Are poinsettias and mistletoe really dangerous?

Are holiday plants dangerous? What we know

Poinsettias: Are they really poisonous?

Despite their long-standing reputation for being deadly, poinsettias are far less dangerous than many believe. According to Harvard Health and the CDC, this myth originated in 1919 when an unverified story claimed a child died after eating poinsettia leaves. Research, however, has debunked this claim:

A study in the American Journal of Emergency Medicine analyzed nearly 23,000 poinsettia exposure cases and found:

• 96% required no treatment.
• 92% showed no symptoms.

Pets may experience mild stomach upset, but severe reactions are rare.

To put it in perspective, a child would need to eat over 500 poinsettia leaves to experience significant symptoms, making the likelihood of harm extremely low.

Holly berries: The real holiday hazard

Unlike poinsettias, holly berries are more dangerous. The CDC warns that holly berries contain toxic saponins, which can cause symptoms such as:

• Abdominal pain
• Vomiting
• Diarrhea
• Drowsiness

Children are particularly vulnerable, as eating just five berries can lead to symptoms. Adults would need to consume 20–30 berries for similar effects. Keep holly decorations out of reach of both children and pets.

Mistletoe: The facts behind the myth

Mistletoe, often called the "kissing plant," is less toxic than its reputation suggests. While symptoms like nausea and upset stomach can occur, eating a few berries or leaves is unlikely to cause severe illness. However, ingesting large quantities or consuming mistletoe-infused teas can result in more serious effects, such as:

• Gastrointestinal irritation
• Slow heart rate (bradycardia)
• Organ damage in rare cases

Why you should still keep holiday plants out of reach

While poinsettias, mistletoe, and holly are unlikely to cause serious harm, they still pose risks:

• Choking hazard: Berries can fall from these plants and become dangerous for small children and pets.
• Mild symptoms: Even in small doses, ingestion can cause nausea, vomiting, or mild irritation.

What you can do to stay safe this holiday season

Here are a few simple tips to enjoy holiday plants safely:

1. Place plants like poinsettias, mistletoe, and holly where children and pets can’t reach them.
2. Be mindful of fallen berries, which can become hidden hazards on the floor.
3. Consider faux decorations as safer alternatives.
4. If ingestion occurs, consult poison control, a pediatrician, or a veterinarian for guidance.
