Overview

LI-4 (Hegu, 合谷) — meaning “Joining Valley” — is one of the most well-known and versatile points in Traditional Chinese Medicine (TCM). Located on the hand, this point belongs to the Large Intestine meridian, which runs along the arm and connects to the head and face.

Often called “The Master Point for the Face and Head”, LI-4 is used to support overall well-being, relieve pain, and promote the smooth flow of Qi throughout the body.

​

Location

LI-4 is found on the dorsum (back) of the hand, between the first and second metacarpal bones — in the web between the thumb and index finger.
To locate it:

  1. Bring your thumb and index finger close together.

  2. The highest point of the bulge (muscle mound) that appears is where LI-4 is located.

  3. Press gently but firmly — you may feel a mild ache or soreness.

⚠️ Caution: Do not use LI-4 during pregnancy, as it can stimulate uterine contractions.

​

Functions in TCM

According to classical TCM theory, LI-4 helps to:

  • Disperse wind and release the exterior — used for common colds, headaches, and nasal congestion.

  • Activate Qi and blood circulation — relieving pain throughout the body.

  • Clear heat and regulate the face — supporting conditions such as toothache, eye redness, or facial swelling.

  • Calm the spirit and regulate the whole body’s Qi — promoting emotional balance and relaxation.

 

Common Uses

  • Headaches and migraines

  • Facial pain, sinus issues, or toothache

  • Neck and shoulder tension

  • Stress, anxiety, or insomnia

  • Boosting immunity and energy

In cosmetic acupuncture and facial acupressure, LI-4 is often paired with ST-36 and LI-11 to enhance circulation and support skin vitality.

​

How to Apply Acupressure

  1. Use your opposite thumb to press on LI-4 in a slow, circular motion.

  2. Apply firm but comfortable pressure for 1–2 minutes on each hand.

  3. Take slow, deep breaths as you hold the point.

  4. Repeat once or twice daily, or as part of your self-care routine.

 

Integrative Perspective

Modern research suggests that stimulating LI-4 may influence the autonomic nervous system, promoting relaxation and pain modulation. Studies using fMRI have shown activity changes in brain regions associated with pain control and stress regulation when LI-4 is stimulated12.

​

Practical Tip

Combine LI-4 acupressure with gentle neck stretches or breathing exercises to release upper-body tension — perfect for those spending long hours at a computer.
