From: Lavender oil suppresses indoleamine 2,3-dioxygenase activity in human PBMC
Effect of lavender oil on neopterin production. (A) Concentration of neopterin in unstimulated (white bar) and PHA-stimulated PBMC (black bar) (*P < 0.05, compared to unstimulated control). (B) Neopterin concentrations expressed as % of baseline (control cells treated with or without PHA) in the supernatants of unstimulated (white circles) and PHA-stimulated PBMC (black triangles), incubated with increasing concentrations of lavender oil for 48 h. Results shown are the mean values ± SEM of four independent experiments run in duplicates (*P < 0.05, compared to baseline).
