The Lung Meridian is a foundational channel, considered one of the principal conduits of Qi and deeply connected to our vitality, interface with the world, and emotional resilience.
Core Functions of the Lung in TCM
The Lung is called the "Delicate Organ (Jiāo Zàng) because it is the most external of the Yin organs, directly interfacing with the environment via breath. Its key functions are:
1. Governs Qi and Respiration:
It is the primary site of Zong Qi or "Chest Qi" formation, which is created from the air we breathe and the essence from food. This Qi powers the heart and respiration, and its strength is felt in the voice.
· A healthy Lung ensures smooth, deep breathing and strong, clear Qi throughout the body.
2. Controls the Dispersing and Descending of Qi & Body Fluids:
Dispersing: Spreads Defensive Wei Qi and bodily fluids to the skin and body hair to warm and protect the surface. It also "opens" the pores.
Descending: Sends Qi and fluids downward to the kidneys and bladder. This function prevents coughing and asthma (which is seen as rebellious, upward Qi) and ensures proper urination.
3. Regulates the Water Passages:
By dispersing and descending fluids, the Lung plays a crucial role in metabolism, directing fluids to the skin (as sweat) and down to the kidneys (as urine).
4. Controls the Skin and Body Hair:
The Lung moistens and nourishes the skin through its dispersing function. The quality of the skin, sweat, and even body hair (its lustre and strength) reflects Lung Qi. This is why skin conditions like eczema or dryness are often related to the Lung.
5. Houses the Po– The Corporeal Soul:
· The Po is the most physical of the "souls" in TCM, governing physical sensations, reflexes, and our animal instinct for survival. It is connected to grief and letting go. A healthy Lung Po gives us a sense of presence, instinctual knowing, and the ability to grieve healthily and release what is no longer needed.
Common Pathological Patterns
When the Lung meridian or organ is imbalanced, it manifests in characteristic ways:
· Lung Qi Deficiency: Shortness of breath, weak voice, spontaneous daytime sweating, fatigue, weak cough, prone to colds. (Voice is a key indicator).
· Lung Yin Deficiency : Dry cough (especially at night), dry throat, night sweats, feeling of heat in the palms/chest.
· Invasion of Wind-Cold: Severe chills, mild fever, itchy throat, clear/white phlegm, nasal congestion. (The "common cold" pattern).
· Invasion of Wind-Heat: Sore throat, yellow phlegm, fever more than chills, thirst. (The "flu" pattern).
· Lung Heat/Phlegm Heat: Cough with thick yellow/green phlegm, wheezing, fever, chest pain.
Important Acupuncture Points
· LU-1 (Zhongfu, "Central Treasury"): Front Mu point of the Lung. Treats cough, asthma, chest fullness, and shoulder pain.
· LU-5 (Chize, "Cubit Marsh"): He-Sea (Water) point. Clears Lung Heat, resolves phlegm, and regulates the Water Passages (for edema).
· LU-7 (Lieque, "Broken Sequence"): A major command point. Confluent point of the Conception Vessel. Opens the head & neck, releases exterior Wind (colds/flu), powerfully relieves cough and headaches, and promotes the descending function of the Lung.
· LU-9 (Taiyuan, "Great Abyss"): Source (Yuan) point and Earth point. Tonifies Lung Qi and Lung Yin, strengthens the pulse, and benefits the voice.
· LU-11 (Shaoshang, "Lesser Shang"): Well (Jing) point, Wood point. Used for acute sore throat, loss of voice, and febrile conditions (often pricked to bleed).
Modern Relevance & Mind-Body Connection
The TCM Lung's functions map beautifully onto modern understandings:
· The First Line of Defense: Its role in governing Wei Qi and the skin aligns with the immune system's mucosal and skin barriers.
· The Mind-Body Link: The association with grief is clinically observed. Chronic grief or sadness can deplete Lung Qi, leading to fatigue and low immunity. Conversely, Lung Qi deficiency can make one prone to sadness.
· The Breath & Nervous System: The act of deep breathing, governed by the Lung, is the most direct way to influence the autonomic nervous system, shifting from sympathetic (fight-or-flight) to parasympathetic (rest-and-digest) dominance. Acupuncture on the Lung channel often facilitates this shift.
In summary, the Lung Meridian in TCM is far more than an anatomical organ for respiration. It is the manager of vital energy, the guardian of the body's surface, the regulator of fluid metabolism, and the seat of somatic instinct and the processing of grief. To treat the Lung meridian is to treat a person's vitality, resilience, and their very connection to the world around them.
