Acupuncture Channels & Collaterals Guide
Acupuncture channels, also known as meridians, form the structural and functional pathways that guide the therapeutic application of acupuncture. These channels serve as a framework for diagnosing and treating various conditions. Understanding the different types of channels and their relationships is essential for effective acupuncture practice.
Key Points
Acupuncture channels facilitate the movement of qi and blood throughout the body.
The 12 primary channels correspond to major organs and are the foundation of acupuncture treatment.
Divergent channels provide deeper connections between primary channels and internal structures.
Extraordinary vessels regulate systemic energy and serve as reservoirs for qi and blood.
Luo-connecting channels link paired organs and play a role in chronic conditions.
Sinew channels influence muscular and tendon function and are critical in treating musculoskeletal pain.
What Are Acupuncture Channels?
Acupuncture channels are pathways through which qi and blood circulate. They interconnect organs, tissues, and the body’s surface, playing a vital role in homeostasis and disease treatment.
The 12 Primary Channels
The primary channels form the foundation of acupuncture theory. Each is associated with a specific zang-fu organ and follows a unique trajectory.
| Primary Channel | Zang-Fu Pair | Pathway Summary |
|---|---|---|
| Lung (LU) | Lung & Large Intestine | Begins in the middle jiao, ascends to the lungs, and travels along the arm to the thumb. |
| Large Intestine (LI) | Large Intestine & Lung | Starts at the index finger, travels up the arm, crosses to the opposite side of the face. |
| Stomach (ST) | Stomach & Spleen | Begins at the nose, descends through the chest, stomach, and down the leg to the second toe. |
| Spleen (SP) | Spleen & Stomach | Starts at the big toe, ascends the leg, passes through the abdomen to the spleen. |
| Heart (HT) | Heart & Small Intestine | Originates in the heart, travels down to the small intestine and up the arm to the pinky. |
| Small Intestine (SI) | Small Intestine & Heart | Begins at the pinky, runs up the arm to the face, connecting with the ear. |
| Bladder (BL) | Bladder & Kidney | Starts at the inner eye, travels down the spine, through the leg, to the little toe. |
| Kidney (KI) | Kidney & Bladder | Begins at the sole, ascends along the leg, through the abdomen, to the chest. |
| Pericardium (PC) | Pericardium & Sanjiao | Starts in the chest, descends through the diaphragm, moves up the arm. |
| Sanjiao (SJ) | Sanjiao & Pericardium | Starts at the ring finger, moves up the arm, to the ear, and circles the eye. |
| Gall Bladder (GB) | Gall Bladder & Liver | Begins at the outer eye, zigzags down the body to the fourth toe. |
| Liver (LV) | Liver & Gall Bladder | Starts at the big toe, ascends the leg, passes through the abdomen, reaching the liver. |

Divergent Channels
Divergent channels are deeper branches of primary channels that connect to internal organs beyond their paired zang-fu relationship. They:
Strengthen the connection between yin and yang channels.
Provide deeper pathways for chronic conditions and latent pathogens.

The Eight Extraordinary Vessels
Unlike primary channels, extraordinary vessels do not belong to a specific zang-fu pair. They:
Act as reservoirs for qi and blood.
Regulate the body's overall energetic balance.
Influence deep physiological processes such as reproduction, development, and aging.

Luo-Connecting Channels
Luo-connecting channels serve as a bridge between interior-exterior paired channels, playing a role in:
Balancing excess and deficiency conditions.
Addressing psycho-emotional disorders.
Managing chronic conditions and blood stasis.
➡️ Understanding Luo-Connecting Channels
Sinew Channels
Sinew channels follow the course of the primary channels but are more superficial. They:
Connect muscles, tendons, and ligaments.
Influence movement and postural alignment.
Play a key role in sports acupuncture and pain management.

Conclusion
Acupuncture channels form a comprehensive network that connects all body systems. Understanding the roles of primary, divergent, extraordinary, luo-connecting, and sinew channels allows practitioners to select the most effective treatment strategies.
Frequently Asked Questions (FAQ)
Q: How do acupuncture channels function scientifically?
Research suggests that acupuncture channels correlate with myofascial pathways, nervous system networks, and interstitial fluid circulation.
Q: What’s the difference between primary and extraordinary channels?
Primary channels are directly linked to zang-fu organs, while extraordinary vessels regulate the body’s overall energy balance.
Q: Which acupuncture channels are most important for pain relief?
Sinew channels and luo-connecting channels are particularly useful for musculoskeletal pain and chronic conditions.
