The Lung Meridian begins the daily cycle of energy circulation through the twelve primary meridians — making it, in a sense, the starting point of life itself. In Traditional Chinese Medicine, the Lungs are not just bellows for oxygen exchange. They are the organ most intimately connected to the outside world: every breath is an act of opening the boundary between self and environment, taking in what nourishes and releasing what no longer serves. This rhythm of taking in and letting go governs not only respiration but also the body’s relationship with grief, loss, and the skin that separates us from the world.
The Lung in Traditional Chinese Medicine
In the five-element framework of TCM, the Lung belongs to the Metal element — the element of autumn, refinement, clarity, and the capacity to distil what is essential from what is not. Metal is the element that knows what has value and what can be released: the ore extracted from the rock, the pure from the dross. Its season is autumn — the time of harvest, of leaves falling, of letting go before winter’s inward turn. Its color is white. Its emotion is grief.
The Lung’s Yang partner is the Large Intestine — an organ that, in TCM, shares the Metal element’s function of releasing and eliminating what the body no longer needs. Together, they govern the body’s capacity to take in, extract what is valuable, and release the rest — whether that is oxygen and carbon dioxide, nutrients and waste, or experiences and emotions.
The Lung’s two core functions in TCM are:
- Descending and dispersing Qi — the Lungs receive the “pure Qi” from the air, combine it with the Grain Qi from the Spleen, and distribute the resulting gathering Qi (Zong Qi) downward and outward to the entire body
- Governing the skin and pores — the Lungs control the opening and closing of the skin’s pores, regulate sweating, and govern the body’s first defensive boundary against external pathogens
The Lung is most active between 3am and 5am — the earliest hours of the morning, just before dawn. This is the hour when the body’s energy transitions from the deep Yin of night toward the rising Yang of day. People who consistently wake at this time, or who experience respiratory symptoms in these hours, often have Lung Qi or Lung Yin deficiency patterns in TCM.
The Pathway of the Lung Meridian
The Lung Meridian (Shou Tai Yin — Hand Greater Yin) is one of the shorter primary meridians, with 11 points running from the chest to the thumb.
Its pathway:
- Begins internally in the middle burner (stomach region), descends to connect with the large intestine, then ascends through the diaphragm to the lungs
- Surfaces at the chest at Lung 1 (Zhongfu) — the Front Collecting (Mu) point of the Lung, located below the outer collarbone
- Ascends briefly to the shoulder and then descends along the inner (medial) surface of the upper arm
- Passes through the elbow crease at Lung 5 (Chize)
- Continues along the inner forearm on the thumb side
- Crosses the wrist at Lung 7 (Lieque) and Lung 9 (Taiyuan)
- Runs along the thenar eminence (the fleshy mound at the base of the thumb)
- Ends at the outer corner of the thumbnail at Lung 11 (Shaoshang)
What the Lung Meridian Governs
- Respiration and Qi intake — the primary function; the Lungs govern the breath and the extraction of pure Qi from air
- Distribution of Wei Qi — the defensive Qi that circulates at the body’s surface, protecting against external pathogens; Lung deficiency leads to frequent colds and lowered immunity
- The skin and body hair — the Lung “opens to the skin”; skin conditions, excessive or insufficient sweating, and dry skin all reflect Lung function
- The nose — the Lung “opens to the nose”; nasal congestion, loss of smell, rhinitis, and sinusitis are often Lung meridian conditions
- The voice — the quality and strength of the voice reflects Lung Qi; a weak, thin, or breathless voice often indicates Lung Qi deficiency
- Grief and letting go — the Lung’s associated emotion; unresolved grief, difficulty letting go, and holding on to what has passed are the primary emotional disruptions of Lung Qi
- The Po — the Corporeal Soul — the Lung’s spiritual aspect; the Po is the instinctual, body-bound aspect of the spirit that governs sensation, physical vitality, and the capacity to be fully present in the body
Grief, Loss, and the Emotional Dimension
The Lung’s associated emotion is grief — understood broadly as sadness, loss, the ache of separation, and the difficulty of letting go. In TCM, grief is not pathological in itself: it is the appropriate emotional response to loss, and a Lung that is functioning well can feel grief fully, process it, and eventually release it. The pathology arises when grief becomes stuck — when the Lung cannot complete its natural movement of taking in, extracting what is nourishing, and releasing what is no longer needed.
