Prevent Plant Poisonings

  • Know the names of all your plants indoors and outdoors. Label your plants so they can easily be identified in case of poisoning.
  • Keep all house plants out of reach of young children
  • Berries are particularly attractive. Teach children never to put berries or any part of a plant in their mouths.
  • Never assume a plant is non-toxic because birds or wildlife eat them
  • Do not rely on cooking to destroy toxic chemicals in plants
  • Teas and infusions made from plants can also be a source of poisoning
