Abstract

Cutaneous leishmaniasis is one of the important skin diseases with diverse clinical manifestations. With an incidence of 0.7–1.3 million cases annually, this disease is often reported from six countries, including Iran. Accordingly, the purpose of this study was to evaluate the anti-leishmanial effect of the three plant hydroalcoholic extracts including fleawort (Plantago psyllium L.), savory (Satureja hortensis L.) and tarragon (Artemisia dracunculus L.) on Leishmania major promastigotes. The hydroalcoholic extract from each plant was extracted and its anti-leishmanial effect was evaluated in different concentrations (100–1000 µg/ml) and at various hours (24, 48 and 72 h). Savory herb inhibitory concentration 50 % (IC50) at 24, 48 and 72 h was 790.81, 398.11 and 298.42 µg/ml, respectively. In addition, tarragon herb IC50 at 24, 48 and 72 h was 962.03, 688.36 and 585.51 µg/ml, respectively. Moreover, the fleawort extract was showed the lowest effect, considering that its effect at the concentration of 1000 µg/ml was 48 % after 72 h (P > 0.05). Furthermore, the statistical analysis showed a significant difference for interaction between concentration and time regarding the tarragon and savory extracts with a P value of lower than 0.05. According to the results, the anti-leishmanial effect of the tarragon and savory extracts may make it possible to use them in the treatment of cutaneous leishmaniasis as a complementary or alternative therapy; however, further studies are necessary and should be evaluated in cell culture and in vivo conditions to confirm it. © 2016, Indian Society for Parasitology.
