Girdle Vessel
The one vessel that runs horizontally, encircling the waist like a belt and binding the vertical channels.
Pathway
The Girdle Vessel (帶脈, Dai Mai) is unique among the eight: it encircles the waist horizontally, at roughly the level of the umbilicus and lumbar spine, like a belt. Classical descriptions place it at LV-13 Zhangmen and GB-26 Daimai.
Because it runs around the body rather than up and down, the tradition says it "binds" the longitudinal meridians and keeps them from sagging or scattering.
Role in TCM theory
- Binding the channels — The Girdle Vessel is said to tie the vertical meridians together, especially the Liver, Gallbladder, Kidney, and Penetrating Vessel.
- The waist and lower back — Its horizontal route links it with low-back and abdominal patterns, and with the sensation of heaviness or weakness around the waist.
- Gynecological associations — Traditional texts connect the vessel with leukorrhea, menstrual irregularity, and prolapse patterns.
- A belt, not a river — Its unusual geometry makes it a useful image for the idea that not all channel flow is vertical.
Key points associated with the vessel
| Point | Name | Location | Traditional use |
|---|---|---|---|
| GB-26 | Daimai (帶脈) | At the level of the umbilicus, in the depression below the free end of the eleventh rib | The point that names the vessel; classically used for waist and gynecological patterns |
| GB-41 | Zulinqi (足臨泣) | On the dorsum of the foot, proximal to the fourth metatarsophalangeal joint | The confluent point of the Girdle Vessel; traditionally used for the side of the body and the waist |
| LV-13 | Zhangmen (章門) | On the lateral abdomen, below the free end of the eleventh rib | The front-mu point of the spleen and a classical meeting point for the vessel |
Point locations follow the WHO Standard Acupuncture Nomenclature (1991). The extraordinary vessels borrow points from the primary meridians; the table lists the points most closely associated with this vessel in standard references.
Confluent point
GB-41 Zulinqi is the confluent point of the Girdle Vessel; TB-5 Waiguan is its paired point on the Yang Linking Vessel. In clinical practice, the confluent point is the main point used when a practitioner wants to influence this vessel through acupressure or needling.
How this is viewed today
There is little modern research specifically on the Girdle Vessel. GB-26 and GB-41 are used clinically for waist and hip complaints, and GB-41 appears in trials for headache and neck pain. Press gently around the ribs and waist; avoid in pregnancy without professional guidance.
