It is necessary to develop novel, affordable, and accessible drugs with few side effects as alternatives of the currently available chemical agents for leishmaniasis. Objectives: The main purpose of this study was to evaluate the effects of these drugs on L. major under in vitro conditions. Materials and Methods: In the current study, 5, 10, 25, 50, and 100 µg/mL concentrations of aqueous extract of Artemisia sieberi and chemical artemisinin were tested on promastigotes of Leishmania major (L.

Results: The results obtained for each drug were compared with other drugs and also with the results of the control groups. The results related to promastigote and amastigote assays showed that when the dose of both drugs increased, the parasite number is reduced in comparison with the control groups. Moreover, the parasitic burden in the test cultures decreased significantly. Macrophage assay results showed that the effects of both drugs on uninfected and healthy macrophages were very low. Conclusions: These results indicate that both drugs have anti-Leishmania effects, which was higher in Artemisia sieberi compared with artemisinin. Thus, carrying out further studies on the effects of Artemisia sieberi in infected animals with L. major is recommended.
