LI3 (Third Interval) Acupoint — Complete Guide to Precise Location and Acupressure Technique

What is LI3?

LI3 (Three Intervals) is an acupoint belonging to the Large Intestine meridian, located in the second metacarpophalangeal joint area of the finger. This acupoint is known to effectively relieve pain in the face and neck area, and is an important acupoint that has been used for a long time in traditional Chinese medicine. In particular, it is characterized by a quick response to acute pain, serving a role similar to first aid.

How to Find the Exact Location

Step 1: Extend your hand comfortably and look at your index finger.
Step 2: Find the second joint (second metacarpophalangeal joint) of your index finger. This is the area where wrinkles form when you bend and straighten your finger.
Step 3: Press the indented area (hollow section) on the thumb side (radial side, toward the thumb) of that wrinkle.
Step 4: When you find the correct location, you should feel slight pain or a refreshing sensation.

Acupressure Method

Basic Acupressure Technique:
1. Prepare by sitting or lying down in a comfortable position.
2. Use the side of your thumb nail or an acupressure tool.
3. Apply slight pressure perpendicular to the LI3 acupoint.
4. Press for 3-5 seconds, then slowly release the pressure.
5. Repeat this 10 times.
Tips to Enhance Effectiveness: It is more effective to perform acupressure while breathing deeply. It is fine to apply acupressure frequently when pain is severe.

When is it Good to Apply Acupressure?

Recommended in These Situations: While waiting for treatment, sudden toothache, sore throat, eye fatigue from prolonged screen work, and when experiencing headaches due to stress.

Precautions

Contraindications: Pregnant women should avoid LI3 acupressure. Excessive pressure or prolonged acupressure can cause skin damage, so maintain appropriate intensity.
Guidance: If persistent pain continues for 3 days or longer or worsens, be sure to consult a healthcare professional. Acupoint acupressure is a complementary therapy and cannot completely replace disease treatment.
