Greater Yang Attack of Cold
Also known as: Taiyang Cold Damage Pattern, Wind-Cold Exterior Excess Pattern, Taiyang Exterior Excess (太阳表实证)
This pattern describes the earliest stage of an illness caused by exposure to cold, where the cold pathogen tightly constricts the body's surface, blocking the pores and preventing sweating. The person feels strongly chilled, develops fever, and experiences widespread body aches and stiffness in the head and neck. It is one of the most commonly encountered acute patterns in classical Chinese medicine, typically corresponding to the onset of a severe cold or flu caught after cold exposure.

What Makes It Better or Worse
Symptoms typically come on acutely after exposure to cold or wind-cold, often within hours. The Shang Han Lun notes that Greater Yang illness tends to resolve naturally around the shen-wei period (roughly 9am to 3pm), suggesting symptoms may ease during midday warmth and worsen in the evening and early morning when Yang Qi is naturally lower. If untreated, the pattern may persist for seven or more days before either resolving naturally or transforming into deeper-stage illness.
Practitioner's Notes
The key to recognising this pattern is the combination of strong chills, complete absence of sweating, generalised body pain, and a pulse that feels both floating (easily felt with light touch) and tight (like a vibrating cord). These four features together point unmistakably to cold that has tightly sealed the body's surface.
The diagnostic logic works like this: when cold invades the body's exterior, it causes the pores and skin to clamp shut. The body's defensive Qi (the force that protects the surface and regulates sweating) gets trapped beneath the skin, unable to push outward. This creates a backup of warmth and Qi internally, producing fever, while the blocked surface produces chills and the absence of any sweating. Because the cold constricts the channels running through the muscles and joints, the person aches all over. The Lungs, which are closely connected to the skin and breathing, also get affected, leading to laboured breathing or wheezing.
The single most important distinguishing feature is the absence of sweating. In a similar Greater Yang pattern called 'Greater Yang Wind Strike' (Taiyang Zhongfeng), the person sweats spontaneously and the pores are relatively loose. Here, the pores are sealed tight. This difference determines the entire treatment approach: this pattern requires strong sweating therapy to open the surface, whereas the Wind Strike pattern calls for gentle harmonising of the body's defences.
How a Practitioner Identifies This Pattern
In Traditional Chinese Medicine, diagnosis follows four methods of examination (Si Zhen 四诊), a framework developed over 2,000 years ago.
Inspection Wang Zhen 望诊
What the practitioner observes by looking at the patient
Tongue
Normal body, thin white moist coating
The tongue in this pattern is typically unremarkable in body colour and shape, reflecting the fact that the pathology is at the surface level and has not yet penetrated inward. The coating is thin, white, and moist (sometimes described as white and moist/润), consistent with cold at the exterior. If the coating appears dry or yellow, this suggests the pattern may already be transforming toward Heat, which would indicate a different stage of illness.
Listening & Smelling Wen Zhen 闻诊
What the practitioner hears and smells
Palpation Qie Zhen 切诊
What the practitioner feels by touch
Pulse
The hallmark pulse is floating and tight across all three positions (cun, guan, chi). The Shang Han Lun specifically states the pulse is 'yin and yang both tight' (脉阴阳俱紧), meaning the tight quality is present in both the superficial (yang/floating) and deeper levels, and across the full length of the pulse. The floating quality indicates the pathogen is at the surface and the body's defensive Qi is rising to fight it. The tight quality reflects cold constricting the channels and the defensive Qi being blocked. This pulse feels like a taut, vibrating cord that is easily felt with light pressure. If the chi (rear) position is weak or slow, it may indicate underlying Blood deficiency, in which case vigorous sweating therapy should be used cautiously.
How Is This Different From…
Expand each to see the distinguishing features
Both are Greater Yang exterior patterns with fever, chills, headache, and a floating pulse. The crucial difference is sweating: Greater Yang Wind Strike features spontaneous sweating with a floating and moderate (slow/relaxed) pulse, while Greater Yang Attack of Cold has no sweating with a floating and tight pulse. Wind Strike is considered an exterior deficiency pattern because the pores are open and leaking; Attack of Cold is exterior excess because the pores are sealed shut. Wind Strike is treated with Gui Zhi Tang (Cinnamon Twig Decoction) to harmonise the surface, while Attack of Cold requires Ma Huang Tang (Ephedra Decoction) to forcefully open the pores and induce sweating.
