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.

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

    What do you mean by slow? Time till symptoms? time till death? Hours? Days? Weeks?

    Raw castor beans contain ricin its a cool looking plant that gets big. My neighbor grew on once accidentally.

    symptoms commonly begin within two to four hours, but may be delayed by up to 36 hours.

    Unless treated, death can be expected to occur within 3–5 days; however, in most cases a full recovery can be made.

    Actually a lot of beans are toxic when raw, but not deadly. Raw lima beans are special though; they contain something that the human body breaks down into cyanide. No clue how long that takes or how many it would take to cause harm.

    Heavy metals (mercury, arsenic, cadmium, lead) are known for building up over time with many exposures. Think mad hatter syndrome, etc. but exposures can also be acute if high enough. IIRC acute arsenic poisoning makes you vomit and diarrhea until you die of dehydration after days or weeks.

    As a writter you should get enough details wrong that someone trying to follow your recipie fails. Ideally they are also caught.

    Yeah, in a historic setting, use something readers will recognize, as well. Arsenic, Mercury, that kind of thing. They’ve been used as a poison, and have accidentally poisoned, for so long that they’re tropes of their own. Both of those in specific were available in the region you’re using.

    Plus, they’re going to be really easy to describe the actions of, and don’t require medical knowledge to understand the effects of. Well, the stuff that’s going to be useful to show on page anyway, the stuff that happens inside organs might take a little.

        all metals that bind to sulfur well are to some degree poisonous. these are lead, mercury, thallium, some platinides (in salt form), arsenic, and also copper, but less than others. some metals have other mechanisms of toxicity, like nickel, hexavalent chromium, cadmium, beryllium or barium. some of these accumulate in brain or bones, and some don’t. some are more toxic when inhaled like zinc or chromium

        Yes, but not as much as many other metals. We’retalking large amounts over a long period of time.

        On sidenote, everything is poisonous, it’s just a matter of dosage.

        Over time most metals can build up in your body if they’re not in a compound your body can process.

        Copper, lead, cadmium etc - it’s difficult for your body to expell them so they build up in your tissues

    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.

    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.

    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.

    Mushroom poisons usually are slow actors. They take a few days while they kill your liver, and then you’ll follow suit.

    For that i think having a read about acqua tofana would be a pretty good source of inspiration, since it was designed to have effects like an illness. it originates in italy so most of it’s ingredients are by default from a mediterran climate.

    Or if you want something natural without too mutch human processing, belladonna is a surefire, but not slow acting.
