Tobit 6:7-9

New Catholic Bible

⁷ Then the youth posed this question to the angel: “Brother Azariah, what medicinal value can there be in the heart, liver, and gall of the fish?” ^8 [a]He replied, “As far as the heart and liver are concerned, when you burn them and the smoke rises in the presence of someone, man or woman, who is afflicted by a demon or an evil spirit, that affliction will disappear for good and will never plague that person again. ⁹ As regards the gall, if you anoint the eyes of someone where white patches have appeared on them and then blow on those patches, the eyes will be healed.”