Wind-Cold Fettering the Lungs shares cough, nasal congestion, and aversion to cold, but the focus is primarily on respiratory symptoms (cough with thin white phlegm, nasal obstruction). Greater Yang Attack of Cold emphasises the whole-body picture of severe body aches, pronounced chills, and complete absence of sweating, with wheezing as a secondary feature. If cough and phlegm dominate and body aches are mild, Wind-Cold Fettering the Lungs is more appropriate.
View Wind-Heat entering the LungsWind-Cold-Damp (Bi Syndrome) also features body and joint pain with aversion to cold. However, Wind-Cold-Damp pain is chronic, migratory or fixed, and worsened by weather changes, while Greater Yang Attack of Cold is acute, with sudden onset of generalised aching, fever, and the hallmark absence of sweating. Wind-Cold-Damp does not typically present with the floating-tight pulse or acute febrile onset.
View Wind-Cold-DampWhen Greater Yang Attack of Cold occurs alongside pre-existing internal fluid retention, additional symptoms like watery vomiting, cough with copious thin clear phlegm, and difficulty breathing appear. This combined pattern is treated with Xiao Qing Long Tang (Minor Blue-Green Dragon Decoction) rather than simple Ma Huang Tang, because the internal fluids must be transformed simultaneously with releasing the exterior.
Core dysfunction
Cold invades the body's surface and seals the pores shut, trapping defensive Qi beneath the skin and disrupting the Lungs' ability to regulate the exterior, producing fever, chills, body aches, absence of sweating, and wheezing.
What Causes This Pattern
The factors that trigger or sustain this imbalance
Main Causes
The primary triggers for this pattern — expand each for a detailed explanation
This is the primary and defining cause of the pattern. When a person is exposed to cold weather, cold wind, or gets chilled (such as being caught in rain, working outdoors in winter, or sleeping in a cold draft), the Cold pathogen invades through the skin and muscles. In TCM, the body's surface is protected by Wei Qi (defensive Qi), which keeps the pores regulated and pathogens out. When Cold is strong enough or the body's defences are momentarily lowered, Cold breaks through this barrier.
Cold has a constricting, contracting nature. When it lodges in the skin and muscles, it tightens and closes the pores shut. This is why there is no sweating: the normal outward flow through the skin is blocked. The closure of the pores traps both the pathogen and the body's own defensive Qi beneath the surface, creating a 'pressure build-up' that manifests as body aches, joint pain, and stiffness. The body generates fever as it fights the invader, but because the surface is sealed shut, the heat cannot escape, leading to the characteristic combination of fever with strong chills.
Wind is described in TCM as the 'spearhead' of disease because it helps other pathogens penetrate the body's defences. In this pattern, Wind carries Cold through the body's exterior barrier. The Wind component accounts for the rapid onset and the headache, while Cold is the dominant pathogen responsible for the severity of chills, body aches, and pore closure. The Shang Han Lun classifies this under 'Shang Han' (Cold Attack) rather than 'Zhong Feng' (Wind Strike) because Cold predominates and the pores are tightly closed (no sweating).
While this pattern can strike anyone, it is more likely to take hold when the body's defences are temporarily lowered. Fatigue, lack of sleep, emotional stress, or being slightly run down can all reduce the strength of Wei Qi at the body's surface, creating an opening for Cold to invade. Similarly, a sudden transition from a warm environment to a cold one (such as leaving a heated room and stepping into freezing wind) can catch the body's defences off guard before they can adjust.
How This Pattern Develops
The sequence of events inside the body
To understand this pattern, it helps to know that TCM views the body's surface (skin, pores, and muscles just beneath the skin) as an active defensive layer, not just a passive barrier. This layer is maintained by Wei Qi (defensive Qi), a type of Qi that circulates at the surface, regulates the opening and closing of pores, warms the skin, and repels invading pathogens. The Lungs are the organ system responsible for distributing Wei Qi to the surface.
