Chapter 74 – Rockroses (Cistus sp.) Oils
Abstract
Cistus plants, also known as rockroses, are a Mediterranean native genus of shrubs included in the Cistaceae family. The Cistus genus contains 25 different species and most of them are very fragrant and sweet-smelling. All Cistus
 species secrete essential oils in different amounts which are mostly 
composed of monoterpene, sesquiterpene, and diterpene compounds, but not
 all of them are fully characterized. Several Cistus species 
also secrete “labdanum,” a sticky exudate covering leaves and stems 
mostly in summer, which shares terpenoid composition with the essential 
oil. Several reports have noted significant antioxidant activity and 
potential antimicrobial activity of Cistus essential oils 
against a wide variety of bacterial and fungal infections, which is 
probably due to presence of terpenes. The use of some of these essential
 oils has been approved in low concentrations as flavoring agents. 
Nevertheless, due to potential reported side effects, safety assessment 
studies must be conducted in order to use these materials for food 
preservation purposes.
