The present study was conducted to investigate the effects of ginger on chemotherapy-induced nausea and/or vomiting. Design: The study was carried out on cancer patients receiving chemotherapcutic agents in the haematology clinic of a training hospital between March 01, 2011 and July 29, 2011. Subjects: The study group was composed of intervention (n=15) and control (n=30) patients. Approval from the ethics committee, informed consent from the patients and permission from the hospital management were obtained. Intervention: Control patients received antiemetic drugs for ethical reasons and intervention patients received ginger tablets (800 mg). Outtome Mea.fure: Data were collected using the Identifieation Form for Descriptive Characteristics, which was prepared by the researchers. SPSS 15.0 was used for data assessment. Results: Statistical analysis revealed no differences in the characteristics of the intervention and control groups (p>0.05). A significant difference was found between the groups receiving ginger and antiemetics, suggesting that ginger is effective for treatment of nausea and vomiting (p<0.05). Conclusion: Results of the present study suggest that ginger is effective for reducing chemotherapy-induced nausea and/or vomiting and they should be confirmed in future studies that include more patients with a haematological cancer.
