Figure 2

Antileishmanial activity of serially diluted concentrations of essential oil from (a) Artemisia herba-alba and (b) Artemisia campestris against L. infantum promastigotes. The activity was determined with resazurin test and monitored after 24 h (dark grey square) and 72 h (grey square) incubation. Results are reported as the means ± SD of three independent experiments carried out in technical triplicate and statistical significance was measured by comparing treated groups to control groups (; insignificant).
