Passage 9.41.7
ἐνταῦθα ἐν τῇ Χαιρωνείᾳ μύρα ἀπὸ ἀνθῶν ἕψουσι κρίνου καὶ ῥόδου καὶ ναρκίσσου καὶ ἴρεως· ταῦτα ἀλγηδόνων ἰάματα ἀνθρώποις γίνεται. τὸ δὲ ἐκ τῶν ῥόδων ποιούμενον, εἰ καὶ ἀγάλματα εἰργασμένα ξύλου χρίοις, ῥύεται καὶ ταῦτα σηπεδόνος. ἡ δὲ ἶρις φύεται μὲν ἐν ἕλεσι, μέγεθος δʼ ἐστὶν ἴση κρίνῳ, χρόαν δὲ οὐ λευκή, καὶ ὀσμὴν ἀποδεῖ κρίνου.
Here in Chaeronea they boil perfumes from the flowers of lily, rose, narcissus, and iris; these serve men as remedies against pains. The perfume made from roses, even if applied to statues carved from wood, protects even these from decay. Iris, which grows in marshy places, is equal in size to the lily, but differs from it in color, for it is not white, and has a weaker scent than the lily.
