Aromatherapy is not new; it’s been used for thousands of years to influence the brain. So, invoke the power of scent to fight stress, to spur stamina or to lighten a mood. Peppermint, ginger, cinnamon, nutmeg and lemon are energizing scents that help fight fatigue and boost energy. Tension-taming scents that soothe and relax include honeysuckle, myrrh, patchouli and lavender.
