Clears Lung Heat — used for pneumonia, cough with fever, respiratory tract infections, and common cold with heat signs
Relieves toxicity — used for febrile infections and toxic heat patterns in the upper burner
Secondary Actions
Clears heat from the respiratory tract to reduce fever and relieve cough with yellow phlegm
Classical References
Dumu Materia Medica (Tibetan regional pharmacopoeia) — documents Gao Shan La Gen Cai for clearing heat from the Lungs and treating respiratory disorders
Modern Research
Active Compounds
Flavonoids — identified by phytochemical investigation as primary secondary metabolites; antioxidant and anti-inflammatory
Glucosinolates — characteristic Brassicaceae family compounds; potential antimicrobial and anti-inflammatory activity
Phenolic acids — antioxidant fraction identified in metabolomic profiling
Studied Effects
Lung-protective — network pharmacology and transcriptomics analysis demonstrates mechanistic basis for alleviating LPS-induced acute lung injury; anti-inflammatory targets identified
Antimicrobial and antiviral — consistent with clinical use for pneumonia and respiratory infections; formal mechanistic studies ongoing
Safety & Interactions
Contraindications
Cold-type respiratory conditions — cold nature is contraindicated for Lung cold or wind-cold cough without heat signs
Cautions
Sparsely documented in international literature — English-language clinical safety data is limited; herb is regionally used in Tibetan and high-altitude Chinese medicine
