Here is a list of POISONOUS PLANTS throughout the
UNITED STATES for those open minded people who
do not really believe that all herbs are for human or
even animal consumption, and can comprehend the
fact that many herbs are poisonous.
I'm not going to go into the description of these plants,
you can usually get a good colored picture with
descriptions from other books and online.However,
many books and often online informationdo not even
state if the plant is poisonous or not.So, I'm
going to go through as many plants that I can find and
think of and just give the common names of the plants,
the Latin names, other plants that may be related,
where they are most apt to grow and the dangerous
part of the plant and symptoms of poisoning.
YOU MAY EMAIL ME FOR A PDF FORMAT AND I WILL GLADLY SEND IT TO YOU.

OLEANDER(Nerium Oleander) of the Dogbane FamilyApocynaceae. A/K/Aoleander,
dogbane, laurier rose, rosebay, Anvirzel, Xenavex .Oleander is the official flower of the city of Hiroshima, having been the first to bloom following the atomic bombing of the city in 1945.

Olea.Oleander is one of the most poisonous of commonly grown garden plants
Oleander is a poisonous evergreen shrub or small tree identified by its fragrant white, red, pink, or purple flowers and long slender, leathery leaves, which grow in pairs opposite each other. Oleander is a very beautiful tree.
MOST LIKELY TO BE SEEN GROWING:On the East Coast of the US,it can be planted as far north as Virginia Beach, Virginia, while in California and Texas it is naturalized
as a median strip planting. The white, pink and magenta flowers appear where little else is in bloom.
These tough-as-nails plants thrive along our freeways up and down the southern and hot climate
states. It is commonly used in landscaping freeway medians in California, Texas and other mild-
winter states in the Continental United States because it is upright in habit and easily maintained. Its toxicity renders it deer-resistant. It is tolerant of poor soils and drought
DANGERS:Oleander poisoning occurs when someone sucks nectar from the flowers or chews leaves from the oleander or yellow oleander plant. Poisoning can also happen if you eat honey
made by bees that used the oleander plant for nectar. Oleandersare laced with bitter sap that contains Cardenolide Glycosides, which act upon the heart much like foxglove or Digitalis.
Oleander is very difficult to eradicate once it is large and established.Burning any part of oleander creates toxic smoke.
There have been numerous reports of poisoning and death from ingestion of oleander, oleander leaf tea, and its extracts. It has killed adults, children, pets, and livestock.
Even a small amount of oleander can cause death due to its effects on the heart. Since such tiny amounts can cause death.
Oleander supplements and extracts from any part of the oleander plant should not be used .Even though oleander is poisonous, heavily diluted oleander preparations have been promoted to treat a
variety of conditions including muscle cramps, asthma, menstrual pain, epilepsy, paralysis, skin
diseases, heart problems, and cancer. It has also been used in folk remedies as an insecticide and to kill rats.
The oleander leaf is on the Commission E (Germany's regulatory agency for herbs) list of unapproved herbs. This means that it is not recommended for use because it has not been proven to be safe or effective. The plant parts are toxic, whether cooked, raw, or made into tea.
The oleander plant is poisonous, and many people have died of heart failure or respiratory paralysis after eating parts of the plant or drinking tea made from it.
SYMPTOMS and signs of oleander toxicity are nausea, vomiting, dizziness, drowsiness, high potassium levels, dilated pupils, bloody diarrhea, seizures, loss of consciousness, slow or irregular
pulse, and heart block -- a blockage of the electrical impulses that stimulate the heart to contract.
There have been reports of death occurring after oral and/or rectal administration of the extract from the plant.
