Where it is
On the index finger, beside the nail corner on the thumb side.
Nearby: Fingertip. Little padding.
Traditionally said to
Jing-well and metal point of Large Intestine. Classically for clearing heat at the start of the channel, including tooth or throat heat in teaching cases.
What people look up
Acupressure
Light pressure beside the nail for 20–30 seconds only.
When not to press: Do not bleed the fingertip. Skip broken skin.
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
Often listed around 0.1 cun, sometimes as a prick. Not for self-needling.
Angle
Shallow, beside the nail.
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.
