Summary

This phase 2 trial tests whether inhaling a blend of peppermint and lemon essential oils can reduce nausea and vomiting in people receiving their first chemotherapy for a solid tumor. Participants will inhale the oils four times daily and whenever nausea strikes, with symptoms tracked over the first days after treatment. The study aims to measure how well this natural approach works as a supportive care option.
