line arrangement is the simplest way to hold the back in mind.

Is Hua Tuo Jia Ji a channel point?

No. It is an extra point — in fact the largest extra point series in the repertoire. Extra points sit outside the fourteen channels: they were recorded for an observed clinical effect rather than derived from channel theory, so they carry no five-shu, yuan, luo, xi-cleft, back-shu or front-mu classification. That is why our record shows no channel and no point categories, and why the actions above are framed as documented uses rather than as channel mechanics. The organ relationships a reader may have seen attached to these points belong properly to the Back-shu points named above.

Is there research on Hua Tuo Jia Ji?

Yes — considerably more than for most extra points, and more than for many channel points. This is the best-researched extra point in the library. Several hundred indexed papers name Jiaji or EX-B2, and unlike the multi-point protocol studies that dominate acupuncture research, a substantial share of them are designed around this series specifically. The quality is uneven, and much of it appears in Chinese-language journals with the methodological limitations that entails, so it is set out here with that qualification attached.

• Shingles pain. A randomised controlled trial in 140 outpatients with post-herpetic neuralgia added electroacupuncture at Jiaji points to a baseline of local electroacupuncture, moxibustion and intermediate-frequency therapy. The treatment group had lower anxiety scores throughout and lower pain scores at the fifth and tenth treatments, though the control group scored better at the later sessions — a mixed result, reported here as it stands (J Tradit Chin Med 2020;40(1):121–7, PMID 32227773).
• Stroke rehabilitation. A randomised trial in 62 patients with upper-limb motor impairment after stroke added Jiaji needling from C4 to T5 to a conventional prescription of LI-15, LI-11, LI-10, GB-30, GB-34 and ST-36. The Jiaji group showed larger increases in motor evoked potential amplitude and shorter latencies in two hand muscles, alongside better Fugl-Meyer and Wolf motor function scores (Zhongguo Zhen Jiu 2025;45(8):1037–41, PMID 40825684). A separate randomised trial combined Jiaji needling with core muscle training for lower-limb function after stroke (Zhen Ci Yan Jiu 2022;47(2):154–9, PMID 35218626).
• Cervical complaints. Trials of cervical Jiaji for cervical spondylosis and cervicogenic headache are numerous (for example PMID 39114722, PMID 26946730, PMID 25509734). A 2025 dose-response meta-regression of 19 randomised trials in 747 patients with cervical vertigo, all using a core prescription of DU-20, GB-20 and neck-Jiaji, found a non-linear relationship between the number of sessions and the outcome, with vertebrobasilar blood-flow measures peaking at about fourteen sessions (Zhongguo Zhen Jiu 2025;45(8):1180–6, PMID 40825705). That is an unusual and genuinely useful finding, because it addresses how much treatment rather than merely whether.
• Back and neck muscular pain. A randomised trial in upper back myofascial pain syndrome combined bloodletting at local trigger points with Jiaji needling (J Tradit Chin Med 2016;36(1):26–31, PMID 26946615), and a randomised trial in elderly patients with chronic low back pain from lumbar disc herniation used a yin-yang regulation method built on the lumbar Jiaji points (Zhongguo Zhen Jiu 2025;45(5):620–6, PMID 40369918).
• Digestive and other internal complaints. Randomised and observational work covers gastrointestinal dysfunction in sepsis (Zhen Ci Yan Jiu 2019;44(1):43–6, PMID 30773861; Zhongguo Zhen Jiu 2019;39(10):1055–8, PMID 31621256) and ulcerative colitis (PMID 16136930). These are the studies that give the segmental organ indications above such modern support as they have.
• Laboratory work. A large experimental literature applies electroacupuncture at Jiaji points in animal models of spinal cord injury, neuropathic pain, intervertebral disc degeneration, allergic asthma and myocardial ischaemia–reperfusion, examining inflammatory and apoptotic signalling pathways (for example PMID 39557428, PMID 40059047, PMID 40551645, PMID 40262939, PMID 40551649, PMID 33376501). This body of work is mechanistic rather than clinical and does not by itself establish clinical benefit, but its volume is one reason the series occupies the place it does in modern Chinese practice.

The fair summary: Hua Tuo Jia Ji is a modern workhorse with a research base unusually large for an extra point, concentrated on spinal and neurological conditions, largely Chinese-language, largely positive, and largely of moderate methodological quality. The general evidence on acupuncture for chronic musculoskeletal pain — an individual patient data meta-analysis of 39 trials and 20,827 patients finding effects of roughly 0.5 standard deviations against no-acupuncture control and about 0.2 against sham, persisting with only a small decline at one year (Vickers AJ et al., J Pain 2018;19(5):455–474, PMID 29198932) — is the frame within which the point-specific work should be read.
