The Claim: Holly and Its Decorative Berries Can be Deadly (Published 2008) (2024)

THE FACTS

Like mistletoe and poinsettia, holly is prized for its beauty and feared for its rumored toxicity. But studies show that much like its two Christmas companions, holly is not quite as deadly as portrayed. Its berries, which contain a caffeinelike alkaloid, might cause irritation, but a fatal ingestion is unlikely.

According to a one study by the Children’s Hospital of Pittsburgh, plant exposures are the fourth most common cause of poisoning in the country. Ingestion of holly is among the five most common when it comes to plants.

A study by researchers at the University of Rochester reviewed 103 cases of toxic berry ingestion over two years, all involving children who swallowed six or fewer berries of holly, yew or nightshade. The children who were given ipecac experienced vomiting, diarrhea and “sedation.” The others, who were simply monitored closely, did not, suggesting that symptoms attributed to holly and other berries might be a result of ipecac. When accidental ingestion occurs, scientists said, it is best to consult a poison control center. But no need to banish that bough of holly.

THE BOTTOM LINE

Holly may be problematic, but it is not as toxic as widely believed.
