Yinlingquan (SP9) Acupoint — Complete Guide to Precise Location and Acupressure Technique

What is Yin Ling Quan?

Yin Ling Quan (陰陵泉, SP9) is an important acupoint belonging to the Spleen meridian (脾經). In traditional Chinese medicine, this acupoint is regarded as “a key point for eliminating dampness and strengthening digestive function.” It supports spleen function and normalizes the body’s water metabolism, delivering excellent results for swelling reduction and digestive health.

How to Locate the Exact Position

Step 1: Bend your knee and locate the medial (inner) side of the tibia (shinbone) below the knee.

Step 2: Move downward along the medial border of the tibia until you find a depression (concave area) where the bone indents.

Step 3: Yin Ling Quan is located in the depression on the medial side of the tibia, approximately 10-12 cm above the inner ankle bone.

Finding Tip: The correct location is the area that produces slight tenderness when pressed with your finger. It exists on both legs.

Acupressure Method

Basic Position: Sit or lie down in a comfortable position with your knee slightly bent.

Acupressure Steps:

1. Locate Yin Ling Quan (SP9) using your thumb or middle finger.
2. Apply pressure vertically and slowly, pressing for 3-5 seconds.
3. Stimulate with enough intensity to feel slight soreness (level 7-8).
4. Press alternately on both legs, 10 times each.
5. It is most effective to perform this once or twice daily, in the morning and evening.

Additional Tip: Drinking warm water after acupressure enhances the effect. Avoid pressing immediately after meals or excessive exertion.

Main Benefits

• Swelling Reduction: Normalizes the body’s water metabolism to quickly reduce swelling in the legs and face.
• Improved Abdominal Distension: Expels abdominal gas and promotes digestive function, relieving bloated sensations.
• Relief from Diarrhea and Indigestion: Strengthens spleen and stomach function to improve intestinal health.
• Knee Pain Relief: Improves meridian flow to reduce pain and discomfort around the knee.
• Promoted Metabolism: Activates the body’s metabolism to improve overall health.

When Is the Best Time to Press?

Optimal Time: The Spleen meridian is most active between 9-11 AM, making this the most effective time to practice acupressure. However, pressing 30 minutes to 1 hour after meals is especially effective for promoting digestion.

Good Situations:

• When your legs frequently swell in the morning
• When digestion is poor after meals or abdominal distension occurs
• When experiencing diarrhea or constipation
• When experiencing pain or discomfort around the knee
• When weight is increasing or metabolism feels sluggish

Precautions

Cases to Avoid: Consult with a healthcare professional before pressing if you are pregnant or have a serious illness. Also avoid if there is severe injury or inflammation on the leg.

Cautions During Acupressure: Excessive pressure can be harmful, so maintain appropriate intensity. Stop immediately if you experience severe pain or discomfort during pressing. Consult with medical professionals if you have skin wounds or are undergoing treatment for a condition.

Duration of Effects: Results vary by individual, but effects can typically be felt within 2-3 weeks of regular acupressure. Chronic conditions require longer-term management.
