Applications of Volatile (Essential) Oils in Human Health: Cosmetic and Dental Applications

Abstract

Essential oils (EOS) or volatile oils are secondary metabolites produced by aromatic plants. They are obtained from diverse parts of these plants (leaves, seeds, berries, flowers, wood, peels, etc.) by different extraction processes. Their uses date back to ancient cultures who bequeathed to us their knowledge about EOs benefits. Several studies have reported their promising potential applications in human health due to the various and helpful properties of phytocompounds. In this chapter, some utilizations of EOs and their components in cosmetic and dental applications are discussed. Particularly, their anti-inflammatory and antioxidant properties which are very advantageous for the cosmetic industry to neutralize free radicals and prevent lipid peroxidation of cell membranes. On the other hand, the use of EOs in dental applications are mainly linked to their antimicrobial properties, useful in preventing infections and their ability to form polymeric nanofilms on dental implants with proven antibacterial properties.
