Acupuncture Points on the Gall Bladder Channel of Foot Shao Yang
- Meeting Point of the Gallbladder Channel with the Girdling Vessel
What does GB-28 Wei Dao do?
GB-28 regulates the Girdling (Dai) vessel, and regulates the lower jiao and transforms stagnation — sharing its action with GB-27 just above it, at the front of the hip.
- Regulates the Girdling vessel — the Dai Mai, the belt-like horizontal vessel that binds the waist
- Regulates the lower jiao and transforms stagnation — moving what is stuck in the lower abdomen
A Girdling-vessel point, with GB-26 and GB-27. Our record classifies GB-28 as a Meeting Point of the Gall Bladder channel with the Girdling (Dai) vessel — the lowest of the three Gall Bladder points that meet the Dai on the abdomen (GB-26 Dai Mai, GB-27 Wu Shu and GB-28). It carries the same recorded action as GB-27 above it, and the two work together on the Dai vessel and the lower jiao. GB-41 on the foot is the vessel’s distal confluent point.
The uterine-prolapse note. GB-28’s indications add uterine prolapse to the shared Dai-vessel picture — the Dai vessel’s binding, holding-up function failing to keep the organs of the lower jiao in place. It is one of the points classically reached for in prolapse, though the modern management of prolapse is a medical and surgical matter.
On the name. “Wei Dao” means Linking Path or Tract of the Linking — wei to link, tie or connect, dao a path or way. The reading usually offered ties the name to the point’s role linking the Gall Bladder channel to the Dai vessel — the path of that connection.

What is GB-28 Wei Dao used for?
GB-28 is used for abnormal vaginal discharge, lower abdominal pain, hernia, and uterine prolapse. Our own indication record is reproduced here in full.
- Leucorrhoea (abnormal vaginal discharge) — the classical Dai-vessel disorder
- Lower abdominal pain
- Hernia
- Prolapse of the uterus
The Dai vessel’s holding function. Leucorrhoea and lower abdominal pain are the shared Dai-vessel-and-lower-jiao picture; uterine prolapse and hernia are the failure of the vessel’s binding, holding-up role — organs no longer held in place. It is a coherent Girdling-vessel list, weighted to the “holding” sense.
An honest note. Abnormal vaginal discharge requires medical assessment — infection is a common cause needing proper diagnosis and treatment. Uterine prolapse should be assessed medically; its management (pessaries, physiotherapy, surgery) is a medical matter, and this record documents a classical indication, not a treatment claim. A hernia requires assessment; a hard, painful one is a surgical emergency. Lower abdominal pain that is severe, sudden or persistent requires assessment. This record documents classical use only.
How it is combined. With GB-26 Dai Mai and GB-27 Wu Shu on the Dai vessel, with DU-20 Bai Hui and REN-06 Qi Hai for prolapse (lifting sunken qi), and SP-06 San Yin Jiao for discharge. All held here.

Where is GB-28 Wei Dao located?
GB-28 is on the side of the lower abdomen, just below and in front of the bony point of the hip, a little below GB-27.
- Anterior and inferior to (in front of and below) the anterior superior iliac spine — the bony hip prominence
- 0.5 cun anterior and inferior to GB-27 Wu Shu
- The lowest of the three Girdling-vessel Gall Bladder points on the abdomen
Found from GB-27 and the hip bone. Locate the anterior superior iliac spine (ASIS) at the front of the hip and GB-27 just in front of it; GB-28 sits half a cun below and forward of GB-27, tucked just below and in front of the hip bone. The two are close neighbours on the side of the lower abdomen.
On the name. “Wei Dao” — Linking Path, the path linking the channel to the Dai vessel, as noted above.

- A Manual of Acupuncture (p. 445): 0.5 cun anterior and inferior to Wushu GB-27.

How is GB-28 Wei Dao needled?
Our own record states perpendicular insertion of 0.5–1.0 inch, with moxibustion applicable. What follows is a neutral record of what the reference literature documents. It is not instruction, and this page does not teach technique.
- Angle and depth as recorded: perpendicular, 0.5–1.0 inch.
- Moxibustion: recorded as applicable.
- Regional anatomy: the point overlies the lateral abdominal wall (the oblique muscles) below and in front of the hip bone; deep to it lies the bowel in the lower abdomen, and in pregnancy the enlarging uterus; the iliac vessels run deeper in the pelvis.
Hazard, stated plainly. The consideration at a lower-abdominal point is the organs beneath — bowel, and in pregnancy the uterus; deep or careless needling of the lower abdomen in pregnancy is specifically to be avoided. Our record carries no arterial caution at GB-28, and it is not among the nine points that do. Not a point for self-treatment.
What is not claimed. No study measuring a safe depth at GB-28 could be located, and none is borrowed. No case report naming GB-28 was located.

Is there research on GB-28, and what should a reader know?
No trial isolates GB-28. Where the point appears it is one component of a gynaecological or lower-abdominal protocol, and a study that includes a point in a protocol is not evidence about that point.
What this page can state with confidence. GB-28 Wei Dao (“Linking Path”) is the lowest of the three Gall Bladder points meeting the Girdling (Dai) vessel (with GB-26 and GB-27), sharing GB-27’s action. Its indications — leucorrhoea, lower abdominal pain, hernia and uterine prolapse — reflect the Dai vessel’s binding, holding-up function. It sits just below and in front of the hip bone, half a cun from GB-27.
A safety note. Abnormal discharge and uterine prolapse are matters for medical care; this page records classical use and says so.
A note on searching for it. “GB 28”, “G 28” and “Weidao” searches return protocol trials and unrelated material — and “Weidao” matches Chinese personal and place names. Any claim attached to this point should be checked against what a study actually used.
