Angel's Trumpet

paralysis of smooth muscles, confusion, tachycardia, dry mouth, constipation, tremors, migraine headaches, poor coordination, delusions, visual and auditory hallucinations, mydriasis, rapid onset cycloplegia, and death

2

Baneberry

All parts are poisonous, especially the berries, the consumption of which has a sedative effect on cardiac muscle tissue and can cause cardiac arrest.

3

Belladona

The symptoms of belladonna poisoning include dilated pupils, sensitivity to light, blurred vision, tachycardia, loss of balance, staggering, headache, rash, flushing, severely dry mouth and throat, slurred speech, urinary retention, constipation, confusion, hallucinations, delirium, and convulsions

4

All Scleroderma are considered toxic, producing gastrointestinal disorders.

5

Bleeding Heart (Dicentra)

All parts are poisonous if ingested.

6

Celandine (Ficaria verna)

Contact with damaged or crushed Ficaria leaves can cause itching, rashes or blistering on the skin or mucosa. Ingesting the toxin can cause nausea, vomiting, dizziness, spasms, or paralysis.

7

Cocklebur (Xanthium)

 The seedlings and seeds are the most toxic parts of the plants. Symptoms usually occur within a few hours, producing unsteadiness and weakness, depression, nausea and vomiting, twisting of the neck muscles, rapid and weak pulse, difficulty breathing, and eventually death.

8

Columbine (Aquilegia)

 The plant's seeds and roots, are highly poisonous and contain cardiogenic toxins which cause both severe gastroenteritis and heart palpitations if consumed as food.

9

Violet Crowncup (Sarcosphaera)

It gives some individuals gastrointestinal discomfort, including one fatal poisoning in the Jura area in 1920, following which a warning was issued not to eat it raw or in salads. The fruit bodies can bioaccumulate the toxic heavy metal arsenic from the soil.

10

Death Cap (Amanita phalloides)

Amanita phalloides is one of the most poisonous of all known mushrooms. It is estimated that as little as half a mushroom contains enough toxin to kill an adult human. The toxins of the death cap mushrooms primarily target the liver, however other organs such as the kidneys are affected. Symptoms of death cap mushroom toxicity usually occurs six to twelve hours after ingestion.[51] Symptoms of ingestion of the death cap mushroom may include nausea and vomiting, which is then followed by jaundice, seizures, coma which will then lead to death. The mortality rate of ingestion of the death cap mushroom is believed to be around 10-30%.

11

Dumbcane (Dieffenbachia)

Contact with dieffenbachia (typically from chewing) can cause a host of unpleasant symptoms, including intense numbing, oral irritation, excessive drooling, and localized swelling.[14] However, these effects are rarely life-threatening.

12

Foxglove (Digitalis)

digitalis plants have earned several, more sinister, names: dead man's bells and witch's gloves. The entire plant is toxic (including the roots and seeds). The toxins can enter the body through absorption[31] and ingestion and early symptoms of digitalism include nausea, vomiting, diarrhoea, abdominal pain, wild hallucinations, delirium, and severe headache. Other symptoms mentioned are dilated pupils, drooling, weakness, collapse, seizures, and even death.

13

Hemlock (Conium maculatum)

All parts of the plant are toxic, especially the seeds and roots, and especially when ingested. A short time after ingestion, the alkaloids produce potentially fatal neuromuscular dysfunction due to failure of the respiratory muscles. Narcotic-like effects can be observed as soon as 30 minutes after ingestion of green leaf matter of the plant, with victims falling asleep and unconsciousness gradually deepening until death a few hours later.

14

Giant Hogweed (Heracleum Mantegazzianum)

Contact with the plant sap prevents the skin from being able to protect itself from sunlight, which leads to phytophotodermatitis, a serious skin inflammation.[25] A phototoxic reaction can begin as soon as 15 minutes after contact with the sap.

15

Holly

Holly leaves, if eaten, might cause diarrhea, nausea, vomiting, and stomach and intestinal problems.

16

Yew (Taxus baccata)

The entire yew bush, except the aril (the red flesh of the berry covering the seed), is poisonous. Patients who ingest a lethal dose frequently die due to cardiogenic shock, in spite of resuscitation efforts. Dried yew plant material retains its toxicity for several months[37] and even increases its toxicity as the water is removed.

17

Hyacinth (Hyacinthus orientalis)

H. orientalis contains alkaloids and is toxic if eaten in large quantities. The bulb, however, is the most poisonous part and should not be ingested under any circumstances.

18

Destroying Angel (Amanita bisporigera)

The symptoms include vomiting, cramps, delirium, convulsions, and diarrhea.

