karavīraṃ bhṛṅgapatraṃ lavaṇaṃ kuṣṭhakarkaṭe /
caturguṇena mūtreṇa pacettailaṃ harecca tat /
pāmāṃ vicarcikāṃ kuṣṭhamabhyaṅgāddhi vraṇāni vai //

One should cook oil with karavīra, bhṛṅgarāja leaves, salt, kuṣṭha, and karkaṭaśṛṅgī, / with four times as much urine; it removes / scabies, eczema, leprosy, and ulcers through anointing.
