- Everything related to poisonous flora is studied by the science of pharmacognosy. Its roots go back to that distant past, when people explained incomprehensible phenomena by the influence of the gods. The knowledge of the ancestors was passed from mouth to mouth, and thus the legends have come down to our time. In the myths of ancient Greece, poisonous plants were patronized and knew their secrets by Hecate, who was the goddess of the moon, roads and sorceresses. According to legend, the magician king Ayeta in his kingdom erected a temple to her on the Black Sea coast in Colchis. There, in the garden, under the auspices of the goddess Hekate, the sorceress-pharmacides were engaged in the manufacture of various potions from poisonous plants. From the word "pharmakon" (dr. Greek), which means poison, medicine, witchcraft, and such words as pharmacology (the science of medicines), pharmacist (a person who makes drugs) and pharmacognosy (the science of medicinal plants).
- Black henbane (Hyoscyamus niger) - beautiful, but extremely poisonous
- Wolf bast (Daphne mezereum) - a poisonous plant with a speaking name
- In ancient times they knew about poisonous plants, but did not know about toxins. The plant harms human health with toxic chemical compounds - toxins that are contained in poisonous plants. Ask yourself just one question. How many plants do you know that are dangerous to humans? But on Earth there are about 10,000 species, in one only in Russian traditional medicine more than 160 species were used. From such plants, people have long learned to make poisons. Someone sought to use them with malicious intent, and someone in medicinal purposes. It cannot be said unequivocally that poisonous plants are our enemies, since Nature itself has laid down a complex mechanism for the interaction of all life on Earth. And it is not for us to decide that some element should not be on the planet just because it is unsafe for us. Even dangerous plants cannot be destroyed, as this will disrupt the entire chain of the ecosystem. You can learn to beware and appreciate them. Appreciate for the oxygen that they produce, for organic matter which they produce through photosynthesis. And, of course, to cherish the healing properties that their poisons have, used in small doses.
- Poisoning by poisonous plants is possible, but only through personal carelessness or ignorance. Did you know that potatoes contain the poisonous substance solanine? It really is! Only ripe tubers are suitable for consumption, and everything green: a green tuber, tops, inflorescences - contain corned beef, which does not collapse even during heat treatment. Sometimes even cherries, apricots, peaches, bitter almonds are dangerous, because of the pit that children gnaw to eat the kernel. It is in this core that a very dangerous poison is located - hydrocyanic acid. Enough 0.05-0.1 grams to cause instant death. Poisonous substances are produced in different parts of plants, in different periods concentration may vary. For example, a poppy box, like a potato, is only safe when ripe. Hellebore is poisonous only with its young leaves, and plants such as henbane, cockle, gulyavnik are dangerous with ripened seeds.
- Carefully inspect the plant before using it for food. There are poisonous plants that are very similar to ordinary ones. edible plants. For example, poppy seeds and poisonous henbane are very similar to each other, or fruits crow's eye similar to blueberries. Poisonous spotted hemlock resembles parsley leaves and anise fruits.
- Spotted hemlock (Conium maculatum) - disguises itself as parsley or carrot leaves - poisonous!
- Plants that are deadly to humans serve as the natural food of individual animals. For example, the hornbill feeds on poisonous chilibukha seeds, which contain strychnine. Larks and quails peck at hemlock seeds, and forest birds eat poisonous mistletoe berries. There is an aphid that drinks the dangerous hemlock juice. Why is it so? For one creature, a plant is a mortal danger, and for another, an additional opportunity to survive.
- Black crow (Actaea spicata) - also poisonous and dangerous
- May lily of the valley (Convallaria majalis) - poisonous despite all its spring charm, berries are especially dangerous!
- Perennial herb with a parsley scent. The stem is hollow inside, up to 130 cm in height, branched above. Blossoms in July - August, fruits ripen in September. Distributed in Eurasia. Grows in swamps, ditches, river banks, bushes. The plant is highly poisonous, especially the rhizome!
- Medicinal raw material is the herb milestone poisonous.
- Cicutotoxin in non-toxic doses causes sedation, reduces motor activity and blood pressure.
- It is used in homeopathy - for epilepsy, tetanus cramps, migraine, dizziness and malaise caused by worms. In folk medicine, infusion - as a diaphoretic, anticonvulsant, sedative and expectorant; painkiller. Ointment - for arthritis, back pain. Poison milestones should be used only as directed and under the supervision of a physician. Death can occur from respiratory arrest due to acute heart failure. * Veh is toxic to farm animals. The lethal dose for cattle is 200 g of fresh rhizome, for sheep - 60-80 g. The rhizome is easily pulled out of marshy soil when animals bite the above-ground part.
