Home Care
Wipe out the mouth with a cold, wet cloth. Rinse the person's eyes and skin well if they touched the plant.
Give the person milk, unless instructed otherwise by poison control or a health care provider. DO NOT give milk if the person is having symptoms (such as vomiting, convulsions, or a decreased level of alertness) that make it hard to swallow.
Call poison control for more guidance.
Before Calling Emergency
Get the following information:
- Person's age, weight, and condition
- Parts of the plant that were eaten, if known
- Time 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 plant with you to the hospital, if possible.
The provider will monitor the person's vital signs, including temperature, pulse, breathing rate, and blood pressure. Symptoms will be treated as needed. The person may receive fluids through a vein (IV) and breathing support. Damage to the cornea will require additional treatment, possibly from an eye specialist.
Outlook (Prognosis)
If contact with the person's mouth is not severe, symptoms usually resolve within a few days. For people who do have severe contact with the plant, a longer recovery time may be necessary.
In rare cases, swelling is severe enough to block the airways.
DO NOT touch or eat any plant with which you are not familiar. Wash your hands after working in the garden or walking in the woods.
