This is a free and confidential service. All local poison control centers in the U.S. 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.

Expectations (prognosis)

This type of plant may cause severe swelling that blocks the airway, causing breathing difficulties, but this is very rare.
