ST25 (Tianshu / Heaven’s Pivot)

Practitioner Guide from The Acupuncture Supply Co.
Professional acupuncture supplies and practical clinical resources for qualified practitioners in Ireland and across Europe.

ST25, known as Tianshu (“Heaven’s Pivot”), is the Front-Mu point of the Large Intestine on the Stomach channel. Located bilaterally on the abdomen at the level of the umbilicus, it is traditionally used to regulate the intestines, transform accumulation and support the movement of Qi in the middle and lower Jiao.

Because ST25 overlies the abdominal cavity, accurate proportional measurement and patient-specific assessment are essential. Abdominal-wall thickness, pregnancy, distension, hernia, scars, previous surgery and the location of deeper viscera must inform technique. This is a professional reference for appropriately trained practitioners, not a universal needling prescription or self-treatment guide.

ST25 Tianshu quick reference

Point name	ST25 — Tianshu (“Heaven’s Pivot”)
Channel	Stomach channel of Foot Yangming
Classification	Front-Mu point of the Large Intestine
Region	Abdomen
Laterality	Bilateral
Core landmark	Level with the centre of the umbilicus, 2 B-cun lateral to the anterior median line

Location of ST25 Tianshu

The World Health Organization standard locates ST25 on the upper abdomen, 2 B-cun lateral to the centre of the umbilicus.

How to locate ST25

1. Position the patient comfortably supine, with the abdomen relaxed and appropriately draped.
2. Identify the centre of the umbilicus and establish a horizontal level through it.
3. Determine the patient’s proportional abdominal measurement rather than relying on the practitioner’s finger widths.
4. Measure 2 B-cun laterally on each side of the anterior median line.
5. Inspect and palpate gently for scars, hernia, guarding, tenderness, masses, pulsation, distension, skin change or unexpected anatomy.

ST25 is level with CV8 Shenque at the umbilicus. KD16 Huangshu lies 0.5 B-cun lateral to the umbilicus, while SP15 Daheng lies farther laterally at 4 B-cun. The patient’s proportional anatomy should guide location.

Traditional functions of ST25

• Regulates the intestines and supports the function of the Large Intestine.
• Regulates Qi and Blood in the abdomen.
• Transforms accumulation and resolves stagnation within traditional theory.
• Clears Damp-Heat from the intestines in an appropriate pattern.
• Warms and supports the intestines in selected Cold or deficiency patterns.
• Benefits the lower Jiao and may be included in selected gynaecological strategies.

These are traditional descriptions and should not be interpreted as claims that ST25 has been proven to diagnose, prevent or cure a gastrointestinal, gynaecological or other medical condition.

Traditional clinical applications

ST25 may be considered within an individualised treatment plan where pattern differentiation indicates presentations involving:

• Abdominal distension, discomfort or focal fullness.
• Constipation or difficult bowel movements.
• Loose stools or diarrhoea within a relevant traditional pattern.
• Irregular bowel function associated with Qi stagnation, Dampness, Heat, Cold or deficiency.
• Digestive weakness accompanied by abdominal symptoms.
• Selected menstrual or lower-Jiao presentations when the complete diagnosis supports its use.

New or severe abdominal pain, persistent vomiting, blood in the stool, unexplained weight loss, fever, bowel obstruction symptoms or a marked change in bowel habit requires appropriate medical assessment.

Common point combinations

• ST25 + ST37: a traditional Front-Mu and Lower He-Sea combination for intestinal regulation.
• ST25 + CV12: considered where harmonising the Stomach and intestines forms part of the strategy.
• ST25 + ST36: commonly selected to regulate digestion and support Qi.
• ST25 + SJ6: traditionally used in selected constipation patterns.
• ST25 + SP9: considered where Dampness or Damp-Heat contributes to intestinal symptoms.
• ST25 + LI4: used in some strategies to move Qi and regulate Yangming.

These are traditional examples, not fixed prescriptions. Point selection and technique should follow the complete diagnosis, medical history and the practitioner’s accredited training.

Anatomy and practitioner notes

• ST25 lies over the anterolateral abdominal wall, commonly in the region of rectus abdominis.
• Deeper layers may include rectus sheath, transversalis fascia, extraperitoneal tissue and parietal peritoneum; bowel may lie beneath.
• Abdominal-wall thickness and the position of deeper structures vary with body habitus, posture, pregnancy, distension and previous surgery.
• Ask about pregnancy, abdominal or pelvic surgery, hernia, mesh, stoma, inflammatory bowel disease, scars, implanted devices and current abdominal symptoms.
• Inspect and palpate for guarding, rebound-type tenderness, swelling, infection, bruising, altered sensation and unexpected pulsation or masses.
• Consider anticoagulant or antiplatelet medication, bleeding disorders, frailty, vasovagal history and needle sensitivity.
• Maintain respectful draping, clear consent and communication throughout abdominal assessment and treatment.

Needling and essential safety

ST25 is an abdominal point requiring careful anatomical judgement. Angle, depth and stimulation must be adapted to the individual patient and the practitioner’s accredited training. This guide deliberately does not prescribe a universal angle or depth.

• Avoid deep, uncontrolled or forceful insertion because excessive depth may enter the peritoneal cavity and threaten underlying viscera.
• Do not needle through infection, wounds, bruising, an active hernia, unexplained swelling or unsuitable tissue.
• Do not needle over uncertain post-surgical anatomy, mesh, a stoma, implanted device or an unexplained mass without appropriate clarification.
• Abdominal acupuncture during pregnancy requires specific obstetric acupuncture training, a clear rationale and recognised pregnancy-safety guidance.
• Use sterile, single-use needles with appropriate hand hygiene, clean-field and sharps-disposal procedures.
• Stop and reassess if sharp or increasing abdominal pain, guarding, marked dizziness, faintness, unusual bleeding or another unexpected response occurs.

Moxibustion

Moxibustion is traditionally considered at ST25 in selected Cold or deficiency patterns. Maintain continuous supervision and protect the skin. Avoid moxa where sensation is impaired, skin is inflamed or damaged, heat is unsuitable, or pregnancy-related guidance excludes abdominal heat application.

When urgent medical assessment takes priority

Urgent assessment is required for sudden or severe abdominal pain; a rigid or guarded abdomen; persistent vomiting; vomiting blood; black or bloody stool; marked distension with inability to pass stool or gas; collapse; heavy vaginal bleeding; suspected ectopic pregnancy; or fever with worsening pain. Persistent deep pain, shoulder-tip pain, faintness or unusual illness after abdominal needling also warrants prompt medical evaluation.

Research note

ST25 appears in acupuncture studies of gastrointestinal and metabolic presentations, usually within multi-point protocols. Inclusion does not establish the independent effect of ST25, and results should not be generalised across conditions, techniques or populations. Traditional functions and clinical research should be presented separately.

Frequently asked questions

Where exactly is ST25 located?

ST25 is level with the centre of the umbilicus and 2 B-cun lateral to the anterior median line on each side.

What does Tianshu mean?

Tianshu is commonly translated as “Heaven’s Pivot”, reflecting the point’s traditional role in regulating the central movement between upper and lower.

Why is ST25 called the Front-Mu point of the Large Intestine?

In traditional channel theory, Front-Mu points are anterior points associated with particular Zang-Fu systems. ST25 is associated with the Large Intestine.

Can patients use this guide for self-needling?

No. ST25 overlies the abdominal cavity and requires anatomical knowledge, sterile technique and professional assessment.
