 +"​F.ornus yields manna (Manna cannelata) - fried sugary exudate that flows after insect damag or after deliberate incisions of the bark during warm, dry weather... Manna is composed mainly of D-mannitol (70-90%), with smaller amounts of D-glucose, D-fructose and oligosaccharides... Manna is a useful laxative, especially when a soft stool is required (in cases of painful haemorrhoides,​ anal fissures or after surgery)."​ \\

 +"​Fraxinus ornus bark is used in the traditional medicine for wound healing and treatment of inflammation, ​
 +arthritis and dysentery. Biological studies on crude extract, many of its constituents and some extractives have revealed significant antimicrobial,​ antioxidative and photodynamic damage prevention, wound healing, anti-
 +inflammatory,​ immunomodulatory and antiviral activities providing a support to the ancient claims. Chemical studies on bark, leaves and flowers of F. ornus have shown the presence of many compounds belonging mainly to the groups of hydroxycoumarins, ​ secoiridoid ​ glucosides, ​ phenylethanoids ​ and  flavonoids. F. ornus is rich in hydroxycoumarins. Esculin, esculetin [6,​7-dihydroxycoumarin],​ fraxin and fraxetin are the main components of the bark." \\
