The Full Story
The poinsettia is well known for its bright red and green colors. It is a very common household plant, especially around the winter holidays. The plant was first discovered in Mexico and brought into the United States by the first minister to Mexico, Dr. Joel Poinsett.
This festive plant is not deadly, but some stories just won't go away. Over a hundred years ago, a child was found next to a wild poinsettia plant. He died and people blamed the plant. This hasn't happened since. Researchers even tried to find out what the poisonous dose of poinsettia might be and they just couldn't, even after reaching experimental doses of about 1.25 pounds (500-600 leaves). The plant does not have dangerous effects when eaten.
In most cases, exposure to any parts of the poinsettia plant in children or pets has very little if any effect. If swallowed, it may cause mild irritation: nausea, vomiting, or diarrhea. Touching it may cause a rash. There have been reports of gardeners who work with the plant frequently developing a rash from handling the plant.
So, you don't have to completely eliminate the plant from your home. After all, it makes for a great holiday décor. But you still should prevent your child or pet from swallowing it by storing it out of their reach. It can pose a choking hazard. And, it is always nice to avoid having to deal with nausea, vomiting, diarrhea or a skin rash.
