LI4 (Union Valley) Acupoint — Complete Guide to Accurate Location and Acupressure Technique

What is Hegu?

Hegu (Union Valley) is an acupoint belonging to the Large Intestine meridian and is one of the most widely used acupoints in traditional Chinese medicine. Located on the hand with excellent accessibility, it can be easily stimulated anytime and anywhere. Because it works quickly and effectively for various symptoms, it’s known as a “universal acupoint.”

How to Find the Exact Location

Step 1: Open your hand and spread your thumb and index finger apart.
Step 2: Find the most depressed area between the two fingers.
Step 3: It’s located at the midpoint of the index finger bone (second metacarpal) and slightly below the end of the thumb bone (first metacarpal).
Step 4: When you press this area, you’ll feel slight tenderness—this is the Hegu acupoint.

Acupressure Method

1. Basic Acupressure Technique: Using the opposite thumb, press the Hegu acupoint vertically. Press firmly enough to feel some tenderness, hold for 3-5 seconds, then slowly release.

2. Rotational Acupressure Technique: While pressing Hegu with your thumb, make small circular motions—rotate clockwise 10 times, then counterclockwise 10 times.

3. Duration: Apply acupressure for about 5-10 minutes per session, up to 2-3 times per day. When symptoms are acute, stimulating several times at 1-2 minute intervals is also effective.

When is the Best Time to Apply Acupressure?

Optimal Timing: Applying acupressure immediately when symptoms appear is most effective. Quick pressure when headaches or toothaches suddenly occur, or at the first sign of cold symptoms, helps prevent symptom worsening.

Preventive Acupressure: Stimulating the point 1-2 times daily during periods of high stress or during cold season can help prevent symptoms from developing.

No Time Restrictions: You can apply acupressure anytime, though it’s better to do so 30 minutes after eating.

Precautions

Pregnancy Precautions: It’s best to avoid Hegu acupressure during pregnancy as it may trigger contractions. Consult with a healthcare professional.

Avoid Excessive Pressure: While some tenderness is fine, avoid pressing too hard or causing injury.

Emergency Situations: If acute illness or severe pain persists, seek professional medical care. Hegu acupressure is not emergency medicine.

Consider Individual Differences: Effects may vary depending on individual constitution and symptom severity.
