With the advent of an aging society, the number of elderly people admitted to hospitals or nursing homes has increased. In the medical field, even if various drugs and treatment methods are administered, there are still problems such as loss of appetite, insomnia, and emotional anxiety. In several European countries, the United States of America and Japan, aromatherapy-based adjuvant therapy has been widely introduced, and their governments also passed legislations to formally introduce aromatherapy into hospitals. As adjunctive therapy for orthodox medicine, the scent of aromatic essential oils has improved orthodox medical treatments in hospitals and has been used as a general drug to serve as a treatment method outside the hospital environment. In addition, massage, flower essence therapy and energy therapy (bio-electricity) are added to improve the health of the elderly people, enhancing their emotions, helping them to build confidence, and reducing their sense of loneliness. In recent years, there have been a number of research reports published in various academic journals and special books about the clinical trials of “wholistic aromatherapy.” This article was written by citing several articles, and adding years of personal experiences in natural therapy.
