Neroli oil is an essential oil extracted from the flowers of the orange tree, typically bitter oranges. It has a sweet, floral, and citrusy aroma. It is known for its calming and soothing properties, and has been traditionally used to help with anxiety, stress, and insomnia. Neroli oil is also believed to have skin-beneficial properties and may be useful for treating certain skin conditions. It is also used in perfumery as a base note and it's often used as a natural remedy for headaches and migraines. Neroli oil is typically used in aromatherapy, massage, perfumery, and traditional medicine. It is considered safe for most people when used topically in small amounts, but it's always best to do a patch test before using it and to consult with a healthcare professional before using it internally.
