Cough

Traditional Chinese Medicine Definition
Cough, known as "Ke Ni" (rebellious cough) in traditional Chinese medicine, refers to a lung-system disease characterized by the failure of lung Qi to diffuse and descend, with Qi rebelling upward and striking the airway, producing coughing sounds, sometimes accompanied by sputum expectoration. The TCM classic "Internal Medicine of Traditional Chinese Medicine" records: "Cough is caused by the upward rebellion of lung Qi and the unsmooth flow of sputum."
The clinical syndrome differentiation of cough primarily revolves around the core pathogenesis of lung dysfunction. Common triggers include invasion of exogenous wind-cold and wind-heat pathogens, as well as internal accumulation of phlegm-dampness. During syndrome differentiation, attention should be paid to the following key points:
1. Cold, heat, deficiency, and excess: Wind-cold attacking the lung syndrome is characterized by a heavy coughing sound, white clear sputum, nasal congestion and runny nose, aversion to cold and fever; wind-heat invading the lung syndrome is characterized by frequent and severe coughing, yellow sticky sputum, sore throat, and thirst; phlegm-dampness accumulating in the lung syndrome is characterized by cough with copious sputum, heavy coughing sound, chest oppression and epigastric fullness, poor appetite, and fatigue.
2. Key points of syndrome differentiation: Observe the nature of the cough, the color and texture of sputum, and accompanying symptoms such as aversion to cold, fever, thirst, and chest oppression.
Overall direction of regulation: In TCM clinical practice, the treatment of cough follows the basic principles of diffusing the lung to stop cough, and resolving phlegm to benefit the lung. Based on different syndrome types, methods such as dispersing wind and cold, dispersing wind and clearing heat, or drying dampness and resolving phlegm may be adopted. Traditional Chinese medicine holds that through syndrome differentiation and treatment, the goals of relieving symptoms and restoring lung function can be achieved.
Common Syndrome Types and Key Points of Differentiation
Wind-Cold attacking the Lung syndrome
Main Manifestations: Heavy cough, white and thin phlegm, nasal congestion with runny nose, aversion to cold and fever
Management Approach: Disperse Wind and Relieve Cold, Ventilate the Lungs and Relieve Cough
Wind-Heat attacking the Lung syndrome
Main Manifestations: Severe coughing, thick yellow phlegm, sore throat, and thirst
Management Approach: Disperse Wind and Cool Heat, Ventilate the Lungs and Relieve Cough
Phlegm-Dampness Retention in the Lung syndrome
Main Manifestations: Excessive phlegm in cough, heavy and thick cough sound, chest oppression, epigastric discomfort, decreased appetite, fatigue
Management Approach: Dry Dampness and Resolve Phlegm, Regulate the Lungs and Relieve Cough
The above syndrome information is based on traditional Chinese medicine textbooks and clinical standards. Specific differentiation should be completed by a practicing traditional Chinese medicine physician in person.
Physician's Clinical Insights
Patients with cough often have failure of lung Qi to diffuse. During treatment, attention should be paid to the relationships among the lung, spleen, and kidney, and to regulating the whole body.