When a person is exposed to strong Cold (often carried by Wind), the Cold pathogen overwhelms the body's surface defences and lodges in the skin and muscle layer. Cold has a contracting, tightening nature: it clamps the pores shut and freezes the normal circulation of Qi and Blood in the superficial tissues. This produces the hallmark sign of no sweating: the pores are sealed. Because fluids and waste products that would normally be released through mild perspiration are now trapped, pressure builds up in the muscles and joints, causing the widespread body aches, joint pain, and stiffness that characterise this pattern.
Meanwhile, the body mounts a defensive response. It generates Heat (fever) as Wei Qi battles the Cold invader. But because the surface is locked down, this Heat cannot escape, and neither can the Cold be expelled. The result is a high fever paired with strong chills: the person feels very cold because Cold dominates the exterior, yet their body temperature rises as the defensive response intensifies. The Cold also disrupts the Lung's ability to disperse Qi outward and downward, which causes wheezing or shortness of breath. The headache, particularly at the back of the head and neck, occurs because the Tai Yang channel (Bladder channel) runs along this area and is the channel most directly affected by the invasion.
Five Element Context
How this pattern fits within the Five Element framework
Dynamics
This pattern primarily involves the Water element, as the Bladder (Tai Yang) is the Yang organ of the Water element pair (Kidney-Bladder). The Lungs (Metal element) are also significantly involved because they govern the skin and exterior. In Five Element terms, Metal is the 'mother' of Water. When the Lung's surface-regulating function is disrupted by Cold invasion, the Bladder channel (its 'child' in the generation cycle) is the first to be affected, which is why symptoms manifest along the Tai Yang Bladder channel running down the back of the body.
The goal of treatment
Release the exterior with acrid-warm herbs and promote sweating to expel Cold
TCM addresses this pattern through three complementary paths: herbal medicine, acupuncture and daily self-care. Each one works differently — and together they address this pattern from multiple angles.
How Herbal Medicine Helps
Herbal medicine is typically the backbone of TCM treatment. Formulas are precisely blended combinations of plants that work together to correct the specific imbalance underlying this pattern — targeting not just the symptoms, but the root cause.
Classical Formulas
These formulas are classically associated with this pattern — each selected because its properties directly address the core imbalance.
Ma Huang Tang
麻黄汤
The primary formula for this pattern. Contains Ma Huang, Gui Zhi, Xing Ren, and Zhi Gan Cao. It powerfully opens the exterior, promotes sweating, and restores Lung Qi descent to relieve wheezing. This is the representative formula from the Shang Han Lun for the Tai Yang Cold Attack (exterior excess) pattern.
Da Qing Long Tang
大青龙汤
Used when the Tai Yang Cold Attack pattern includes internal Heat with irritability and restlessness alongside the typical exterior Cold signs of fever, strong chills, body aches, and no sweating. It combines strong exterior-releasing with interior Heat-clearing.
Ge Gen Tang
葛根汤
Used when the Cold Attack pattern features especially pronounced stiffness and tightness in the neck and upper back. Ge Gen releases the muscles and generates fluids while the Ma Huang and Gui Zhi base addresses the exterior Cold.
Xiao Qing Long Tang
小青龙汤
Used when the exterior Cold Attack pattern co-exists with pre-existing internal fluid retention (Phlegm-Fluids). Key signs are exterior Cold symptoms plus profuse thin, watery, white phlegm, coughing, and wheezing.
How Practitioners Personalise These Formulas
TCM treatment is rarely one-size-fits-all. Based on the individual's full presentation, practitioners often adapt these base formulas:
If there is pronounced stiffness and pain in the neck and upper back: Add Ge Gen (Kudzu Root) to the base Ma Huang Tang formula. Ge Gen releases the muscles of the Tai Yang channel and generates fluids, addressing the tight constriction that Cold causes in the upper back and nape region.
