Plants do not harm you. On the other hand, they don't seem to mind if they do. Even the most harmless shrub will not go out of its way to prevent you from scratching, bleeding, or, in rare cases, dying of respiratory paralysis. And some plants, including the 10 listed here, are well-equipped to make your life miserable if you lose them. You can learn all about this by putting on a Speedo and racing through the thick butterfly. Or you can just read.
1. Poison ivy
You would now think, after so many millennia of scratching, that alien humans would have figured out how to get rid of the poison ivy. No. The problem is that the plant itself is something of a displacement shape: It can be a vine, a climbing vine, or a standing bush. The leaves can be even or slightly etched. They can be hairless or slightly hairy, glossy or dull, with no dentures or teeth. They can be the size of small oysters or, especially when the vine climbs a tree, the size of dinner plates. That being said, leaves always come in groups of three, so this best thing to keep in mind about poison ivy is probably the first thing they've ever told you: Leaves of three, let it be. The active ingredient is uruciol. Take the oil on your skin, and have somewhere between three minutes and an hour to rinse it off before an allergic reaction enters. Some people say you need soap, but I washed the streams immediately after contact and didn't have a reaction. Fun fact: A fourth ounce of uruciol is enough to give every person on earth (population 7.59 billion euros) a rash.
2. Jimson Weed
This annual herb grows up to five feet tall, with a pale-green stem, spreading purple branches, and dark-green leaves. Its large, fancy flowers are creamy white to violet or purple and have a lemon scent. The rest of the plant smells awful and is extremely deep. It also produces a nut-sized nail seed that is difficult to lose. All parts are poisonous and toxicity varies greatly from one plant to another. Jimson weed can kill you. In addition to hallucinations and delirium, it can cause tachycardia (abnormal heart rate acceleration) or hyperthermia (where your body loses its ability to regulate temperature and absorbs heat). The name is a corruption of the "Jamestown weeds", so named because it failed British soldiers who sent an end to the Bacon Uprising in 1676. The men observed hallucinogenic for 11 days, during which they kissed each other " ». easy.
3. Oak Poison
Poisonous oak differs from poisonous ivy in that it always grows upright and has hairy leaflets that are almost always lobed, like the leaf on an oak. I am not sure if I have not seen poisonous oak or if some of the plants I have identified as poison ivy are actually poisonous oaks. It is probably the latter, since the two form a whole series of hybrids. Poisonous oak is said to be more common in the West, and some sources say it may have up to seven leaflets. But it usually has three and almost every other way is like poison ivy: It exists all over the continental US in one form or another and takes you with urushiol. Some people believe they are "immune" to oil, meaning they do not have contact dermatitis. But this so-called immunity can disappear at any time. And often.
4. Giant Hogweed
If you are an outsider, you probably know what a cow ladybug or Queen Anne's lace is. Well, if you see what a mongo version looks like, either, stay away. Also known as cartwheel flower, hogsbane, and (not surprisingly) giant parsnip cow, this noxious weed grows to 16 feet and produces leaves that can have up to four feet. The juice is phototoxic, which means it makes your skin dangerously sensitive to sunlight. The good news is that it takes more than just a touch to influence it. you must crush the plant to produce vigor. The bad news is that the reaction is so much worse than a sunburn that does not seem to be related to the two conditions. A giant rash is more like a severe burn and inflammation that can manifest in just 15 minutes can lead to bad blisters and scarring. Giant hogweed was introduced in the US at the beginning of the 20th century as an ornament made for – you guessed it – it's big. It was later naturalized and found on wet ground in open areas in the Northwest, Upper Midwest, Northeast and Virginia.
5. Nettle Nettle
It is a herbaceous perennial that looks a bit like a mint, except that it is taller, does not taste mushrooms and will sting you from hell. A key recognition feature – and an indication that it will snap you out of hell – is a protrusion of small, spiky hairs on the stem and leaves, which can transmit a cocktail of difficult chemicals. The pain from the bare skin brushing up to the nettle sting (also known as the nettle, weed burning or hazelnut burning) is almost instantaneous and can feel like hitting a bee or multiple bees. The good news is that the sensation generally recedes within a few hours and the rash within 24 hours. The nettle, which grows 3 to 7 feet tall with one to six inch leaves, is actually a healthy and widely consumed vegetable. Boiling the leaves even for a few seconds makes the plant safe. Boiled leaves – add some salt and butter – are incredibly nutritious, though the texture is a bit like a burlap. Nettle is considered to have anti-inflammatory and circulatory benefits and has long been a common ingredient of folk remedies. Roman soldiers sent to Britain made green leaves at their feet, either to promote circulation in the cold or to stay awake while under surveillance. Since the penalty for sleeping in the Roman army was death, ticks may seem like a good alternative.
