PLANT PLANTS AROUND OUR MOST DANGEROUS

The plant is a plant lacking chlorophyll and can produce its own energy from the photosynthesis that occurs in the green part daun.Walaupun, there are several plants that produce a product that turned out to be harmless to humans and other living things. Toxins are removed and the plant is a secondary reaction is the reaction of the defense system of the plant.By removing these toxic plants can continue to exist to this day. The following are the most dangerous species.

1. Nepenthes attenboroughii

Found more than 5000 meters above sea level on Mount Victoria in the Philippines, the giant, meat-eating pitcher plants secrete substances like nectar to lure prey unexpected into the pool of enzymes and acid. A series of sticky, downward ribs makes it nearly impossible for trapped prey to escape. The 30-cm diameter plant large enough to trap pesky rats, but the most common eating insects. Pitcher plants, of which there are about 600 different species, tend to grow in nitrogen-deficient environments, and therefore obtain nutrients from decaying victims.

2. Ricinus communis

Castor-bean plants can be purchased at almost any garden center, despite containing the deadly poison ricin. Amy Stewart, author of Wicked Plants and poisonous plant expert, has an affinity for plants grown in the garden and some poison her. Concerned gardeners can simply pluck the seeds of the plant, Stewart said, which is where the ricin is stored. Although the process to extract enough ricin and process into weapons complex, Las Vegas authorities have discovered the toxin in a hotel room in February 2008, and the KGB used to permanently silence opposition.

3. Cicuta douglasii

Regarded as "poisonous perennials that grow in North America" ​​at the USDA, the water hemlock contains the toxin cicutoxin, which wreaks havoc on the central nervous system, causing grand mal seizures-which include loss of consciousness and violent muscle contractions and eventually death, if ingested . Water hemlock is different from poison hemlock, Socrates' notorious killer, in that it contains coniine alkaloids that kill by paralyzing the respiratory system. Both are members of the carrot family.

4. Eupatorium rugosum

Drinking milk from cows that decided to chow down on white snakeroot can cause deadly milk sickness, as well as Abraham Lincoln's mother Nancy Hanks. Every part of this plant contains tremetol, an unsaturated alcohol that can cause muscle tremors in livestock before killing them. "People are trying desperately throughout the 19th century to figure out what is poisoning their animals," said Stewart. It was not understood until the turn of the century, when the U.S. Department of Agriculture quickly pointed the cause and get the word out. Now, white snakeroot still grows wild, but more control in the agricultural industry have helped to prevent cows from eating.

5. Aconitum napellus

Stewart was once asked what the best plants will kill-after dinner guest with much deliberation she landed on monkshood. "You can only cut the roots and make soup," he said. "You do not need a chemical plant to do so." The vibrant purple plant, commonly found in the backyard garden, loaded with poisonous alkaloid aconite, which tends to cause shortness of breath. While Stewart would joke about cooking up a batch of monkshood stew, she urges anyone who has a plant in their gardens to wear gloves when handling it.

6. Utricularia macrorhiza

This aquatic meat eater relies on several submerged bladders to capture prey such as tadpoles and small crustaceans. An unsuspecting passerby will brush against an external trigger hairs, causing the bladders to spring open and capture it.Once inside, the victim died from suffocation or starvation and then decays into a liquid being sucked up by cells in the bladder wall.

7. Dionaea muscipula

With the ability to clamp shut in half a second, Venus flytrap reaction time seems appropriate for the animal kingdom.Insects need to touch the hair flytrap's two in a row in order for the plant to react, but the exact mechanism remains unclear trap shut. Communities United Kingdom notes that early theories suggested that a sudden change in water pressure triggered cell responses, but this theory has since been abandoned. Now it seems that when the plant is touched, altered leaf electric potential, triggering a number of cellular-level events.

8. Brugmansia

The, gloomily beautiful angel trumpet, native to regions of South America, packs a powerful punch of toxins, containing atropine, hyoscyamine, and scopolamine. As documented in the 2007 documentary VBS.tv "Colombian Devil's Breath," criminals in Colombia have extracted scopolamine from the plant and used as a tonic that makes the victim unaware of what they are doing but entirely conscious. Scopolamine can be absorbed through the skin and mucous membranes, allowing criminals to simply blow the powder in someone's face. The documentary is filled with scopolamine-related horror stories, including an account of a man moving all his possessions out of his apartment (and into the hands of his robbers) without remembering any of it.

9. Nerium oleander

This evergreen shrub is very common is one of the most poisonous plants in the world. "If I were a parent and includes any electrical outlet in the home to protect the children, I really have to ask myself why I had oleander plants grow," said Stewart. Leaves, flowers and fruits contain cardiac glycosides, which have therapeutic applications but is likely to send someone into cardiac arrest should he eat the plants. Stewart showed that there was a woman in California is currently sentenced to death for trying to poison her husband with plants, and two young boys were found dead after ingesting oleander a few years ago. "People tend to get bored, because the flowers are bright and beautiful, a sort of candy-colored but it's a very poisonous plant that will stop your heart .."

10. Cnidoscolus angustidens

Stewart describes crops more painful than poisonous. Mala Mujer, which translates to "bad woman," can be found in the southwest and Mexico and covered with nasty thorns, which can be converted into makeshift barbwire if needed. The real danger, however, comes from the caustic, milk sap that can leak from the plant. The sap, a common feature among many plants in the genus Euphorbia, can cause painful skin irritations and unsightly discoloration. "I've had several people tell me that they had euphorbia saps in their eyes," said Stewart. "And they were quite surprising long-term eye damage."
