There are hundreds, if not thousands, of poisonous plants in the world, and some of them are deadly.
Deceptively eye-catching, there are some common plants and flowers that can cause convulsion, give you headaches or simply kill you if you ever try to touch or taste them. So, be careful of what you touch and what you eat.
Despite the plants are extremely poisonous, they are grown either for medicinal purposes or for ornamental purposes. A few of them are grown indoor also but it’s very necessary to keep away from children and pets also.
Here are 10 of the world’s deadliest plants.
1. Kaner (Nerium Oleander)
Oleander is one of the most poisonous of all commonly grown garden plants, and though it’s especially toxic to children it is often planted in school yards.
It is a hearty bush and grows on many different continents, and with beautiful, fragrant blossoms, it is tempting to include it in any garden… just don’t even think about touching it or tasting the leaves or stems.
Members of the genus Dieffenbachia are made up of cells containing microscopic needle-shaped crystals of calcium oxalate called raphides.
When leaves of the Dieffenbachia plant are chewed, these tiny spears of calcium oxalate typically lead to oral irritation, excessive drooling, and swelling.
In rare cases, however, irritation becomes so severe that the tongue, mouth, and throat are effectively immobilized, while tissues become so swollen that the airways are blocked, leading to death.
3. Rosary Pea (Crab’s Eye)
Rosary Peas are the slender perennial climber that twines around trees and shrubs. The seeds of Rosary peas are used as beads. Sometimes, even 3 milligrams of toxin is enough to kill the human.
4. Angel’s Trumpets
Angel’s trumpets are the flowering plants and all parts of the plant possess toxins like atropine and alkaloids scopolamine.
5. Jimson Weed (Datura Stramonium)
People who attempt to consume this weed recreationally for the hallucinogenic properties often get more than they bargain for because it’s nearly impossible not to overdose. In South Africa, they call them “mad seeds.”
6. Castor Beans
Much like oleander, Castor oil plants can be found in houses and gardens all over the world, despite the fact that their seeds are actually very dangerous. So dangerous that, in fact, the plant is the current holder of the Guinness Book of World Records title for world’s most poisonous plant.
7. English Yew (Taxus Baccata)
One of the most deadly trees in the world, these evergreens are common in the forests of Europe. With the exception of the berries, all of the tree is toxic, and the Yew was once used by early herbalists to induce abortions. Sadly, the result was often fatal to both mother and child.
Consumption of the Yew in even tiny amounts causes cardiac issues that result in death. It is quick-acting and there is no antidote.
Monkshood is an outdoor ornamental herb. It is believed that this herb was used by ancient warriors to poison the water of their enemies. Its plant contains poisonous alkaloids which have proved toxic in human body when ingested.
Monkshood is nicknamed as ‘wolfsbane’ as it’s been said that farmers once used this plant to exterminate the werewolves. Monkshood is also known as Leopard’s bane, devil’s helmet or woman’s bane.
9. Deadly Nightshade (Atropa Belladonna)
One of the most toxic plants in the Western Hemisphere, consumption of Deadly Nightshade leads to delirium, hallucinations, dilated pupils, sensitivity to light, blurred vision, tachycardia, loss of balance, etc.
Without receiving the antidote, sufferers will eventually die due to the plant’s disruption of their body’s involuntary activities such as sweating, breathing, and heart rate.
10. Water Hemlock
All parts of Water Hemlock plant contain the alkaloid coniine which causes stomach pains and progressive paralysis. The excessive amount can even take your life. Water Hemlock is also considered one of the most poisonous plants in the history.
It’s believed that the Hemlock is responsible for killing Socrates. People know Water Hemlock by several common names like Poison Parsnip, Devil’s Porridge or Beaver Poison.
