ABSTRACT

Ayurveda has evolved through the collective wisdom of numerous Rishis, Rajarshis, physicians, scholars, and teachers who preserved and developed knowledge of health, disease, longevity, diet, therapeutics, and preventive medicine. Among the distinguished personalities associated with the ancient Ayurvedic tradition is Rajarshi Nagnajita, mentioned in classical Ayurvedic literature and specifically identified as Vayorvida Nagnajita in the Charaka Samhita. His inclusion among the eminent sages associated with the ancient deliberation on Ayurveda establishes his place in the broader intellectual tradition of Ayurveda. This literary study introduces Rajarshi Nagnajita, examines his lineage and geographical association, and critically evaluates his contribution to Ayurveda. Classical sources indicate that Nagnajita was associated with the Gandhara region and belonged to a royal lineage. The Mahabharata identifies Nagnajita as the king of Gandhara and states that his son was Subala, the father of Shakuni and Gandhari. The Bhela Samhita further provides an important account of an encounter between King Nagnajita of Gandhara and Acharya Punarvasu Atreya in the context of food poisoning. Particularly significant is the Charaka Samhita, where Nagnajita's opinions are cited regarding the pathogenesis of disease, the classification and properties of Rasa, the physiological functions of Vata, and the consequences of aggravated Vata. The Kashyapa Samhita also records Nagnajita's views concerning disease classification and describes a discourse concerning paediatric ophthalmic treatment. Further evidence from Ashtanga Sangraha associates Nagnajita with the description of the sequential manifestations of poisoning, including cardiovascular symptoms and death, while Brihat Samhita and Matsya Purana associate him with Pratima-lakshana and Vastu-shastra, respectively. Thus, Nagnajita appears to have been a multidisciplinary scholar-king whose interests extended beyond medicine. His Ayurvedic contribution is particularly noteworthy in Vata-vijnana, Rasa-vijnana, disease classification, toxicology, and preventive understanding of poisoned food. This review suggests that Nagnajita deserves greater recognition as an important contributor to the ancient Ayurvedic intellectual tradition. Rajarshi Nagnajita attended the conclave of rishis held beneath the mountains of the Himalayas some 7000 years ago. This not only shows his interest in medical science but also portrays him as a caring person for mankind's suffering. Hence, exploring the life of Sage Nagnajita is essential to understand his contribution to Ayurveda. Keywords: Nagnajita, Rajarshi, Charaka Samhita, Vayorvida, Vata, Rasa, Agada Tantra, Gandhara.
