Exploring Vaidyachandrodaya: A Comparative Study with Madhava Nidana

Vaidyachandrodaya is an ancient Ayurvedic Nidana text authored by Shree Trimallabhatta. Diagnosis (Nidana) forms the first and most crucial stage of Chikitsa (treatment), and this work systematically elaborates diagnostic principles and disease evaluation.To highlight the literary structure, diagnostic approach, and distinctive features of Vaidyachandrodaya in comparison with classical Nidana texts. A literary review of Vaidyachandrodaya along with comparative references to Madhava Nidana was undertaken to analyze its structure, arrangement of chapters, and unique contributions. The text is composed in poetic form and contains 81–82 chapters termed Avalokana, each named after a specific disease. It elaborates Ariṣṭa Lakṣaṇas, Doṣa prakopakara causes, and detailed symptomatology of various diseases such as Jwara, Atisara, Grahani, Arsha, Ajeerna, and Krimiroga. It also describes diagnostic procedures including Mutra Pareeksha and Mala Pareeksha. Although the order of diseases largely follows Madhava Nidana, certain additions, omissions, and rearrangements of chapters make it distinctive. The inclusion of specific disease-based Avalokanas and systematic listing of chapters further reflect its structured composition. Vaidyachandrodaya is a significant Nidana Grantha that presents a systematic and poetic exposition of disease diagnosis in Ayurveda, contributing uniquely to the classical diagnostic literature.