Unresolved grief settles in the Lung in TCM — often literally: many people find that periods of bereavement or significant loss are accompanied by respiratory symptoms, increased susceptibility to colds, a quality of breathlessness or shallow breathing, or a heaviness in the chest that has no clear physical cause. The body is holding what the heart has not yet been able to release.
The healthy expression of Metal element energy is the capacity for discernment and release — knowing what is truly valuable and worth keeping, and having the courage to let go of what is not. This applies to relationships, beliefs, habits, and emotions alike. The autumn energy of the Lung is not mournful — it is clear, refined, and deeply present, like the quality of autumn air itself: crystalline, precise, with a particular kind of beauty that comes from knowing that things pass.
Signs of Lung Meridian Imbalance
Lung Qi Deficiency
- Frequent colds, flu, or respiratory infections — the Wei Qi is weak
- A weak, breathless, or thin voice
- Fatigue — particularly in the early morning (3–5am)
- Spontaneous sweating without exertion
- Pale complexion
- Low energy and reluctance to speak
Lung Yin Deficiency
- Dry cough — often worse at night or in the early morning
- Dry throat, mouth, and skin
- Night sweats
- A low-grade fever or sensation of heat in the afternoon
- Hoarse voice
Wind-Cold or Wind-Heat Invading the Lungs
- Acute onset of cold or flu symptoms — chills, fever, nasal congestion, cough
- Sore throat and body aches
- Stiff neck and upper back
Key Acupuncture Points on the Lung Meridian
Lung 7 — Lieque (Broken Sequence)
Located about 1.5 cun (two finger-widths) proximal to the wrist crease on the radial (thumb) side of the inner forearm, in a small depression just above the styloid process of the radius — not on the crease itself (that is LU9). This is one of the most important points on the Lung Meridian — the Luo-Connecting point and the opening (confluent) point of the Ren Mai (Conception Vessel). In TCM it is used to open the chest, support the processing of grief, and release external Wind in the early stage of a cold. Pressing this point during chest tightness, the onset of a cold, or moments of emotional constriction is a traditional self-care practice; any opening effect varies from person to person.
Lung 9 — Taiyuan (Great Abyss)
Located at the wrist crease, on the radial side, lateral to the radial artery — the point where the pulse is taken in classical Chinese medicine. This is the source point and the Earth point of the Lung Meridian, and the Influential Point of the Vessels — meaning it influences the entire vascular system. It is used for Lung Qi and Yin deficiency, chronic cough, weak voice, and dry throat. Its influence on the pulse and vessels makes it one of the most tonifying points on the meridian.
Lung 5 — Chize (Cubit Marsh)
Located at the elbow crease, on the radial side of the biceps tendon. This is the Water point of the Metal meridian — particularly effective for clearing Heat from the Lungs: cough with yellow phlegm, sore throat with fever, and asthma with a hot quality. It also treats elbow pain and the inner arm along the meridian pathway. When the Lung is inflamed or hot — acute bronchitis, fever with cough — LU5 is the primary point.
Lung 1 — Zhongfu (Middle Palace)
Located on the chest in the first intercostal space, about 6 cun lateral to the midline (roughly a hand-width out from the centre, below the outer collarbone). This is the Front Collecting (Mu) point of the Lung — it directly reflects and influences the lung organ in TCM. Tenderness here is diagnostically significant in that framework: acute tenderness often indicates a Lung excess pattern; a more chronic, dull ache reflects deficiency. Gently pressing both LU1 points simultaneously while taking several slow, deep breaths is a traditional way to open the chest. Use finger pressure only — this point sits over the apex of the lung and is not a site for deep needling at home.
Daily Practices to Support the Lung Meridian
1. The Complete Breath — Nourishing the Lung Daily
The most fundamental practice for the Lung Meridian is also the most obvious: breathing fully and consciously. Most people in modern life breathe shallowly — using only the upper chest, rarely engaging the full respiratory system. The Lung cannot distribute Qi effectively if the breath is consistently shallow.
