SI-11 Tianzong
SI-11 Tianzong (天宗) is a point on the Small Intestine meridian. In TCM theory it is described as influencing the channel's qi, and it is traditionally used in the context of the whole pattern rather than as a stand-alone remedy. This page explains how to locate it, what the tradition says about it, and how to press it safely.
Location
In the center of the infraspinous fossa of the scapula, about one-third of the way from the lower border of the scapular spine.
How to find it
Reach over the shoulder to the center of the shoulder blade. The point is in the belly of the muscle, roughly in the middle of the blade.
Traditional functions
- Moves qi and blood in the shoulder
- Relaxes the sinews
- Benefits the scapula and neck
Traditional uses
- Shoulder and scapular tension
- Neck stiffness
- Upper-back tightness
- Breast discomfort in some traditional texts
How to press it
Use a tennis ball against a wall, or have someone press with a thumb for 1 minute. Breathe and let the shoulder drop.
Acupressure is generally a gentle practice. Use the pad of the thumb or finger, start with light pressure, and increase only to a comfortable level. A mild ache or warmth is common; sharp pain is a signal to ease off.
Safety
Avoid direct pressure on an acute shoulder injury or over a bony prominence. Stop if you feel numbness down the arm.
How this is viewed today
SI-11 is used in trials for shoulder and neck pain, often with local needling. Evidence is limited.
