In Aromatherapy, Lavender oil is primarily used to promote relaxation, reduce stress and anxiety, and improve sleep quality, though it also has potential benefits for minor burns, headaches, skin conditions, and nausea when inhaled or applied topically with a carrier oil. The calming scent of lavender oil can be diffused into a room for a tranquil atmosphere or inhaled directly from a tissue or a cotton ball for quick, soothing relief.
