9. Lemongrass
Lemongrass is a natural way to cope with stress and nervousness. Its fresh aroma is associated with the countryside and nature. Dr. Hirsch points out, though, that lemongrass is unlikely to cause any special chemical reaction in the brain. It’s all about images people get when they breathe in herbal scents or drink herbal teas.
10. Jet Fuel
That’s quite unusual yet not less curious to find out that the scent of jet fuel can make us feel happy and relaxed. Once we smell jet fuel we start looking forward to a trip. Whether it is a plane or a yacht, we want to run away from out daily routine to some distant land where “troubles melt like lemon drops”.
