To determine the effects of ginger on chemotherapy-induced nausea and vomiting (CINV) in women receiving adjuvant anthracycline for breast cancer
Patients were randomly assigned to control and treatment groups. Women in the intervention group consumed 500 mg of powdered ginger mixed with yogurt twice daily after an initial dose 30 minutes prior to chemotherapy. Both groups received triplet antiemetic therapy. Patients were followed for five days and were asked to record episodes of vomiting and retching and to evaluate their nausea using a numeric 10-point scale four times per day in a diary. The numeric scale also was used on the first day of chemotherapy to collect baseline data. Patient diaries were collected at the end of the five-day study period.
Randomized, controlled trial
Nausea severity was significantly lower in the experimental group after the intervention on study days 2–5 (p = 0.0001). The number of vomiting episodes also was lower in the experimental group on some study days (p < 0.05).
The use of ginger as an adjuvant to triplet antiemetics among women receiving anthracycline-based chemotherapy resulted in lower acute and delayed nausea severity.
Advances in antiemetic drugs have substantially improved the prevention and control vomiting in the acute and delayed phases of CINV. However, the prevention of nausea has been difficult to achieve. Findings from this study suggest that the use of ginger in combination with triplet antiemetics can be beneficial in reducing the severity of nausea.
