Summary

This study tests whether a peppermint oil mouthwash can help reduce nausea, vomiting, and loss of appetite caused by chemotherapy in people with blood cancers. 72 patients will be split into two groups: one gets standard oral care, the other rinses with peppermint oil three times daily for six days after chemo. Researchers will track symptoms and oral health to see if the peppermint rinse makes a difference.
