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?

    I’ve heard something about writers writing about guns – if you describe a specific gun they’ll come at you for being wrong, but if you say something like “a modified Kalashnikov” you’re conveying the image you want, and the nerds will do the work for you in figuring out how it could have been modified.

    Arsenic is a classic murder poison. It’s been known since anciemt times, though possibly unsuited to your onset requirement. Acute poisoning by ingestion is generally within a few hours, but if your character sustains lower doses over time, you could probably draw out the timeline to whatever you wanted. It would be obvious that the character is unwell during this time, but the symptoms aren’t super specific and could be confused with e.g. food poisoning.

    Or just invent a mushroom like others said. The toxins are diverse enough that I doubt anyone would be too upset if you tuned it exactly to your timeline and desired symptoms.

    Depending on your setting and desired outcome for the poisoner, uraninite (aka pitchblende) might be an option. It has historical uses in glass making and pottery glazing, which could provide justification for why someone would have it.

    It contains Uranium, which is radioactive, but I don’t believe will bioaccumulate, but can build up on surfaces, tools, and clothing providing a source of long-term radiation exposure. In addition, it contains lead, which does bioaccumulate, providing a source of gradual long term poisoning as well as radium which also bioaccumulates and is radioactive, providing an additional source of longterm radiation exposure.

    Mushrooms are a good option, and you can just make up a species if you want specific time frames/symptoms. Mushrooms can cause a lot of weird symptoms.

    There’s also a brain eating amoeba or other sickness from still water (people back in the day were very aware of tainted water).

    If you have access to polar animals, a unique poisoning would be vitamin A toxicity from their livers. It’s a horrific way to die, though (skin sloughing off).

        Ongoing case here in Australia with a lady accused of murdering her ex and ex-inlaws. Invites them to lunch of beef Wellington and death cap mushrooms.

        3 died fairly awful deaths in the following days/weeks, 1 survived after intensive care.

        Accused of trying to murder the ex 4 prior times too.

        The “Mushroom lady” case absolutely captivated us for weeks

    Apple seeds contain cyanide. You’d have to crush and eat anywhere from 150 to a few thousand seeds for it to be fatal though. I’m sure that hasn’t stopped authors from using it before.

    Go ask chatgpt or something similar for old medical herbs used back in the day that might also posion you. I inspire to write a book one day, and ive found ai to be really informative. The best part is, even if they’re wrong its going in a fiction story(i hope) where it wouldn’t matter.

    • Heavy metals: lead, mercury
    • Arsenic in small doses over a long period

    I don’t know of any plants, but I do know that the leaves of nightshades (potato, tomato, eggplant, capsicum, tobacco) are poisonous toxic in large doses.

    Alcohol. Sometimes it takes 30 or 40 years to be effective. Not very good for murder, but wildly popular for suicide.

      Yeah OP needs to define what “slow” means to them. You could say that a one-week delayed effect is slow. Or you could say that it’s only slow if it takes months of exposure.

    In almost every case in fictional writing it’s better to make up a poison then use a real one. That way you don’t have someone picking it apart later. Also you can give it whatever properties you want/need. Now excuse me while I continue to work on my immunity to iocane powder.

        I’ve never seen anyone even think twice about the Tears of Lys or The Strangler. And after Milk of the Poppy, it’s established that we may expect some similarity to reality in this world.

          Not even that, (in a medieval-fantsy setting) one criticized the use of archer for defense, another wanted for her to write the exact years the events happened… Another one asked why one nation had an italian-sounding name, while the bordering countries had foreign-like names, and different languages!

            that is indeed how you mention someone. Yeah being pedantic for the sale of it isn’t something I understand. Unless it impacts my ability to enjoy the story I couldn’t care less.

          I have read some novels where their history straight up breaks if you think about it for too long. Not saying this happened in this case but I read a fantasy novel that had a history that implied that people existed in the wrong times. Like this person was said to have died in X year yet someone met someone who was born in X+100 years.

          Mental illnesses are very clearly defined, for example in the ICD-10 puplished by the WHO. Pedantry is defnetly not listed in there.

          And yes, this was an attempt of humour.

            defnetly

            That’s a new one.

            And the commonly accepted authority on the definition of mental illnesses is the Diagnostic and Statistical Manual of Mental Disorders. The current edition is referred to as DSM-5.

    Whole maybe not “poisons” by definition I have a couple scary stories of people working in damp, moldy office and basement environments and after a couple years getting rare autoimmune and neurological disorders that killed them. One being my uncle, my family tried to get his workplace to test where he worked because the doctors said that’s most likely where he contracted it, but they refused. We weren’t looking for money, just trying to save the next guy. I was fairly young when this happened so I don’t remember all the details.

    If you want long-term, look to the liver. Alcohol will destroy it over time, but so will viral hepatitis. Have you considered slow acting diseases like hepatitis or HIV? Or something intensely carcinogenic?
