The knowledge of Ayurveda was handed from Brahma to Daksha Prajapati, onto the Ashwin twins (the divine doctors), then passed to Indra. Sage Bharadvaja volunteered to go to heaven to receive this wisdom from Indra, and so become the first human to receive the knowledge of Ayurveda. He passed it to Atreya, then onto Punarnavasu and finally Agnivesha.
