A CRITICAL STUDY OF ANATOMICAL CHANGES OF AGING AND EFFECT OF ASHWAGANDHA AS RASAYANA IN LONGEVITY – AN AYURVEDIC REVIEW

Abstract

Background: Aging is a natural and progressive biological process characterized by structural and functional decline in various tissues and organ systems. In modern science, it is associated with cellular senescence, oxidative stress, reduced regenerative capacity, and degenerative anatomical alterations. In Ayurveda, aging is described as Jara, a Swabhavika Vyadhi, primarily influenced by Vata Dosha predominance and gradual depletion of Dhatu. Classical texts emphasize preservation of tissue integrity and vitality through Rasayana therapy. Aim: To critically analyze anatomical changes occurring during aging from both modern and Ayurvedic perspectives and to evaluate the role of Ashwagandha as a Rasayana in promoting longevity. Objectives: To review anatomical and structural changes associated with aging. To analyze the concept of Jara and Dhatu Kshaya in Ayurveda. To evaluate the Rasayana properties of Ashwagandha. To correlate classical descriptions with modern scientific findings on anti-aging effects. Materials and Methods: This is a narrative review based on classical Ayurvedic texts including Charaka Samhita, Sushruta Samhita, and Ashtanga Hridaya, along with modern anatomical, physiological, and pharmacological literature. Relevant research articles on the anti-aging and adaptogenic effects of Ashwagandha were analyzed and interpreted. Results: Aging leads to progressive reduction in tissue elasticity, bone density, muscle mass, neuronal integrity, and immune responsiveness. In Ayurveda, these changes correspond to Vata Vriddhi and Dhatu Kshaya, particularly of Rasa, Mamsa, Asthi, and Majja Dhatu. Ashwagandha, described as Balya, Rasayana, and Vatahara, supports tissue nourishment, enhances strength, improves neuroendocrine balance, and exhibits antioxidant and immunomodulatory properties. Contemporary studies demonstrate its role in reducing oxidative stress, improving muscle mass, supporting bone health, and enhancing cognitive function. Conclusion: Aging reflects both anatomical degeneration and functional decline, which aligns with the concept of Jara in Ayurveda. Ashwagandha, as a potent Rasayana, offers a holistic approach to slow degenerative changes, maintain structural integrity, and promote healthy longevity. Integrating classical wisdom with modern evidence supports its potential role in age-related anatomical preservation.
