DETERMINANTS OF VARNA AND ITS MANIFESTATION AS DESCRIBED IN CHARAKA SAMHITA

INTRODUCTION: The constructs of Varna (cutaneous chromatic expression) and Varnotpatti (biological genesis of complexion) in the Charaka Samhita constitute an integrated Ayurvedic framework linking the dermatological phenotype to sys-temic physiological status. Acharya Charaka delineates Varna as an emergent property of balanced Dosha, op-timally functioning Dhatu, and unimpaired Agni, with particular emphasis on the qualitative integrity of Rasa and Rakta Dhatu. The treatise attributes Varnotpatti to the coordinated operation of Srotas, nutrient assimilation, Ojas stability, and Satva–Tamas equilibrium at the psychosomatic level. Furthermore, it recognises Bija-Bhava, intrauterine milieu, diurnal and seasonal influences, and Ahara-Vihara determinants as critical contributors to complexion development and modulation. This technical review elucidates these determinants as described in Charaka Samhita, offering a mechanistic interpretation of Ayurvedic dermatophysiology and its potential ap-plicability to contemporary integrative and cutaneous health paradigms. AIMS AND OBJECTIVES 1. To critically examine the Ayurvedic determinants of Varna and the physiological process of Varnotpatti as described in Charaka Saṁhita. 2. To analyse the roles of Dosha, Dhatus, Agni, Srotas and Ojas in complexion development and modulation. METHODS A comprehensive search was undertaken, and relevant print and online sources were consulted. This study is concluded under the following points- 1. Literary review 2. Analytical study 3. Critical study RESULTS The analysis of Charaka Samhita reveals that Varna and Varnotpatti are governed by a multidimensional inter-play of physiological, nutritional, psychological, and environmental determinants. Among these, the functional integrity of Rasa and Rakta Dhatu, stability of Agni, and unobstructed Srotas emerged as primary contributors to a healthy complexion. CONCLUSION The study concludes that the Charaka Samhita presents a comprehensive and integrative model of complexion physiology, in which Varna serves as a clinical marker of systemic balance. The classical framework describes Varnotpatti as a result of harmonised interactions among Dosha, Dhatu, and Agni, supported by proper nutrient assimilation and robust Ojas.
