kvāthe muṣkakabhasmano 'nalaśikhādagdhaṃ kṣipec chaṅkhakaṃ
tat tenaiva punar jalena vipacet kṣāraṃ sa taile vidhiḥ /
yuñjyāt tad vraṇaduṣṭiṣu vraṇarujāsv arśassu nāḍīṣu ca
tvagdoṣeṣu bhagaṃdareṣu vividhe kaṇṭhāmaye ca sthire //

One should throw a small conch shell burnt by the fire's flame into a decoction of muṣkaka ash;
one should boil it again with that same water: that alkali is the rule for medicated oil.
One should apply it to foul wounds, wound pains, haemorrhoids, sinus ulcers,
skin diseases, fistula-in-ano, and in various stubborn throat afflictions.
