Where it is
Upper back, two finger-widths lateral to the spine, about level with the third thoracic vertebra, near the upper shoulder blade.
Nearby: Lung under the rib cage. Back-shu points are muscle points, not invitations to press between bones.
Traditionally said to
Back-shu of the Lung. Traditionally said to regulate lung qi, used in teaching for cough, grief, and the surface of a cold.
What people look up
Acupressure
Palm or finger on the muscle, mild, 30–45 seconds while seated and breathing easily.
When not to press: Do not press if you are wheezing badly or the spot is acutely tender after a fall.
About 30–90 seconds is the usual window, unless the step above is shorter. Stop if pain, dizziness, or anything unusual shows up.
Licensed practice only
Needle depth, angle, electroacupuncture
Textbook language for students. Not instructions. A cun is a body-inch on that person, not a ruler inch. Do not needle yourself.
Depth
Oblique toward the spine, commonly 0.5–0.8 cun. Pneumothorax risk if perpendicular and deep.
Angle
Oblique medial, 45 degrees or shallower, toward the spine.
Electroacupuncture
Introductory charts rarely assign a standard electroacupuncture setting here. Clinics that use current choose frequency and intensity for that person. No milliamp figure is given, because copying one would be misleading.
