Bladder channel · point 37
Traditionally used for
- Nerves & recovery
- Pain & joints
Location
On the back of the thigh, 6 cun below BL36, between the biceps femoris and semitendinosus muscles, on the line connecting BL36 and BL40.
How to locate: With the patient prone, find BL36 at the centre of the gluteal fold and BL40 at the centre of the popliteal crease; the point is 6 cun below BL36, 1 cun above the midpoint of that line. Flexing the knee against resistance shows the gap between the biceps femoris and semitendinosus, where the point lies.
Distances are in cun, a proportional unit — how to measure.
