KĀSA ROGA – Ayurvedic Management of Cough
🔍 1. Definition of Kāsa
“Prāṇavāyu prakupyeta śoṣayet kaṇṭhamārutam | Utkṣipya śuṣkakāsārthaṁ kāsaṁ tamāhurāmayam ||”
— Charaka Saṃhitā Chikitsā Sthāna 18/4
Kāsa is a condition where aggravated Prāṇa Vāta affects the Uras (chest), Kaṇṭha (throat), and Śvāsa mārga (respiratory tract), leading to coughing – dry or productive.
