The present study aimed at evaluating the anti-Trichomonas effect of essential oil and that of nano-emulsion of Rosmarinus officinalis on the growth of Trichomonas vaginalis (T. vaginalis) in vitro. Materials and methods: T. vaginalis reference strains were cultured in modified TYM medium. The components of rosemary essential oil were determined by gas chromatography. In addition, cytotoxicity effects of essential oils and nano-emulsions prepared from this plant were evaluated against macrophage cell line (J774.A.1). Serial concentrations of 10, 25, 50, and 100 (μg/mL) were prepared from rosemary essential oil and nano-emulsion. Then growth inhibition rate of the parasites in different concentrations was done in triplicate within 1, 2, and 3 hours. Results: Rosemary essential oil and nano-emulsion had an inhibitory effect on the growth of Trichomonas and concentration of 100 μg/mL showed growth inhibition effect of 96.1% and 100% throughout 1,2 and 3 hours, respectively. Additionally, cytotoxicity assay against macrophage revealed no toxicity on the cells at 100 μg/mL. Conclusion: According to the suitable anti-trichomonas activity of rosemary, this plant could be considered as a good candidate in treatment of Trichomonas infection, after complementary studies on animal model.
