Aromatherapy is the use of organic compounds to improve your mood, mental state, or health. Those organic compounds are called essential oils. They’re made from various plant parts, such as roots, seeds, leaves, and blossoms.
How is aromatherapy used to treat depression?
Experts aren’t sure how aromatherapy works. Chemicals in essential oils might trigger smell receptors in your nose that send messages to the part of your brain that controls your mood, suggests the Mayo Clinic.
However, you shouldn’t rely on it alone to treat depression. Instead, consider using it alongside other prescribed therapies.
