A Composite Correlation Index–based Methodology for Evaluating Ayurvedic Anatomical Concept

Abstract

Ayurvedic anatomy (Rachana Sharir) provides an integrative understanding of the human body through structural, functional, and vital concepts such as Asthi, Sandhi, Sira, Dhamani, Srotas, Dhatu, and Marma. Unlike modern anatomy, which is largely based on dissection and imaging techniques, Ayurvedic anatomical descriptions integrate bodily structures with physiological functions and life principles. However, the absence of a standardized quantitative framework has limited the systematic scientific validation of these classical concepts. The present study aims to evaluate the anatomical and functional validity of Ayurvedic Rachana Sharir principles using the composite correlation index (CCI) as a structured validation tool. Selected Ayurvedic anatomical entities and broader physiological principles, including the Tridosha–Sharir relationship, Marma, Srotas, and Dhatu, were analyzed using the CCI model. The correlation was assessed across multiple domains such as structural correspondence, spatial localization, functional relevance, and clinical significance, and expressed as composite scores. The calculated CCI values demonstrated strong to very strong positive correlations between Ayurvedic anatomical entities and their modern anatomical counterparts, with mean scores ranging from 75 to 100. These findings indicate a high degree of structural and functional concordance, highlighting the precision and systematic nature of classical Rachana Sharir descriptions. The study establishes the CCI as a reliable quantitative framework for validating Ayurvedic anatomical principles and bridging classical Ayurvedic knowledge with contemporary biomedical science.
