The smell of peppermint often evokes feelings of alertness, focus, and refreshment thanks to its main component, menthol, which stimulates the brain and creates a cooling sensation, but it can also feel calming, mood-lifting, and stress-reducing, helping with focus, nausea relief, and clearing airways, making it a versatile scent for both energy and relaxation. Used in aromatherapy to calm the mind and reduce anxiety.
