Where it is

On the inner forearm, three finger-widths up from the wrist crease, between the two central tendons.

Nearby: The median nerve runs between those tendons. Pressure should ache a little, not send sparks into the fingers.

Traditionally said to

Luo point of the Pericardium and opening point of the Yin Wei vessel. The point most often taught for nausea, chest tightness, and a restless spirit. Travel bands sit here for a reason — they are still not medical devices in this app.

What people look up

Nausea Stress and shen Digestion Sleep Worry Palpitations

Acupressure

Press between the tendons, straight down, for 45–90 seconds. Both arms if you like. Ease off the moment the fingers tingle.

When not to press: Stop if the hand goes numb. Do not use a hard object. Chest pain or vomiting with other worrying signs needs care, not a point.

About 30–90 seconds is the usual window, unless the step above is shorter. Stop if pain, dizziness, or anything unusual shows up.

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, sometimes listed to 1.5 in a larger forearm. The median nerve is the limit.

Angle

Perpendicular, between the tendons.

Electroacupuncture

Nausea research has often used PC6, sometimes with gentle electrical stimulation reported around 10–25 Hz in supervised trials. Devices, side of the body, and intensity were chosen by clinicians. Do not improvise a device. No milliamp dose is listed.
