rudra lāṅgalikāmūlaṃ cekṣudarbhastathaiva ca /
tena vraṇamukhaṃ liptaṃ śalyaṃ niḥ sa rati vraṇāt /
cirakālapraviṣṭo 'pi tena mārgeṇa śaṅkara //

The root of lāṅgalikā, O Rudra, and ikṣudarbha: / when the orifice of the wound is smeared with it, the foreign body comes out from the wound, / even if entered long ago, by that path, O Śaṅkara.
