Fenglong (ST40) Acupoint — Complete Guide to Precise Location and Acupressure Technique

One-Line Summary: Fenglong (ST40) is a key acupoint on the leg that eliminates phlegm and relieves cough, sputum, and dizziness.

What is Fenglong?

Fenglong (豐隆) is an acupoint on the Stomach Meridian (Foot-Yangming Stomach Meridian), and its name means “abundant and elevated.” In Traditional Korean Medicine, it is considered especially effective for eliminating damp-phlegm and is an important acupoint that supports the health of both the digestive and respiratory systems. It is widely used for various symptoms including dizziness, headaches, and cough.

How to Find the Exact Location

Easy Way to Find It: Sit with your legs extended and locate the outer ankle bone (lateral malleolus). From that point, move upward toward the knee about 4 finger widths (approximately 8 cun). You’ll find an indentation on the outer side of the tibia (shinbone). This is Fenglong. To be more precise, it’s located about 2 finger widths lateral to the tibia. The acupoint is present on both legs.

Acupressure Method

Step-by-Step Technique: Step 1: Sit or lie down in a comfortable position and relax your legs. Step 2: Locate the Fenglong acupoint using your thumb or middle finger. Step 3: Slowly exhale while gradually applying pressure for 3-5 seconds. Step 4: Inhale slowly while gradually releasing the pressure. Step 5: Repeat this 10-15 times. Tip: Don’t press too hard; aim for a gentle, soreness sensation that feels relieving.

Key Benefits

  • Respiratory Health: Relieves cough and sputum, improves breathing difficulties
  • Improved Circulation: Reduces swelling and heaviness in the legs
  • Brain Health: Alleviates dizziness, headaches, and vertigo
  • Digestive Improvement: Normalizes stomach function and eliminates damp-phlegm
  • Sound Sleep: Promotes nerve relaxation and improves sleep quality

When to Practice Acupressure

Fenglong can be stimulated at any time of day. It’s especially helpful to practice acupressure after waking in the morning or before bed in the evening when cough and sputum are severe. If you experience dizziness, immediate acupressure can provide quick symptom relief. It is recommended to practice 1-2 times per day, performing 10-15 presses each time.

Precautions

For Safe Acupressure: If you are pregnant or have a serious illness, consult a professional before practicing. If pain increases or symptoms worsen after acupressure, stop and seek medical advice. Avoid over-stimulation as it may damage the skin; practice only 1-2 times per day. Avoid acupressure within 1 hour after eating, and skip it when you are excessively fatigued.

🤰 Pregnancy Caution: Certain acupoints such as Sanyinjiao (SP6), Hegu (LI4), and Taichong (LR3) may trigger uterine contractions in pregnant women. If you are pregnant or may be pregnant, be sure to consult with a Traditional Korean Medicine practitioner or medical professional before practicing acupressure.
