Rasayana Therapy: Boon to Check the Diseases of Modern Civilization

Abstract

Oxidative stress is a major contributory factor in the pathogenesis of numerous present-day diseases. Oxidative stress can induce damage at the DNA level, leading to mutagenesis and disease progression. Cell injury may also occur due to factors such as impaired bioavailability, metabolic dysfunction, and psychological stress. Rasayana, one of the eight branches of Ayurveda, offers a comprehensive preventive and rejuvenative approach to counteract these mechanisms. Rasayana therapy nourishes the Dhatus, which can be correlated with cellular and tissue-level nutrition, and acts through the Atma–Mana–Sharira complex at the levels of Rasa, Agni, and Srotas. Classical texts describe Rasayana as promoting longevity, strength, intellect, complexion, and resistance to disease, while delaying senility. Materials and Methods: This review is based on classical Ayurvedic texts including Charaka Samhita, Sushruta Samhita, and Ashtanga Hridaya, along with modern medical literature such as Davidson’s Principles and Practice of Medicine, standard textbooks, and publications from PubMed and CCRAS. Discussion: Rasayana therapy encompasses Ahara, Vihara (Achara Rasayana), and Aushadha, selected according to individual needs. Its antioxidant-rich drugs, such as Ashwagandha and Amalaki, enhance digestion, metabolism, and tissue nourishment, thereby counteracting oxidative damage. Conclusion: Preventive healthcare is the need of the hour. Rasayana therapy, with its antioxidant, rejuvenative, and holistic actions, represents a promising strategy for health promotion, disease prevention, and healthy aging.
