BACKGROUND: This study is aimed at determining the efficacy of Mentha spicata (M. spicata) and Mentha× piperita (M. × piperita) in preventing chemotherapy-induced nausea and vomiting (CINV).
METHODS: This was a randomised, double-blind clinical trial study. Prior to the study, patients were randomly assigned into four groups to receive M. spicata or M.× piperita. Statistical analysis included the χ(2) test, relative risk, and Student's t-test. Fifty courses were analysed for each group that met our eligibility criteria. The treatment and placebo groups applied essential oils of M. spicata, M. × piperita, or a placebo, while the control group continued with their previous antiemetic regimen. Patients or guardians recorded the number of emetic events, the intensity of nausea over 20 h of chemotherapy, as well as any possible adverse effects that occurred during this time.
RESULTS: There was a significant reduction in the intensity and number of emetic events in the first 24 h with M. spicata and M.× piperita in both treatment groups (p<0.05) when compared with the control and no adverse effects were reported. The cost of treatment was also reduced when essential oils were used.
CONCLUSION: M. spicata or M.× piperita essential oils are safe and effective for antiemetic treatment in patients, as well as being cost effective.
