Vaidyakalanidhi Shri C. N. Narayanan: A revisionist among Ayurveda physicians of Kerala

In Kerala, the traditional knowledge of Ayurveda was meticulously preserved and disseminated by families of Ashtavaidya tradition and other Vaidya (physicians). The branch of Kaumarabhritya (pediatrics) owes much to the detailed treatises such as “Arogyakalpadrumam” by Kaikulangara Rama Varier and “Vaidyatarakam” by Vaidyakalanidhi C. N. Narayanan (CNN). This paper gives an insight into the life and legacy of CNN, a towering figure who enriched the Ayurvedic community through his academic brilliance, leadership, and editorial prowess. CNN, hailing from a traditional Vaidya family in the central region of contemporary Kerala in India, holds a distinguished position as a Balachikitsaka (pediatrician). His significant contributions to the field of Kaumarabhritya are encapsulated in his seminal work, Vaidyatarakam. This magnum opus delves into unique formulations designed to combat prevalent diseases of his era, such as Karappan (a skin disorder), Romantika Jwara (measles), Nilankari Chuma (whooping cough), and Pilla Vata (polio), among others. He played a crucial role in shaping discussions on professional, academic, and social aspects of Ayurveda. Contrary to the custom of preserving traditional and professional knowledge as a family secret, he devoted himself to spreading his extensive clinical and practical experience. CNN’s tireless efforts have not only enriched the field of Ayurveda but have also contributed to its wider dissemination and understanding.
