Introduction: Medicinal application of plants has been after used for the treatment of different diseases throughout human history. There is an increasing need for antiviral drugs since the treatment of viral infections with the available antiviral drugs often leads to the problem of viral resistance. In the present study, Echinacea purpurea plant with ethnomedical background was tested for its inhibitory effect on HSV-1 multiplication at different exposure times. Materials & Methods: Root part of Echinacea purpurea plant was extracted with decoction method to obtain crude aqueous extract. This extract was screened for its cytotoxicity against Hep II cell line by CPE assay. Antiviral property of the plant extract was determined by Neutralization Test (NT) at one, two and three hours after extract oxposufe following inoculation of HSV-1. Results: Echinacea purpurea plant did not have toxic effect at 50-900 μg/ml concentrations to the cell lines used. Findings indicated that plant extract had the highest inhibitory property when used one hour after virus inoculation that was completely inhibitory for virus replication in concentrations500-900μg/ml, but this anti-herpes specificity decreased in two and three hours. Conclusion: Echinacea purpurea extract exhibited significant antiherpes effect on HSV-1 at nontoxic concentrations to the cell line used. Further research is needed to find action the mechanism of this plant before it could be used in conformation of antiherpes drugs.
