And while none of us think much of this bushy green plant and its little berries, other than to kiss underneath it, many would have us be concerned that the mistletoe is a poisonous plant. Is it?
A bit of botany
The name mistletoe originally referred to Viscum album, also commonly known as European Mistletoe. Found in the wild in Great Britain and large parts of Europe, this particular species isn’t native to North America and doesn’t grow wild here.
Enter Phoradendron serotinum, otherwise known as Eastern Mistletoe — which does grow wild in North America. These are the most common, the mistletoe family contains over 900 species.
Out of the two most common varieties of mistletoe, it’s the European (Viscum album) that is actually a poisonous plant. This doesn’t mean if you’re in the US you should just go wild and start gnawing on the thing.
Unfortunately, unless you’re handy at telling the 900+ species of the mistletoe family apart, I would not suggest consuming it — or letting your pets get too close.
The symptoms of mistletoe poisoning include gastrointestinal distress (stomach pain, vomiting, diarrhea), slowed heart rate and breathing, and other potential health issues.
All is not gloom and doom when it comes to everyone’s favorite holiday kissing spot. According to the New York Times, studies have shown that in hundreds of reported cases of accidental mistletoe ingestion, not one fatality was reported.
Another showed that only a handful of patients showed any reaction to ingesting the plant at all. The species weren’t identified beyond “mistletoe,” so there’s no way to tell if it was the toxic Viscum album or its tame American cousin, but I think you get the point.
The better news: Possible health benefits of mistletoe
Mistletoe has been used in folklore remedies and as a medicinal plant for thousands of years.
