Fundamental Principles (Siddhanta) of Samhita: A Critical Analytical Study of Brihatrayi

Ayurveda is fundamentally based on classical treatises known as Samhitas. The core philosophical and clinical doctrines (Siddhanta) embedded within these Samhitas form the backbone of Ayurvedic science. The present study critically analyzes the principal Siddhantas described in Brihatrayi—namely Charaka Samhita, Sushruta Samhita, and Ashtanga Hridaya—with special emphasis on Tridosha Siddhanta, Panchamahabhuta Siddhanta, Dhatu-Mala Siddhanta, Agni Siddhanta, and Srotas Siddhanta. The study evaluates their theoretical framework, clinical relevance, and applicability in contemporary healthcare.
