AYURVEDIC PHARMACODYNAMICS AND DRUG DISCOVERY: ROLE OF DRAVYAGUNA SIDDHANTA IN PREDICTING THERAPEUTIC EFFICACY AND SAFETY

Abstract

The increasing demand for safe, effective, and evidence-based therapeutic agents has renewed interest in traditional medical systems as valuable sources for drug discovery. Ayurveda possesses a sophisticated pharmacodynamic framework known as Dravyaguna Siddhanta, which systematically explains the properties, actions, therapeutic applications, and safety profiles of medicinal substances. The principles of Dravya, Rasa, Guna, Virya, Vipaka, and Prabhava collectively provide a multidimensional approach for predicting therapeutic efficacy and potential adverse effects. Unlike conventional drug discovery strategies that often rely on target-based screening, Ayurvedic pharmacodynamics emphasizes holistic assessment of medicinal substances based on their intrinsic attributes and biological interactions.The present review aims to explore the role of Dravyaguna Siddhanta in predicting therapeutic efficacy and safety from the perspective of contemporary drug discovery. Classical Ayurvedic literature and modern scientific evidence were critically analyzed to identify correlations between traditional pharmacodynamic principles and experimentally validated pharmacological activities. Evidence suggests that the systematic evaluation of medicinal plants through Dravyaguna Siddhanta may facilitate the identification of bioactive compounds, prediction of therapeutic responses, assessment of safety profiles, and prioritization of candidate drugs for further investigation. Furthermore, concepts such as Virya, Vipaka, and Prabhava may provide valuable insights into pharmacodynamics, metabolism, and unique biological effects that are not readily captured by reductionist approaches. Integrating Ayurvedic pharmacodynamics with modern pharmacology and reverse pharmacology may offer a promising strategy for accelerating drug discovery, improving safety assessment, and advancing evidence-based herbal medicine research.