If there is also restlessness, irritability, or internal Heat: Switch from Ma Huang Tang to Da Qing Long Tang, which adds Shi Gao (Gypsum), Sheng Jiang, and Da Zao to clear the internal Heat while still releasing the exterior. This is appropriate when the person has strong chills and no sweating but also feels agitated and restless.
If there is also coughing with profuse thin, watery phlegm: Switch to Xiao Qing Long Tang, which combines the exterior-releasing strategy with herbs that warm and transform internal fluid accumulation (such as Ban Xia, Gan Jiang, Xi Xin, and Wu Wei Zi).
If the condition has lingered for several days with only partial resolution: Use the milder Gui Zhi Ma Huang Ge Ban Tang (a combined half-dose of both formulas) to gently release the remaining exterior pathogen without over-sweating.
If the person also has underlying Yang deficiency (feels cold even before getting sick, very fatigued, with a deep pulse): Consider Ma Huang Fu Zi Xi Xin Tang, which combines exterior-releasing with interior Yang-warming using Fu Zi and Xi Xin. This addresses the Tai Yang-Shao Yin combined pattern.
Key Individual Herbs
Beyond full formulas, certain individual herbs are particularly well-suited to this pattern — each carrying properties that speak directly to the underlying imbalance.
Ma Huang
Ephedra
The primary herb for this pattern. Acrid and warm, it powerfully opens the pores and promotes sweating to expel exterior Cold. It also restores the descending and dispersing function of the Lungs to relieve wheezing.
Gui Zhi
Cinnamon twigs
Warms the channels and assists Ma Huang in releasing the exterior. It promotes the outward movement of Yang Qi to push the Cold pathogen out through the skin.
Xing Ren
Apricot seeds
Directs Lung Qi downward to relieve coughing and wheezing. Its descending action complements Ma Huang's dispersing action, creating a balanced regulation of Lung Qi.
Gan Cao
Liquorice
Harmonizes the formula, moderates the strong dispersing actions of Ma Huang and Gui Zhi to prevent excessive sweating, and protects the Stomach.
Ge Gen
Kudzu roots
Used when there is pronounced stiffness and pain in the upper back and neck. It releases the muscle layer and generates fluids, making it useful when Cold tightly binds the Tai Yang channel.
Sheng Jiang
Fresh ginger
Fresh ginger warms the Stomach and assists in dispersing exterior Cold. It is added when nausea or vomiting accompanies the exterior pattern.
How Acupuncture Helps
Acupuncture works by stimulating specific points along the body's energy channels to restore flow and balance. For this pattern, treatment targets the channels most involved in the underlying dysfunction — signalling the body to rebalance from within.
Primary Points
These points are classically selected for this pattern. Each one influences specific organs, channels, or functions relevant to restoring balance.
LU-7
Lieque LU-7
Liè quē
The Luo-connecting point of the Lung channel and confluent point of the Ren Mai. It releases the exterior, disperses Wind-Cold, and restores the Lung's dispersing function. A key point for any exterior Cold pattern affecting the Lungs.
LI-4
Hegu LI-4
Hé Gǔ
The Yuan-source point of the Large Intestine channel. It powerfully promotes sweating and releases the exterior. Combined with LU-7, it forms a classic pair for expelling exterior pathogens.
BL-12
Fengmen BL-12
Fēng Mén
The 'Wind Gate' point on the Bladder channel. It directly expels Wind-Cold from the Tai Yang level and is located in the upper back region where this pattern's stiffness and pain concentrate.
GB-20
Fengchi GB-20
Fēng Chí
Located at the base of the skull, it expels Wind and releases the exterior. Particularly useful for the occipital headache and neck stiffness characteristic of this pattern.
DU-14
Dazhui DU-14
Dà Chuí
The meeting point of all Yang channels. It strongly releases the exterior, expels Cold, and regulates defensive Qi. Effective for fever and chills in exterior patterns.
BL-13
Feishu BL-13
Fèi Shū
The Back-Shu point of the Lungs. It restores the Lung's dispersing and descending functions, helping relieve wheezing and cough that accompany this pattern.
