ROLE OF YOGA AND KAYACHIKITSA IN INTEGRATIVE MEDICINE: A SCIENTIFIC REVIEW
Introduction: Integrative medicine is an emerging healthcare model that emphasizes blending conventional biomedical practices with complementary and traditional systems for holistic well-being. Ayurveda, particularly its branch Kayachikitsa (internal medicine), and Yoga, rooted in ancient Indian philosophy, contribute to this paradigm by addressing physical, psychological, and spiritual dimensions of health. Methods: Literature was collected from PubMed, Scopus, Web of Science, AYUSH Research Portal, and classical Ayurvedic texts including Caraka Samhita, Sushruta Samhita, and Ashtanga Hridaya. Keywords such as "Kayachikitsa," "Yoga therapy," "integrative medicine," and "chronic diseases" were used. Articles published between 2000–2025, including clinical trials, conceptual reviews, and systematic analyses, were included. Results: Findings reveal that Kayachikitsa emphasizes preventive, promotive, and therapeutic strategies through dietary regulation, Panchakarma, Rasayana therapy, and lifestyle modification, which resonate with modern preventive medicine. Yoga, through Asanas, Pranayama, and meditation, complements Kayachikitsa by regulating stress responses, enhancing neuroendocrine function, and improving cardiometabolic health. Integrative evidence shows significant benefits in non-communicable diseases (NCDs), oncology, mental health, and palliative care. Clinical trials confirm improvements in glycemic control, blood pressure regulation, immune function, anxiety, depression, and quality of life when Ayurveda and Yoga are combined. Discussion: The synergy of Yoga and Kayachikitsa demonstrates strong potential within integrative medicine. Their convergence offers individualized, cost-effective, and patient-centered healthcare. However, gaps remain regarding standardized protocols, mechanistic studies, and large-scale trials. Conclusion: Yoga and Kayachikitsa together enhance resilience, promote holistic well-being, and complement biomedical care. They represent a culturally rooted and scientifically relevant model for integrative medicine in the 21st century.
