According to the Hindu mythology during the churning of the ocean, Vishnu, the physician of gods is believed to be produced with a cup of nectar in his ahnd that represents the true healer in all beings.

Dhanvantari (also Dhanwantari, Dhanvanthari) (धन्वंतरी) is an avatar of Vishnu from the Hindu tradition. He appears in the Vedas and Puranas as the physician of the gods (devas), and the controller (god) of Ayurvedic medicine. It is common practice within Hinduism for worshippers to pray to Dhanvantari asking him for improved or good health for themselves and/or others.
