Aromatherapy utilizes essential oils extracted from plants to promote physical and psychological well-being. Certain scents, like lavender and chamomile, are believed to have calming effects on the nervous system, reducing symptoms of anxiety and depression. Inhalation of these oils can stimulate the olfactory system, influencing mood and emotions. While aromatherapy may offer relaxation and stress relief, it's not a substitute for professional mental health treatment.
