LI9 (Shanglian): The Point Three Cun Below the Elbow Crease

There is a reason LI9, also called Shanglian, is worth describing with a measurement instead of a promise. Its traditional location is specific: on the outer forearm, three cun below the elbow crease. That detail tells us where practitioners look; it does not turn one point into a diagnosis or a universal answer for bowel symptoms.

What is LI9 (Shanglian)?

LI9 is the point designation commonly called Shanglian in the Traditional Chinese Medicine (TCM) acupuncture-point system. It is listed on the Large Intestine channel. In standard point-location material, LI9 sits on the radial side of the posterior forearm, on the line between LI5 (Yangxi) and LI11 (Quchi), three cun below the elbow crease. The World Federation of Acupuncture-Moxibustion Societies point-location standard records that location.

A small but important detail: a cun is a traditional body-relative measurement, not a fixed ruler measurement for every person. Point location is assessed in context by a trained practitioner.

The evidence starts with the location

Name: LI9 is known as Shanglian.
Region: the outer, posterior forearm—not the hand and not the inside of the elbow.
Reference line: it is described between LI5 at the wrist and LI11 near the elbow.
Landmark: the standard location is three cun below the elbow crease.
Clinical context: in TCM, points are considered alongside a person’s symptoms, health history, and overall pattern—not in isolation.

That is why an accurate introduction to an LI9 acupressure point in Calgary should begin with orientation. A labelled point on an arm is useful context. It is not a reason to skip a proper assessment when something feels new, persistent, painful, or concerning.

How Traditional Chinese Medicine describes the point

Traditional Chinese Medicine has long grouped LI9 with the Large Intestine channel and discusses it within a broader pattern-based framework. The framework is traditional medical theory; it is not a guarantee that stimulating a point will resolve constipation or restore bowel regularity. The U.S. National Center for Complementary and Integrative Health notes that acupuncture is a component of TCM and that research findings vary by condition.

At Calgary Healing Hands Wellness, an acupuncture conversation begins with the person in front of us: what has changed, how long it has been happening, relevant health history, and whether acupuncture is an appropriate part of their care. One named point never replaces that conversation.

Constipation is a symptom, not a diagnosis

Constipation can have many causes, including routine changes, diet, hydration, medication, and underlying health conditions. A point-based wellness discussion should not make it feel like a problem to manage alone. Alberta guidance advises getting health advice when constipation does not improve or when there are concerning changes such as blood in the stool or unexplained weight loss. Read Alberta’s lower-bowel health guidance.

Seek timely medical care for severe or worsening abdominal pain, vomiting, fever, blood in the stool, unexplained weight loss, or bowel changes that persist. Alberta Health Services’ constipation resource is a helpful starting point for recognizing when a clinician should be involved.

Where acupuncture may fit

For people who are already working with their healthcare team, acupuncture may be a topic to discuss as part of a wider wellness plan. A registered practitioner can review whether care is suitable, explain what an appointment involves, and help keep complementary care in its proper place alongside medical advice.
