PROTOCOL DESIGN FOR AN OBSERVATIONAL STUDY ON THE VARIATION IN CAUSATIVE FACTORS OF VYANGA (MELASMA) W.S.R. TO DAIHIK PRAKRITI

Background-Vyanga (Melasma) is a Kshudra Roga (minor skin disorder) described in Ayurveda, characterized by Shyava Varna Mandala (bluish-black patches) on the face due to vitiation of Vata and Pitta Dosha. In modern dermatology, Vyanga is correlated with melasma, a hyperpigmentation disorder linked to genetic, hormonal, and environmental factors. The concept of Daihik Prakriti (body constitution) in Ayurveda determines individual susceptibility to diseases and influences the skin's response to internal and external stimuli. This study aims to assess the variation in causative factors of Vyanga with special reference to Daihik Prakriti. Objectives-To analyze the Samprapti (pathogenesis) of Vyanga in relation to Daihik Prakriti.
