Understanding Dhatu Poshan Nyaya through the Lens of Modern Science: A Narrative Review

Abstract

Background: Dhatu Poshan Nyaya is a foundational Ayurvedic framework describing the processes of tissue nourishment through digestion, metabolism, and nutrient distribution. The classical theory describes four logical principles (Nyaya) that elucidate the processes of sequential tissue transformation, channel-mediated transport, selective assimilation by specific tissues, and concurrent nourishment throughout the body.

Objective: This narrative review synthesizes contemporary scholarship alongside classical Ayurvedic teachings to provide an integrated understanding of Dhatu Poshan Nyaya mechanisms, developmental adaptations, and correlations with modern biomedical concepts.

Methods: A comprehensive literature search was conducted across multiple databases using targeted keywords related to Dhatu Poshan Nyaya. Articles were screened using predefined inclusion and exclusion criteria. Four key peer-reviewed articles “Conceptual Study on Dhatu Poshan Nyaya and a Process of Metabolism,” “Explication on Tissue Nutrition in Prenatal and Postnatal Life,” “A Comprehensive Guide to Dhatu poshana Nyayas,” and “Analytical Review on Basic Tenets of Dhatu Poshan Nyaya as per Contemporary Science” meeting criteria for relevance, scholarly rigor, and thematic focus, formed the basis for narrative synthesis.

Results: The synthesis highlights a multi-layered biochemical and physiological framework of tissue nourishment, developmental transitions from prenatal to postnatal nutrition, and modern correlates in cellular transport mechanisms. Clinical and therapeutic implications for targeted nutrition and drug delivery are discussed.

Conclusion: Dhatu Poshan Nyaya offers a sophisticated, conventionally grounded yet scientifically congruent model of tissue nutrition. Its integration with contemporary biomedical science holds promise for advancing Ayurvedic therapeutics and interdisciplinary research.