Acupuncture Treatment Notes
Guidance on needling technique, point combinations, and session structure specific to this pattern:
Point combination rationale: The core strategy pairs LU-7 (Lieque) with LI-4 (Hegu) to open the exterior and promote sweating. These are Lung and Large Intestine channel points respectively, forming an interior-exterior channel pair that strongly mobilises Wei Qi to the surface. BL-12 (Fengmen) and BL-13 (Feishu) are added to directly address the Tai Yang channel where the pathogen lodges, and to restore Lung Qi dispersal for wheezing. DU-14 (Dazhui) reinforces Yang Qi at the confluence of all Yang channels and is particularly effective for reducing fever and chills.
Technique: Use reducing (xie) method on all points. Needles should be retained for only 10-15 minutes, as this is an acute exterior condition. Moxibustion may be applied at BL-12 and DU-14 to warm the channels and help expel Cold. Cupping on the upper back (BL-12, BL-13 region) is a widely used adjunct that effectively disperses Cold from the Tai Yang channel.
Gua Sha: Scraping along the Bladder channel on the upper back is a highly effective physical technique for this pattern. It opens the surface, promotes sweating, and quickly relieves muscle aches and stiffness.
Caution: Once sweating begins, stop treatment. Over-stimulation in an exterior condition can cause excessive sweating, which damages Qi and fluids. The classical instruction from the Shang Han Lun is to aim for a light, moist sweat over the whole body, not drenching perspiration.
What You Can Do at Home
Professional treatment works best when supported by daily habits. These recommendations are drawn directly from the TCM understanding of this pattern — they address the same root imbalance from a different angle, and can meaningfully accelerate recovery.
Diet
Foods that support your body's recovery from this specific imbalance
Warm, easily digestible foods are essential during this pattern. The goal is to support the body's effort to push the Cold pathogen out through the surface. Hot soups and congees are ideal. Plain rice congee with sliced fresh ginger and scallion (spring onion) whites is a traditional home remedy that gently warms the interior and encourages mild sweating. Hot water with fresh ginger and a small amount of brown sugar can also help.
Avoid cold, raw, and chilled foods and drinks. Cold foods like salads, ice cream, cold smoothies, and iced water directly reinforce the Cold pathogen and make it harder for the body to warm up and open the pores. Dairy products and greasy foods should also be avoided temporarily, as they can produce Dampness and Phlegm that complicate the pattern, especially if there is already coughing or wheezing.
Eat lightly. During an acute exterior attack, digestion is naturally weaker because the body's resources are focused on fighting the pathogen at the surface. Small, frequent meals of warm, bland food are better than large heavy meals. This is why the Shang Han Lun advises sipping hot rice porridge after taking Ma Huang Tang to support the Stomach and encourage gentle sweating.
Lifestyle
Daily habits that help restore balance — small changes that compound over time
Stay warm and rest. During an acute attack of this pattern, the single most important thing is to keep the body warm so it can generate the sweating needed to expel the Cold. Dress in warm layers, stay under blankets, and avoid going outside into cold or windy conditions. Rest is essential because the body needs all its resources directed toward fighting the pathogen.
Encourage gentle sweating. A warm bath, a hot foot soak, or drinking warm ginger tea under a blanket can help the body begin to sweat lightly and push the Cold out. The key is gentle, all-over perspiration, not drenching sweats. Once you begin to sweat lightly and feel relief, change into dry clothes and continue resting.
After recovery, protect yourself from re-invasion. The body's defences are temporarily weakened after an exterior attack. For several days after symptoms resolve, continue to dress warmly, avoid cold drafts and air conditioning, and do not overexert yourself. Eating warm, nourishing foods during recovery helps rebuild the defensive Qi at the surface.
Qigong & Movement
Exercises traditionally recommended to move Qi and support recovery in this pattern
During the acute phase: Active exercise is not recommended. The body's resources should be directed toward fighting the pathogen, not expended on physical activity. Rest is the priority.
