About Kongzui (LU6)
The name Kongzui joins kong, an opening or hole, with zui, “greatest” or “most” — the “greatest opening,” the cleft where the channel’s qi gathers most fully. The name announces its category directly: LU6 is the Xi-Cleft point of the Lung.
Xi-Cleft points are the places where the qi and blood of a channel are said to pool and concentrate, and classical doctrine reaches for them in acute, intense, and often blood-involving disorders. On the Lung channel this gives LU6 its characteristic reputation — the point turned to for a sudden attack of cough or wheeze, and for bleeding that rises with the Lung’s rebellious qi, such as the coughing of blood.
Set midway down the forearm on the line between the elbow’s Chize and the wrist’s Taiyuan, it is the channel’s reservoir of concentrated qi. Where LU5 cools and LU9 tonifies, LU6 is the point classically associated with the acute moment — the cleft that holds the channel’s reserve.
Xi-Cleft (accumulation) point of the Lung
What are the functions of Kongzui in TCM?
In TCM this point is classically described as the Xi-Cleft point where Lung qi accumulates; it is used to clear Lung heat, descend rebellious qi for acute cough and asthma, stop bleeding (especially coughing or spitting of blood), and ease the throat.
What is Kongzui classically indicated for?
Classically indicated for acute cough and asthma attacks, coughing of blood and nosebleed, sore throat with loss of voice, hemorrhoidal bleeding, and pain of the forearm and elbow. As a Xi-Cleft point it is traditionally associated with acute and painful, blood-related Lung patterns.
Where is Kongzui located?
The WHO Standard Acupuncture Point Locations places LU6 on the anterolateral aspect of the forearm, on the line connecting LU5 Chize and LU9 Taiyuan, 7 cun proximal to the wrist crease (LU9).
Lies on the radial-palmar aspect of the forearm over the brachioradialis and flexor carpi radialis, near the radial artery and the superficial branch of the radial nerve.
Needling reference
Educational reference only — describing how classical and standard texts characterize this point, not clinical instruction.
Standard references describe perpendicular insertion to roughly 0.5–1.0 cun. The point is on the forearm, away from the chest, so no pneumothorax caution applies.
What are the cautions for Kongzui?
No pneumothorax risk. General forearm needling cautions apply.
