Background: Kaphaja Kāsa associated with Śvāsa represents a Kapha-dominant respiratory disorder characterized by productive cough, airway obstruction, and dyspnea. Acute exacerbations (Atyayika Avastha) require prompt intervention to relieve Srotorodha and restore respiratory function.  Case Presentation: A 42-year-old male presented with severe productive cough, chest congestion, dyspnea at rest, throat irritation, and disturbed sleep for seven days. Peripheral oxygen saturation (SpO₂) was 87% on room air. Based on Ayurvedic evaluation, the condition was diagnosed as Kaphaja (Drava) Kāsa with Śvāsa in Atyayika Avastha. Intervention: The patient was administered Sitopaladi Churna (3 g), Shrungarabhra Rasa (250 mg), and Shwaskuthar Rasa (250 mg) twice daily with honey. Kanakasava (5 ml) and Dashamularishta (5 ml) were given twice daily after meals with equal water. External application of Saindhavadi Taila followed by mild fomentation was performed. Outcome: Within 4 hours, dyspnea reduced significantly and SpO₂ improved from 87% to 95%. By day 5, sputum and chest congestion reduced markedly. By day 10, approximately 90% overall symptomatic relief was observed. No adverse events were reported. Conclusion: Classical Ayurvedic management demonstrated rapid clinical improvement in acute Kaphaja Kāsa with Śvāsa. Further controlled clinical studies are warranted.
