SJ-08 (San Yang Luo) Three Yang Connection

What does SJ-08 San Yang Luo do?

SJ-08 clears the San Jiao channel and activates the channel to alleviate pain — a forearm point named for the meeting of the three arm yang channels.

• Clears the San Jiao channel — the channel-clearing action reaching the ear, throat and side of the body it serves
• Activates the channel and alleviates pain — the arm-and-local action

What the name means — and a distinction worth making. “San Yang Luo” means Three Yang Connection — san yang the three yang channels of the arm (Large Intestine, Small Intestine and San Jiao), luo a connection or network. The point is understood as a place where the three arm yang channels communicate, which is the classical explanation for its unusually wide reach (ear, voice, chest-and-side, teeth, arm). But this is not the Luo-Connecting point of the San Jiao — that classification belongs to SJ-05 Wai Guan, which our data marks as the Luo point. Here luo is descriptive, part of the name, not a classification. It is exactly the kind of thing a careful reader wants disambiguated.

Why the wide indications, then. A point said to connect three yang channels is reached for when disorder spans more than the San Jiao alone — and the classical texts also note San Yang Luo among the empirical points for pain, including as a distal analgesia point. That reputation, not a five-shu role (it has no element), is what gives it its place.

What is SJ-08 San Yang Luo used for?

SJ-08 is used for deafness, sudden hoarseness or loss of voice, pain in the chest and side (hypochondriac region), pain in the hand and arm, and toothache. Our own indication record is reproduced here in full.

• Deafness
• Sudden hoarseness of the voice
• Pain in the chest and hypochondriac (side/rib) region
• Pain in the hand and arm
• Toothache

A wide spread, matching a three-channel point. Ear, voice, chest-and-side, arm and teeth reach across more territory than most forearm points — consistent with a point named for the meeting of three yang channels. The hypochondriac (side) pain is the shao yang signature, shared with the Gall Bladder channel.

An honest note. Deafness of sudden onset is a medical emergency — sudden sensorineural hearing loss needs same-week specialist care. Sudden or persistent hoarseness — more than three weeks — requires assessment of the larynx. Chest pain requires assessment; cardiac and other serious causes must be excluded before it is treated as musculoskeletal. This record documents classical use only.

How it is combined. With SJ-05 Wai Guan and SJ-06 Zhi Gou on the same forearm — SJ-06 the classical point for hypochondriac pain — and with SJ-17 Yi Feng for the ear. All held here.

Where is SJ-08 San Yang Luo located?

SJ-08 is on the back of the forearm, four cun above the wrist crease, in the gap between the two forearm bones.

• 4 cun proximal to (above) the dorsal wrist crease, on the back of the forearm
• Between the radius and the ulna — in the interosseous space, the midline gap between the two forearm bones
• One cun above SJ-06 Zhi Gou (at 3 cun), which sits in the same interbone gap

Ordered with SJ-05 and SJ-06 up the back of the forearm. The dorsal San Jiao points climb the interosseous space by measurement from the wrist: SJ-05 Wai Guan at 2 cun, SJ-06 Zhi Gou at 3 cun, SJ-08 San Yang Luo at 4 cun. Finding SJ-05 or SJ-06 first and stepping up the gap between the bones is the reliable route. All three lie on the midline of the back of the forearm.

On the name. “San Yang Luo” — Three Yang Connection, the meeting of the arm’s three yang channels, as noted above.

• A Manual of Acupuncture (p. 400): 4 cun proximal to Yangchi SJ-4, in the depression between the radius and the ulna, on the radial side of the extensor digitorum communis muscle.
• Chinese Acupuncture and Moxibustion (p. 205): 4 cun proximal to the dorsal crease of the wrist, between the radius and ulna.

How is SJ-08 San Yang Luo 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, into the interosseous space between the forearm bones.
• Moxibustion: recorded as applicable.
• Regional anatomy: the point lies between the radius and ulna over the interosseous membrane, among the deep forearm extensors; the posterior interosseous nerve and vessels run in the region; the two bones flank it.

Hazard, stated proportionately. This is a low-hazard point: no body cavity, no pleura, no organ, bones flanking the needle path. Our record carries no arterial caution at SJ-08, and it is not among the nine points that do. The posterior interosseous nerve nearby can make the needling sensation carry.

A historical footnote. San Yang Luo is one of the points named in classical accounts of acupuncture analgesia. That is a historical and empirical note, not a claim that this page can substantiate a mechanism — the modern evidence for acupuncture analgesia is a separate and much-debated matter.

What is not claimed. No study measuring a safe depth at SJ-08 could be located, and none is borrowed. No case report naming SJ-08 was located.

Is there research on SJ-08, and what should a reader know?

No trial isolates SJ-08. 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.

What this page can state with confidence. SJ-08 San Yang Luo (“Three Yang Connection”) is a forearm point named for the meeting of the arm’s three yang channels, which is the classical account of its wide reach — ear, voice, chest-and-side, arm and teeth. It is not the Luo-Connecting point of the San Jiao: that classification belongs to SJ-05 Wai Guan, confirmed against our own data; the luo here is descriptive. It carries no five-shu element, and sits 4 cun above the wrist between the forearm bones.

A note on searching for it. “SJ 8”, “TE 8”, “TW 8” and “Sanyangluo” searches return protocol trials and unrelated material — and the name’s luo invites confusion with the true Luo point SJ-05. Any claim attached to this point should be checked against what a study actually used.
