Nerium oleander is an unquestionably beautiful plant, famous for its delicate white or pink flowers. You'd probably be shocked to discover that this pretty plant actually has one of the most poisonous flowers in the world. If ingested, it can cause vomiting, diarrhea, seizures, coma or even death.
Monkshood is a general term used to refer to plants within the genus Aconitum. Other common names of this plant include aconite, devil's helmet, queen of poisons, and wolfsbane. It's a wildflower mainly found in the northern hemisphere in the forests and creek banks of mountainous areas.
The acute toxicity of arsenic has been recognized since antiquity. Known as both the “king of poisons” and the “poison of kings,” the element's infamy grew during the Middle Ages as an almost untraceable means of murder.
1. Botulinum toxin. Scientists differ about the relative toxicities of substances, but they seem to agree that botulinum toxin, produced by anaerobic bacteria, is the most toxic substance known.
Gympie-Gympie is a relatively harmless looking plant... until you touch it. The plant has a sting that feels like being burnt with hot acid and electrocuted at the same time, and often drives people in agony to kill themselves and is thus also called the "suicide plant".
Deadly Nightshade
The flowers of this plant are small, reddish purple and tubular shaped, but it is the berries that are the most deadly part of the plant. The atropine found in belladonna disrupts the nervous system and can destroy the body's ability to regulate breathing and heart rate, leading to death.
Toxicity. D. moroides is notorious for its extremely painful sting which may leave victims suffering for weeks or even months. It is reputed to be the most venomous plant in Australia, if not the world.
Deadly Nightshade (Atropa belladonna)
Nightshade contains atropine and scopolamine in its stems, leaves, berries, and roots, and causes paralysis in the involuntary muscles of the body, including the heart. Even physical contact with the leaves may cause skin irritation.
Gympie Gympie

Glyphosate is a non-selective herbicide, meaning it will kill most plants. It prevents the plants from making certain proteins that are needed for plant growth. Glyphosate stops a specific enzyme pathway, the shikimic acid pathway. The shikimic acid pathway is necessary for plants and some microorganisms.
Accidental poisoning can occur by ingestion (as little as one leaf of the nerium oleander may be lethal in children), by inhalation of smoke from burning oleander, or from the use of medical preparations from the leaves of oleander which have been used as treatments for malaria, leprosy, venereal diseases, and to ...
Glyphosate kills plants by interfering with the synthesis of proteins produced only by plants. Glyphosate is also effective against a wide range of woody plant species. Glyphosate-containing products used by commercial applicators contain 30.8%–39.9% glyphosate (acid) and are available in 1 gal.
The manchineel (aka Hippomane mancinella, aka the Tree of Death) is native to coastal areas in southern North America, such as South Florida, as well as the northern reaches of Central and South America and the Caribbean.
Belladonna. Its name might mean “beautiful woman” in Italian, but this decorative shrub—also known as deadly nightshade—is quite the femme fatale.

Sarin (inhaled)

Mithridatism is the practice of protecting oneself against a poison by gradually self-administering non-lethal amounts. The word is derived from Mithridates VI, the King of Pontus, who so feared being poisoned that he regularly ingested small doses, aiming to develop immunity.
He cultivated an immunity to poisons by regularly ingesting sub-lethal doses; this practice, now called mithridatism, is named after him. After his death, he became known as Mithridates the Great.
