Shousanli (L.I-10), also known as the “Arm Three Miles,” is a well-recognized acupressure point on the Large Intestine meridian. It’s traditionally used in both acupuncture and acupressure to revitalize the upper limbs, regulate qi and blood, and alleviate pain in the arm and shoulder. In modern practice, it’s a go-to point for managing tennis elbow, boosting local circulation, and supporting immune and digestive health.
Clinically, Shousanli is especially relevant for those experiencing weakness or pain in the forearms, shoulders, or elbows. It is often combined with other points in protocols aimed at addressing musculoskeletal and gastrointestinal issues. The name “Three Miles” refers to its invigorating effects, just like ST-36 (Leg Three Miles). This point is known to restore energy and increase stamina.

Clinical Significance & Associated Conditions
Shousanli is commonly used for:
- Musculoskeletal issues: Pain, stiffness, or weakness in the elbow, upper arm, and shoulder.
- Neuromuscular tension: It helps regulate local qi and blood flow, making it valuable in treating conditions like tennis elbow and repetitive strain injuries.
- Energetic imbalance: As a yangming meridian point, it’s linked to digestive function and systemic energy regulation.
- Immune and gut support: Often included in acupressure protocols to strengthen general vitality and resilience, especially during seasonal shifts.
Location
To locate Shousanli:
- Bend the arm at a right angle.
- Measure two finger widths (approximately 3–4 cm) below the outer crease of the elbow (L.I-11).
- Follow the line that connects L.I-5 (on the wrist) to L.I-11—you’ll find L.I-10 in the muscle belly of the forearm extensor group.

Benefits and Common Uses
Shousanli offers a wide range of therapeutic effects:
- Reduces inflammation in the forearm and elbow
- Restores muscular strength after strain or overuse
- Promotes qi and blood circulation in the upper limbs
- Eases stiffness in the shoulder joint
- Improves immune function (often paired with ST-36 for full-body tonification)
- Supports digestive health, especially with bloating or sluggish intestines
Physiological Functions & Mechanisms
In Traditional Chinese Medicine (TCM), L.I-10 is a yangming meridian point—known for its abundance of qi and blood. It helps mobilize stagnant energy, particularly in the significant intestine pathway, which spans from the fingers to the face. Its deep stimulation can:
- Activate the radial nerve region and local circulation
- Modulate muscle tone and elasticity
- Enhance gut motility through meridian-organ associations
Practitioner Insight
I often include Shousanli in treatments for clients with postural arm fatigue, especially those who work at a desk or frequently lift children. It’s incredibly responsive. I’ve also found it helpful for rebalancing after illness; it brings strength back to the upper body in a way that feels grounding and revitalizing.
Safety & Contraindications
- Avoid pressing over irritated, bruised, or inflamed skin.
- Use lighter pressure if there’s recent injury or acute inflammation in the forearm.
- May be too stimulating for individuals running a fever.
- Always warm up the area gently before stimulation.
- Refer to our acupressure safety guide for more details.
- See more under acupressure.
As always, listen to your body and stop if discomfort arises.
Related Points & Techniques
For synergistic effects, pair Shousanli with:
- LI 4 – Hegu (Joining the Valley)
- LI 11 – Quchi (Pool at the Bend)
- ST 36 – Zusanli (Leg Three Miles)
- Add breathing techniques or moxibustion to enhance warming and circulation
- Use with tennis elbow taping or ergonomic stretches for longer-term relief

Scientific Perspective
Modern studies support the role of L.I-10 in improving motor function and reducing muscle fatigue. Some trials have shown enhanced muscle activation and pain threshold when this point is stimulated as part of rehabilitation for elbow tendinopathy and shoulder conditions. Research also supports its inclusion in immune regulation protocols when paired with ST-36 (PubMed).
