BL-63 (Jin Men) Metal Gate

What does BL-63 Jin Men do?

BL-63 is the Xi-Cleft point of the Bladder channel — and unusually, our own record states the Xi-Cleft function directly in its action field: it MODERATES ACUTE CONDITIONS. Most records leave that to be inferred from the classification. Here it is written out.

• Moderates acute conditions — the Xi-Cleft function itself
• Pacifies wind — the action the convulsion and epilepsy indications rest on
• Relaxes the sinews, activates the channel and alleviates pain — the channel action

What a Xi-Cleft point is for. Each regular channel has one, described as a place where qi and blood gather deeply, and the classical use is acute and painful conditions of that channel or organ — the opposite emphasis to points chosen for chronic patterns. Querying our own category fields returns twelve, one per regular channel: LU-06, LI-07, ST-34, SP-08, HT-06, SI-06, BL-63, KI-05, P-04, SJ-07, GB-36 and LIV-06. A complete set — and the classical count actually runs to sixteen, adding one for each of four extraordinary vessels, all four of which our data also holds: BL-59 for the Yang Motility, KI-08 for the Yin Motility, GB-35 for the Yang Linking and KI-09 for the Yin Linking. Sixteen present, none missing, none spare.

A refinement this library has tested rather than repeated. The commonly stated rule is that the Xi-Cleft points of yin channels additionally treat bleeding. Checking that against our own indication records, it held for eleven of twelve — SP-08’s recorded indications are irregular menstruation and dysmenorrhoea rather than bleeding explicitly. BL-63 sits on a yang channel, so the bleeding half of the rule does not apply to it, and its recorded indications are acute and musculoskeletal exactly as the pattern predicts.

It also carries a second classification: Meeting Point of the Bladder Channel with the Yang Linking Vessel (Yang Wei Mai), one of the eight extraordinary vessels.

What is BL-63 Jin Men used for?

BL-63 is used for mania, epilepsy and infantile convulsions, and for backache, outer-ankle pain and impaired movement of the leg. Our own indication record is reproduced here in full.

• Mania
• Epilepsy
• Infantile convulsion
• Backache
• Pain in the external malleolus (outer ankle bone)
• Motor impairment and pain of the lower extremities

The list splits cleanly in two, and both halves are Xi-Cleft-consistent. The convulsive group — epilepsy, infantile convulsion, mania — is acute by nature and follows the recorded wind-pacifying action. The musculoskeletal group is acute channel pain along the Bladder channel, from the back down to the outer ankle where the point sits. A Xi-Cleft point’s classical indication is precisely acute and painful presentations, and this record reads as a textbook case of that.

An honest note, and it is the most important passage on this page. Epilepsy, seizures and convulsions in a child are medical emergencies and require immediate medical care. A first seizure, a prolonged seizure, or one in an infant needs emergency assessment without delay. Epilepsy requires medical diagnosis and prescribed management, and nothing here should displace it. Mania requires medical diagnosis, and the term reflects a classical category rather than a modern one. This record documents historical use only; it makes no claim that any of these conditions is treated by acupuncture.

How it is combined. With BL-62 Shen Mai, the Confluent point of the Yang Qiao Mai, and BL-60 Kun Lun at the ankle. With BL-64 Jing Gu, the Yuan-Source point, and BL-65 Shu Gu along the same bone. With SJ-05 Wai Guan, the Confluent point of the Yang Wei Mai, given BL-63’s own Yang Wei classification. All held here.

Where is BL-63 Jin Men located?

BL-63 is on the outer edge of the foot, in the hollow just behind the bony bump at the base of the fifth metatarsal — the prominence you can feel halfway along the outer border.

• Posterior to the tuberosity of the fifth metatarsal, on the lateral side of the foot
• BL-64 Jing Gu, the Yuan-Source point, sits below and in front of the same tuberosity
• BL-62 Shen Mai lies above, below the outer ankle bone; BL-65 and BL-66 lie further forward along the same bone

The tuberosity is one of the best landmarks in the foot. It is a distinct, easily palpable prominence, and three of these points are defined in relation to it — BL-63 behind it, BL-64 below and in front of it, BL-65 at the far end of the same bone. That density is why this library repeats the same caution across all four: they carry different classifications, so mistaking one for a neighbour substitutes a category, not just a location.

On the name. “Jin Men” means Metal Gate or Golden Gate — jin being both the metal element and gold. The reading usually offered ties it to the point’s importance rather than to anything anatomical, a gate being an opening of consequence. Note that jin here is not the same character as the jin meaning sinews, despite the recorded sinew-relaxing action making that an inviting connection — our BL-56 Cheng Jin (Sinew Support) carries that other character.

• A Manual of Acupuncture (p. 322): On the lateral side of the foot, in the depression posterior to the tuberosity of the fifth metatarsal bone.
• Chinese Acupuncture and Moxibustion (p. 190): On the lateral side of the foot, directly below the anterior border of the external malleolus, on the lower border of the cuboid bone.

How is BL-63 Jin Men needled?

The standard texts record perpendicular insertion to roughly 0.3–0.5 inch, with moxibustion applicable. What follows is a neutral record of what the reference literature documents, not instruction for a reader.

• Angle and depth as recorded: perpendicular, 0.3–0.5 inch.
• Moxibustion: recorded as applicable.
• Regional anatomy: abductor digiti minimi runs along the lateral border of the foot; branches of the lateral plantar nerve and artery supply the region; the tuberosity of the fifth metatarsal and the cuboid lie deep, and the peroneus brevis tendon inserts on the tuberosity itself.

Hazard, stated proportionately. This is a low-hazard point: no body cavity, no major vessel, no large nerve trunk, and bone close beneath. The lateral border of the foot is thinly covered, which is a matter of sensation rather than danger.

What is not claimed. No study measuring a safe depth at BL-63 could be located, and none is borrowed. The paediatric chest-CT study this library uses for measured depths covers 23 named points on the trunk and shoulder and does not reach the foot. No case report naming BL-63 was located, and none is asserted.

Is there research on BL-63, and what should a reader know?

No trial isolates BL-63. Where the point appears it is one component of a protocol, and a study that includes a point in a protocol is not evidence about that point. No claim is made here that acupuncture treats epilepsy, despite epilepsy appearing in the classical indication list — that list records historical use, not evidence.

What this page can state with confidence. BL-63 is the Xi-Cleft point of the Bladder channel, and it is the clearest case in this library of a record whose action field states the Xi-Cleft function outright — “moderates acute conditions”. Its indications split into an acute convulsive group and an acute musculoskeletal group, exactly as the classification predicts. The complete set is present in our records — twelve for the regular channels, and sixteen counting the four extraordinary-vessel Xi-Cleft points (BL-59, KI-08, GB-35, KI-09) our data also holds. And the commonly repeated refinement that yin-channel Xi-Cleft points also treat bleeding was tested against our own data and held eleven of twelve, not twelve — a distinction this library reports rather than rounds off.

A note on searching for it. “BL 63”, “UB 63” and “Jinmen” searches return protocol trials and a large volume of unrelated material — Jinmen matches place names, including an island, and is a common element in business names. Our library codes this channel BL- while some sources use UB-. Any claim attached to this point should be checked against what a study actually used.
