Description
Curator's Comment: description was created based on several sources, including: https://www.drugs.com/otc/470846/eugenol-toothache-medication.html | http://www.indepthinfo.com/nutrition/eugenol.htm

Eugenol is sometimes called clove oil because it is the active element in cloves. It causes the aromatic smell typical of cloves and because of this property is often found in perfumes. Eugenol’s properties make it a good local antiseptic and analgesic. It is used in dentist offices to make zinc-oxide eugenol paste for temporary fillings. Eugenol also demonstrates antifungal and antimicrobial activity, showing efficacy against Candida albicans biofilms, Listeria monocytogenes and Escherichia coli. Eugenol is further described to induce reactive oxygen species (ROS) production and to scavenge ROS, thus demonstrating prooxidant and antioxidant effects. Also, Eugenol is used as a pesticide.

Sample Use Guides

Route of Administration: Dental
Eugenol displayed in vitro activity against C. albicans cells within biofilms, when MIC(50) for sessile cells was 500 mg/L. C. albicans adherent cell populations (after 0, 1, 2 and 4 h of adherence) were treated with various concentrations of eugenol (0, 20, 200 and 2,000 mg/L). The extent of subsequent biofilm formation were then assessed with the tetrazolium salt reduction assay. Effect of eugenol on morphogenesis of C. albicans cells was observed by scanning electron microscopy (SEM). The results indicated that the effect of eugenol on adherent cells and subsequent biofilm formation was dependent on the initial adherence time and the concentration of this compound, and that eugenol can inhibit filamentous growth of C. albicans cells.
