And before anyone makes a cheeky “what do you need this for 🤨” comment, I’m a writer. I’m not going to murder anyone I promise, I just want to write a scene where one guy gets poisoned.

I need something that doesn’t require modern technology to extract/produce, and would make sense to be avaible in a place with a temperate to mediterranean climate. The slower, the better. Does a plant or something like that exist or do I need to make one up?

Update: I looked into death cap mushrooms and they might be just what I’m looking for! Long reaction time, and being dried doesn’t make them less toxic! (the scene takes place in midwinter so no fresh ones would be avaible) If anyone has more info on them, please do share.
