How Poisoning Can Happen

House plants are beneficial and can help clear the air, soothe our minds, and add beauty to a room but not at the expense of your children or pets getting sick and possibly dying.  You should keep plants up out of the reach of children and pets but this not always possible.

You can get poisoned by:

  • Ingesting blossoms, roots, or berries
  • Touching or eating the leaves
  • Skin contact with juices or sap
  • Drinking water from the plant tray
  • Eating the soil

While some of these reasons seem extremely bizarre, people may have done these things.
