First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tested whether breathing in peppermint oil vapor could help new mothers urinate on their own after childbirth, reducing the need for a catheter. The trial enrolled 77 postpartum women who were unable to urinate within six hours of delivery. Participants sat on a toilet with peppermint or mineral oil vapor in the bowl. The study was terminated early, so firm conclusions are limited.
