What is Zusanli (ST36)?
Zusanli (ST36) is one of the most important and effective acupoints in Oriental medicine. It is located on the Yangming Stomach Meridian (足陽明胃經), and as its name suggests, it means ‘three cun below the knee.’ It is an acupoint so effective for maintaining health that there is an old saying, ‘stimulating Zusanli once is equivalent to about 10 prescriptions.’
How to Find the Exact Location
Step 1: Identify the Basic Location
The outer lower part of the knee, specifically about 3 cun (approximately 10 cm) below the knee.
Step 2: Confirm the Detailed Location
When the knee is bent, descend vertically from the depression that appears on the outer side of the knee (outer eye of the knee) to reach a point 3 cun (approximately 10 cm) below. From this position, it is approximately one thumb width (about 1 cm) to the outer side of the front of the tibia (shin bone).
Step 3: Find the Exact Acupoint
The point where you feel a slight soreness or a refreshing sensation when pressed with your finger is Zusanli. It is located on both legs.
Acupressure Method
Preparation Stage
Sit or lie down in a comfortable position and relax the muscles of both legs. It is good to wash your legs with plenty of warm water before acupressure.
Basic Acupressure
Apply the tip or joint area of your thumb perpendicular to the acupoint and apply pressure slowly. Pressing too hard can cause injury, so adjust the pressure to about ‘refreshing soreness.’
Step-by-Step Acupressure Method
① Place your thumb on the acupoint and press slowly for 10-15 seconds.
② Massage in a clockwise circular motion (for about 1 minute).
③ Repeat releasing and reapplying your finger (10 times).
④ Alternate between both legs.
Adjusting Acupressure Intensity
It is good to start with light pressure and gradually increase the intensity. If severe pain occurs, stop immediately.

When is the Best Time to Apply Acupressure?

You can apply acupressure anytime during the day, but it is especially effective between 3-5 PM (when gastric activity is most active). Upon waking in the morning or 30 minutes to 1 hour after meals in the evening are also appropriate times.
Good Situations

Recommended Frequency
For prevention purposes, it is effective to apply acupressure 3-4 times per week; for symptom relief, 1-2 times daily is effective. Apply acupressure for about 5-10 minutes total, combining both legs.
