Here’s what to do if you think someone has been exposed to a poisonous plant.


Some plants can cause itching, blistering, or a rash when the plant or its sap comes into contact with skin.

  1. Take off any soiled clothing
  2. Rinse the skin under running water for 15 minutes. Wash the skin gently with soap and water. Rinse again.
  3. Call PADIS (Poison and Drug Information Service) at 1-800-332-1414 (Alberta)


If the person rubs their eyes after touching the plant or if a splash of plant sap gets in the eyes, the eyes may become irritated.

  1. Rinse the eye for 15 minutes with lukewarm water poured from a large glass 5 cm to 7.5 cm (2 to 3 inches) above the eye.
  2. Have the person blink as often as possible while rinsing the eye. Don’t force the eyelids open.
  3. PADIS (Poison and Drug Information Service) at 1-800-332-1414 (Alberta)


Choking is the first concern when a child puts any plant part in his or her mouth. A piece of the plant may get stuck in the child’s throat and block the airway.

  • If you can see the plant, take it out. If you can’t, don’t stick your finger down the child’s throat to feel for it.
  • Check the mouth for any irritation, swelling, and change in colour. Check if the child is having trouble swallowing.
  • If the child isn’t having trouble swallowing, give half a glass of water or milk.
  • Don’t force vomiting.
  • Don’t wait for symptoms to show.
