Where it is

Four finger-widths straight above the tip of the inner ankle bone, just behind the back edge of the tibia.

Nearby: The tibia is the hard landmark. The posterior tibial vessels are deeper and more posterior. Stay just behind the bone.

Traditionally said to

Meeting of the Spleen, Liver, and Kidney channels. Traditionally used for digestion, sleep, cycles, damp, and lower-abdomen patterns that textbooks group with erectile difficulty. One of the points most consistently avoided for self-care in pregnancy because it is said to move blood in the lower abdomen. Not a treatment for ED.

Acupressure

Press just behind the shin bone for 45–90 seconds. A dull ache is common.

When not to press: Do not use in pregnancy. Skip if the inner leg is swollen, hot, or tender along a vein.

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 1–1.5 cun perpendicular. Traditionally contraindicated in pregnancy in most student manuals.

Angle

Perpendicular, just posterior to the tibial border.

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.
