http://en.wikipedia.org/wiki/Toxicodendron_radicans Urushiol-induced contact dermatitis is the allergic reaction caused by poison ivy. In extreme cases, a reaction can progress to anaphylaxis. Around 15% to 30% of people have no allergic reaction to urushiol, but most people will have a greater reaction with repeated or more concentrated exposure.

WISTERIA – most parts toxic, seeds can be fatal, flowers are edible
http://www.eattheweeds.com/wisteria-criteria-2/

Wiseria’s multiple personality continues with edibility. The blossoms of the plant are edible raw or cooked. The rest of the plant is toxic per se. In fact, as little as two raw seeds can kill a child. That is not uncommon for a member of the pea family which ranges from edible to toxic. http://1.bp.blogspot.com/-9ia76jzspi4/t3nxbsfez4i/aaaaaaaactq/kostsuuwc1o/s1600/3.22_wisteria_frutescens_1.jpg

POKEWEED – roots and stalk toxic, only young green shoots properly cooked are edible, and maybe the berries. Needs more research.

http://nadiasyard.com/wp-content/uploads/2011/08/dsc_0171.jpg


http://en.wikipedia.org/wiki/Phytolacca_americana



http://www.nlm.nih.gov/medlineplus/ency/article/002874.htm The highest amounts of poison are found in the roots, leaves, and stems. Small amounts are in the fruit. Cooked berries and leaves (cooked twice in separate water) can be eaten (although there is no guarantee that they are safe). The roots should never be eaten.

POISON HEMLOCK- KNOW THIS PLANT! All parts highly toxic.

http://www.thepoisongarden.co.uk/images/conium_maculatum_tweed_220510_18_300.jpg

Closely resembles wild carrot, but stalks are smooth, not fuzzy, with maroon spots. A biennial, it sends up its stalk the second year.


http://en.wikipedia.org/wiki/Conium_maculatum


WATER HEMLOCK KNOW THIS PLANT! All parts highly toxic.

http://en.wikipedia.org/wiki/Cicuta ...Upon consumption, both in humans and other species, the symptoms of poisoning are mainly characterized by generalized seizures. The onset of symptoms following ingestion may be as soon as 15 minutes post ingestion. Initial symptoms reported may include nausea, vomiting, abdominal pain, tremors, confusion, weakness, dizziness, and drowsiness;although the rapid onset of seizure activity may be the first sign presented following poisoning.illustration cicuta virosa0.jpg

GIANT HOGWEED, GIANT COW PARSNIP – highly toxic
http://en.wikipedia.org/wiki/Heracleum_mantegazzianum - The sap of giant hogweed causes phytophotodermatitis in humans, resulting in blisters, long-lasting scars, and—if it comes in contact with eyes—blindness. These serious reactions are due to the furocoumarin derivatives in the leaves, roots, stems, flowers, and seeds of the plant.herkulesstaude fg01.jpg



YELLOW SWEETCLOVER – toxic mold is the issue, edible if not moldy, see link at bottom

http://en.wikipedia.org/wiki/Melilotus_officinalis Sweet clover contains coumarin that converts to dicoumarol (a powerful anticoagulant toxin) when the plant becomes moldy. This can lead to bleeding diseases (internal hemorrhaging) and death in cattle. Consequently, hay containing the plant must be properly dried and cured, especially in wet environments.http://imavex.vo.llnwd.net/o18/clients/urbanfarm/images/farm_seed/yellow_sweet_clover_seed.jpg
Edible in moderation - http://www.eattheweeds.com/melitotus-condiment-to-tea-to-blood-thinner-2/


RHODODENDRONS – most parts, perhaps with the exception of the flowers, related to LAURELS & AZALEAS

http://en.wikipedia.org/wiki/Rhododendron#Toxicology Some species of rhododendron are poisonous to grazing animals because of a toxin called grayanotoxin in their pollen and nectar. People have been known to become ill from eating honey made by bees feeding on rhododendron and azalea flowers…. The rhododendron is the national flower of Nepal, where the flower is considered edible and enjoyed for its sour taste. The pickled flower can last for months and the flower juice is also marketed. The flower, fresh or dried, is added to fish curry in the belief that it will soften the bones. alpenroos.jpg




LAURELS – all parts toxic, related to RHODODENTRONS & AZALEAS

kalmia latifolia


http://en.wikipedia.org/wiki/Kalmia_latifolia#Toxicity Mountain laurel is poisonous to several different animals due to grayanotoxin and arbutin, including horses, goats, cattle, deer, monkeys and humans. The green parts of the plant, flowers, twigs, and pollen are all toxic, including food products made from them, such as toxic honey that may produce neurotoxic and gastrointestinal symptoms in humans eating more than a modest amount.

