PC-3 Quze
PC-3 Quze (曲澤) 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 elbow crease, on the ulnar side of the tendon of the biceps brachii.
How to find it
Bend the elbow. Find the central biceps tendon in the crease; the point is just on its little-finger side.
Traditional functions
- He-sea point of the Pericardium meridian
- Clears heat
- Harmonizes the stomach
Traditional uses
- Elbow discomfort
- Nausea and vomiting in traditional practice
- Chest heat
- Restlessness
How to press it
Press gently for 30–60 seconds with the elbow slightly bent.
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
Blood vessels and nerves run nearby. Avoid deep pressure; stop if you feel tingling.
How this is viewed today
PC-3 is used in clinical practice for nausea and elbow pain; research is limited.
