Peppermint

Safety profile

3 studies reporting safety data

Across 3 clinical studies, peppermint (as an herbal extract or oil) was not associated with any increased risk of adverse events compared to control. In 5 quantitative comparisons, no significant differences were found for outcomes such as nausea, vomiting, antiemetic use, and systolic blood pressure. Two additional studies reported the substance as well tolerated, with no serious adverse events and high compliance. While some efficacy signals were noted (e.g., reduced postoperative nausea), the safety profile is supported by a limited evidence base of short-term trials.

Caveats: Evidence is limited to 3 clinical studies, most of which were designed primarily to assess efficacy and may not be powered to detect rare adverse events. Findings reflect specific formulations (peppermint oil) and short-term use; long-term safety and effects in vulnerable populations (e.g., pregnant women, children) are not characterized.
