Where it is
Just below the outer ankle bone, in the hollow before the tendon that runs to the little toe.
Nearby: Outer ankle ligaments. A small hollow. Don’t grind a sprained ankle.
Traditionally said to
Opening point of the Yang Qiao vessel. Studied with SI3. Traditional notes mention daytime epilepsy patterns and a stiff lateral body — historical categories, not seizure first aid.
What people look up
Acupressure
Light pressure in the hollow, 20–40 seconds.
When not to press: Do not press a sprained, swollen ankle. Seizure care is medical care.
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 0.3–0.5 cun perpendicular.
Angle
Perpendicular, below the lateral malleolus.
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.
