About Jingqu (LU8)
The name Jingqu joins jing, a channel or watercourse, with qu, a ditch or canal — the “Channel Gutter” through which the qi runs as water runs in a cut channel. The name belongs to its category: among the five-shu points, LU8 is the Jing-River point, where the qi of the channel is said to flow as a river flows, broad and moving.
Its five-phase assignment is unusually fitting. LU8 is the Metal point of the Lung, and the Lung is itself the Metal organ — so this is the point where the channel’s own phase is doubled, its “horary” point. In the classical scheme this makes it a place where the Lung’s essential, metallic, descending quality is most concentrated along the river of the channel.
Set just above the wrist beside the radial artery, it is bracketed by two of the channel’s great points — Lieque just proximal and Taiyuan just distal — and is used more sparingly than either, hedged in the classics by the caution against moxibustion. It is, in the geography of the Hand Taiyin line, the steady river-stretch between the wrist’s crossroads and its source.
Jing-River point; Metal point of the Lung · Five-phase: Metal (Jing-River)
What are the functions of Jingqu in TCM?
In TCM this point is classically described as descending and regulating Lung qi and easing cough and wheeze. As the Jing-River and Metal point — the phase that matches the channel itself — it is associated with the smooth flowing of qi along the channel and with disorders of the voice and throat.
What is Jingqu classically indicated for?
Classically indicated for cough and asthma, fullness of the chest, sore throat and hoarse voice, and pain at the wrist. Classical texts note it as a point used with some restraint, often without moxibustion.
Where is Jingqu located?
The WHO Standard Acupuncture Point Locations places LU8 on the anterolateral aspect of the forearm, 1 cun proximal to the wrist crease, in the depression between the styloid process of the radius and the radial artery, on the line connecting LU9 Taiyuan and LU6 Kongzui.
Lies in the depression at the base of the styloid process of the radius, just radial to the radial artery; the superficial radial nerve runs nearby.
Needling reference
Educational reference only — describing how classical and standard texts characterize this point, not clinical instruction.
Standard references describe shallow perpendicular insertion to roughly 0.2–0.3 cun, carefully avoiding the adjacent radial artery. The classical literature commonly advises against moxibustion at this point. No pneumothorax caution applies.
What are the cautions for Jingqu?
No pneumothorax risk. The radial artery lies immediately beside the point, so standard references advise shallow needling that avoids the vessel; classical sources caution against moxibustion here.
