LI-12 (Zhou Liao) Elbow Bone Hole

What does LI-12 Zhou Liao do?

LI-12 activates the channel, alleviates pain, and benefits the elbow joint — a purely local point, its whole recorded action being the elbow it sits on.

• Activates the channel and alleviates pain — the general channel action
• Benefits the elbow joint — the local action, and the reason to reach for it

A local point, and honestly so. Many points carry a spread of distal and organ actions; LI-12 does not. Both recorded actions are about the elbow, and its single indication is elbow-and-arm pain. It is a point you use for the joint it lies beside — the neighbouring LI-11 Qu Chi, one cun below at the elbow crease, is the major point of the region, and LI-12 is its local supporting point on the bone just above.

On the name and the “liao” points. “Zhou Liao” means Elbow Bone Hole — zhou the elbow, liao a bone hole, crevice or bony hollow. A whole family of points carries liao in the name for the hollow beside a bone they occupy: our data holds the four sacral liao (BL-31 to BL-34, the Upper/Second/Middle/Lower Bone Holes), ST-03 Ju Liao, GB-29 Ju Liao, LI-19 He Liao and others. LI-12 is named the same way, for the crevice on the border of the humerus where it sits.

What is LI-12 Zhou Liao used for?

LI-12 is used for pain, numbness and contracture of the elbow and arm. Our own indication record is reproduced here in full — a single, tightly local entry.

• Pain of the elbow and arm
• Numbness of the elbow and arm
• Contracture (stiffness with inability to straighten) of the elbow and arm

One region, three ways it presents. Pain, numbness and contracture are the elbow disorder described from three angles, and that is the whole of it — LI-12 is not a systemic point and our record does not present it as one. It sits among the classical points for tennis elbow (lateral epicondylitis) and elbow stiffness, used with its neighbours for the joint.

An honest note. New numbness or weakness of an arm requires medical assessment — sudden onset can be neurological and needs same-day care, and persistent numbness can mean nerve compression. Elbow pain that follows an injury, or comes with swelling, locking or fever, needs assessment rather than repeated self-treatment. This record documents classical use only.

How it is combined. With LI-11 Qu Chi at the elbow crease and LI-10 Shou San Li just below — the local cluster for the lateral elbow. With SJ-05 Wai Guan and LU-05 Chi Ze for the joint. All held here.

Where is LI-12 Zhou Liao located?

LI-12 is on the outer side of the arm just above the elbow, one cun above LI-11, on the border of the upper-arm bone.

• 1 cun above (proximal to) LI-11 Qu Chi, the elbow-crease point
• On the lateral (outer) side of the upper arm, on the border of the humerus
• Best found with the elbow flexed, which brings the bony border and the point’s hollow forward

Found from LI-11, not measured from a distant landmark. The reliable way to LI-12 is to fix LI-11 Qu Chi first — the outer end of the elbow crease when the elbow is bent — then move one cun up onto the bone. The point sits in the small hollow (the “bone hole” of its name) on the ridge of the humerus above the lateral epicondyle. Bending the elbow makes both LI-11 and the ridge easy to feel.

On the name. “Zhou Liao” — Elbow Bone Hole, the hole being the hollow on the humerus the point occupies.

• A Manual of Acupuncture (p. 114): When the elbow is flexed, this point is located in the depression 1 cun proximal to and 1 cun lateral to Quchi L.I.-11.
• Chinese Acupuncture and Moxibustion (p. 142): When the elbow is flexed, the point is on the lateral side of the upper arm, 1 cun above Quchi (LI-11), on the border of humerus.

How is LI-12 Zhou Liao 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, toward the bone the point sits on.
• Moxibustion: recorded as applicable.
• Regional anatomy: the point overlies the lateral border of the humerus above the elbow, among the origins of the forearm extensor muscles; the radial nerve runs down the back of the humerus in this region, and the radial collateral vessels accompany it; bone is immediately deep.

Hazard, stated proportionately. This is a low-hazard point: no body cavity, no organ, bone immediately beneath. Our record carries no arterial caution at LI-12, and it is not among the nine points in the library that do — but its neighbour three cun higher, LI-13 Shou Wu Li, is one of the nine, and that caution belongs to LI-13, not here. The radial nerve in the region means the needling can produce a marked local sensation.

What is not claimed. No study measuring a safe depth at LI-12 could be located, and none is borrowed. No case report naming LI-12 was located.

Is there research on LI-12, and what should a reader know?

No trial isolates LI-12. Where the point appears it is one component of an elbow-pain protocol, and a study that includes a point in a protocol is not evidence about that point.

What this page can state with confidence. LI-12 Zhou Liao is a local elbow point — both its recorded actions and its single indication concern the elbow it sits beside, one cun above LI-11 on the border of the humerus. It is named, like the sacral liao and ST-03 Ju Liao, for the bone hole it occupies. It carries no five-shu element, no special classification and no arterial caution — the arterial caution nearby belongs to LI-13, three cun higher.

A note on searching for it. “LI 12”, “L 12” and “Zhouliao” searches return protocol trials and unrelated material — and “liao” points are numerous and easily confused (Zhou Liao, Ju Liao, He Liao, the sacral liao). Any claim attached to this point should be checked against which liao a study actually used.
