Tridosha Siddhanta Across Brihatrayi: A Comparative Literary Analysis

Tridosha Siddhanta is the fundamental theoretical framework of Ayurveda that explains physiological regulation, disease causation, and therapeutic approaches. The Brihatrayi — Charaka Samhita, Sushruta Samhita, and Ashtanga Hridaya — present Tridosha with both shared principles and unique interpretative nuances. The present literary research aims to comparatively analyse the conceptualisation of Vata, Pitta, and Kapha across these classical texts, highlighting similarities, differences, and clinical implications. Classical references were critically reviewed to understand the Dosha origin, qualities, functions, sites, pathological changes, and management principles. The analysis reveals that while Charaka emphasizes physiological and pathological dynamics, Sushruta integrates structural and surgical relevance, and Ashtanga Hridaya presents a concise and clinically applicable synthesis. Understanding these variations enhances the integrative application of Tridosha Siddhanta in contemporary Ayurvedic research and practice.
