ST-05 (Da Ying) Great Reception

What does ST-05 Da Ying do?

ST-05 eliminates wind and reduces swelling — a single recorded action, and the swelling clause is what its whole indication list turns on.

• Eliminates wind and reduces swelling — the whole of the recorded action

Its record holds no category at all, which sets it apart from its neighbours: ST-03 is a meeting point with the Yang Motility Vessel and ST-04 a meeting point of four pathways. ST-05 carries none. Where our data holds nothing, this page says so rather than supplying a classification.

“Reduces swelling” is the operative half. Three of its five indications are swelling or its consequences — cheek swelling, facial pain, toothache — and the point sits directly over the region where dental and salivary swelling appears. The action and the indications agree entirely here, which several records in this library do not; our GB-17 record documents the eighth case where they do not.

On the name. “Da Ying” means Great Reception, sometimes rendered Great Welcome. Ying, to receive or welcome, is the same character as in ST-09 Ren Ying on the neck — and both points sit beside a palpable artery, which is very likely the sense: the pulse is what is “received” under the finger. Our ST-42 Chong Yang record documents the same naming logic, where Surging Yang describes the dorsalis pedis pulse.

What is ST-05 Da Ying used for?

ST-05 is used for facial paralysis, lockjaw, swelling of the cheek, pain in the face and toothache. Our own indication record is reproduced here in full — five entries.

• Facial paralysis
• Trismus (lockjaw)
• Swelling of the cheek
• Pain in the face
• Toothache

An honest note, and three of these need one stated plainly.

• FACIAL PARALYSIS REQUIRES URGENT MEDICAL ASSESSMENT. A new facial droop can be a sign of stroke — a medical emergency where treatment given quickly changes outcomes — or Bell’s palsy, where early treatment improves recovery. Either way it needs same-day care, and facial droop with weakness elsewhere, difficulty speaking or sudden visual loss is an emergency. This record makes no claim that acupuncture treats stroke or its consequences.
• TRISMUS — “LOCKJAW” — IS AN AMBIGUOUS WORD. Difficulty opening the jaw is usually a problem of the jaw joint, its muscles, or a dental infection. But “lockjaw” is also the common name for TETANUS, a life-threatening infection preventable by vaccination. Jaw stiffness with muscle spasms, difficulty swallowing, or following a wound is a medical emergency. Our SJ-22 and GB-07 records carry the same warning for the same word.
• CHEEK SWELLING WITH FEVER OR SPREADING REDNESS NEEDS PROMPT CARE. A dental infection can spread dangerously in this region, and swelling in front of the ear can be salivary-gland disease — our SJ-20 record sets out the parotid causes. Persistent facial pain, and toothache, need assessment rather than repeated self-treatment.

Why the jaw, at this point. ST-05 sits at the anterior border of the masseter — the main chewing muscle, which can be felt to bulge when the teeth are clenched. Trismus, cheek swelling and toothache are all conditions of that immediate region, and the indication list follows the position rather than any channel argument.

How it is combined. With ST-06 Jia Che in the belly of the same muscle and ST-07 Xia Guan at the jaw joint above. With ST-04 Di Cang at the corner of the mouth — our ST-04 record documents the classical through-needling between ST-04 and ST-06. With LI-04 He Gu distally, the classical distal point for the face and teeth. All held here.

Where is ST-05 Da Ying located?

ST-05 is on the jaw, just in front of the angle of the mandible, at the front edge of the chewing muscle — where the facial artery can be felt.

• Directly anterior to the angle of the jaw
• In a depression at the anterior border of the masseter muscle — which appears when the teeth are clenched and released
• ST-06 Jia Che lies behind it in the muscle’s belly; ST-04 Di Cang forward at the corner of the mouth

Clenching the teeth is what makes this point findable. The masseter bulges when the jaw is clenched and its front edge becomes definite; the depression is felt with the muscle relaxed again. Several records in this library specify a movement or posture as part of a location — our ST-02 record requires the eyes looking straight ahead, SJ-11 the elbow flexed, SJ-20 the ear folded forward.

And the artery is here too, which is the whole character of the point. The facial artery crosses the lower border of the mandible at the anterior edge of the masseter — precisely the landmark our record names — and the pulse is palpable there. So the vessel is part of how the point is found and is what its needling record warns about. This library has documented four such cases: ST-42 with the dorsalis pedis, LU-09 with the radial artery, SJ-22 with the superficial temporal, and ST-05 here.

