Qing Fei San is a focused 5-herb formula in which each ingredient contributes a targeted action to clear Lung Heat and resolve Phlegm-Heat:
Qing Fei San contains Heat-clearing and Phlegm-transforming herbs, including Ban Lan Gen (Isatis) and Ting Li Zi (Pepperwort Seed), which may affect cardiac function, fluid balance, and drug metabolism. Pets currently on prescription medications should use this formula under veterinary supervision, as herb-drug interaction research in dogs and cats remains limited.
Medication categories warranting extra caution include cardiac medications, diuretics, antibiotics or antiviral drugs used concurrently for respiratory conditions, and pets managing multiple concurrent prescriptions. Your veterinarian can determine appropriateness based on your pet's condition, current medications, and laboratory results.

In Traditional Chinese Veterinary Medicine, Qing Fei San is indicated for Lung Heat and Phlegm-Heat patterns affecting the respiratory tract. It is commonly recommended for dogs, cats, and horses showing signs of cough, respiratory discomfort, nasal discharge, or airway irritation rooted in Lung Heat accumulation, particularly when accompanied by a red tongue with a yellow coat and a rapid, slippery pulse.
Mix the concentrated powder directly into wet or dry food at each meal using the included double-sided scoop. Capsules can be given whole or opened and sprinkled over food. For horses, administer the powder as a top dressing on feed. Dosing is based on species and body weight; your authorizing veterinarian will confirm the correct dose and schedule.
Both Qing Fei San and Red Lung share the same classical name and source text (Qing Fei San from Yuan Heng Liao Ma Ji, 1608), but they are distinct Jing Tang formulas with different herb compositions. Qing Fei San is a focused 5-herb formula emphasizing Lung Heat clearance and Phlegm-Heat resolution. Red Lung is a broader formula that also addresses Blood circulation and Yin nourishment alongside Lung Fire clearance. Your authorizing veterinarian will determine which formula best matches your pet's TCVM pattern based on tongue, pulse, and clinical signs.
Results vary depending on the severity and chronicity of the condition. For acute Lung Heat patterns, many pet owners begin to notice improvements in respiratory comfort and cough frequency within 2 to 4 weeks of consistent use. This formula is recommended for use up to 3 months; your veterinarian will guide reassessment intervals based on your pet's response.
