Tianfu (LU3) Acupoint — Complete Guide to Precise Location and Acupressure Technique

One-line summary: Tianfu (LU3) is an acupoint where lung qi gathers, and is exceptionally effective for relieving asthma, respiratory symptoms, nosebleeds, and arm pain.

What is Tianfu?

Tianfu (天府) is an acupoint on the Lung meridian, located on the inner side of the arm. “Tianfu” means “heaven’s chamber,” referring to an important point where the clear qi of the lungs gathers like the heavens. This acupoint has been widely used for respiratory and circulatory conditions, and remains effective in modern times for relieving symptoms such as asthma, cough, and shortness of breath.

How to Find the Exact Location

Step 1: Lower your arm naturally to the side.

Step 2: Locate the armpit crease (where the armpit meets the arm).

Step 3: Mark a point approximately 3 cun below that crease (cun is a unit used in traditional Chinese medicine, equal to three times the width of an individual’s thumb).

Step 4: The point is located on the outer side of the biceps muscle, or slightly inward from the outer side of the arm. When you press with your finger and feel slight tenderness, you have found the correct location.

Acupressure Method

Basic acupressure technique: Place the tip of your thumb perpendicular to the Tianfu acupoint and press slowly. Start gently at first and gradually increase the pressure. Press for 3 seconds and rest for 2 seconds, repeating 10 times.

Acupressure with breathing: Slowly inhale through your nose while increasing the intensity of the pressure, and slowly exhale through your mouth while releasing the pressure. Repeat this for about 5 minutes for even more effective relief of respiratory symptoms.

Combined with warm compress: Applying a warm towel to the arm for about 5 minutes before acupressure helps relax the muscles and enhances the effectiveness of the pressure.

Key Benefits

  • Relief of asthma and shortness of breath: Normalizes lung qi to reduce asthma attacks and ease breathing.
  • Treatment of nosebleeds (epistaxis): Used as an emergency acupressure point to cool excess lung heat and stop nosebleeds.
  • Relief of arm pain: Effectively improves pain, numbness, and fatigue throughout the entire arm from shoulder to wrist.
  • Suppression of cough: Relieves dry cough from colds and chronic cough.
  • Mental calm: Corrects the qi of the Lung meridian to reduce anxiety and depression.

When is Acupressure Most Beneficial?

Optimal time: Between 3 a.m. and 5 a.m. is when the Lung meridian is most active, so acupressure during this time maximizes its effects. However, in daily life, you can apply pressure whenever symptoms appear.

Recommended situations: It is effective when an asthma attack begins, when experiencing a nosebleed, when your arm is numb or painful, when coughing is severe, or when stress causes shallow breathing.

Frequency of acupressure: For chronic conditions, apply pressure consistently twice a day (morning and evening) for 5 minutes each. For acute symptoms, apply pressure as needed.

Precautions

Cases to avoid: Avoid areas with severe inflammation or damaged skin. If you are pregnant or have a serious condition, consult with a professional before proceeding.

Avoid excessive stimulation: Pressing too hard can cause bruising or muscle damage. A slight amount of tenderness is sufficient, and stop if you feel discomfort.

Hygiene management: Wash your hands and arm thoroughly before acupressure, and avoid any infected wounds.

Medical consultation: Acupoint acupressure is a supplementary health management method and is not a complete treatment for serious conditions. If chronic or acute symptoms persist, be sure to consult a doctor or traditional Chinese medicine practitioner.

🤰 Pregnancy Warning: Some acupoints such as Sanyinjiao (SP6), Hegu (LI4), and Taichong (LR3) can trigger uterine contractions in pregnant women. If you are pregnant or may be pregnant, be sure to consult with a traditional Chinese medicine practitioner or healthcare professional before proceeding.
