Plants are the one which helps the Human beings and Animals to live in this World.But Some of the Plants cause death to Humans and Animals.Here I listed top 10 dangerous plants which even kill Human.
1.Castor Plants:
Castor plants are indigenous to the Mediterranean basin, eastern Africa and India, but are widely grown as an ornamental plant. A toxin called ricin is found throughout the plant, but is concentrated in the seeds/beans (which castor oil is made from). One raw seed is enough to kill a human in 2 days, which makes for a long, agonizing and unstoppable death. The first symptoms will be experienced within a few hours and will include a burning sensation in the throat & mouth, abdominal pain, bloody diarrhea and vomiting. The process is unstoppable and the final cause of death will be dehydration.Strangely, humans are the most sensitive to these seeds, as it takes 1-4 to kill a full grown human, 11 to kill a dog and a whopping 80 seeds to kill a duck. The castor plant currently holds the Guinness World Record for most poisonous plant.This plant holds First rank in our list.
2. Belladonna:
Belladonna, also known as Devils berries, death cherries or deadly nightshade, is native to Europe, North Africa and Western Asia. It is also one of the world’s most poisonous plants and it contains Tropane alkaloids, some of which cause delirium and hallucinations. Other symptoms of Belladonna poisoning include loss of voice, dry mouth, headaches, breathing difficulty and convulsions. The whole plant is poisonous, but berries usually play the greatest risk, as they are sweet and tend to attract children. 10 – 20 berries can kill an adult, but it only takes 1 leaf to kill a full grown man.Belladonna holds Second rank in our list.
3. Rosary Pea :
The Rosary Pea, also known as Crab’s eye or Jumbie bead is native to Indonesia, but grows in most parts of the world.The poison contained in the plant (abrin) is very similar to the poison ricin, found in some other poisonous plants but the abrin is about 75 times stronger than ricin. This concludes that the lethal dose is much less, and in some cases as little as 3 micrograms can kill an adult human.This Deadly Plant holds Third rank in our list.
4.Wolfsbane :
Wolfsbane, also known as leopard’s bane, woman’s bane or devils helmet, is a plant belonging to the buttercup family.The plant contains very large quantities of a poison called alkaloid pseudaconitine, which used to be used by the Ainu people of Japan as poison for hunting, on the tips of their arrow heads. In cases of ingestion, symptoms, which include burning in the limbs and abdomen, sets in immediately. In cases of large doses, death can occur within 2-6 hours and 20ml is enough to kill an adult human.Wolfsbane holds Fourth rank in our list.
5. Water hemlock:
Water hemlock is considered to be North America’s most poisonous plant as it is incredibly poisonous to humans.The plants all have very distinctive small white or green flowers, arranged in an umbrella shape. The plants contain a toxin named cicutoxin which causes seizures. This poison is found in all parts of the plant but is most concentrated in the roots, which is most potent in the spring. Besides the almost immediate seizures, other symptoms include nausea, vomiting, abdominal pains, tremors and confusion. Death is usually caused by respiratory failure or ventricular fibrillation and can occur just a few hours after ingestion. Water hemlock holds Fifth rank in our list.
6. English Yew :
The English Yew is a small to medium tree that has seeds enclosed in a soft, red, berry like armor. The berry armor is the only part of the fruit that is not poisonous and this allows birds to eat the fruit and spread the seeds without ill effect. It takes a dose of about 50g to be fatal to a human. Symptoms include difficulty breathing, muscle tremors, convulsion, collapse and finally cardiac arrest. In cases of severe poisoning, death can set in so fast that the other symptoms are missed.This horrible plant holds Sixth rank in our list.
7. Strychnine tree:
The Strychnine tree, better known as poison nut or Quaker Button, is a medium sized tree, native to India and South East Asia. The small seeds inside the trees’ green to orange fruit, is highly toxic, being filled with poisonous alkaloids’ Strychnine and Brucine. 30 mg of these toxins are enough to be fatal to an adult, and will lead to a painful death from violent convulsions due to simultaneous stimulation of sensory ganglia in the spine.This tree holds Seventh rank in our list.
8. Angel’s trumpet :
The name Angel’s trumpet comes from the pendulous trumpet shaped flowers, covered in fine hairs, that hang from the tree. Flowers come in a variety of sizes (14-50cm) and in a variety of colors, including white, yellow, orange and pink. All parts of the plant contain toxins, such as tropane alkaloids scopolamine and atropine.As levels of toxicity varies prom plant to plant, and part to part, it is almost impossible to know how much toxins you have ingested. As a result of this, many users have overdosed and died from it.This Plant holds Eighth rank in our list.
9. Doll’s eye:
Doll’s eye, also known as White Baneberry, is a flowering plant has fruit which is a 1cm in diameter white berry with a black stigma scar, which looks very eye like. Although the whole plant has been declared toxic for human consumption, the most poisonous part is the concentrated toxins in the fruit, which have sadly claimed a number of children’s lives, as they also have a sweet taste. The berries contain a carcinogenic toxin, which has an almost immediate, sedative effect on human cardiac muscles and can easily cause a quick death.This deadly plant holds Nineth rank in our list.
10.White snake root:
White snake root is a highly poisonous plant. Their flowers are white and, after blooming, small fluffy seeds blow away with the wind. This plant has a high % of the toxin tremetol, which is not known for killing humans directly, but indirectly. When the plant is eaten by cattle, the toxin is absorbed into their milk and meat. When humans then, in turn, eat the beef or drink the milk, the toxin enters the body and causes something called milk sickness, which is highly fatal.This Plant holds Tenth rank in our list.
