Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

A randomized controlled study will be conducted, with two arms. Postpartum women experiencing urinary retention will be randomized into one of the two following arms:

* Arm 1: Subjects will be exposed to vapor of peppermint oil
* Arm 2: Subjects will be exposed to vapor of placebo (mineral oil) Outcome variables include resolution of urinary retention, time to spontaneous urination, volume of spontaneous urination, frequency of urinary catheterization, and patient satisfaction.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The purpose of the study is to determine if the use of peppermint oil among postpartum women experiencing urinary retention will increase spontaneous urination and decrease the need for catheterization. A randomized controlled study will be conducted, with two arms. Subjects will be randomized into one of the two following arms:

* Arm 1: Subjects will be exposed to vapor of peppermint oil
* Arm 2: Subjects will be exposed to vapor of placebo (mineral oil) Outcome variables include resolution of urinary retention, time to spontaneous urination, volume of spontaneous urination, frequency of urinary catheterization, and patient satisfaction.
