May HE shower good health on all of us....
Sri Dhanvantari is the primordial God (Avatar) of health care. As such, persons have taken the name "Dhanvantari" in connection with their attempts at medical interventions. One such Dhanvantari was an early Indian medical practitioner and one of the world’s first surgeons. Based on Vedic traditions, he is regarded as the source of Ayurveda. He perfected many herbal based cures and natural remedies and was credited with the discovery of the antiseptic properties of turmeric and the preservative properties of salt which he incorporated in his cures.
Being a very skilled surgeon according to the standards of his time, he is widely believed to be the pioneer of modern medical practices like plastic surgery.Albeit his methods were a lot cruder and more painful and were used only in emergencies, such as on the injuries of war victims.
Dhanvantari is depicted as Vishnu with four hands, holding medical herbs in one hand and a pot containing rejuvenating nectar called amrita in another. The Puranas state that Dhanavantari emerged from the 'Ocean of Milk' and appeared with the pot of nectar during the story of the Samudra or Sagar manthan whilst the ocean was being churned by the devas and asuras, using the Mandara mountain and the serpent Vasuki. The pot of Amrita was snatched by the Asuras or Demons, and after this event another avatar, Mohini, appears and takes the nectar back from the Asuras.
