Where it is

At the inner end of the elbow crease, when the elbow is bent, just in front of the inner bony knob.

Nearby: The ulnar nerve (“funny bone”) runs behind the inner elbow. Stay in the crease, not behind the bone.

Traditionally said to

He-sea and water point of the Heart. Taught for heart-channel pain, calm, and local elbow tension. Shen language here is traditional, not a psychiatric claim.

What people look up

Stress and shen Local muscle tension Pain relief

Acupressure

Elbow softly bent, press the inner crease for 30–45 seconds. Stop at any electric zing into the little finger.

When not to press: Do not chase a tingling nerve. That is the ulnar nerve, not the point.

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

Common textbook range: about 0.5–1 cun perpendicular.

Angle

Perpendicular, in the crease, anterior to the medial epicondyle.

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.