During recovery: Once fever and chills have resolved and the person feels stronger, gentle movement helps restore the flow of Wei Qi at the surface. Ba Duan Jin (Eight Brocade Exercises) performed slowly and gently for 10-15 minutes is an excellent recovery practice. The first movement, 'Two Hands Hold Up the Heavens', gently stretches the San Jiao and helps circulate Qi throughout the body. The second movement, 'Drawing the Bow', opens the chest and benefits the Lungs.
For ongoing prevention: Regular practice of Ba Duan Jin or Tai Chi (20-30 minutes, 3-5 times per week) strengthens Wei Qi and improves the body's resilience against future Cold invasions. Cold-water face washing in the morning (gradually introduced) can also train the body's surface defences to respond more quickly to temperature changes.
If Left Untreated
Like many TCM patterns, this one tends to deepen and compound over time. Here's what may happen if it goes unaddressed:
If this pattern is not addressed promptly, several transformations may occur depending on the person's constitution and the strength of the pathogen:
Inward transmission to the Yang Ming stage: The trapped exterior Cold may transform into interior Heat as the body's Yang Qi continues to fight the pathogen. The chills disappear and are replaced by high fever without chills, sweating, intense thirst, and constipation. This is a deeper, hotter stage of illness that requires a completely different treatment approach.
Progression to the Shao Yang stage: If the body's defences are insufficient to either fully expel or fully contain the pathogen, it may settle in a 'half-interior, half-exterior' position. This produces alternating chills and fever, a bitter taste in the mouth, and nausea.
Collapse into Shao Yin: In people with underlying Yang deficiency, the Cold pathogen may move deeper to affect the Kidney and Heart Yang. This produces extreme fatigue, desire to sleep, cold limbs, and a faint pulse. This is a serious deterioration requiring urgent warming treatment.
Lingering exterior pattern: If the pattern is partially treated (for example, with insufficient sweating), it may linger as a low-grade, unresolved exterior condition with persistent mild chills, slight fever, and body aches that drag on for days or weeks.

Constitutional tendency
People who tend to develop this pattern often share these constitutional traits: People who are physically robust and active tend to develop this particular excess-type pattern when catching cold, because their strong defensive Qi puts up a vigorous fight against the invading Cold, producing the characteristic high fever and strong body aches. However, anyone exposed to sufficient cold can develop this pattern. People who tend to feel cold, have low energy, or sweat easily are more likely to develop the milder Wind-Strike (Zhong Feng) form instead, or may quickly progress to deeper stages of illness.
What Western Medicine Calls This
These are the biomedical diagnoses most commonly associated with this TCM pattern — useful if you're bridging Eastern and Western healthcare.
Practitioner Insights
Key observations that experienced TCM practitioners use to identify and understand this pattern — details that go beyond the textbook.
The cardinal diagnostic distinction is absence of sweating. This is the single most critical differentiating feature from the Greater Yang Wind-Strike (Zhong Feng) pattern, which presents with spontaneous sweating and a moderate-floating pulse. The Shang Han Lun is unambiguous: sweating means Gui Zhi Tang; no sweating means Ma Huang Tang. Mixing these up can worsen the condition.
The 'eight symptoms' of Ma Huang Tang: Classical commentators including Liu Dujou refer to the eight symptoms listed in Clause 35 as 'Ma Huang Ba Zheng' (麻黄八证): headache, fever, body pain, low back pain, joint pain, aversion to cold/wind, absence of sweating, and wheezing. Not all eight need to be present simultaneously. The key triad is: aversion to cold + no sweating + floating tight pulse.
Pulse diagnosis is paramount. The pulse must be floating AND tight (浮紧). A floating-moderate pulse points to Wind-Strike. If the chi (cubit) position is slow or weak, indicating Blood or Yin deficiency, sweating methods are contraindicated even if surface symptoms suggest this pattern (Clause 50 of the Shang Han Lun).
Do not over-sweat. The Shang Han Lun repeatedly warns against excessive sweating. The goal is 'wei si han' (微似汗), a light dampness across the body. Profuse sweating damages Qi and fluids and can cause serious complications including palpitations, muscle spasms, and collapse of Yang. After taking Ma Huang Tang, the patient should be covered warmly but monitored. Once light sweating appears, stop further doses.
