Note 2843 — BOOK XXIII. THE REMEDIES DERIVED FROM THE CULTIVATED TREES.
John Bostock translation
Saracenus, upon Dioscorides, B. v. c. 6, thinks that Pliny, in copying from the Greek, has made a mistake here, and that he has taken οὖλον, the “gums,” for οὐλὴ, a “cicatrix;” the corresponding passage in Dioscorides being οὖλα πλαδαρὰ, “flaccidity,” or “humidity of the gums.”
