Labdanum, also called ladanum, laudanum, ladan or ladanon, is a sticky brown resin obtained from the shrubs Cistus ladanifer (western Mediterranean) and Cistus creticus (eastern Mediterranean), species of rockrose. It has a long history of use in herbal medicine and as a perfume ingredient.
In ancient times, labdanum was collected by combing the beards and thighs of goats and sheep that had grazed on the cistus shrubs. Wooden instruments used were referred to in 19th-century Crete as ergastiri; a lambadistrion ("labdanum-gatherer") was a kind of rake to which a double row of leathern thongs were fixed instead of teeth. These were used to sweep the shrubs and collect the resin which was later extracted. It was collected by the shepherds and sold to coastal traders. The resin was used as an ingredient for incense, and medicinally to treat colds, coughs, menstrual problems and rheumatism.
Ladanum was produced on the banks of the Mediterranean in antiquity. The Book of Genesis contains two mentions of ladanum being carried to Egypt from Palestine. The word loth ("resin") in these two passages is usually interpreted as referring to ladanum on the basis of Semitic cognates.
Percy Newberry, a specialist of ancient Egypt, speculated that the false beard worn by Osiris and pharaohs may have originally represented a "ladanum-laden goat's beard". He also argued that the scepter of Osiris, which is usually interpreted as either a flail or a flabellum, was more likely an instrument for collecting ladanum similar to that used in nineteenth-century Crete.
Some scholars, such as Bochartus, H.J. Abrahams, and Rabbi Saʻadiah ben Yosef Gaon (Saadya), 882-942, state that the mysterious onycha, an ingredient in the holy incense (ketoret) mentioned in the Old Testament (Exodus 30: 34-36), was actually labdanum.
Labdanum is produced today mainly for the perfume industry. The raw resin is usually extracted by boiling the leaves and twigs. An absolute is also obtained by solvent extraction. An essential oil is produced by steam distillation. The raw gum is a black or sometimes dark brown, fragrant mass containing up to 20% or more of water. It is plastic but not pourable, and becomes brittle with age. The absolute is dark amber-green and very thick at room temperature. The fragrance is more refined than the raw resin. The odour is very rich, complex and tenacious. Labdanum is much valued in perfumery because of its resemblance to ambergris, which has been banned from use in many countries because it originates from the sperm whale, which is an endangered species. Labdanum is the main ingredient used when making the scent of amber in perfumery. Labdanum's odour is variously described as amber, animalic, sweet, woody, ambergris, dry musk, or leathery.
Labdanum oil is used as an alternative of Musk Pod. Musk Pod has been one of the most expensive animal products in the world. Labdanum extract is also used as a flavor additive in electronic cigarette liquid. Particularly in tobacco flavors.
