ST36 is used in acupuncture treatment to help ease digestive discomfort, address fatigue, and support immune health as part of an individualized treatment plan.
If you’ve ever finished a meal feeling bloated and too sluggish to get back to your day, you know how digestive discomfort and low energy can overlap. These are concerns an acupuncturist may consider when choosing ST36.
Also called Zusanli or “Leg Three Miles,” ST36 sits just below the knee, a location that may surprise you when your stomach is the source of discomfort. In Chinese medicine, it belongs to the stomach meridian and has a long history of use for digestion and stamina. Whether it is included in your care depends on your symptoms, health history, and personal needs.
Key Takeaways
- ST36 is below the knee, slightly outside the shinbone.
- It is commonly used for nausea, bloating, poor appetite, constipation, loose stools, and abdominal discomfort.
- Acupuncturists may select it when tiredness occurs alongside digestive trouble or a slow recovery.
- It may be included in care intended to support a balanced response to stress and illness.
- Acupuncture needles should be placed only by a qualified professional.
What is ST36?
ST36 is an acupuncture point on the lower leg. Its Chinese name, Zusanli, is often translated as “Leg Three Miles.”
The name reflects a traditional belief that stimulating this point could help a tired person walk farther. It evokes the image of a weary traveler resting aching legs before continuing another three miles. This connection to endurance makes the name a memorable reminder of ST36’s traditional use for low stamina, weakness, poor digestion, and feeling worn down.
ST36 belongs to the stomach meridian, a pathway described in Chinese medicine. Although the point is below the knee, practitioners may select it for digestive symptoms. Its place on this traditional pathway does not mean it has a direct physical connection to the stomach.
Where is ST36 located?
ST36 is found on both legs. It sits about four finger-widths below the bottom of the kneecap and roughly one finger-width outside the sharp edge of the shinbone.
To find the general area:
- Sit with your knee bent and your leg relaxed.
- Place four fingers across the leg just below the kneecap.
- Find the hard ridge running down the front of the shin.
- Move one finger-width toward the outside of the leg.
- Press gently into the soft muscle beside the bone.
You should be pressing the muscle, not the shinbone. The exact position differs slightly from person to person because bodies have different proportions.
This method gives you a rough location for acupressure. A trained acupuncturist uses touch, body landmarks, and your individual anatomy to locate the point before needling.
Professional Needling of ST36
ST36 may be needled straight or at a slight angle. The angle and depth depend on the patient’s body, comfort, and health needs. Needling should be performed only by a qualified acupuncturist.
Common Uses of ST36
- Digestion: Bloating, nausea, constipation, loose stools, reflux, and stomach discomfort.
- Energy: Tiredness, weakness, low stamina, and post-illness recovery.
- Physical comfort: Knee pain, tired legs, and muscle tension.
- General recovery: Appetite, rest, and well-being during stressful periods.
- Immune health: Support during recovery without claiming to prevent or cure illness.
Symptoms That May Lead to ST36 Treatment
- Low energy or general weakness
- Nausea or poor appetite
- Bloating or abdominal discomfort
- Constipation or loose stools
- Acid reflux
- Knee pain or stiffness
- Tired or heavy legs
- Slow recovery after illness
Points Commonly Paired With ST36
The combinations below are examples of points an acupuncturist may pair with ST36.
- ST36 + SP6: Digestion, circulation, and tiredness.
- ST36 + PC6: Nausea, vomiting, and acid reflux.
- ST36 + LI10: Low energy and weakness.
- ST36 + GB34: Knee pain, stiffness, and leg movement.
- ST36 + CV12: Stomach discomfort, fullness, and bloating.
- ST36 + BL20 + BL21: Long-term digestive trouble with fatigue.
- ST36 + KI3: Weakness, tiredness, and circulation concerns.
Practitioners choose points based on each patient’s symptoms, health history, and overall assessment, rather than following a fixed formula for each symptom. Two people with the same concern may receive different combinations.
Tracking Your Response to Treatment
Responses differ. A person receiving treatment for mild nausea may notice a change during or soon after a visit. Bloating, bowel changes, and long-standing fatigue may take longer.
Your general health, the cause of your symptoms, their duration, and the rest of your care can all affect the outcome.
Use a clear symptom to judge whether treatment is helping. You might track how often nausea occurs, how uncomfortable you feel after eating, or how many days you go without a bowel movement. This is more useful than waiting for a vague sense that something has changed.
If several visits bring no improvement, speak openly with your acupuncturist. The treatment plan may need to change, or your symptoms may need another type of assessment.
ST36 Acupuncture or Acupressure: Which Should You Choose?
ST36 acupressure is a gentle option for mild nausea, bloating, or tiredness at home. ST36 acupuncture provides more personalized care based on your symptoms and health history. Neither option should replace medical care for severe or lasting symptoms.
When to Seek Medical Care
ST36 should not be used to manage a medical emergency or delay an assessment.
Seek medical care for:
- severe or worsening abdominal pain;
- blood in vomit or stool;
- black stool;
- repeated vomiting;
- trouble keeping fluids down;
- unexplained weight loss;
- difficulty swallowing;
- fever with abdominal pain;
- a hard or swollen abdomen;
- constipation with vomiting or inability to pass gas;
- chest pressure that feels like indigestion;
- severe or unexplained fatigue.
These symptoms may need testing and medical treatment.
