What is Shanglian?
Shanglian (上廉) is an acupoint belonging to the Large Intestine Meridian (LI9). “Shang” means upper and “lian” means narrow opening. Located on the outer side of the forearm, it plays an important role in regulating large intestine function and relieving pain throughout the arm. In traditional medicine, Shanglian is used to improve the flow of qi and blood and reduce inflammation.
How to Find the Exact Location
Step 1: Bend your arm at a 90-degree angle and find the creased area on the inner side of your elbow. This point is Quchi (LI11).
Step 2: Measure approximately 3 cun (about 9cm) from Quchi toward the wrist. A cun is an anatomical unit of measurement, roughly equivalent to the width of three fingers.
Step 3: Follow the outer line of the forearm (toward the thumb side) downward and find the small depression between the bone and muscle. This is Shanglian.
Step 4: When you gently press with your finger, you should feel a slight hollow sensation above the bone to confirm the correct location.
Acupressure Technique
Preparation: Sit or lie down in a comfortable position with your arm relaxed.
Step 1: Locate the Shanglian acupoint using the tip of your thumb.
Step 2: Gradually increase pressure and press for about 3-5 seconds, then release. You should feel a soreness rather than sharp pain.
Step 3: Repeat this action 5-10 times.
Step 4: Apply the same technique to both arms.
Tip: If your nails are long, you can press with the first joint of your finger instead.
Main Benefits
- Abdominal Pain Relief: Regulates large intestine function to improve abdominal cramps and pain.
- Shoulder Pain Relief: Improves qi and blood circulation in the meridians connecting the arm and shoulder, alleviating shoulder stiffness.

When is the Best Time to Practice Acupressure?
Optimal Time: Between 9 AM and 11 AM, when the qi of the Large Intestine Meridian is most active, acupressure is more effective during this time window.
Situation-Based Timing: You can apply acupressure immediately when you have abdominal pain, shoulder stiffness, or arm numbness. For chronic pain, it is best to practice at the same time every day.
Recovery Period: Initially, continue for about 1 week, 1-2 times per day to see results. After symptom improvement, you can maintain the benefits with acupressure 3-4 times per week.
Precautions
Be aware of important precautions when practicing acupressure on Shanglian. First, avoid excessive pressure. While you should feel soreness, stop immediately if sharp pain appears. Second, avoid acupressure if your skin is damaged or inflamed. Third, if you are pregnant or have a serious medical condition, consult a healthcare professional before proceeding. Fourth, avoid exposure to cold air for 30 minutes after acupressure. Fifth, avoid acupressure within 1 hour after eating or after excessive exertion. If symptoms persist or worsen, be sure to seek a diagnosis from a medical professional.
