- Breathing support, including tube through the mouth into the lungs and breathing machine (ventilator)
- Chest x-ray
- EKG (electrocardiogram, or heart tracing)
- Fluids through a vein (by IV)
- Laxative
- Medicine to treat symptoms

Outlook (Prognosis)
How well someone does depends on the amount of peppermint oil swallowed and how quickly treatment is received. The faster medical help is given, the better the chance is for recovery.
Survival past 48 hours is often a good sign that recovery will occur. If the kidneys are damaged, they may take several months to heal. Long-term injury to the lungs can also occur.
