Tobit 6:6-8

Revised Standard Version Catholic Edition

⁶ Then the young man said to the angel, “Brother Azari′as, of what use is the liver and heart and gall of the fish?” ⁷ He replied, “As for the heart and the liver, if a demon or evil spirit gives trouble to any one, you make a smoke from these before the man or woman, and that person will never be troubled again. ⁸ And as for the gall, anoint with it a man who has white films in his eyes, and he will be cured.”
