Large Intestine channel · point 6
Traditionally used for
- Ears & hearing
- Nose & throat
- Urinary & fluids
Location
On the posterolateral aspect of the forearm, on the line connecting LI5 and LI11, 3 cun proximal to the dorsal wrist crease — the junction of the lower quarter and upper three-quarters of that line.
How to locate: With the elbow flexed and the forearm in mid-position, measure 3 cun (one hand-breadth) up from LI5 in the anatomical snuffbox along the line to LI11. Alternatively, cross the thumb webs of both hands with one index finger on the opposite radial styloid and lay the middle finger beside it: the middle fingertip falls on the point.
Distances are in cun, a proportional unit — how to measure.
