Chize (LU5) Acupoint — Complete Guide to Precise Location and Acupressure Technique

About Chize

Chize (尺澤) is an acupoint belonging to the Lung meridian (肺經) and is an important acupoint in traditional medicine for addressing respiratory health and arm pain. It is known to support lung function, clear heat, and rapidly alleviate symptoms related to the throat and lungs. Also called by the code name LU5, it is frequently used especially for colds and allergic coughs caused by seasonal changes.

How to Find the Exact Location

Step 1: With your arm extended, locate the inner crease of the elbow (when the elbow is extended).
Step 2: From the center of the elbow crease, move approximately 1 cm toward the thumb side (lateral side).
Step 3: It is located above the elbow crease when the arm is bent, on the outer side of the biceps tendon.
Step 4: When pressed with a finger, you can feel slight pain or soreness. This point is Chize.

Acupressure Method

Preparation: Sit in a comfortable position and extend the arm to be massaged.
Step 1: Using the tip of the thumb on the opposite hand, locate the Chize point.
Step 2: Apply gentle pressure while rubbing in circular motions or pressing vertically.
Step 3: Maintain a pressure level that is slightly uncomfortable but tolerable, applying pressure for 3-5 seconds.
Step 4: Slowly release the pressure and repeat 10-15 times.
Tip: The effect is better when applying pressure with warm hands, and it is beneficial to perform this 2-3 times per day.

Main Benefits

• Cough relief: It effectively works for both dry coughs and coughs with phlegm
• Asthma symptom improvement: It helps ease breathing during shortness of breath and asthma attacks
• Sore throat relief: It rapidly alleviates throat pain and cold-related throat symptoms
• Fever reduction: It improves early cold symptoms through its heat-clearing effect
• Elbow pain relief: It alleviates pain and numbness symptoms around the elbow

When Is It Good to Apply Pressure?

Optimal time: It is effective to apply pressure immediately when coughs are severe in the morning, before going to bed at night, and when symptoms appear.
Situation-specific recommendation: It is good to apply pressure when you have a cough due to a cold, as preventive pressure for those with asthma, when your throat feels irritated from a sore throat, and after work that frequently uses the elbow. Regular pressure massage during seasonal transitions or changes is particularly helpful for maintaining respiratory health.

Precautions

Cases to avoid: Avoid acupressure if there are wounds or inflammation on the skin, and consult with a healthcare professional before proceeding if you are pregnant or have a serious illness.
Correct intensity: Applying too much pressure can cause bruising, so always maintain a pressure level that is “slightly uncomfortable but tolerable.”
Persistent symptoms: If symptoms do not improve after one week or more, visit a clinic or hospital to receive an accurate diagnosis.
