Classical Insights into Nasa Rachana And Nasyakarma: An Evidence-Oriented Review

Background: Nasa (nose) is regarded in Ayurveda as the principal seat of Ghranendriya and the gateway to Shiras (head). It plays a crucial role in respiration, olfaction and the administration of Nasyakarma, an important Panchakarma procedure. Objective: To critically review the anatomical concepts of Nasa and the therapeutic principles of Nasyakarma described in classical Ayurvedic literature. Materials and Methods: A comprehensive literary review was conducted using major Ayurvedic Samhitas, classical commentaries, standard textbooks and relevant published literature. Information related to the structure, development, measurements, Marma, physiological significance and therapeutic applications of Nasa and Nasyakarma was systematically compiled and analyzed. Results: Classical texts provide detailed descriptions of Nasa, including its embryological development, anatomical components, Marma associations and clinical relevance. Nasyakarma is described as an effective therapeutic intervention for various disorders of the nose, head and upper body owing to the unique relationship between Nasa and Shiras. Conclusion: The Ayurvedic concepts of Nasa and Nasyakarma demonstrate a comprehensive integration of anatomy and therapeutics, highlighting their enduring relevance in contemporary Ayurvedic practice and research.
