Agnivesha (Sanskrit: अग्निवेश, romanized: Agniveśa) is a legendary rishi (sage) in Hinduism, reputedly one of the earliest authors on Ayurveda (Indian alternative medicine).[1][2] He is described to have codified the knowledge of his preceptor, Atreya, and arranged it in the form of a treatise, named the Charaka Samhita.[3]
