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 health care provider will measure and monitor the person's vital signs, including temperature, pulse, breathing rate, and blood pressure. Symptoms will be treated as appropriate. The person may receive breathing support and fluids through a vein (IV).
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.
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.
