Praphulla Chandra Ray's 'A History of Hindu Chemistry' is a pivotal exploration into the alchemistic traditions of India, tracing back from the ancient era to the 16th century. Acknowledged as a pioneer in Indian chemistry, Ray embarked on this scholarly journey to uncover and document the rich legacy of alchemical knowledge and practices within Hindu culture, which he perceived as undervalued and obscure due to their intricate and specialized nature. The initial volume focuses on the alchemical contributions of ancient Ayurvedic luminaries such as Charaka and Susruta, highlighting their significant roles in the early development of chemical science. Ray's work is pivotal in bridging the ancient alchemical traditions with the realm of contemporary chemistry, aiming to amplify India's contribution to the scientific world through a meticulous blend of historical insight and scientific analysis
