About This Formula
Traditional Chinese Medicine background and properties
Formula Description
A classical formula for dry, irritated lungs caused by warm-dry environmental conditions that have damaged both the moisture and Qi of the Lungs. It is commonly used for dry cough with no phlegm, wheezing, dry throat and nose, thirst, and mild fever, especially during dry autumn weather or after a feverish illness has dried out the respiratory system.

TCM Patterns
In TCM, symptoms don't appear randomly — they cluster into recognizable patterns of disharmony that reveal what's out of balance in the body. Qing Zao Jiu Fei Tang is traditionally associated with these specific patterns.
The following describes this formula's classification within Traditional Chinese Medicine theory and is provided for educational purposes only.
Why Qing Zao Jiu Fei Tang addresses this pattern
Warm dryness (温燥) is an external pathogenic factor that directly attacks the Lungs, scorching their delicate moisture and impairing their ability to descend Qi and distribute fluids. This formula clears the dryness-heat with Sang Ye and Shi Gao, restores Lung moisture with Mai Men Dong, E Jiao, and Hu Ma Ren, descends rebellious Lung Qi with Xing Ren and Pi Pa Ye, and supplements the Qi the Lungs need to recover with Ren Shen and Gan Cao. The combination of clearing, moistening, descending, and tonifying comprehensively addresses the Lung Dryness pattern.
A practitioner would look for one or more of these signs
Dry cough with no phlegm or very scanty, sticky phlegm
Qi rebelliously rising, causing wheezing and labored breathing
Dry, parched throat and nose
Thirst with desire for fluids
Mild fever and headache
Fullness and discomfort in the chest and flanks
Why Qing Zao Jiu Fei Tang addresses this pattern
When warm dryness damages the Lungs severely enough, it consumes both Lung Yin (moisture) and Lung Qi. The Yin deficit manifests as dryness, thirst, and a dry tongue with little coating. The Qi deficit shows as fatigue, a large but weak (虚大) pulse, and difficulty breathing. This formula addresses both aspects: Mai Men Dong, E Jiao, and Hu Ma Ren replenish Yin, while Ren Shen and Gan Cao restore Qi. This dual approach is essential because neither Yin nor Qi alone can restore the Lungs to normal function.
A practitioner would look for one or more of these signs
Dry cough that is weak and unproductive
Shortness of breath and fatigue
Persistent thirst, dry mouth
Dry tongue with little or no coating
How It Addresses the Root Cause
This formula addresses the pattern of warm Dryness injuring the Lungs with damage to both Qi and Yin (温燥伤肺，气阴两伤证). In TCM theory, the Lungs are considered a 'delicate organ' (娇脏) that prefers moisture and is easily harmed by Dryness. When warm, dry climatic influences (most typically in autumn) invade the body, they attack the Lungs first, scorching the Lung's protective fluids and disrupting its normal descending and dispersing functions.
As warm Dryness dries out the Lung's fluid lining, the Lungs lose their ability to moisten the airways and send Qi smoothly downward. This produces a dry, hacking cough with little or no phlegm, wheezing, and a feeling of tightness in the chest. Because the Lungs open to the nose and govern the skin, Dryness also causes dry nose, dry throat, and thirst. The Heat component brings fever, headache, and irritability. On a deeper level, the sustained drying and heating depletes both the body's Yin (nourishing fluids) and Qi (functional vitality). The pulse becomes 'vacuous, large, and rapid' (虚大而数), reflecting underlying depletion beneath the surface Heat, while the tongue is dry with little or no coating, confirming fluid exhaustion.
A critical insight from formula creator Yu Chang is that the Lungs do not exist in isolation. According to Five Phase theory, Earth (Spleen/Stomach) is the 'mother' of Metal (Lungs), and Water (Kidneys) is the 'child' of Metal. When Lung Dryness is severe, both the mother and child suffer: the Stomach fails to generate enough fluids to feed the Lungs, and the Kidneys below receive insufficient moisture. The formula therefore must not only clear the Dryness-Heat directly from the Lungs, but also replenish fluids from their deeper sources by nourishing both the Stomach (the mother) and the Kidney Yin (the child), while simultaneously restoring Lung Qi so the organ can resume its governing role.
Formula Properties
Cool
Predominantly sweet and bland with mild bitterness. Sweet herbs (Ren Shen, Gan Cao, Mai Men Dong, E Jiao) tonify Qi and nourish Yin; bland and rich herbs (Hu Ma Ren) moisten without cloying; mild bitterness (Xing Ren, Pi Pa Ye) descends Lung Qi. The formula deliberately avoids strong bitter or acrid flavors to protect the already damaged Lung fluids.
