Acupuncture Points on the Liver Channel of Foot Jue Yin
What does LIV-12 Ji Mai do, and why is it treated so cautiously?
LIV-12 eliminates cold from the Liver channel and benefits the lower jiao — and it is one of only two points in this library whose own record gives NO needle depth: it is treated with moxibustion, not the needle, because it sits directly over the femoral vessels at the groin.
- Eliminates cold from the Liver channel — the action behind its cold-hernia and genital-pain indications
- Benefits the lower jiao
Its name states the reason for the caution. “Ji Mai” means Urgent Pulse or Racing Pulse — ji urgent or rapid, mai a vessel or pulse. The name refers to the femoral artery’s strong pulse, palpable at exactly this point in the groin crease. When a point’s name is the pulse of a major artery, that artery is what defines it — the same relationship our ST-42 Chong Yang (Surging Yang) and ST-05 Da Ying records describe, where the name is the artery.
Our record gives no insertion, and that is the record, not a gap. The needling field holds only “moxibustion is applicable” — no angle, no depth. Querying every needling record in the library, only two points give no insertion at all: LIV-12 here and ST-17 Ru Zhong, the nipple. ST-17 is a landmark, never treated; LIV-12 is a point that IS treated, but classically with moxa or pressure rather than the needle, because the femoral artery, vein and nerve lie immediately beside and beneath it. It is the great-vessel analogue of what ST-17 is for the breast — a point where our data forecloses needling by giving none.

What is LIV-12 Ji Mai used for?
LIV-12 is used for lower abdominal pain, hernia, and pain in the external genitals. Our own indication record is reproduced here in full — three entries.
- Lower abdominal pain
- Hernia
- Pain in the external genitalia
All three are the Liver channel’s genital territory. The Liver channel encircles the external genitals in the classical anatomy — our LIV-01 record sets that out — so hernia, genital pain and lower abdominal pain are the channel’s own region, and LIV-12, in the groin crease, is a local point for them. The recorded shan (hernia) and genital indications echo LIV-01 at the other end of the channel.
An honest note, and two entries are urgent. A HERNIA THAT BECOMES PAINFUL, TENSE OR IRREDUCIBLE IS A SURGICAL EMERGENCY, and any hernia warrants assessment. ACUTE, SEVERE PAIN OR SWELLING OF THE GENITALS IS A MEDICAL EMERGENCY — in a man, sudden testicular pain can mean torsion, where the testicle can be lost within hours. Lower abdominal pain that is severe, sudden or persistent requires assessment; its causes include surgical emergencies. This record documents classical use only, and nothing here should delay any of that.
A necessary practical note. This point is in the groin, an intimate region. Any treatment here calls for the same standards of consent, draping, privacy and professional conduct that apply to any examination of the groin, and in many settings a chaperone. This record describes a location in a reference work; it is not a suggestion that a reader locate or treat this point.
How it is combined. With LIV-11 Yin Lian and LIV-10 Zu Wu Li above on the inner thigh. With REN-02 Qu Gu and REN-04 Guan Yuan on the lower abdomen, and LIV-01 Da Dun distally for the genital indications. All held here.

Where is LIV-12 Ji Mai located?
LIV-12 is in the groin crease, a little below and to the side of the pubic bone, on the inner side of where the femoral pulse is felt.
- 1 cun below and 2.5 cun lateral to REN-02 Qu Gu, on the upper border of the pubic bone
- In the crease of the groin, medial to the femoral vein — our record places it by the vessel
The femoral vessels are the location, and they are the caution. At the groin crease the femoral artery, vein and nerve pass from the abdomen into the thigh, side by side — the artery’s pulse plainly palpable. Our record places LIV-12 medial to the femoral vein, so the point is defined by its relationship to the bundle. That the vessels both fix the position and are the reason the point is not needled is the whole character of it. Our SP-12 Chong Men record sits in the same groin crease and carries an explicit “avoid puncturing the artery” caution for the same femoral artery.
On the name. “Ji Mai” — Urgent Pulse, the femoral pulse itself.

Is LIV-12 Ji Mai needled?
Our own record gives NO needle insertion — it states only that moxibustion is applicable. The point sits over the femoral vessels at the groin, and it is classically treated with moxa or pressure rather than the needle. This is a neutral record of what our data holds. There is no insertion described because our record documents none.
- No angle, no depth. Our needling field holds only “moxibustion is applicable” — the one point on the Liver channel, and one of only two in the whole library, given no insertion.
- Moxibustion: recorded as applicable, and it is the treatment of choice here, warming cold in the Liver channel without approaching the vessels with a needle.
- Regional anatomy: the femoral artery, femoral vein and femoral nerve pass through the groin crease side by side, from the abdomen into the thigh; the artery’s pulse is palpable; the great saphenous vein joins the femoral vein nearby; the inguinal lymph nodes lie in the region.
Why our record forecloses needling, stated plainly. A major artery, a major vein and a major nerve lie together immediately beside and beneath this point. That is among the most vessel-dense locations on the body, and the classical answer — reflected in our record giving no needle depth — is not to needle it. This is the great-vessel counterpart of the two other points this library treats specially: ST-17, the nipple, given no insertion because it is a landmark; and SP-12, in the same groin crease, needled only with an explicit arterial caution. LIV-12 is the one our data resolves by omitting the needle altogether.
What is not claimed. No depth, no angle, no measured margin — because our record intends none. There is nothing to measure at a point our data does not needle.

What should a reader know about LIV-12 Ji Mai?
No trial isolates LIV-12, and the question of “research on the needling” scarcely arises, because our record does not needle it. Where the point appears it is one component of a genital or hernia protocol treated with moxa.
What this page can state with confidence. LIV-12 is one of only two points in the library whose record gives no needle insertion — with ST-17, the nipple — and it is the one that is genuinely treated, classically with moxibustion, its needling foreclosed by our data because the femoral artery, vein and nerve lie immediately beside it. Its name, Urgent Pulse, is that femoral pulse. Its indications are the Liver channel’s genital and hernia territory, the same the channel carries at LIV-01. And it shares the groin crease with SP-12, which our record does needle but only with an explicit arterial caution — the two points marking the two ways this library handles a great-vessel site.
The warnings are the operative content. A painful or irreducible hernia, and acute genital pain, are emergencies.
A note on searching for it. “LIV 12”, “LR 12” and “Jimai” searches return protocol trials and unrelated material — and this channel is coded LIV, LR and Liv across the literature. Our library uses LIV-. Any claim attached to this point should be checked against what a study actually used, and against whether it needled the point at all.