6. Hemlock water
This is what happened to the Greeks to beat Socrates, or so the story goes. "Coniferous water" is an umbrella term referring to four species of highly poisonous plants that are variously called western aquatic crocus, northern water buzz, reddish stalk and long parsley. All are flowering plants found throughout the US that grow up to 10 feet high and have several white flowers. The most reliable identifying feature is the intact, concave stalk, which is almost always characterized by reddish-purple pimples or streaks. There's no room here for a full tutorial on identification, but be aware that venom horn is often confused with desirable wild plants, such as Queen Anne's lace (wild carrot), swordfish, wild fennel and fresh Flower. All parts of the plant — flowers, leaves, stems, roots, and seeds — are extremely poisonous. Victims usually die of respiratory paralysis within hours of ingestion. Even brushing by the poisonous yolk causes severe skin reactions.
7. Sumac Poison
When most of us think of sumat, we think of the staggram flock – things that grow along the way with the leaves spattered and the fuzzy, red, conical shape of a flower. The sumac is often grown near the beetle, but it's easy to tell from the other. First, the sumac grows almost exclusively in swamps or in very wet soil, and only in the East. If you are chasing mountain ranges, say, in South Dakota, the sumac you are looking for is not poisonous. Second, while the staghorn has a fuzzy stem and tip, the toothy leaves, the nasty things have a fuzzy stem and smooth leaves that are usually more rounded. It also has green-yellow flowers and white or pale yellow berries. Contains our old friend uruzioli, but in a more potent form of poison ivy or oak, watch out. Some herbalists call the sumac demak the most toxic plant to go. Avoid at any time, even when the plant is dead. He's dead like a rattlesnake he's dead.
8. Deadly Nightshade
Also called Belladonna, with fruits known as devil's berries or death cherries, this is one of the most toxic plants in the Western Hemisphere. Physical for Europe, Africa and Asia and naturalized in Washington, Oregon, California, Michigan, New York and New Jersey, the deadly nocturnal is a perennial that grows to six feet, having six legs, of the three and produces dark purple berries. Both the leaves and the fruit play a serious poison. The plant poses a particular risk for children, who are attracted to slightly sweet berries and are known to die from eating only two. Although not as lethal or bitter, the nightshade – which is an invasive vine and much more common – produces red berries in clumps, and will make you very sick on their own.
You have seen this common – and almost ubiquitous – perennial weed that grows up to eight feet along pastures, clearings, fences and roads. White green to reddish purple stems support a canopy of large leaves and grapes that look like berries that start green and turn dark purple. Every part of the plant is, or may be, poisonous, especially the white taproot. Having said that, the sprouts – those that didn't sprout red or purple but almost white, up to eight inches for example – make a delicious vegetable after boiling in at least two water changes until soft. Every home I've ever lived in has flown rising within 100 meters. I fed it to my mother, who likened the taste to wild asparagus. But overall, you don't want to miss it, as it can cause severe gastric distress and worse. Pokeweed killed a fair number of Americans in the 19th century when it was a somewhat common ingredient in tinctures used to treat arthritis.
Foxglove's common names – dead bells, witches and bloody fingers – should be a great tip-off that you don't want to need. Foxglove is a non-indigenous, short-lived perennial that grows to seven feet and places flowers like the bell in its second year. The flowers are usually purple, although the cultivars may be yellow, pink, or white. Beloved by gardeners for its good looks and durability, it has become naturalized throughout the US, especially along roads, rocky outcrops and in gardens, including schools. And every bit of it – seeds, flowers, stalks – can kill you if you swallow it. Foxglove is the source of a powerful steroid used for the production of Digitalis and other heart failure medications. The correct dose can restart a trapped marker if given early. The wrong dose – and the difference with foxglove is razor-thin – it kills you. Eating any part of the plant usually leads to nausea, dizziness, vomiting and diarrhea. In fatal cases, victims experience convulsions and heart failure. The gardens are gorgeous, but don't let anyone kill you.
