SB 8.8.34
	sa vai bhagavatah saksad
	 visnor amsamsa-sambhavah
	dhanvantarir iti khyata
	 ayur-veda-drg ijya-bhak
	Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
	This person was Dhanvantari, a plenary portion of a plenary portion of Lord Visnu. He was very conversant with the science of medicine, and as one of the demigods he was permitted to take a share in sacrifices.
	Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
	Srila Madhvacarya remarks:
	tesam satyac calanartham
	 harir dhanvantarir vibhuh
	samartho ’py asuranam tu
	 sva-hastad amucat sudham
	Dhanvantari, who was carrying the jug containing nectar, was a plenary incarnation of the Supreme Personality of Godhead, but although he was very strong, the asuras were able to take the jug of nectar from his hands.
