      While that's the official reason... Small children cannot chew honey anyway making it also a choke hazard.

      @@Beth_Amphetamine Now that you mention that does sound familiar. If I'm not mistaken the poison comes from the plants and/or animals they live on. An article I just read says that wild-caught frogs can maintain toxicity for some time. Like you said domesticated frogs do not have the poison but depending on the diet they can absorb it, so care must be taken with a caged frog so as to minimize harmful alkaloids. Not harmful to him, to human.

      My home-Ec teacher stressed the danger of killing people with botulism so much that 35 years later I am still afraid to start canning my garden produce. Then the neurologist tells me: “I think the best thing for your migraines is to shoot your head, neck, and face full of botulinum toxin on a recurring basis. Mrs. Schultz would like you to know side effects may include your horrible death.” He may not have phrased it quite that way.

    I'm Swedish and every year (well last year was an exception) people from Thailand come to Sweden to pick blue berries for profit. The problem is that one of our most poisonous mushrooms is very easily mistaken for a mushroom that grows in Thailand - that is edible. Within three days after eating our mushroom the liver stops functioning.

    Another contributing factor to why the Death Cap is so deadly is that, according to people who've eaten them and survived, it tastes kind of sweet therefore causing the victim to eat more of them and ingesting even higher quantities of the poison.

    Strychnine is horrible horrible stuff, we used to use it on the farm to poison gophers and mice and similar little critters. It smells like black licorice and we got ours as a clear liquid. What makes it so horrible is how you die, my dad had a little bit on his hands and after washing his hands way later that day he used his hands to scoop water from the rain barrel to drink, The little bit he had left was enough to have him screaming on the ground seizuring like an epileptic. By the time we got him to the hospital he was almost back to normal so the doc said it must have been a very small amount but to this day he says it's the most painful thing by a factor of 10 that he's ever experienced and really scared the crap out of us kids.

      @peachymeechie1844 4 года назад +3

      Why is that a common thing amongst teachers? And they constantly try to come close to your table in elementary school and get near you and the bad breath almost knocks you over, and then you go home n tell Mom and Dad and they say, "well hunny you'll just have to deal with it! Just look away!" Bwahahahaha!!! What s joke! Especially when they hover over little ones constantly! So you may just wish to tell kids early to spray so ñme cologne or perfume on their sleeve and put it bear their face for comfort. Lol! That's what I did!! I'll never ever forget this old substitute teacher named Mr. Bryant!! He was mean and his breath was kickin' and you could smell him coming! He gets the gold medal 🏅 for the worst breath I ever had to smell! Just straight poopy!! 💩🤢

      Cicuta contains Cicutoxin,which is a non-alkaloidal acetylenic compound. This compound is definitely of lower toxicity than Ricin (LD5O of Ricin is approximately 6 micrograms/kg body weight,injected dose). Cicutoxin has an LD50 of 2.8 milligrams /kg of body weight.,which means it requires about 500 times more Cicutoxin.

      Many plants spread their seeds in other ways. Keep in mind that the fruit of a plant is there to provide extra nutrients for the seed. It just happened that some tasted good to animals, so plants evolved around that and made seeds that could survive digestion.

      @shawnwales696 7 лет назад +5

      It's the seeds of apricots, peaches and apples that contain cyanide, not the fruit, but that doesn't mean that some fruits aren't poisonous. It just depends on the strategy the plant uses to ensure seed dispersal. A plant that depends on animals to eat the fruit and disburse the seeds in a birds guano (AKA chalk, poop etc.) wouldn't be likely to have toxic fruit for example. There is a lot of variety out there, kind of fascinating, don't you think?

    I've no idea why, but that Bulgarian dissident, Georgi Markov, is buried 20 miles from me in a tiny village called Whitchurch Canonicorum... along with Saint Wite.

    I think that umbrellas should be banned, especially assault umbrellas.

      szayel aporrogranz Would you rather be dead and dry-ish or alive and wet-ish. It has been proven that umbrellas can be used as deadly weapons against spies and defectors. In case I'd ever become either, I would feel much safer in a world free of dangerous bumbershoots.

    Very good information. Whilst hunting poachers in Africa I drank water from a hot spring. Long story short, life for me 2 days later was near the end, fortunately I got evacuated. The locals gave me a poison of two drops a day to keep me alive or kill me for a week as an antidote. 3 drops were deadly, these good people knew the poison antidote and one month later I walked again. My blood was later sent to South Africa for Analysis and they suggested a very rare toxic pathogen that I had injested.

    Ricin is being investigated as treatment for cancer? Damn that would've made a great plot twist for Breaking Bad! Imagine Walter White trying to commit suicide using ricin and instead treats his own cancer. He becomes a hero sentenced to death. He killed dozens of people but saved millions with his research on ricin that led to the discovery of a cure. :)
    Man Vince Gilligan you suck at writing endings..

      JunksBv I didn't even spoil anything lol. That's how I would've liked it to end not how it ended.
      With Walter White making a huge breakthrough in science that would save millions of lives. But since he doesn't care much for his own well being it would take her daughter or son to be threatened by a brain tumor to push him to research ricin more seriously.

      Vulcan Hades You said Walter White tried to commit suicide, which I'm pretty sure is the spoiler they're talking about, not the whole ricin curing cancer thing.
