The antiviral activity of the aqueous extract of Phyllanthus orbicularis, a member of the Euohorbiacea family, against the simple herpes virus type1 was evaluated in cellular culture, specifically in fibroblasts of human prepucium, and in an animal model, Balb-c mice. The extracelullar effect of the extract on HIV-1 proved to be effective. A selective index of 44 was obtained, which shows a possible virucidal action on the particle. In the trial in vivo, the topical administration of the aqueous extract (12 mg/kg) reduced significantly the development of lesions in mice subcutaneously infected with HIV-1 (1 x 106 UFP). These results suggest the consideration of Phyllanthus orbicularis as a possible anti-HIV-1 candidate