19

Jessamine

Some people, especially those with respiratory sensitivities or asthma, have reported difficulty breathing, irritation of the nose and throat, headache, nausea, or other symptoms when exposed to the blossom's powerful scent. ingesting plant parts, especially fruit, may result in elevated temperature, rapid pulse, excess salivation and gastritis.

20

Monkshood

Marked symptoms may appear almost immediately, usually not later than one hour, and "with large doses death is almost instantaneous". Death usually occurs within two to six hours in fatal poisoning (20 to 40 ml of tincture may prove fatal).[23] The initial signs are gastrointestinal, including nausea, vomiting, and diarrhea. This is followed by a sensation of burning, tingling, and numbness in the mouth and face, and of burning in the abdomen.[3] In severe poisonings, pronounced motor weakness occurs and cutaneous sensations of tingling and numbness spread to the limbs. The only post mortem signs are those of asphyxia.[3]

21

Larkspur

All parts of these plants are considered toxic to humans, especially the younger parts,[2] causing severe digestive discomfort if ingested, and skin irritation. All plant parts are poisonous in large doses, especially the seeds, that contain up to 1.4% of alkaloids.

22

Mandrake

The alkaloids make the plant, in particular the root and leaves, poisonous, via anticholinergic, hallucinogenic, and hypnotic effects. Anticholinergic properties can lead to asphyxiation. Symptoms may include blurred vision, dilation of the pupils (mydriasis), dryness of the mouth, difficulty in urinating, dizziness, headache, vomiting, blushing and a rapid heart rate (tachycardia)

23

Mangrove (Excoecaria agallocha)

Contact with skin can cause irritation and rapid blistering; contact with eyes will result in temporary blindness. The latex is extremely poisonous. Even dried and powdered leaves contain the poison which can kill fish very quickly.

24

Mistletoe (Viscum album)

Effects include blurred vision, diarrhoea, nausea and vomiting.[18] Less commonly they cause cardiac problems; seizures, hypertension, and even cardiac arrest. Toxins are more concentrated in the leaves and berries of the plant, with teas prepared from the plant being particularly dangerous.

25

Moonflower (Datura)

All parts of Datura plants are toxic, containing dangerous levels of tropane alkaloids and may be fatal if ingested by humans and other animals

26

Nightshade (Hyoscyamus Niger)

Common effects of henbane ingestion include hallucinations,[1] dilated pupils, restlessness, and flushed skin. Less common effects are tachycardia, convulsions, vomiting, hypertension, hyperpyrexia, and ataxia.[1] Initial effects typically last for three to four hours, while aftereffects may last up to three days. The side effects of henbane ingestion are dryness in the mouth, confusion, locomotor and memory disturbances, and farsightedness. Overdosages result in delirium, coma, respiratory paralysis, and death.

27

Oleander (Nerium)

Ingestion of this plant can affect the gastrointestinal system, the heart, and the central nervous system. The gastrointestinal effects can consist of nausea and vomiting, excess salivation, abdominal pain, diarrhea that may contain blood, and especially in horses, colic.[15] Cardiac reactions consist of irregular heart rate, sometimes characterized by a racing heart at first that then slows to below normal further along in the reaction. Extremities may become pale and cold due to poor or irregular circulation. The effect on the central nervous system may show itself in symptoms such as drowsiness, tremors or shaking of the muscles, seizures, collapse, and even coma that can lead to death.

28

Ragwort (Jacobaea vulgaris)

if sufficient quantity is consumed, can be irreversible cirrhosis of the liver of a form identified as megalocytosis where cells are abnormally enlarged. Symptoms include yellow mucous membranes, depression, and lack of coordination.

29

Funeral Bell (Deadly galerina)

exposure to amatoxins may cause irritation of the respiratory tract, headache, dizziness, nausea, shortness of breath, coughing, insomnia, diarrhea, gastrointestinal disturbances, back pain, urinary frequency, liver and kidney damage, or death if ingested or inhaled

30

Snakeweed (Gutierrezia microcephala)

 Toxicity symptoms include death. As little as 9 kilograms (20 lb) of fresh snakeweed consumed by cattle in seven days can cause abortions, and in cattle, sheep, and goats consuming ten to twenty percent of their body weight in two weeks can cause death.

31

Spindle (Euonymus europaeus)

 the fruit is poisonous. Ingestion can result in liver and kidney damage and even death.

32

Common Inkcap

Consuming Coprinopsis atramentaria within a few hours of alcohol results in a "disulfiram syndrome". Symptoms include facial reddening, nausea, vomiting, malaise, agitation, palpitations and tingling in limbs, and arise five to ten minutes after consumption of alcohol.

