Poisonous birds – Not venomous discovered so far
Poisonous birds – No venomous bird has been discovered so far. That is, one whose body would produce a poisonous substance. That would then be transmitted by pecking or wounding with a claw. There are several groups of poisonous birds, that is, poisoning us when we touch or eat them. Their organisms are also probably not producing toxins, but they are able to obtain them from poisonous insects or plants.
Most of them live in New Guinea. Where are several species of Pitohui. Also representatives of the families, store the strong neurotoxin (batrachotoxin) in the skin.
The Gambian Goose from the Anatidae family living in Africa. It accumulates in its tissues another poison, a kantaridine (it gets it from the eaten beetles). Plectropterus gambensis, however, are poisonous only after their consumption. So they gain little thanks to this weapon (except revenge from beyond the grave). On the other hand, other animals of this species benefit from this – a predator who once encountered goose meat will avoid it.
A similar phenomenon applies to the European Common Quail, whose meat is also poisonous, although only for part of the year. Probably quails get their toxin from being eaten plants, and poisoning them are known for a long time and referred to as a coturnism (from the Latin name of the quail Coturnix coturnix).
Ricinus communis – Castor oil plant
Ricinus communis – It probably comes from the north of Africa. It is a 10-meter tall plant that enjoys great popularity in gardening.
- Deadly dose: 15 – 20 seeds
- Death: to 1 week
- Poison: ricin
- Aftermath: renal, liver and spleen failure
- Where it grows: in all tropical and subtropical areas of the world
- Occurrence in Poland: artificially bred
The most dangerous are the bars of its seeds, about 6,000 times more aggressive than cyanide. Causes agglutination of red blood cells and damages the liver, kidneys and spleen. The first symptoms are similar to a cold, followed by headaches, mouth burning, vomiting and internal bleeding. It gradually attacks the entire human circulatory system.
History of the plant:
Castor oil is squeezed from the seeds, from which soap, ointments, drops or perfumes are made. Apparently Cleopatra applied it to her eyes to have a “wider perspective”. In 1978, a Bulgarian secret interview was used to murder the writer and journalist Georgie Markov, who after several days of the fight for his life died of kidney failure in a London hospital.
Abrus precatorius – Originates from tropical Asia
Abrus precatorius – The climbing plant originates from tropical Asia, it is used for the production of rosaries and jewelry.
- Deadly dose: 3 µg of poison
- Death: within 3 – 4 days
- Poison: abrin
- Aftermath: vomiting, bloody diarrhea, hallucinations, renal, liver and spleen paresis
- Where it grows: Asia, Africa and America
- Occurrence in Poland: no
The plant is not poisonous in its entirety, the leaves and roots are edible. The most devious are seeds that contain abrin. A small dose of a substance is enough to kill a person, and the first symptoms will appear after a few hours – problems with breathing, fever, vomiting or severe sweating. Finally, the respiratory system is completely destroyed. Asians are drinking a decoction of the root and leaves as cough and runny nosemedicine.
Conium maculatum – Related to carrots, parsley, caraway
Conium maculatum – Plant related with carrots, parsley and caraway seeds. Its main weapon is the violent poison of the coniine, which causes the man to suffocate with full consciousness.
- Deadly dose: 0,15 g (contained in 20g of the plant)
- Death: within 2 – 3 days
- Poison: coniine
- Aftermath: strangulation through muscle paralysis
- Where it grows: Europe, Africa and Asia
- Occurrence in Poland: yes
Coniine easily penetrates the skin and respiratory system. However, the biggest danger is an easy mistake with the vegetable. At first, the poison has a stimulating effect and then starts blocking the spinal cord’s commands. In this way, muscle paralysis and strangulation occur.
History of the plant:
In ancient Greece and Rome often used during the execution. It enjoyed great popularity among the poisoners (allegedly, Socrates was executed with its help). In Europe, it appeared in the Middle Ages, and gradually disappeared during the 20th century. In the meadows and along roads, it began to grow massively in the 80’s.
Cicuta virosa – It is 150 centimeters high
The highest concentration of toxic substances is found in its rhizome.
- Deadly dose: 2g root
- Death: within 24 hours
- Poison: cicutoxin
- Aftermath: degeneration of skeletal muscles
- Where it grows: North and South America, Europe, Asia
- Occurrence in Poland: yes
In North America it has hundreds of poisoned sheep per year on its conscience. People can mistake its root with the parsley root, and the most common victims of harmful substances are children. Cicutoxin works very quickly, after just a few minutes you can observe irritations of mucous membranes and abdominal pain. If a man survives poisoning, it is very likely that he will struggle with damage to the central nervous system for the rest of his life. Unlike other animals, mice can without fear of poisoning eat plant seeds.
