12 Primary Channels of Acupuncture

Introduction

The 12 Primary Channels—also known as the 12 Regular Channels—form the core structure of acupuncture theory and clinical practice. These channels correspond to internal organ systems and provide pathways for regulating sensory, motor, and autonomic functions through acupuncture point stimulation.

Overview

Each of the 12 channels is bilateral and corresponds to a specific organ. These channels are essential for diagnosis and treatment in both traditional and modern acupuncture approaches. Most commonly used acupuncture points are located along these channels.

2. Large Intestine Channel (Hand Yangming)

Originating at the tip of the index finger, the Large Intestine Channel travels up the arm to the face. It’s used for head and face conditions like sinus congestion, toothaches, and sore throat, and also assists with bowel function.

This channel begins near the eye and descends through the body to the second toe. It governs digestive function and is frequently used for gastrointestinal complaints, emotional stress, and issues of the lower limbs.
