Chyavana is mentioned in the Rigveda as Chyavāna (च्यवान). He is described as an aged and feeble person whose youth and strength was restored by the twin Ashvini Kumar brothers, who were the Rajya Vaids or 'State Doctors'. According to a hymn of this text (X.61.1-3), Chyavāna seems to be opposed to Turvayana, an Indra worshipper Paktha king as he was closer to the Ashvins.
