Effect of lavender oil on tryptophan metabolism. Effect of lavender oil on the kynurenine to tryptophan ratio (Kyn/Trp; A), kynurenine (B) and tryptophan (C) concentrations in unstimulated (white circles) and PHA-stimulated PBMC (black triangles), expressed as % of baseline (control cells treated with or without PHA). Tryptophan concentrations are expressed as % of medium control. Results shown are the mean values ± SEM of four independent experiments run in duplicates (*P < 0.05, compared to baseline).
