Fraxinus ornus
Until the end of the 19th century manna was brought to northern Europe from Calabria (manna calabrina) and from Sicilia. She was collected as a secrete from species of "Fraxinus", mainly of "Fraxinus ornus" and of "Fraxinus excelsior". Following the rules of Humorisme, physicians in northern Europe prescribed this manna as a mild laxative.
