  1. Results are means of three different experiments.
  2. aDD: Disc Diameter of inhibition (halo size) in millimeters, Essentiel.oil 100 μg/disc.
  3. bMIC: minimum inhibitory concentration (in micrograms per milliliter).
  4. cIC50: 50% inhibition concentration (in micrograms per milliliter).
  5. dDD: Cycloheximide (10 μg/disc), was used as positive controls for fungi.
  6. NA: no active.