33

Fools Funnel (Clitocybe rivulosa)

the symptoms are those of muscarine poisoning, namely, greatly increased salivation, perspiration (sweating), and lacrimation (tear production) within 15–30 minutes of ingestion. With large doses, these symptoms may be followed by abdominal pain, severe nausea, diarrhea, blurred vision, and labored breathing.

34

Fly Agaric (Amanita muscaria)

 effects can range from mild nausea and twitching to drowsiness, cholinergic crisis-like effects (low blood pressure, sweating and salivation), auditory and visual distortions, mood changes, euphoria, relaxation, ataxia, and loss of equilibrium (like with tetanus.)

35

Fools parsley (Aethusa cynapium)

Poisoning from fool's parsley results in symptoms of heat in the mouth and throat and a post-mortem examination has shown redness of the lining membrane of the gullet and windpipe and slight congestion of the duodenum and stomach.

36

Wormwood

 can cause convulsions and death when administered in large amounts to animals and humans.

37

False Morels (Gyromitra esculenta)

cause severe gastrointestinal upset, loss of muscular coordination (including cardiac muscle), or even death.

38

Devils Snare (Datura Stramonium)

Datura intoxication typically produces delirium, hallucination, hyperthermia, tachycardia, bizarre behavior, urinary retention, and severe mydriasis with resultant painful photophobia that can last several days.[7] Pronounced amnesia is another commonly reported effect.

39

Lords and Ladies (Arum Maculatum)

irritate the skin, mouth, tongue, and throat, and result in swelling of throat, difficulty breathing, burning pain, and upset stomach.

40

Dog Mercury (Mercurialis perrenis)

Symptoms of poisoning appear within a few hours; they can include vomiting, pain, gastric and kidney inflammation, and sometimes inflammation of the cheeks and jaw ("malar erythema") and drowsiness.[8] Larger doses cause lethargy, jaundice, painful urination, apparently by making the urine acid, and coma before death.

41

Quaker Buttons (Strychnos nux-vomica)

Derived from the seeds inside the tree's round, green to orange fruit.[9] The seeds contain approximately 1.5% strychnine, and the dried blossoms contain 1.0%.[3] However, the tree's bark also contains brucine and other poisonous compounds. This substance throws a human into intense muscle convulsions and usually kills within three hours.

42

Castor Bean (Ricinus)

The toxicity of raw castor beans is due to the presence of ricin. Symptoms of overdosing on ricin, which can include nausea, diarrhea, tachycardia, hypotension and seizures, persist for up to a week. If ricin is ingested, symptoms commonly begin within 2–4 hours, but may be delayed by up to 36 hours. These include a burning sensation in mouth and throat, abdominal pain, purging and bloody diarrhea. Within several days there is severe dehydration, a drop in blood pressure and a decrease in urine. Unless treated, death can be expected to occur within 3–5 days; however, in most cases a full recovery can be made.

43

Golden Chain (Laburnum)

Symptoms of laburnum poisoning may include intense sleepiness, vomiting, convulsive movements, coma, slight frothing at the mouth and unequally dilated pupils. In some cases, diarrhea is very severe, and at times the convulsions are markedly tetanic.

44

Crabs Eye (Abrus Precatorius)

The attractive seeds (usually about the size of a ladybug, glossy red with one black dot) contain abrin, an extremely toxic ribosome-inactivating protein related to ricin. Symptoms of poisoning include nausea, vomiting, convulsions, liver failure, and death, usually after several days. Ingesting a single seed can kill an adult human.

45

Desert-rose/Kudu (Adenium Obesum)

The plant exudes a highly toxic sap which is used by the Meridian High and Hadza in Tanzania to coat arrow-tips for hunting.

46

Horse-chestnum (Aesculus hippocastanum)

All parts of the plant are poisonous, causing nausea, muscle twitches, and sometimes paralysis.

47

Suicide Tree (Cerbera odollam)

The poison blocks the calcium ion channels in heart muscle, causing disruption of the heartbeat. This is typically fatal and can result from ingesting a single seed.

48

Common Ivy (Hedera helix)

The leaves and berries are poisonous, causing stomach pains, labored breathing, and possible coma.

49

Moonseed (Menispermum)

The fruits and seeds are poisonous, causing nausea and vomiting; often fatal.

50

Pennyroyal (Mentha pulegium)

Symptoms that may persist after ingesting a small dose (<10 mL) of pennyroyal oil are nausea, vomiting, abdominal pain and dizziness. Larger volumes may result in multiorgan failure that could lead to death.
