Effect of lavender oil on cell viability. (A) Viability of PBMC cells after treatment with (black bars) or without PHA (white bars) (*P < 0.05, compared to unstimulated control). (B) Viability of unstimulated (white bars) and PHA-stimulated (black bars) PBMC after incubation with increasing concentrations of lavender oil for 48 h, expressed as % of baseline (*P < 0.05, compared to cells without added lavender oil). Results shown are the mean values ± SEM of two independent experiments run in triplicates.
