devadārośca vai cūrṇaṃ ajāmatreṇa bhāvayet /
ekaviṃśativāraṃvaitvakṣiṇī tena cāñjayet /
rātryandhatā paṭalatā naśyennirlomatā tathā //

One should steep the powder of devadāru in goat's urine / twenty-one times, and then apply it to both eyes; / night blindness, membrane disease, and loss of eyelashes are thus destroyed.
