Where it is

On the sole, in the hollow that appears when you curl the toes, about a third of the way from the base of the toes to the heel, on the midline.

Nearby: Plantar tissue. Can feel intense. No major vessel at the surface.

Traditionally said to

Jing-well and wood point of the Kidney. Traditionally said to descend excess from the head and to calm. People press it at night when the mind is loud. Strong pressure can be too much.

What people look up

Sleep Stress and shen Headache Energy and fatigue

Acupressure

Thumb or knuckle in the hollow, moderate, 30–60 seconds, often lying down. Stop if it feels sharp or makes you dizzy.

When not to press: Skip cuts, plantar warts, or a very tender sole from injury.

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. Sensitive point; many clinicians needle less than the chart.

Angle

Perpendicular, in the depression of the sole.

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.
