Introduction & Objective: Leishmaniasis is a disease caused by intracellular protozoa parasites of the genus Leishmania and is endemic in some areas of Iran. Echinacea purpurea is a native plant from North America which is one of the most important medical herbs known with immuno-stimulant properties. This study was performed to determine the effect of alcoholic extract of Echinacea purpurea on prophylaxis and treatment of Leishmania cutaneous lesions. Materials & Methods: In this experimental study which was conducted at Shiraz University of Medical Sciences in 2009, eighteen mice were divided into 3 groups. Group one received Echinacea purpurea extract (200 mg/ml) in their water, for 2 weeks before parasite injection, while group two were first injected with parasite amastigotes, followed by administration of Echinacea purpurea extract for 2 weeks. Group three was the control group, which received parasites, but not the extract. The size of Leishmania lesions in the tail base, right and left foot were measured with vernier caliper. The lesion areas were calculated and the collected data were analyzed with SPSS software. Results: The mean of lesion size in each group of mice were compared and analyzed. No significant differences in the lesions size were found between the three mice groups. Therefore, Echinacea purpurea extract was not effective against Leishmania major based on the findings of this study. Conclusion: Our findings suggest that Echinacea extract is not effective in treatment or prophylaxis of leishmaniasis in mice. Yet, further studies are needed to determine the effects of other extracts of this plant.
