Physiological Understanding of Dhatu Poshan Nyaya in Ayurveda

Ayurveda explains the nourishment of body tissues (Dhatus) through the fundamental concept of Dhatu Poshan Nyaya. This concept describes how nutrients derived from digested food are transformed and distributed sequentially to sustain the structural and functional integrity of the body. Classical Ayurvedic texts propose different models of tissue nourishment, namely Ksheera-Dadhi Nyaya, Kedari-Kulya Nyaya, and Khale-Kapota Nyaya, each explaining specific aspects of nutrient transport and metabolism. From a physiological perspective, these models can be correlated with modern concepts such as digestion, absorption, circulation, cellular metabolism, and tissue-specific utilization of nutrients. The present study aims to analyze Dhatu Poshan Nyaya and interpret its relevance in the light of contemporary physiology. Understanding these principles provides a strong foundation for explaining health, disease progression, and tissue metabolism in Ayurveda.