AZALEAS – all parts toxic, related to LAURELS & RHODODENDRONS

http://www.donaldhyatt.com/images/a-nativeazaleas-01.jpg

http://en.wikipedia.org/wiki/Azalea

In addition to being renowned for its beauty, the Azalea is also highly toxic—it contains andromedotoxins in both its leaves and nectar, including honey from the nectar. The Azalea and Rhododendron were once so infamous for their toxicity that to receive a bouquet of their flowers in a black vase was a well-known death threat.

MISTLETOE – all parts toxic, grows in trees, visible in winter
http://www.hiltonpond.org/images/mistletoeberries01.jpg

http://en.wikipedia.org/wiki/Phoradendron_leucarpum Ingesting the berries can cause "stomach and intestinal irritation with diarrhea, lowered blood pressure, and slow pulse".

YEW BUSH / TREE – most parts toxic, except red sweet flesh that surrounds its highly toxic black seed

taxus baccata mhnt.jpg


http://en.wikipedia.org/wiki/Taxus_baccata Symptoms of yew poisoning include an accelerated heart rate, muscle tremors, convulsions, collapse, difficulty breathing, circulation impairment and eventually heart failure. However, there may be no symptoms, and if poisoning remains undetected death may occur within hours. Fatal poisoning in humans is very rare, usually occurring after consuming yew foliage. The leaves are more toxic than the seed.

OAK TREEleaves and acorns toxic, acorns edible only after proper processing
http://en.wikipedia.org/wiki/Oak The leaves and acorns of the oak tree are poisonous to cattle, horses, sheep, and goats in large amounts due to the toxin tannic acid, and cause kidney damage and gastroenteritisAcorns are also edible to humans in processed form, after leaching of the tannins. quercus robur.jpg


HORSE CHESTNUT TREE – all parts toxic, looks like Chestnut
illustration aesculus hippocastanum0 clean.jpg


http://en.wikipedia.org/wiki/Aesculus_hippocastanum#Medical_uses Raw Horse Chestnut seed, leaf, bark and flower are toxic due to the presence of esculin and should not be ingested. Horse chestnut seed is classified by the FDA as an unsafe herb. The glycoside and saponin constituents are considered toxic.


BLACK LOCUST TREE – bark & leaves toxic, flowers & seeds edible
http://en.wikipedia.org/wiki/Robinia_pseudoacacia Although the bark and leaves are toxic, various reports suggest that the seeds and the young pods of the black locust are edible. Shelled seeds are safe to harvest from summer through fall, and are edible both raw and/or boiledrobina9146.jpg


CHERRY TREES – toxic seeds and foliage, ground seeds contain cyanide, fruit very edible
http://en.wikipedia.org/wiki/Prunus_serotina Like apricots, the seeds of black cherries contain compounds that can be converted into cyanide, such as amygdalin. These compounds release hydrogen cyanide when the seed is ground or minced, which releases enzymes that break down the compounds… the flesh is safe to eat. The foliage, particularly when wilted, contains cyanogenic glycosides, which convert to hydrogen cyanide if eaten by animals. Farmers are recommended to remove any trees that fall in a field containing livestock, because the wilted leaves could poison the animals… Black cherry is a leading cause of livestock illness, and grazing animals' access to it should be limited.http://upload.wikimedia.org/wikipedia/commons/thumb/f/f0/amerikaanse_vogelkers_bessen_prunus_serotina.jpg/220px-amerikaanse_vogelkers_bessen_prunus_serotina.jpg



BUTTERFY WEED – all parts toxic if eaten raw, must be cooked says second source below. More research needed.

http://www.hiltonpond.org/images/butterflyweed03.jpg

http://www.inpaws.org/images/resources/Gordon%20Mitchell%20Articles/GM_butterfly_weed.pdf The Butterfly Weed contains substances that are toxic to both humans and livestock. If consumed by either humans or livestock, toxic symptoms may include bloating, breathing difficulties, dilated pupils, dullness, fevers, seizures, spasms, staggering, stupor, weakness, coma, and even death.


COUNTER POINT: http://www.floralencounters.com/Seeds/seed_detail.jsp?productid=92987 Surprisingly this plant is edible. Both the flower buds and shoots if cooked can be eaten. The shoots like asparagus and the flowers apparently taste like peas although I have yet to try this. However the plant is toxic if eaten raw, always cook or par-boil the plant before eating, never eat anything raw. No part should be eaten in large quantities however as this can cause vomiting. The flower clusters which, produce prolific amounts of nectar, can be boiled down to make a sugary syrup. The nectar production is so prolific in fact that in hot weather it crystallizes out into small lumps which can be eaten like sweets, the nectar is not toxic raw.

DOGBANE – all parts toxic, except perhaps seeds (see below), looks like milkweed, but woody & multi-stemmedhttp://extras.springer.com/2011/978-1-4419-7426-6/color%20herbarium/apocynum%20cannabinum.jpg
http://en.wikipedia.org/wiki/Apocynum_cannabinum All parts of the plant are poisonous and can cause cardiac arrest if ingested.
http://pfaf.org/user/Plant.aspx?LatinName=Apocynum+cannabinum Seeds are edible?
