Cedar leaf oil poisoning

 

Cedar leaf oil is made from some types of cedar trees. Cedar leaf oil poisoning occurs when someone swallows this substance. Young children who smell the oil may try to drink it because it has a sweet smell.

This article is for information only. DO NOT use it to treat or manage an actual poison exposure. If you or someone you are with has an exposure, call your local emergency number (such as 911), or your local poison control center can be reached directly by calling the national toll-free Poison Help hotline (1-800-222-1222) from anywhere in the United States.

The substance in cedar leaf oil that can be harmful is thujone (a hydrocarbon).

Home Care

If the person swallowed the oil, give them water or milk right away, unless a provider tells you not to. Do not give anything to drink if the person has symptoms that make it hard to swallow. These include vomiting, convulsions, or a decreased level of alertness.

 

Before Calling Emergency

 

Have this information ready:

  • Person's age, weight, and condition
  • Name of the product (ingredients, if known)
  • Time it was swallowed
  • Amount swallowed

 

Poison Control

 

Your local poison control center can be reached directly by calling the national toll-free Poison Help hotline (1-800-222-1222) from anywhere in the United States. This national hotline will let you talk to experts in poisoning. They will give you further instructions.

This is a free and confidential service. All local poison control centers in the United States use this national number. You should call if you have any questions about poisoning or poison prevention. It does NOT need to be an emergency. You can call for any reason, 24 hours a day, 7 days a week.

 

What to Expect at the Emergency Room

 

Take the container to the hospital with you, if possible.

The provider will measure and monitor the person's vital signs, including temperature, pulse, breathing rate, and blood pressure. Symptoms will be treated.

The person may receive:

  • Blood and urine tests
  • Breathing support, including a tube through the mouth into the lungs, and a breathing machine (ventilator)
  • Bronchoscopy: camera placed down the throat to look for burns in the airways and lungs
  • Chest x-ray
  • ECG (electrocardiogram, or heart tracing)
  • Endoscopy: camera placed down the throat to look for burns in the esophagus and the stomach
  • Fluids through the vein (by IV)
  • Medicine to treat symptoms
  • Washing of the skin (irrigation), perhaps every few hours for several days

 

Outlook (Prognosis)

 

How well someone does depends on how much cedar leaf oil they swallowed and how quickly they receive treatment. The faster medical help is given, the better the chance for recovery.

Delayed injury may occur, including a hole forming in the throat, esophagus, or stomach. This can lead to severe bleeding and infection. Surgery may be needed to treat these complications.
