Here is a list of wild plants in Germany that are poisonous.
Some of the plants growing here can be fatal if eaten, like the Belladonna, so if you have small children keep a close eye out for them and make sure to let your kids know never to eat wild berries unless an adult is with them and knows the berries are safe to eat (wild blackberries or strawberries).
Check this Wiki for more information on the plants or feel free to google them.
|Aconite||The poison is concentrated in the unripe seed pods and roots, but all parts are poisonous. Causes digestive upset, nervous excitement. The juice in plant parts is often fatal|
|The bulbs are poisonous and cause nausea, vomiting, diarrhea. Can be fatal.|
|Belladonna / Nightshade||Belladonna is one of the most toxic plants found in the Western hemisphere. All parts of the plant contain tropane alkaloids.The berries pose the greatest danger to children because they look attractive and have a somewhat sweet taste. The consumption of two to five berries by children and ten to twenty berries by adults can be lethal. The root of the plant is generally the most toxic part, though this can vary from one specimen to another. Ingestion of a single leaf of the plant can be fatal to an adult|
|Black hellebore||"Black hellebore" is also toxic, causing tinnitus, vertigo, stupor, thirst, a feeling of suffocation, swelling of the tongue and throat, emesis and catharsis, bradycardia (slowing of the pulse), and finally collapse and death from cardiac arrest. Helleborus niger (black hellebore or Christmas rose) contains protoanemonin, or ranunculin, which has an acrid taste and can cause burning of the eyes, mouth and throat, oral ulceration, gastroenteritis and hematemesis.|
|Common Yew||Most parts of the tree are toxic, except the bright red aril surrounding the seed, enabling ingestion and dispersal by birds. The major toxin is the alkaloid taxane. The foliage remains toxic even when wilted or dried. Symptoms include staggering gait, muscle tremors, convulsions, collapse, difficulty breathing, coldness and eventually heart failure. The wood remains poisonous after it is cut. Fatal poisoning in humans is very rare.|
|Daphne||The berries (either red or yellow) are poisonous, causing burns to mouth and digestive tract, followed by coma. Often fatal.|
|Dog parsley||Most commonly only nausea and vomiting seen. Severe signs could include convulsions, respiratory arrest, and death, but concentration is usually too low to cause these signs|
|Foxglove||The leaves, seeds, and flowers are poisonous, containing cardiac or other steroid glycosides. These cause irregular heartbeat, general digestive upset, and confusion. Can be fatal.|
|Henbane||Henbane can be toxic, even fatal, to animals in low doses. Its name dates at least to 1265. The origins of the word are unclear but "hen" probably originally meant death rather than referring to chickens. Hyoscyamine, scopolamine, and other tropane alkaloids have been found in the foliage and seeds of the plant. Common effects of henbane ingestion in humans include hallucinations, dilated pupils, restlessness, and flushed skin. Less common symptoms such as tachycardia, convulsions, vomiting, hypertension, hyperpyrexia and ataxia have all been noted.|
|Herb Paris||It occurs locally in temperate and cool areas throughout Europe and Asia . In Britain it is more frequently found in the east of the country but it is uncommon throughout its range. Each plant only produces one, blueberry-like fruit, which is poisonous.|
|Laburnum||All parts, especially the seeds, are poisonous, causing excitement, staggering, convulsions, coma; occasionally fatal.|
|Larkspur||Young plants and seeds are poisonous, causing nausea, muscle twitches, paralysis. Often fatal.|
Conium contains the piperidine alkaloids coniine, N-methylconiine, conhydrine, pseudoconhydrine and γ-coniceine (or g-coniceïne), which is the precursor of the other hemlock alkaloids.The most important and toxic of these is coniine, which has a chemical structure similar to nicotine. Coniine is a neurotoxin, which disrupts the workings of the central nervous system and is toxic to humans. Ingestion in any quantity can result in respiratory collapse and death. Coniine causes death by blocking the neuromuscular junction in a manner similar to curare; this results in an ascending muscular paralysis with eventual paralysis of the respiratory muscles which results in death due to lack of oxygen to the heart and brain. Death can be prevented by artificial ventilation until the effects have worn off 48–72 hours later.For an adult the ingestion of more than 100 mg of coniine (approximately 6 to 8 fresh leaves, or a smaller dose of the seeds or root) may be fatal.
|Stinging Nettle||The leaves and stems are very hairy with non-stinging hairs and also bear many stinging hairs (trichomes), whose tips come off when touched, transforming the hair into a needle that will inject several chemicals: acetylcholine, histamine, 5-HT or serotonin, and possibly formic acid. This mixture of chemical compounds cause a painful sting or paresthesia from which the species derives its common name, as well as the colloquial names burn nettle, burn weed, burn hazel. The pain and itching from a nettle sting can last from only a few minutes to as long as a week.|
|Stinking Hellebore||All parts of the plant are poisonous, containing glycosides. Symptoms of intoxication include violent vomiting and delirium.|
|Thorn Apple / Datura||All Datura plants contain tropane alkaloids such as scopolamine, hyoscyamine, and atropine, primarily in their seeds and flowers. Because of the presence of these substances, Datura has been used for centuries in some cultures as a poison and hallucinogen. There can be a 5:1 toxin variation across plants, and a given plant’s toxicity depends on its age, where it is growing, and the local weather conditions. Many tragic incidents result from modern recreational users ingesting Datura. Children are especially vulnerable to atropine poisoning, and their prognosis is likely to be fatal. In some parts of Europe and India, Datura has been a popular poison for suicide and murder.|
|The root, when freshly pulled out of the ground, is extremely poisonous and contains the toxin Cicutoxin. When dried, poison is reduced to roughly 3 to 5 percent of that when fresh.|
|Wisteria||All parts of the plant contain a glycoside called wisterin which is toxic if ingested and may cause nausea, vomiting, stomach pains, and diarrhea. Wisterias have caused poisoning in children of many countries, producing mild to severe gastroenteritis.|
Germany also has a fast array of Mushrooms growing in the forests and countryside. Many Germans spend hours in the fall collecting those to prepare soups or sauces with them. However unless your an experienced mushroom picker I would discourage you from doing so, since we have a few very toxic mushrooms.
