Aromatherapy is a holistic healing practice that utilizes the natural aromatic compounds found in essential oils to promote wellness of the body, mind, and spirit. It works through the sense of smell and skin absorption, where the essential oils' volatile molecules interact with the olfactory system to trigger various physiological and psychological responses. Aromatherapy can help relieve stress, enhance relaxation, support emotional well-being, and provide symptomatic relief for various ailments.