Self-resolution through epistaxis (nosebleed): Clauses 46-47 describe cases where the pattern resolves spontaneously through nosebleed (衄解). This occurs because when sweat cannot exit, the body may expel the trapped heat through bleeding from the nose (the Lung's orifice, closest to the Tai Yang). A small epistaxis followed by relief of symptoms and settling of fever should not be cause for alarm. It is a natural resolution mechanism reflecting the classical principle that 'sweat and blood share the same source.'
Time-sensitivity: This is an acute, time-limited pattern. The natural disease course described in the Shang Han Lun is approximately 7 days. If untreated beyond this period, the pattern rarely stays static. It transforms: into Yang Ming (Heat), Shao Yang (half-interior), or if Yang is weak, into Shao Yin (Cold collapse). Always assess for signs of transformation at follow-up.
How This Pattern Fits Into the Bigger Picture
TCM patterns don't exist in isolation. Understanding where this pattern comes from — and where it can lead — gives you a clearer picture of your health journey.
These patterns commonly evolve into this one — they can be thought of as earlier stages of the same underlying imbalance:
These patterns frequently appear alongside this one — many people experience more than one pattern of disharmony at the same time:
When Cold attacks the Tai Yang level, the Lungs are often simultaneously affected because they govern the skin and exterior. This produces additional coughing, nasal congestion, and sneezing alongside the Tai Yang Cold Attack symptoms.
People with pre-existing internal fluid retention may develop coughing with profuse thin, watery phlegm when Cold attacks the exterior. The classical Shang Han Lun addresses this combination with Xiao Qing Long Tang.
How TCM Classifies This Pattern
TCM has developed multiple overlapping frameworks for categorising patterns of disharmony. Each lens reveals something different about the nature and location of the imbalance.
Eight Principles

Six Stages

Related TCM Concepts
Broader TCM theories and concepts that deepen understanding of this pattern — useful for those wanting to go further in their study of Chinese medicine.
The Greater Yang (Tai Yang) stage is the first and outermost of the Six Stages described in the Shang Han Lun. This pattern represents the excess (Shang Han) variant of Tai Yang disease.
The Lungs govern the skin and control the opening and closing of pores. When Cold invades, it disrupts the Lung's dispersing function, causing wheezing and inability to sweat.
The Bladder channel (Tai Yang) runs along the entire back of the body from the head to the feet. It is the first line of defence and the channel most directly affected in this pattern.
Wei Qi (defensive Qi) circulates at the body's surface to protect against invasion. This pattern arises when Cold overwhelms Wei Qi and blocks its normal circulation.
Classical Sources
References to the foundational texts of Chinese medicine where this pattern, or its underlying principles, are discussed. These are the sources that practitioners and scholars have studied for centuries.
Shang Han Lun (伤寒论), Clause 3: 'Tai Yang disease, whether fever has already appeared or not, there must be aversion to cold, body pain, vomiting, and a pulse that is tight in both the cun and chi positions: this is called Shang Han (Cold Attack).' This clause establishes the diagnostic criteria for the Cold Attack pattern within the Tai Yang stage, distinguishing it from the Wind-Strike pattern.
Shang Han Lun, Clause 35: 'In Tai Yang disease, with headache, fever, body pain, low back pain, joint pain, aversion to wind, absence of sweating and wheezing: Ma Huang Tang governs.' This is the definitive clause linking the full symptom picture to its treatment formula.
Shang Han Lun, Clause 46: Describes the case of a Cold Attack that has persisted for 8-9 days without resolution. Even though the natural disease course has been exceeded, if the exterior signs remain, Ma Huang Tang is still indicated. This clause also describes the phenomenon of resolution through epistaxis (nosebleed).
Shang Han Lun, Clause 51: 'When the pulse is floating, the disease is at the exterior and sweating may be used. Ma Huang Tang is appropriate.' A concise statement of the principle linking floating pulse to exterior disease and the sweating method.
