Aromatherapy is a holistic healing treatment that uses natural plant extracts, also known as essential oils, to promote physical and psychological well-being. It is believed that the aromatic compounds in essential oils can affect the limbic system, the part of the brain responsible for emotions, and trigger positive responses such as relaxation, improved mood, and reduced stress. Aromatherapy can be used through various methods such as inhalation, massage, and topical application.
