ROLE OF PRATIMARSHA NASYA IN PREVENTING MICROBIAL INVASION THROUGH NASAL MUCOSA: A REVIEW

The nasal cavity serves as the primary gateway to the respiratory system and is constantly exposed to environmental pollutants and microorganisms. Respiratory infections are a significant global health concern, and the nasal mucosa acts as the body's first line of defense against airborne pathogens and environmental pollutants. When the mucosal barrier is compromised due to dryness, irritation, or inflammation, it becomes susceptible to microbial invasion. Modern preventive measures often focus on external protection, such as masks and air filtration systems, overlooking the importance of strengthening the nasal mucosa. With its holistic and preventive approach, Ayurveda emphasizes the practice of Pratimarsha Nasya, a daily administration of medicated oils into the nostrils, as an effective way to fortify this vital barrier. This article explores the scientific and therapeutic basis of Pratimarsha Nasya in preventing microbial entry through the nasal mucosa. When applied daily, it hydrates the nasal mucosa, creates a protective layer, and enhances local immunity, making it resistant to microbial attachment and invasion. In an era where respiratory infections increasingly burden public health, Pratimarsha Nasya emerges as a sustainable and integrative solution that complements conventional preventive measures. By combining ancient wisdom with modern scientific insights, this practice holds immense potential for global implementation as a natural, cost-effective strategy to safeguard respiratory health and reduce the incidence of airborne infections.
