LI-4 Hegu
LI-4 Hegu (合谷) is a point on the Large Intestine 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 hand, between the first and second metacarpal bones, at the midpoint of the second metacarpal.
How to find it
Bring the thumb and index finger together. The point is at the highest point of the muscle bulge between them, slightly toward the index finger.
Traditional functions
- Yuan-source point of the Large Intestine meridian
- Opens the exterior and releases the surface
- Moves qi and blood; benefits the face, head, and mouth
Traditional uses
- Head, face, and neck discomfort
- Toothache and jaw tension
- Nasal congestion
- Stress and tension held in the hands
How to press it
Pinch the point between the thumb and index finger of the other hand for 1–2 minutes. Switch hands. It is often quite tender — ease off if the sensation is sharp.
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
Strong pressure at LI-4 is traditionally avoided during pregnancy. Do not press over infected or broken skin.
How this is viewed today
LI-4 is one of the most studied acupuncture points, appearing in trials for headache, dental pain, and pain generally. Systematic reviews often report short-term benefit with low certainty.
