The systematic name of the tree whence manna flows. This substance is also called Manna Calabrina, Ros Calabrinus, Aeromeli, Drosomeli, Drysomeli, Mel aerium. Succus orni concre'tus. In Sicily, not only the Fraxinus Ornus, but also the F. rotundifolia and F. excelsior are regularly cultivated for the purpose of procuring manna, which is their condensed juice. In the Ph. U. S. it is assigned to Ornus Europoea. Manna is inodorous, sweetish, with a very slight degree of bitterness; in friable flakes, of a whitish or pale yellow colour; opake, and soluble in water and alcohol. It is laxative, and is used as a purgative for children, who take it readily on account of its sweetness. More generally it is employed as an adjunct to other purgatives. Its immediate principle is called Mannite or Mannin. This has been recommended by Magendie as a substitute for manna.
