A quieter but capable point on the Large Intestine channel (LI), Xialian (LI-8) sits on the forearm and specialises in regulating Qi and Blood (Xue) in the arm and channel, easing abdominal discomfort, and settling wind-related symptoms in the head.
Contraindications
LI-8 is a safe forearm point with no special contraindications. Use standard clean needling technique and stay within the recommended depth.
Name & story
The name 下廉 Xialian means "Lower Ridge" or "Lower Angle" — 廉 (lián) refers to a corner, edge or ridge, and 下 (xia) simply means lower. The point sits on the forearm along the ridge-like bony edge of the radius, the lower of two points sharing this ridge name (its neighbour above is Shanglian LI-9, the "Upper Ridge"). The name is quietly geographic — a pointer to where the point lives on the arm, tucked along the lower edge of that bony line.
Point family & character
LI-8 belongs to the Large Intestine channel (LI). It does not carry a major classical category such as Yuan Source or He-Sea, but it is a recognised local and channel point of the forearm, used both for arm and channel disorders and for its ability to reach the abdomen through the course of the channel.
Five-element dynamics
The Large Intestine channel is a Metal channel, paired with the Lung. Metal governs letting go, descending and clearing — and the Large Intestine is the organ that embodies this most literally, moving things downward and out. Xialian (LI-8) shares this descending, clearing character: it helps Qi move smoothly through the arm and supports the channel's natural direction downward, easing both local stagnation and abdominal discomfort that arises when that flow is interrupted.
Location
On the radial (thumb) side of the forearm, 4 Cun below LI-11 (Quchi), along the line running from LI-11 toward the wrist. It is 1 Cun below its neighbour Shanglian LI-9.
Anatomy & fascia
The point lies on the forearm, in the muscle belly of the extensor digitorum communis and near the extensor carpi radialis brevis, along the radial side of the forearm.
Needling
The needle is inserted perpendicularly (straight in).
Safe depth
0.8–1.2 Cun.
Moxa, cupping & Tui Na
Massage and acupressure along the forearm channel can complement needling, helping to move Qi and Blood (Xue) through the arm. Moxa may be applied when Cold or deficiency underlies the presentation.
Functions
Regulates Qi and Blood (Xue) in the arm and channel; opens and clears the Large Intestine channel. Regulates the intestines and relieves abdominal pain. Clears Wind and Heat from the head.
Indications
Pain, weakness or numbness in the arm and elbow; local forearm and channel disorders. Abdominal pain and rumbling in the intestines. Headache and dizziness. Eye pain. Breast conditions.
Point combinations
With LI-9 (Shanglian) — for forearm and channel disorders, as the two ridge points work closely together. With LI-11 (Quchi) — to clear Heat and regulate the arm channel.
Clinical spotlight
Xialian (LI-8) is one of the forearm points of the Large Intestine channel (LI) that bridges local arm treatment with abdominal regulation — a reminder that in Chinese medicine, a point on the arm can speak directly to the belly through the channel's deep connections. Its name, "Lower Ridge", anchors it in a pair with Shanglian LI-9 above it, and together these two points form a useful local team for forearm and elbow problems.
The golden tip
To find LI-8, lay your arm palm-down and measure about 4 Cun (roughly a hand's width) below the elbow crease, along the thumb-side edge of the forearm. Firm acupressure here for 1–2 minutes can help ease forearm tension or mild arm fatigue. For Cold or stiffness, a warm compress over the area is a gentle complement.
