I've actually seen manchineel when I was visiting Mayan ruins in the Yucatan in Mexico. There's actually an orange coloured tree that grows near them that have flaky bark and if you rub it on the sap burn from the manchineel it reduces the pain. There was actually a Mayan legend about two twins, the evil one became the manchineel and the good one became the orange tree to help those who fell victim to his brother.

Their are these red berries called English yew and they made a sticky substance and because it was infront of my elementary school and unless you did an instrument they made you stay outside I'm pretty sure once or twice in rain or snow but yeah so we would throw them and it would stain the whole front floor of the school concrete with red stains but yeah now that I'm in 7th grade i left that school and even moved a town away but my block had the same bush and i have a feature i just discovered on my phone called google oebs which makes it so if you get a picture of something it will tell you what it is and so i did it with the bush on September 19th this year and i finally got the name so the first thing i did was look up why are they sticky and a sixth grader i know asked to look up if they're toxic and so i was like"they probably are not but ok" and turns out 50 grams of the bark or leaves can kill and adult and 1 or 2 seeds can kill a child and i was throwing them at other kids in elementary school (don't worry it was a game we made so 3rd grade me would throw at them and they would throw back making a berry nerf war so we called them berry wars and im serious they were fun also we called them berries because we didn't know the name and i didn't until today)but the flesh or the part you eat is safe and good people say also the seed that is the most toxic part is said to be really tasty like other deadly mushoabd also the water hemlock so I'm 12 and confused how i survived,will still play with the sticky substance and study them though

@a.p907 Год назад

Fun fact about Nightshade: it is also known as belladonna which means beautiful woman in Italian. Since one of the symptoms of its poisoning causes the pupils to dilate, high-class woman would put a tiny amount to dilate their eyes to give themselves a doe-eyed look because it would make them more beautiful (and temporally blind themselves.)

@gorkskoal9315 Год назад

yes! and another (odd) but darkly amusing fact: People used to confuse the flowers from belladnna for tomatoes. I bet they were like: wtf why am I sick! also since forever people have had (hopefully) small amounts to get high, or as a sleep aid. Like: hey barkeep I'll take a nightcap with a side of barfing! can you orange for that please?

@darrellcook8253 Год назад

Yeah they were forced to stay out of the sun because the blinking squinting and tears spoiled the effect. Blindness in older age was much in vogue back then too. Eyes can take only so much.

@statoilbensin2190 10 месяцев назад

Atropine witch is a tropane alkaloid is the chemical that makes you get enlarged pupils. Eye doctor once gave me some atropine and my pupils got so big that it was wery hard to see. The atropine from all I know might have come from a Belladonna or maye a different plant in the nightshade family like Henbane, Mandrake or Datura.

The Manchineel tree is actually quite common in Barbados, they grow along much of the shoreline, my brother and I played with them as kids when we were there visiting family. One of the Bajans noticed what we were doing and told us to stop and wash our hands in the ocean. We were both alright, but it was pretty scary. He kept asking us if we ate any of it and it was obvious that he was concerned. Fortunately, we didn't eat them, but they do look like small apples or quince that aren't ripe.

@goodun2974 4 года назад

There's an interesting book titled The Poisoner's Handbook which is about the history of forensic medicine being developed and used to scientifically determine how and why people died from something they ingested, whether it was an accidental or intentional poisoning. A fascinating read ,especially if you like exploring grim or macabre subjects. Forensic science got a particular boost in funding and research when prohibition led to huge numbers of people being poison from adulterated or badly made bootleg alcohol.

@darrellcook8253 Год назад

The government went on it's own poisoning spree by adding wood alcohol to booze to punish the sinners. Killed an unknown number of people but we know that it was a lot. Numbering in the tens of thousands. Ah fanaticism. And it's alive and well today.

Nightshade is actually quite common. I've even seen some of its greens in bunches of supermarket vegetables, like spinach and chard. Always make sure you check your greens, before cooking. Most outside plants are grasses, but nightshade can easily get in to a commercially harvested bunch.

@studioyokai Год назад

Yeah it's actually invasive in a lot of the USA. The reason it's such a problem? Many birds can safely eat Nightshade berries, and they do exactly what Nightshade wants them to do: spread it all over the place by pooping out the undigested seeds. This can mean a singular plant getting its seeds strewn about for like hundreds of miles. Oops.

