Compositions comprising propolis, propolis and salicylic acid, or propolis and either a corticorsteroid such as hydrocortisone or a halogenated corticosteroid with or without salicylic acid, are effective in the treatment of warts and in the treatment of herpesviruses. Compositions with corticosteroids are more effective than propolis alone because they reduce inflammation associated with viruses causing warts or herpes eruptions.