On the name. “Da Ying” — Great Reception. As noted above, the ying it shares with ST-09 Ren Ying very likely refers to a pulse received under the finger, and both points sit beside one.

• A Manual of Acupuncture (p. 133): Directly anterior to the angle of the jaw, in a depression at the anterior border of the masseter muscle.
• Chinese Acupuncture and Moxibustion (p. 146): Anterior to the angle of mandible, on the anterior border of the attached portion of m. masseter where the pulsation of facial artery is palpable, in the groove-like depression appearing when the cheek is bulged.

How is ST-05 Da Ying needled, and what does our record warn about?

Our own record OPENS with the caution — “AVOID PUNCTURING THE ARTERY” — before it gives any angle or depth. That ordering is retained here because it reflects what matters at this point. Oblique insertion of 0.3–0.5 inch is then recorded, 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.

• Our record states first: avoid puncturing the artery. The facial artery crosses the lower border of the mandible at the anterior border of the masseter — the exact landmark our location record uses to find this point.
• Angle and depth as recorded: oblique, 0.3–0.5 inch.
• Moxibustion: recorded as applicable.
• Regional anatomy: the facial artery and vein cross the mandible here; the masseter lies immediately behind and the buccinator in front; the marginal mandibular branch of the facial nerve runs along the jaw line in this region, and the submandibular gland lies below and deep.

Nine points in this library carry an explicit arterial caution, and ST-05 is one of them. Counted by querying every needling record: ST-05 (facial artery), ST-09 Ren Ying (common carotid), ST-42 Chong Yang (dorsalis pedis), SP-12 Chong Men (femoral), SJ-22 He Liao (superficial temporal), HT-01 Ji Quan (axillary), and LU-08 Jing Qu and LU-09 Tai Yuan (radial), with LI-13 Shou Wu Li (avoid injuring the artery). In five of the nine the pulse is also how the point is located — ST-05, ST-42, LU-09 and SJ-22 — so the landmark and the hazard are literally the same structure.

The caution stops where our data stops. Our ST-04 and ST-06 records, a short distance either side, carry no arterial caution, and this page does not export one to them — though the facial artery’s course through the region is stated on ST-04’s page because the anatomy is true regardless of where the warning sits.

Hazard, stated proportionately. There is no body cavity here and no organ within reach. The named risk is the vessel, and the recorded depth of three to five tenths of an inch and the oblique angle are what address it. The face is vascular and bruises readily — a cosmetic consideration worth knowing before treatment.

What is not claimed. No study measuring a safe depth at ST-05 could be located, and none is borrowed. Neither measured-depth study this library uses reaches the face. No case report naming ST-05 was located.

Is there research on ST-05, and what should a reader know?

No trial isolates ST-05. Where the point appears it is one component of a facial-paralysis or dental protocol, and a study that includes a point in a protocol is not evidence about that point.

Facial paralysis has one of the larger acupuncture trial literatures, and the facial Stomach points appear throughout it. Our ST-06 record cites a data-mining analysis of 1,695 studies in which ST-04 and GB-14 emerged as a top point pair — prescribing-frequency evidence, describing what practitioners choose rather than what a point does. Nothing from that literature is claimed here, and the urgent-assessment warning above is the operative content.

What this page can state with confidence. ST-05 is one of nine points in this library whose record carries an explicit arterial caution, and its record puts that caution before the depth — an ordering kept here. The facial artery is both how the point is located and what the caution names, which makes it the fourth such case documented alongside ST-42, LU-09 and SJ-22. Its record holds no category at all, unlike both its neighbours. And its action and indications agree entirely, which several records in this library do not.

Two warnings bear repeating. A new facial droop needs same-day assessment, and “lockjaw” is also the common name for tetanus — jaw stiffness with spasms or following a wound is an emergency.

A note on searching for it. “ST 5”, “S 5” and “Daying” searches return protocol trials and a very large volume of unrelated material — “Daying” matches place names, personal names and ordinary vocabulary, and in English it reads as an entirely different word. This is among the poorest search terms on the channel. Any claim attached to this point should be checked against what a study actually used.
