Dhanvantari (Sanskrit: धन्वन्तरि, romanized: Dhanvantari) is the physician of the devas (Gods) in Hinduism. He is regarded to be an avatar of Vishnu and is mentioned in the Puranas as the god of Ayurveda.
During his incarnation on earth, he reigned as the King of Kashi, today locally referred to as Varanasi.
According to the ancient Sanskrit work Vishnudharamottara, Dhanvantari is a handsome individual and is to usually be depicted with four hands, with one or two of them carrying a bowl of amrita, the elixir of immortality. Dhanvantari is depicted in a stark resemblance to Vishnu, with four hands, holding the shankhu, chakra, jalauka (leech), and a pot containing amrita. He is often shown with a leech in his hand rather than the scriptures, indicating the historical practice of bloodletting.
Devotees pray to Dhanvantari to seek his blessings for sound health for themselves and others on Dhanteras, two days before Deepavali. It is also celebrated as National Ayurveda Day in India, which was first observed in 2016
