Don’t eat random fruits off the street. Unfortunately, actress and Clueless star Alicia Silverstone learned this the hard way after eating what she thought was a tomato while walking on the streets of London.

“I’ve just bit into it because it was on the street, and we were discussing whether it was a tomato or not,” Silverstone says in the video while showing off the orange plant.

Silverstone is right that the plant isn’t a tomato. That said, what it actually appears to be is a form of deadly nightshade.

As reported by Queensland Poisons Information Centre in Australia, “All parts of the plant are poisonous, especially the unripe fruits. If plant or fruit is eaten, early symptoms can include fever, sweating, vomiting, stomach pain, headache and increased heart rate. Symptoms are delayed for several hours and can persist for days.”

As Silverstone didn’t eat the whole fruit, she’s unlikely to die from this. But I hope she learned an important lesson about eating fruit off the street — a lesson I cannot believe she needed in the first place. Talk about clueless!
