The N.Y. Times reports that mistletoe is not quite as hazardous as it is made out to be. The plant contains harmful chemicals like viscotoxins, which can cause gastrointestinal distress, a slowed heartbeat and other reactions.

But in studies of hundreds of cases of accidental ingestion over the years, there were no fatalities and only a handful of severe reactions. One study published in 1996 looked at 92 cases of mistletoe ingestion and found that only a small fraction of patients showed any symptoms. Eight of 10 people who consumed five or more berries had no symptoms, and 3 of the 11 people who consumed only leaves had upset stomachs.

Other studies have found similar effects, suggesting that while mistletoe can be toxic, its lethal reputation is not quite deserved.

But, like poop, don’t eat it.
