Sanjivani (Hinduism)

[2] The herb is mentioned in the Ramayana when Ravana's son, Indrajit, hurls a powerful weapon at Lakshmana.

In the Kamba Ramayanam, Sushen Vaidh 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.

[3] Unable to identify the herb, and due to time being of the essence, Hanuman lifts the entire mountain and carries it to the dead Lakshmana, who is healed and revived after its application.

A search of ancient texts at CSIR laboratories did not reveal any plant that can be definitively confirmed as sanjeevani.

The Ramayana mentions a mountain believed to refer to the Dronagiri range, where the magical herb is supposed to grow.
