Aromatherapy is an inexpensive and easy therapy to administer to children, and many children can self administer aromatherapy depending on their age and the form of aromatherapy. Aromatherapy has anecdotally been reported to decrease nausea and vomiting, decrease anxiety and increase quality of life in cancer patients. Therefore, the proposed study aims to assess the effectiveness of aromatherapy versus placebo on nausea, vomiting, anxiety and quality of life among pediatric oncology patients receiving emetogenic chemotherapy.