The giant hogweed is pretty gruesome too. The sap genetically alters your skin removing its UV resistance and can cause third degree sunburns wherever it had touched. I forget how long the effect lasts. It might be seven or ten years. England waged a very expensive and ineffective war against it. Also in Wisconsin, if a person sees it, they are supposed to call the DNR who will come and try to destroy it. It likes cold wet places like river banks and originally came from Russia.

I imagine a giant herbivorous dino, like a sauropod, eating it, getting the roaring shits, and the seeds would be in their dung and it would get widely dispersed. And if the animal didn't die, it would probably be smart enough to not eat it again. A sauropod herd could wipe out an entire forest in one day so being a poisonous tree would be very handy.

@rndeto 6 лет назад

Some plants are poisonous to humans but not other animals. Poison ivy berries would cause swelling in the throat of a person who ate them but birds are immune and its an important fat source for them during migration. Other plants might use different ways to disperse, such as wind or water, so their toxicity is incidental.

Oleander was planted in the middle median along Highway 101 in S.F. Bay Area. That’s the best place where no one can get to them. A farm near me had planted them around the property away from any farm animals. Well, they had inexperienced landscapers to clean them up. They had thrown them in a cow pasture not knowing they were poisonous and about 30 cows died. It was sad to drive by and see the cows there in the pasture until they were removed.

Yeah, I vividly remember getting into an argument with my younger brother about whether a plant growing in the garden was a blueberry. I think he was about 4 or 5, so I would have been around 9 or 10. I was sure it wasn’t (we did u-pick blueberries every year, so I was pretty familiar with blueberries), he insisted they were. So I called Mom in on the argument, and it turned out that it was, in fact, nightshade. It made a big impression on me, it hadn’t occurred to me that the plant was in any way dangerous, I was just sure it wasn’t a blueberry. To this day I’m very wary of eating any plant I can’t definitively identify.

Manchineel trees grow throughout the Southern Caribbean along the beaches, but usually they are labeled. Dumb Cane is called that because the stalk resembles cane if you take off the leaves. My grandmother told me that in the old days if you were working (farm worker) the land and someone kept stealing your food and you wanted to know who it was you would purposely contaminate your lunch and the person who ended up w a swollen tongue and a bunch of blisters and couldn’t talk was the culprit hence the name Dumbcane.

Aconite has some lovely flowers. I got some plants at a greenhouse and they grew well, but always had skin irritation after weeding that flower bed.

Because they're also useful. Monkshood, when properly prepared, can help treat some medical problems. However, you need training to learn how to prepare it so that it won't poison you or anyone else. I believe it's also an antidote to some other poison, oddly enough.

A couple of the local trees around me are the Karaka: [Wiki] "poisoning would result with symptoms including violent convulsions and severe muscle spasms which could leave the limbs permanently fixed in contorted positions". When in season is often in the local news; killing dogs who eat the fruit. Another is the Tutu: [Wiki] "It acts as a potent antagonist of the glycine receptor,[1] and has powerful convulsant effects". According to the local natives it can easily kill if ingested.

@bearsbeetsbattlestargalactica8 Год назад

Why are you surprised you havent been poisoned yet if you say youve never eaten them? The only way 2 be poisoned by them is by eating the plant or using it as kindling 4 a fire and breathing in a decent amt of smoke (or eating a fair amt of food that was cooked over that fire) You have to eat a LOT of oleander to end up dead, thats why its NOT a popular murder poison. Simply touching or smelling it isn't gonna hurt you according to another video. That's why it's still a popular flower in gardens despite being potentially toxic.

Deadly nightshade may look like blueberries, but it looks even more like Common nightshade(to which it is related), which has edible fruit. Don't confuse them. Common nightshade grows in bunches of several fruit, deadly nightshade generally grows berries individually along the plant.

@7phyton 3 месяца назад

There are two completely different plants called "deadly nightshade" and one of these, which grows in a lot of the US, does in fact have berries in bunches. Presumably the commenter means "black nightshade" in mentioning an edible fruit. But it's not very edible; toxic in many plants of the species but probably not fatal. Learn your botany before you eat any wild plants.
