TB-4 Yangchi
TB-4 Yangchi (陽池) is a point on the Triple Burner meridian. In TCM theory it is described as influencing the channel's qi, and it is traditionally used in the context of the whole pattern rather than as a stand-alone remedy. This page explains how to locate it, what the tradition says about it, and how to press it safely.
Location
On the dorsum of the wrist, in the depression at the level of the wrist crease, ulnar to the extensor tendons.
How to find it
Turn the palm down. The point is in the hollow at the center of the back of the wrist crease.
Traditional functions
- Yuan-source point of the Triple Burner meridian
- Benefits the wrist
- Regulates fluids
Traditional uses
- Wrist pain
- Dry mouth
- Edema in traditional practice
- Hand fatigue
How to press it
Press gently for 1 minute, then move the wrist through a small range.
Acupressure is generally a gentle practice. Use the pad of the thumb or finger, start with light pressure, and increase only to a comfortable level. A mild ache or warmth is common; sharp pain is a signal to ease off.
Safety
Avoid strong pressure over an injured wrist.
How this is viewed today
