Where it is

Two finger-widths lateral to the spine, about level with the fifth thoracic vertebra, between the shoulder blades.

Nearby: Heart and lungs lie anterior. Press muscle only.

Traditionally said to

Back-shu of the Heart. Traditional point for shen, sleep, and a restless chest in pattern language. Student texts sometimes add poor memory here. Chest pain, fainting, or a new flutter needs a clinician, not this point.

What people look up

Stress and shen Sleep Local muscle tension Memory and focus Palpitations Worry

Acupressure

Soft pressure on the muscle, 30–45 seconds, ideally while someone else is calm and not digging.

When not to press: Do not use this as care for palpitations, chest pain, or fainting.

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.

Angle

Oblique medial. Not perpendicular through the rib space.

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.
