Where it is

On the inner thigh, about two thumb-widths above the upper inner corner of the kneecap, in the bulge of the vastus medialis. A palm on the kneecap often puts the thumb near it.

Nearby: Thigh muscle. Large, forgiving tissue if you stay off a painful vein.

Traditionally said to

Named for blood. Traditionally said to move and cool blood, and used in teaching for cycle discomfort and certain skin patterns. Not a blood thinner and not a fertility method.

What people look up

Women’s health Pain relief Local muscle tension

Acupressure

Seated, press the inner thigh muscle above the knee for 45–60 seconds.

When not to press: Skip varicose veins, a bruise, or pregnancy self-treatment aimed at the cycle.

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.

Angle

Perpendicular, into vastus medialis.

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.
