Sanjeevani is a magical herb which has the power to cure any malady. It was believed that medicines prepared from this herb could revive a dead person. Herb is mentioned in the Ramayana when, Ravana's son Indrajit hurls a powerful weapon at Lakshmana. Lakshmana is badly wounded and is nearly killed by Indrajeet. Hanuman was called upon to fetch this herb from the mount Dunagiri (Mahodaya) in the Himalayas or Valley of Flowers.
