Hansodhak: An Ayurvedic Perspective of Water Purification in Sharad Ritu with Modern Correlation

Abstract

Ayurvedic texts emphasize the necessity of pure water for health and disease prevention. Contaminated water (Dushta Jala) has been identified as a major cause of illnesses, especially in the post-monsoon period. The concept of Hansodhak Jala- naturally purified water- describes water acquiring cleansing and therapeutic properties when exposed to Surya (sunlight), Chandra (moonlight), and Agastya Nakshatra (Canopus star). This practice holds particular relevance in Sharad Ritu, a season linked to aggravated Pitta dosha and frequent waterborne diseases. The present study examines classical references to Hansodhak Jala and assesses their symbolic and practical significance. The traditional view is correlated with modern scientific methods of purification, including solar disinfection (SODIS), photodynamic treatment, and seasonal epidemiology. Findings suggest that Hansodhak Jala represents a natural, eco-friendly, and community-based strategy for ensuring water safety. The study concludes that Hansodhak Jala bridges ancient Ayurvedic wisdom with contemporary public health practices, underscoring the enduring relevance of traditional approaches in securing safe drinking water.
