There is something to aromatherapy. Essential oils are full of molecules that look like drugs and bind to GPCR receptors in the nose that head to the brain and have all sorts of effects, even if these molecules don't transport well in the body or cross the blood-brain barrier. Peppermint as a scent is usually thought of as stimulating, raising heart rate and blood pressure. The lore, with some research supporting it, is that other oils that are more sedating can bring down blood pressure if you use them, say, in a diffuser. https://pmc.ncbi.nlm.nih.gov/articles/PMC3521421/ https://pmc.ncbi.nlm.nih.gov/articles/PMC3521421/ I find the sensuality of Ylang Ylang to be distracting so I mixed in Lavender and got this wonderful floral smell that filled my office but an hour later I notice the sedation and I am nodding off and can't concentrate on work at all. It was like the scene in the Wizard of Oz where the Wicked Witch of the West put (most of) the protagonists to sleep with a field of scarlet poppies.
