Background: Cumin (Cuminum cyminum L. [family Apiaceae])seed essential oil is reported to have antiseptic activity.Until now the antiviral properties of cumin seed extracts onviruses such as herpes simplex virus-1 (HSV-1) have not beenstudied. The objective of this study was to investigate the invitro effects of aqueous, methanolic and hydroalcoholic extractsof cumin seed on HSV-1 growth in Vero cell line.Methods: Antiviral activity of various concentrations aqueous,hydroalcoholic and methanolic extracts of cumin seed in Verocells were studied using plaque reduction assays. The 50%cytotoxic concentration (CC50), 50% inhibitory concentration(IC50), and therapeutic index of the effective extracts were calculated.Results: Methanolic extract of cumin seed showed a significantantiviral activity on HSV-1 in Vero cell line. Its CC50 forVero cells, IC50 and the therapeutic index for HSV-1 were0.45, 0.18 mg/mL and 2.5, respectively. Aqueous and hydroalcoholicextracts of cumin seeds showed no inhibitory effecton HSV-1.Conclusion: The methanolic extract of cumin seed producesanti-HSV-1 effect. Probable interference of phenolic compoundswith fusion of Vero cell membrane and HSV-1 envelopemight be the mechanism of such inhibitory effect. Furtherstudies are required to ascertain its in vivo antiviral propertiesand potential toxicity.Iran J Med Sci 2010; 35(4): 304-309.
