Abstract Eugenol (4-allyl-1-hydroxy-2-methoxybenzene) was tested for antiviral activity against HSV-1 and HSV-2 viruses. In vitro, it was found that the replication of these viruses was inhibited in the presence of this compound. Inhibitory concentration 50\% values for the anti-HSV effects of eugenol were 25.6 microg/mL and 16.2 microg/mL for HSV-1 and HSV-2 respectively, 250 microg/mL being the maximum dose at which cytotoxicity was tested. Eugenol was virucidal and showed no cytotoxicity at the concentrations tested. Eugenol-acyclovir combinations synergistically inhibited herpesvirus replication in vitro. Topical application of eugenol delayed the development of herpesvirus induced keratitis in the mouse model. Copyright 2000 John Wiley & Sons, Ltd.
