Alicia Silverstone had fans freaking out over her health ... with some even asking if she was still alive ... after she munched on what they identified as a poisonous berry.
The actress revealed in a TikTok clip Monday she had no idea what the orange berry was that she picked from a random bush in someone's yard during her latest UK adventure. Alicia admitted she'd already taken a bite to figure out it wasn't a cherry tomato ... but gave it another chomp on camera, saying it kinda tasted like a pepper.
Realizing it probably should not be consumed by a human, Alicia gave fans a close-up of the berry ... which they quickly identified in her comments as a Jerusalem Cherry ... warning her it was so poisonous it could be deadly!
According to The Northern New England Poison Center says eating a Jerusalem Cherry -- AKA Solanum pseudocapsicum -- can lead to symptoms like vomiting, diarrhea, drowsiness, hallucinations and heart issues.
While there's been no official word yet on how Alicia’s doing, she did post a few IGs after the video, so it seems she's survived.
