Perillyl alcohol and perillic acid exert efficient action upon HSV-1 maturation and release of infective virus.

Background: Infection by herpes simplex type-1 virus (HSV-1) causes several pathological processes, including cutaneous, oral and genital infections, fatal encephalitis and cognitive dysfunction due to grey matter loss. Acyclovir is the reference compound used as HSV-1 antiviral therapy. However, with the emergence of HSV-resistant strains to current antiviral drugs, development of new antiviral agents with distinct modes of action is urgently needed.
