10 Deadliest Plants on the Planet Two

Published by nobert soloria bermosa in Science
June 26th, 2008

More plants that are dangerously fatal to humans.

Plants are one of the main sources of human foods and raw materials and medicine as well. Many can be useful but some can be harmful and could be very fatal to humans.

Here’s an additional list of the deadliest plants that had been the caused of death of hundreds of people including animals.

  1. Tree Tobacco (Nicotiana Glauca)

    The tree tobacco is primarily a plant of the southwest. It has been responsible for a number of deaths, usually from eating the leaves prepared in a salad.

  2. Golden Chain or Laburnum (Laburnum Anagyroides)

    All parts of the plant especially the seeds in the pods are poisonous. This plant is native of Europe. Laburnum can be lethal if consumed in excess. Symptoms of Laburnum poisoning may include intense sleepiness, vomiting, convulsive movements, coma, slight frothing at the mouth and unequally dilated pupils

  3. Manchineel (Hippomane Mancinella)

    Manzanilla is one of the most poisonous trees in the world. This species of flowering plant is native to Central America and the Caribbean. The name mancinella is derived from Spanish manzanilla which means “little apple” because its leaves and fruits look like an apple. All parts of this tree including the fruit contain strong toxins. It will secrete a white milky substance during rainfall. It is said that standing beneath the tree during rain may cause blistering of the skin from mere contact with this liquid. Burning the tree may cause blindness if the smoke reaches the eyes. The fruit can also be fatal if eaten.

    The Caribs used the sap of this tree to poison their blowgun darts and were known to poison the water supply of their enemies with the leaves. As a form of torture they would tie victims to this tree and leave them exposed to the elements.

  4. Apple (Malus Domestica)

    Would you believe that part of an apple, one of the worlds most abundant and favorite fruits in the world, is poisonous? The seeds of apple contain cyanogenic glycosides; although the amount found in most apples won’t kill a person, with enough seeds, one could die from it.

  5. Daffodil or Narcissus

    nobert! Another interesting and informative article. The tree tobacco is so beautiful, it’s hard to believe it is deadly and I didn’t know about the Daffodil.

    You always have something I can learn from.

    Nobert,
    You’ve did it again! Another fantastic article!!! I believe I’ll be eating less apples now. I didn’t know apple seeds were poisonous. And to think, apple pie is my favorite pie. Keep up the good work!!!

    The Manchineel tree is native to the US. It exists in southern Florida so perhaps it should be considered the most poisonous plant in the US.

    How is it that when you touch the sap the poison gets into your respiratory system? I think it is very unlikely that your skin would somehow absorb the poison into your blood stream. Otherwise, good post. Some of the pictures look like shoopwork.The pixels are all wrong.

    Are you sure you didn’t just take random photos in your garden and randomly name them by their features? :P

    Joking :]
    but i would like to see some deadly man eating planet, like the daddy Venus fly trap? :]

    Very good article, mine are getting all declined :(

    The word you probably meant to use in the Amanita phalloides section is “STIPE. There is no stripe, but the ’stalk’ of the toadstool is correctly referred to as a STIPE.

    Excellent article!
    I knew about the appleseeds, Sumac, Narcissus and the deathcap.
    On our news recently was a small note of a type of ‘invasive ornamental’ foliage plant that I have seen in yards, and along the Humber river, growing wild. Large leaves like rhubarb, the plant grows to about 1 1/2 meters tall on large’ roundish ’stalks’. In the springtime, the dried leafless ’stalk’ of this plant looks a bit like bamboo. I have plucked these before and examined, eventually discarding the dry hollow ‘walking cane’.
    I should go snap a photograph of this, eh?

    The news article said that people can become temporarily blind from contact with the juices of the plant’s leaves/stalk when green…

    Things that make you go “…whoa!”

    Very informative. Excellent knowledge, however, I STILL don’t think I know how to differentiate a poisonous mushroom, a ‘Death Cap’, what ‘white stripe’, pardon me, but I don’t see that!, from another innocent mushroom. Luckily I don’t care for eating them, but still….
    Overall, great article.

    Ok, the apple seed thing is pretty misleading. Studies have shown that while, yes, apple seeds contain trace amounts of arsenic, one would have to eat nearly a BUSHEL of apple seeds all at once to be affected by the arsenic.

    I have read health books that say to eat all the seeds because they’re good for you. Funny how many contradicting facts there are in health research; it seems 1 scientific study contradicts the rest. Great article with lots of interesting facts.

    Recent studies suggest Podostroma cornu-damae is the most poisonous mushroom in the world.
    Only 3 grams can kill a human and its sap can cause blisters.
    Podostroma cornu-damae is found in China, Japan, Java and a subspecies in Costa Rica.

    I watched a serious documentary TV programme in I think the 70s, possibly panorama relating to a research programme in Edinburgh which was examining the effects of the lack of pectin in the diet of modern western living compared with early humans. It encouraged the eating of pectin e.g.in apple seeds. I already often ate the core along with the rest of the apple but since then I have included the seed, extracting from the core, whenever I have cooked apple for my family. We have eaten an above average quantity. I am still alive beyond my score of years and my children are healthy adults. I don’t know what has happened to those research guinea pigs but don’t worry about apple pips.
