Wind-Heat invading the Lungs

Understanding Wind-Heat invading the Lungs

Wind-Heat begins at the surface. When it is not released, it is said to move inward to the Lungs, which govern Qi and the airways, and the cough becomes the leading symptom.

The cough is usually dry at first and then produces yellow or sticky phlegm. The throat remains sore, the fever persists with mild chills, and there may be thirst and a slight sweat.

The tongue shows the Heat at the tip with a thin yellow coat, and the pulse is floating and rapid. The floating quality is the marker that the pathogen is still at the exterior, which is why releasing is still part of the treatment.

The Lungs are described as delicate and as the first organ an external pathogen meets, which is why respiratory symptoms follow so closely on a Wind-Heat invasion.

Treatment releases the remaining exterior and clears Lung Heat at the same time. If the cough produces thick yellow phlegm and the pulse is no longer floating, the pattern has become Lung Heat and is treated differently.

Signs and symptoms

Key signs

• Cough
• Fever with mild chills
• Sore throat
• Floating and rapid pulse

Also seen

• Yellow or sticky phlegm
• A dry throat and thirst
• Slight sweating
• Headache
• A hoarse voice
• A blocked or runny nose with yellow discharge

Variations

• Chest tightness with the cough
• A cough that is worse at night
• Swollen tender glands in the neck

Timing

• It follows a Wind-Heat invasion within a day or two and usually settles within a week.
• The cough often outlasts the fever.

Practitioner notes

• The tongue is slightly red with a red tip and a thin yellow coat. A thick greasy coat would point to Damp-Heat instead.
• The pulse is floating and rapid. A pulse that has become deep indicates the pathogen has moved inward.
• The distinction from Wind-Heat at the surface is that the cough now dominates over the general surface symptoms.
• The distinction from Lung Heat is the floating pulse: once it is no longer floating, releasing the exterior is no longer the main task.

Causes

Common causes

• Invasion of external Wind-Heat
• Wind-Cold transforming into Wind-Heat
• Seasonal and environmental factors
• Pre-existing Yin deficiency or weakened defensive Qi

How it develops

• It develops from Wind-Heat that was not released, or from Wind-Cold that transformed.
• If it deepens, it becomes Lung Heat with thick yellow phlegm and a deep pulse.

Diagnosis

Diagnosis rests on the cough plus the surface signs: floating rapid pulse and a red tongue tip.

Tongue

• Body: Slightly red, with a red tip.
• Coating: Thin yellow.
• Note: A white coat would point to Wind-Cold.

Pulse

Floating, Rapid

Floating shows the exterior component; rapid shows the Heat.

Observation

• A flushed face
• A slight sweat
• A cough that catches attention

Listening

• A clear, frequent cough
• A hoarse voice

Palpation

• Abdomen: Unremarkable.
• Channels: The skin may be warm; LU-5 and DU-14 may feel hot.

Questions that separate it from look-alikes

• Is the cough dry or productive, and what colour is the phlegm?
• Is there fever, and are there chills?
• How is the throat?
• How long has it been going on?

Treatment

Principles

• Release Wind-Heat from the exterior
• Clear Lung Heat
• Stop the cough
• Benefit the throat

Herbs

Formulas

• Yin Qiao San - The reference formula for Wind-Heat, used when the throat and surface symptoms dominate.
• Sang Ju Yin - The formula for Wind-Heat with cough, built on mulberry leaf and chrysanthemum.
• Ma Xing Shi Gan Tang - Used when the pattern has deepened into Lung Heat with cough and yellow phlegm.

Acupoints

• LI-11 (Quchi) - Clears Heat from the surface and the Lungs.
• DU-14 (Dazhui) - Clears Heat and releases the exterior.
• BL-13 (Feishu) - The Lung back-shu point, used for cough and Lung patterns.
• LU-11 (Shaoshang) - A point for clearing Heat from the throat.
• GB-20 (Fengchi) - The Wind point, used for headache and wind sensitivity.

Personalising the plan

• If the cough dominates, Lung-clearing and descending herbs are increased.
• If the throat dominates, throat-specific herbs are increased.
• If phlegm turns thick and yellow, stronger Heat-clearing herbs are added.
• If the person is depleted, releasing is kept gentle.

Self-care

Diet

• Light, cooling food; pear and warm water
• Avoid spicy, fried and greasy food
• Avoid very cold drinks
• Small frequent meals

Lifestyle

• Rest, and keep the room ventilated but not draughty
• Avoid smoky environments
• Rest the voice
• Sleep with the head slightly raised if the cough is nocturnal

Qigong and movement

• Not during the acute phase; resume gently after the fever settles.

How it differs from look-alikes

Patterns that can be mistaken for wind-heat invading the lungs, and the contrast that separates them.

Where it appears

Skin conditions in which this pattern is commonly seen.

Safety and when to get help

For anything severe, sudden or spreading quickly, read when a skin problem needs urgent care.

This page describes a TCM pattern, not a diagnosis, and a pattern can accompany more than one skin condition. Get urgent medical help for a rash with fever, confusion or feeling very unwell; skin that is blistering, peeling or spreading quickly; swelling of the face, lips or throat, or difficulty breathing; or a lesion with increasing pain, warmth, red streaks or pus. For anything persistent, severe or changing, have it assessed by a clinician before treating it yourself.

Read the skin condition pages for the red flags that belong to a specific presentation.

Urgent-sign guidance is based on standard sources: NHS anaphylaxis, NHS cellulitis, NHS Stevens-Johnson syndrome, NHS melanoma.

Evidence note

No controlled trial of this treatment in skin conditions was identified for this entry. What is described here rests on the classical and later materia medica record and on traditional clinical use, not on controlled trial evidence, and it is not a prediction of benefit. Where skin-specific research does exist it is linked above.
