Dr. Kumari Madhavi* and Dr. Namrata Khobragade
ABSTRACT
In Ayurveda, Shwasa Roga is characterized predominantly with difficulty in Shwasa Prashwasa (breathing) in which due to obstruction in the Pranavaha Strotas the regular process of Nishwasana (inhalation) and Uchhwasana (exhalation) gets disrupted and the patient experiences difficulty in breathing. Shwasa Roga are predominant in Kapha and Vata. Most Nidanas consist of Vata and Kapha Janaka Hetus. Apart from Aharj Nidana, Rajas-Dhuma (dust, smoke, fumes), Megha-Ambu-Shita-Pragvata (seasonal changes) etc which are mentioned in Viharaj Nidana has been accepted as the major cause for Shwasa Vyadhi. These Nidanas result in Vata Prakopa, which obstructs the passage and itself being obstructed moves here and there, and produces Shwasa (dyspnoea) and makes Shwasa Roga. The Pranavaha, Udakavaha and Annavaha Strotas plays a major role in pathogenesis. Manifestation of Pranavayu Vilomatva, Anaha and Parshwashoola are important Poorvaroopa. This article is based on review on Nidana Panchaka of Shwasa Roga from Ayurvedic text such as Charaka Samhita, Sushruta Samhita, Astanga Hrudaya, Astanga Sangraha and Madhava Nidana along with textbooks. Understanding the Nidana Panchaka in detail and comprehending Samprapti would help us design particular preventive actions and handle the specifics of the Nidana Panchaka of Shwasa Roga.
