The herb is mentioned in the Ramayana when Ravana's son, Indrajita, hurls a powerful weapon at Lakshmana. Lakshmana is badly wounded, and is nearly killed by this attack. In the Kamba Ramayanam, Jambavan instructs Hanuman to fetch the sanjeevani herb by flying to the northern side of Mount Meru, where he would find the Nīla-mahāgiri, the great blue mountain, beyond which he would find the Ṛṣabhādri, the ox-shaped mountain, with two peaks. This mountain is described to bear four medicinal herbs, including sanjeevani.[3] Unable to identify the herb, and due to time being of the essence, Hanuman lifts the entire mountain and carries it to the unconscious Lakshmana, who is healed after its application.[4] The mountain that bears the sanjeevani is also called the Oshadhiparvata.[5]
