Outcome Measures
Primary Outcomes (1)
Resolution of Postpartum Urinary Retention
Spontaneous bladder voiding of at least 150 milliliters
within 10 minutes after administering study intervention
Secondary Outcomes (3)
Time to resolution of urinary retention
Within 6 hours of postpartum urinary retention
Volume of urine voided
Within 6 hours of postpartum urinary retention
Patient Satisfaction Level

Study Arms (2)
Peppermint Oil Vapor
ACTIVE COMPARATORExposure of the perineum to the vapor of the active comparator, 2 ml peppermint oil. The perineum will NOT come into contact with the oil directly.
Mineral Oil Vapor
PLACEBO COMPARATORExposure of the perineum to the vapor of the placebo comparator, 2 ml mineral oil. The perineum will NOT come into contact with the oil directly.
Interventions
2ml of the oil will be placed in the urine collection "hat" that fits into the bowl of the toilet. Participants will then sit on the toilet in normal fashion, exposing their perineum to the vapor of the oil. The perineum will NOT come into contact with the oil directly - only the vapor from the oil will contact the perineum.
