LI-10 - Arm Three Miles
手三里 - Shǒu sān lǐ
Point Region: Forearm
Location & How to Find
Anatomical Location: On the back and thumb side of the forearm, on the line from LI-5 at the wrist to LI-11 at the elbow, 2 cun below the elbow crease.
Distances are in cun, a unit that scales with each person's body. As a guide, the width of your thumb at its joint is 1 cun, and your four fingers held together, measured across the middle joints, are 3 cun.
How to Locate:
- Find LI-11 at the outer end of the elbow crease
- Measure two thumb-widths down the line toward the wrist
- The point is on that line
How to Apply Pressure
Bend the elbow and find the spot two thumb-widths below the elbow crease on the thumb side of the forearm. Press into the muscle with the thumb, firm but never painful. Skip it after arm surgery, and black or bloody stools need medical care.
