The woodsy aroma of rosemary may do more than perk up a roast chicken. A small study of 20 people from Moss’ research team at Northumbria University linked rosemary to improved memory and cognition, particularly among older adults.
Lavender is one of the most popular scents in aromatherapy. Studies in both mice and horses have found that the scent of lavender is calming. In humans, small-scale studies found that it might have a modest effect on anxiety.

Tea tree oil is often found in cosmetic products because of its purported anti-microbial and anti-inflammatory properties. When applied to the skin, tea tree oil might be an effective treatment for mild to moderate acne.