|Green Amanita||These toxic mushrooms resemble several edible species (most notably the caesar’s mushroom and the straw mushroom) commonly consumed by humans, increasing the risk of accidental poisoning. A. phalloides is one of the most poisonous of all known toadstools. It has been involved in the majority of human deaths from mushroom poisoning. It has been the subject of much research, and many of its biologically active agents have been isolated. The principal toxic constituent is α-amanitin, which damages the liver and kidneys, often fatally.|
|White Amanita||Although the edibility has not been documented for this species, some sources have noted that toxicity is suspected, see above.|
|Fool’s Webcap||Both of these mushrooms can be confused with each other and many incidents of mushroom poisoning have occurred where inexperienced mushroom hunters have confused these mushrooms with edible mushrooms, such as the chanterelle, or hallucinogenic mushrooms.One should be especially cautious when picking mushrooms like the cleaned funnel chanterelles as these mushrooms share the same habitat as the deadly webcap and the fool’s webcap. In many incidents where this mushroom has been ingested, death has occurred.|
|Deadly Webcap||The Deadly webcap and the Fool’s webcap both contain the toxin orellanin and orellin , orellinin and Cortinarin A,B,C . A characteristic of orellanin poisoning is the long latency; the first symptoms usually don’t appear until 2–3 days after ingestion and can in some cases take as long as 3 weeks. The first symptoms of orellanin poisoning are similar to the common flu (nausea, vomiting, stomach pains, headaches, etc.). These symptoms are followed by early stages of renal failure (immense thirst, frequent urination, pain on and around the kidneys), and eventually decreased or nonexistent urine output and other symptoms of renal failure occur. If left untreated death will follow. There is no known antidote against orellanin poisoning, but early hospitalization and treatment can sometimes prevent serious injuries and usually prevent death. If you suspect orellanin poisoning, acting on it quickly can save your life.|
|Autumn Skullcap||Ingestion in toxic amounts causes severe liver damage with vomiting, diarrhea, hypothermia, and eventual death if not treated rapidly. About ten poisonings have been attributed to the species now grouped as G. marginata over the last century|
|Toadstool / Fly Amanita||Although generally considered poisonous, deaths are extremely rare.|
|Brown Roll-rim||The symptoms from poisoning are rapid in onset; consisting initially of vomiting, diarrhea, abdominal pain, and associated hypovolemia.Shortly after these initial symptoms appear hemolysis develops signified by oliguria, anuria, hemoglobin in the urine (hemoglobinuria) and anemia. Medical laboratory tests consist of increasing bilirubin and free hemoglobin, and falling haptoglobins. Hemolysis may lead to numerous complications including acute renal failure, shock, acute respiratory failure, and disseminated intravascular coagulation. These complications can cause significant morbidity with fatalities having been reported.|
|Panther Cap||Another member of the Death Cap family, this is also very poisonous, although not normally fatally so.|
|Devil’s Bolete||It is generally regarded as a poisonous mushroom, with predominantly gastrointestinal symptoms of nausea and vomiting occurring if eaten raw. However, reports of poisoning are rare due to its odd appearance and at times putrid smell minimizing casual experimentation.|
|Deadly Fibrecap||Inocybe erubescens contains muscarine, in much higher doses than Amanita muscaria and has been known to cause death, unlike the latter mushroom. One fatality was recorded in Surrey in southern England in 1937|
|Sulphur Tuft||The Sulphur Tuft is bitter and poisonous; consuming it can cause vomiting, diarrhea and convulsions. The principal toxic constituents have been named fasciculol E and fasciculol F.|
As its name implies, the Sickener is inedible, though not as dangerous as once described in older mushroom guides. The symptoms are mainly gastrointestinal in nature: diarrhoea, vomiting and colicky abdominal cramps. The active agent has not been identified but thought to be sesquiterpenes, which have been isolated from the related genus Lactarius and from Russula sardonia.
|Yellow-staining Mushroom||A mushroom of the genus Agaricus, which displays a strong yellow coloration at the base of the stem when cut. It is poisonous for most people, causing gastrointestinal upsets but is eaten by some without apparent negative effect.|
|Common Earthball||Ingestion of scleroderma citrinum can cause gastrointestinal distress in humans and animals, and some individuals may experience lacrimation, rhinitis and rhinorrhea, and conjunctivitis from exposure to its spores.|
|Livid Entoloma||It may be mistaken for the edible St Georges’ mushroom (Calocybe gambosa), or miller (Clitopilus prunulus) and has been responsible for many cases of mushroom poisoning in Europe. E. sinuatum causes primarily gastrointestinal problems that, though not generally life-threatening, have been described as highly unpleasant. It is generally not considered to be lethal, although one source has reported deaths from the consumption of this mushroom.|
|Entoloma nidorosum||Toxic Mushroom that has a strong Ammonia odor.|
|Gassy Webcap||The mushroom has been variously reported as "mildly poisonous",or indigestible.|
