A Comprehensive Review of Rasayana In Ayurveda: Enhancing Longevity and Wellness

Introduction: Rasayana is a vital concept in Ayurveda that aims to promote longevity, enhance vitality, and delay aging. Rooted in classical Ayurvedic texts like the Charaka Samhita, Sushruta Samhita, and Ashtanga Hridaya, Rasayana therapy involves a holistic approach that combines herbal treatments with lifestyle and mental discipline to maintain health and prevent disease. Methods: This review explores the theoretical foundations of Rasayana therapy, drawing on classical Ayurvedic texts and contemporary biomedical findings. It examines Rasayana's role in balancing the body's Dhatus, enhancing immunity, and its antioxidant and adaptogenic properties. Results: Rasayana therapy, which includes herbs like Ashwagandha, Brahmi, Amlaki, and Shankhpushpi, is shown to possess rejuvenating, neuroprotective, and immune-boosting effects. Its benefits are aligned with modern concepts of preventive healthcare, highlighting its adaptiveness to individual constitution (Prakriti), age (Vaya), season (Ritu), and region (Desha). Discussion: Rasayana’s multi-targeted approach makes it relevant in addressing contemporary health challenges such as premature aging, lifestyle disorders, and reduced immunity. Its application ranges from inpatient (Kutipraveshika) to outpatient (Vatatapika) methods, reflecting Ayurveda's flexibility. However, clinical validation and evidence-based research are required for mainstream integration into modern healthcare systems. Conclusion: Rasayana offers a comprehensive, time-tested approach to promoting longevity and health, combining herbal treatments with lifestyle interventions. Its potential as a preventive and therapeutic tool in modern healthcare warrants further research.
