τοῦτο γὰρ καὶ ἐπὶ τῶν ἀγρίων καὶ τῶν ἡμέρων ὁρῶμεν, ὧν αἱ ῥίζαι πικραὶ καὶ ὀπώδεις τούτων τοὺς καρποὺς γλυκεῖς ὄντας ὡς ἂν ἐξ ἀπέπτου τινὸς πεπεμμένους ὄντας· ταὐτὸν δὲ καὶ ἐν ταῖς τῶν φαρμάκων δυνάμεσιν ὑποληπτέον συμβαίνειν ὥστ᾽ οὐκ ἄλογον εἰς ἔνια μὲν τὰς ῥίζας ἰσχύειν μᾶλλον εἰς ἔνια δὲ τῶν λοιπῶν τι μερῶν. ἐπεὶ καὶ ῥίζαι ῥιζῶν ἐν τοῖς ὁμογενέσι καὶ σπέρματα σπερμάτων καὶ τἆλλα μέρη πολὺ διαφέρουσιν ἰσχύϊ διὰ τὸν ἀέρα ἑκάστης χώρας, ὥσπερ καὶ ὁ σῖτος καὶ οἱ ἄλλοι καρποὶ τῇ βαρύτητι καὶ κουφότητι διὰ τὰς τροφάς.