Practice: Sit comfortably with the spine tall. Place one hand on the chest and one on the belly. Inhale slowly through the nose for a count of four — feel the belly expand first, then the chest rise. Hold for two counts. Exhale through the nose for a count of six — feel the chest fall first, then the belly draw gently inward. Pause for two counts before the next inhale. Practice 10–15 complete breath cycles each morning. Done consistently, this is the most direct daily support for the Lung in TCM — no supplement required.
2. Press LU7 for Chest and Grief Release
Find the point about two finger-widths above the wrist crease on the thumb side of the inner forearm — feel for a small notch just above the bony bump of the radius. Press firmly with the thumb of the opposite hand for 2–3 minutes per wrist. This point can be pressed during chest tightness, at the onset of a cold, or during moments when grief or sadness feels held in the chest. Some people notice a deepening of the breath within the first minute of sustained pressure.
3. The Grief Practice — Completing What Is Unfinished
Because unresolved grief is the primary emotional burden of the Lung, one of the most important practices for this meridian is creating space to feel and process loss — not as self-indulgence, but as a genuinely physical act of supporting Lung function.
This might look like: setting aside ten minutes to sit with a loss that has not yet been fully felt; writing a letter to someone or something you have lost and cannot recover; allowing yourself to cry without cutting it short; or simply sitting quietly with the awareness of what has passed and letting the breath deepen naturally in response.
In TCM, crying is the Lung’s natural release valve — the equivalent of the Liver’s sighing. Allowing tears is not weakness; it is the Metal element doing precisely what it is designed to do: releasing what it has held, so the Lung can return to the clarity and openness of its natural state.
4. Protect Against Wind and Cold
The Lung is the most vulnerable of all organs to external pathogenic factors in TCM — particularly Wind, Cold, and Dryness. The back of the neck (where BL10 and GB20 are located) is considered the primary entry point for Wind invasion. Keeping the neck covered in cold or windy weather, avoiding cold drafts, and wearing appropriate clothing during seasonal transitions are genuinely protective for Lung Qi.
In autumn — the Lung’s season — pay particular attention: transition to warmer clothing earlier than feels strictly necessary, and be especially diligent about keeping the neck and upper back covered during wind exposure.
5. Lung-Nourishing Foods
The Lung is associated with the pungent/spicy flavor in moderation, the color white, and moistening, clarifying foods:
- Pears — the classic Lung-nourishing fruit in TCM; moistening for Lung Yin deficiency, particularly effective for dry cough
- White foods — daikon radish, white mushrooms, lotus root, lily bulb; all associated with the Metal element and Lung nourishment
- Honey — moistening and soothing for the Lung; particularly in warm water or herbal tea
- Ginger — warming and dispersing; used for Wind-Cold invasion (early cold with chills)
- Almonds — nourish Lung Yin and are used in TCM herbal formulas for dry cough
6. Chest-Opening Movement
The Lung Meridian runs along the inner arm and across the chest — and the modern posture of rounded shoulders and collapsed chest directly compresses its pathway. Daily practices that open the chest, externally rotate the arms, and expand the front of the body support Lung Qi circulation.
Simple practices: stand in a doorway with arms raised to shoulder height, forearms resting on the frame, and gently lean forward to stretch the chest and inner arms. Or: clasp hands behind the back, straighten the arms, and lift them slightly while drawing the shoulder blades together and lifting the sternum. Hold each position for 30–60 seconds, breathing fully into the expanded chest.
Final Thoughts: The First Breath and the Last
The Lung Meridian begins the daily energy cycle and governs the most fundamental act of life: breathing. But its wisdom runs deeper than respiration — it is the organ that knows how to grieve, how to release, and how to meet the world with open arms while maintaining the discerning boundary that keeps the self intact.
Breathe fully each morning. Press LU7 when the chest feels tight. Let yourself grieve what deserves to be grieved. Keep the neck warm. Eat pears in autumn. These are the Lung’s simple, profound invitations — to take in what nourishes, and to let go of everything else.
