PC-7 Daling
PC-7 Daling (大陵) is a point on the Pericardium 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
At the middle of the wrist crease, between the tendons of palmaris longus and flexor carpi radialis.
How to find it
Lay the palm face up. The point is in the center of the wrist crease, between the two prominent tendons.
Traditional functions
- Shu-stream and yuan-source point of the Pericardium
- Calms the spirit and clears heart heat
- Benefits the wrist
Traditional uses
- Wrist pain
- Restlessness and mouth ulcers in traditional practice
- Palpitations
- Anxiety
How to press it
Press gently for 1 minute. Avoid pressing directly on the median nerve if you feel tingling.
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
Stop if pressure causes numbness or tingling in the hand.
How this is viewed today
PC-7 is used in trials for wrist pain and carpal tunnel symptoms. Evidence is limited.
