Lung Heat

Lung Heat represents pathogenic heat accumulating in the Lung system, disrupting its descending and dispersing functions. This pattern commonly arises from external heat invasion, prolonged emotional stress generating internal heat, or dietary irregularities producing heat that ascends to impair Lung qi. Clinically significant as it can progress to more severe conditions including Lung yin deficiency or phlegm-heat obstruction.

Clinical Presentation

Cough with yellow, thick sputum or dry cough
Fever, often with afternoon aggravation
Thirst with preference for cold drinks
Restlessness and irritability
Chest oppression or pain
Shortness of breath
Nasal congestion with yellow discharge
Sore throat
Constipation
Dark yellow urine
Tongue: Red with yellow coating
Pulse: Rapid and floating, or rapid and slippery

Pattern Differentiation

vs. Lung Dryness

Lung Heat presents with yellow, thick sputum and strong thirst for cold drinks, while Lung Dryness shows scanty, sticky sputum or dry cough with mild thirst. Lung Heat tongue is red with yellow coating versus Lung Dryness showing red tongue with little coating. Lung Heat has rapid, strong pulse compared to the fine, rapid pulse of Lung Dryness.

vs. Wind-Heat Attacking Lungs

Wind-Heat shows sudden onset with pronounced exterior symptoms like headache, aversion to wind, and floating pulse. Lung Heat develops gradually with internal heat signs predominating over exterior symptoms. Wind-Heat typically resolves within days while Lung Heat persists without proper treatment. Lung Heat presents stronger thirst and more pronounced yellow sputum.

vs. Phlegm-Heat Obstructing Lungs

Phlegm-Heat shows copious yellow-green sputum that is easily expectorated, while Lung Heat has thick yellow sputum that is difficult to expectorate. Phlegm-Heat presents with chest fullness and rattling sounds, whereas Lung Heat shows chest oppression without obvious phlegm sounds. Phlegm-Heat pulse is slippery and rapid versus the floating-rapid pulse of pure Lung Heat.

Treatment Principle

Clear heat from the Lungs, restore descending and dispersing functions of Lung qi, resolve phlegm if present, and nourish Lung yin if heat has begun to consume fluids.

Frequently Asked Questions

Transformation typically occurs after 2-3 weeks of persistent heat if inadequately treated. Monitor for decreasing sputum volume, night sweats, and pulse changing from rapid-floating to rapid-fine. Early intervention with yin-nourishing herbs prevents this progression.

Clear heat first while gently supporting qi. Use moderate heat-clearing herbs like Sang Ye and Ju Hua rather than bitter-cold herbs that further damage qi. Add small amounts of qi-tonifying herbs like Tai Zi Shen once acute heat symptoms subside.

Eliminate warming foods including alcohol, spicy foods, and excessive meat. Recommend pears, water chestnuts, lotus root, and chrysanthemum tea. Patients should avoid cold dairy which produces phlegm, despite the heat condition requiring cooling foods.

External invasion shows recent onset with mild exterior symptoms and floating pulse qualities. Internal generation presents gradual onset, stronger internal heat signs like marked thirst and constipation, and deeper pulse positions. Treatment approach differs significantly based on this distinction.
