Effect of Inhaled Aromatherapy on Chemo-Induced Nausea Vomiting (NCVI): CINVAROM (Chemotherapy Induced Nausea Vomiting and AROMatherapy)

The investigator wish to provide a blend of two essential oils with comparable antiemetic properties; Peppermint essential oil (Mentha x Piperita) and lemon tree essential oil (Citrus Limon). Dry inhalation of these essential oils is safe, but effectiveness has not been determined. Studies on the subject present a questionable methodology. This is why we are proposing this study to measure the effectiveness of this mixture of essential oils on chemo-induced nausea and vomiting. This study is a first step before a possible study to compare the effects of essential oils with those of a placebo.
