Abstract
Medical aromatherapy aimed at enhancing the prevention and symptomatic treatment of disease is widely used in nursing and the nursing field. It is important that the specific fragrance and its application are selected only after the absorption and mechanism of action of its essential oil are understood. Because it acts on the hippocampus and autonomic nervous system, fragrance stimulation has been considered a complementary and alternative medical therapy for dementia, sleeplessness and sleep disturbance, all of which are related to aging. The in vivo role of free radicals in the development of various diseases has recently been identified. A recent study reported that fragrance use enhanced the elimination of free radicals, and wide application of this modality in complementary and alternative medicine is expected.
