Background: Viral infections are among the most common problems in health-care practice. Natural products offer great promise as potentially effective antiviral drugs. Propolis is a honeybee product with biological properties and therapeutic applications. We aimed to investigate the antiviral activity of different extracts of Standardized Propolis Preparations (M.E.D.(R)) with glycol, ethanol, glycerol and soya oil, against herpes simplex type-1 (HSV-1) and type 2 (HSV-2) viruses.
