The Lung Meridian of Hand Taiyin: Complete Pathway, Points & Functions Guide
The Lung Meridian of Hand Taiyin is one of the twelve primary channels in Traditional Chinese Medicine and serves as the foundational pathway for understanding respiratory health, immune function, and the body's relationship with the external environment. As the first channel in the classical meridian sequence, the Lung channel governs the distribution of Qi and defensive energy throughout the body, making it essential for practitioners and students of acupuncture and TCM to understand thoroughly.
This comprehensive guide explores the complete pathway of the Lung meridian, from its internal origins in the middle jiao to its termination at the thumbnail, examines each of the eleven acupuncture points along the channel, and explains the clinical significance of this Metal element meridian. Whether you're a TCM student preparing for certification, an acupuncturist deepening your channel knowledge, or simply curious about how Eastern medicine views the respiratory system, this guide provides the foundational understanding you need.

Welcome to the Meridian Exploration Series
Traditional Chinese Medicine is a holistic medical system rooted in the understanding that the body functions as an interconnected whole, guided by principles of balance, harmony, and dynamic movement. Health is maintained when Qi, Blood, and body fluids flow smoothly and the internal organ systems work together in balance; illness arises when that harmony is disrupted.
Central to this system are the body's energetic pathways, known as meridians (also commonly referred to as channels), which serve as the functional expressions of the Zangfu organ systems. These channels are classically named according to their yin-yang designation and whether they travel on the hand or foot, such as the Hand Taiyin Lung Channel or the Foot Jueyin Liver Channel. Each yin Zang organ is paired with a yang Fu organ, and together their channels share a Five Element association.
Throughout this series, we will explore each primary channel in depth, examining its pathway, key acupuncture points, clinical functions, and elemental correspondences.
What Is the Lung Channel of Hand Taiyin?
The Lung Meridian, also called the Hand Taiyin Lung Channel, is one of twelve primary energy pathways in Traditional Chinese Medicine that governs respiration, immunity, and the distribution of protective Qi throughout the body. It contains 11 acupuncture points running from the chest to the thumb.
Origin and Internal Pathway
According to classical texts, the Lung Channel of Hand Taiyin originates in the middle jiao, in the region of the stomach. From there, it descends internally to connect with the Large Intestine, then ascends through the diaphragm to enter the Lung. The channel continues upward to the throat, where it influences the voice and respiration, before emerging externally at Lung 1 (Zhongfu) in the chest.
External Pathway Along the Arm
From this point, the channel travels along the anteromedial aspect of the arm and forearm, passing the wrist and palm, and ultimately terminates at Lung 11 (Shaoshang) on the radial corner of the thumbnail.
Through this pathway, the Lung Channel governs respiration, the diffusion and descent of Lung Qi, and the distribution of Wei Qi (the body's defensive energy). When the Lung Channel is out of balance, this may manifest as weakened immunity, frequent colds, cough, shortness of breath, nasal congestion, skin dryness, or sweating disorders. Because the Lung controls the exterior and opens to the nose, imbalances along this channel often affect the body's ability to defend against external pathogens and maintain healthy boundaries between the internal and external environment.
Key Acupuncture Points on the Lung Meridian
The Lung Channel of Hand Taiyin emerges externally on the lateral aspect of the chest at Lung 1 (Zhongfu) and travels down the anteromedial aspect of the arm and forearm, passing the elbow and wrist, before terminating at the Jing-Well point, Lung 11 (Shaoshang) at the radial corner of the thumbnail.
Five Shu Points of the Lung Channel
Along this course, the channel includes the classical Five Shu points, which represent different depths and energetic qualities:
Lung 11 (Shaoshang) - Jing-Well point
Lung 10 (Yuji) - Ying-Spring point
Lung 9 (Taiyuan) - Shu-Stream and Yuan-Source point (where the channel's original Qi resides)
Lung 8 (Jingqu) - Jing-River point
Lung 5 (Chize) - He-Sea point at the elbow
Clinically Important Lung Points
In clinical practice, several additional Lung points are commonly used:
Lung 7 (Lieque) - Luo-connecting point influencing both the Lung and its paired Large Intestine channel
Lung 6 (Kongzui) - Xi-Cleft point for acute or severe conditions
Lung 1 (Zhongfu) - Front-Mu point for local chest and respiratory issues
In some non-classical clinical systems, Lung 4 (Xiabai) is referred to as a "control point" for assessing overall channel balance, reflecting specific diagnostic approaches rather than traditional point categorization.
Classical Associations of the Lung Channel
Metal Element and Five Element Theory
The Lung Channel of Hand Taiyin is associated with the Metal element and reflects qualities of structure, refinement, and regulation. Its corresponding season is autumn, a time of contraction and letting go, and its associated climate is dryness, which directly relates to the Lung's role in regulating moisture and body fluids.
Seasonal and Climatic Associations
The Lung is linked to the color white, the taste pungent, and the direction west. Its associated climate of dryness reflects the organ's vulnerability to dry conditions and its role in managing body fluids and moisture.
Emotional and Sensory Connections
Emotionally, the Lung is associated with grief and sadness, reflecting its role in processing loss and facilitating release. The Lung opens to the nose and governs the skin and body hair, emphasizing its control over the exterior of the body and the first line of defense against external pathogens.
The paired yang organ of the Lung is the Large Intestine, and together they form a functional yin-yang relationship within the Metal element. The Lung Channel is most active between 3:00 and 5:00 a.m., according to the Chinese organ clock, a time associated with respiration, renewal, and the body's preparation for the day.
Functions and Roles of the Lung Meridian
Regulates Respiration and Qi Distribution
The Lung meridian governs the process of breathing and the distribution of air throughout the body. It controls the overall vitality and energy levels by managing how Qi moves and circulates.
Controls Wei Qi and Immunity
The Lung provides a protective barrier against external pathogens by distributing Wei Qi (defensive energy). This function directly relates to immune strength and the body's ability to resist illness.
Governs Skin, Hair, and Body Fluids
The Lung helps maintain hydration and health of the skin and body hair. It plays a role in fluid metabolism and moisture regulation, which is why Lung imbalances often manifest as skin dryness or sweating disorders.
Additional Functions
Opens to the nose: Directly connected to the respiratory tract and sense of smell
Balances fluids: Influences water passages and fluid distribution
Controls descent of Qi: Ensures Qi moves downward properly rather than rebelling upward
Common Lung Channel Imbalances and Patterns
When the Lung Channel is out of balance, symptoms often reflect the type of pathogenic influence involved.
Wind Invasion Symptoms
Wind commonly affects the lungs first, leading to acute symptoms such as cough, sneezing, sore throat, or chills. This is often the beginning stage of colds and respiratory infections.
Heat, Cold, and Phlegm Patterns
Heat in the Lung may present as:
Fever
Thick yellow phlegm
Sore throat
Dryness and inflammation of the nose and skin
Cold can impair the Lung's ability to disperse and descend Qi, resulting in:
Cough with clear phlegm
Chest tightness
Sensitivity to cold
Dampness or phlegm may obstruct the Lung channel, causing:
Heaviness in the chest
Congestion
Wheezing
Chronic cough
Deficiency vs. Excess Presentations
Because the Lung governs the exterior and defensive Qi, imbalances often affect immunity, respiration, skin health, and the body's ability to adapt to environmental changes. Deficiency patterns typically show weakness and vulnerability, while excess patterns involve obstruction and stagnation.
