MEDICINAL AND POISONOUS PLANTS

Since ancient times, people have noticed medicinal properties in some plants. True, it was not known what they were connected with, and they explained them by magic (that is why connoisseurs of medicinal herbs were burned at the stake in the Middle Ages as witches and sorcerers). To collect herbs, they waited for a special arrangement of the stars, fasted, bathed in the dew before, and recited spells.

The man also knew that some plants are poisonous. From time immemorial, the natives of South America have smeared their arrows and spears with curare (arrow poison). It was obtained from plants of the Loganiaceae family containing strychnine. The most famous representative of this family is chilibuha (vomit), which grows in tropical Asia. Once in the bloodstream, strychnine causes spinal cord paralysis and death. The Europeans called the curare "soundless death." One poisoned arrow could kill a jaguar. Curare is now used to deprive experimental animals of the ability to move.

But the most surprising thing was that the same plants could be both medicinal and poisonous, depending on the method of application and dose. For example, foxgloves, known for their bright (yellow, purple) thimble-shaped flowers, are poisonous, but they make good heart remedies.

Similar medicines are obtained from oleander (by the way, it is also a houseplant). Meanwhile, the juice of this plant is very poisonous. Once upon a time in Italy, several French soldiers roasted meat on oleander skewers. Of the 12 participants in this dinner, 8 died of poisoning. By the way, the wasp-eater is a bird of prey, decorating its nest with green oleander branches, thus cleansing it of microbes and insects.

What about plants like the South American coca bush? The alkaloid (cocaine) obtained from it is an analgesic agent, but, in addition, it is also a dangerous drug.

One would like to agree with the opinion of Paracelsus: "One dose alone makes a substance poison and medicine."

VALERIAN

Healing or poisonous substances of plants can act in completely different ways on different animals. This is perfectly illustrated by the example of Valerian officinalis. For humans, valerian tincture is known to be a sedative. And for cats - exciting. It is no coincidence that valerian is called cat root and meow! Those who have read The Adventures of Tom Sawyer by Mark Twain probably remember the episode when Tom treated Peter to the cat with valerian drops: “Peter jumped two meters up, let out a wild cry and darted around the room, hitting furniture, overturning flower pots and making an unimaginable noise ... Then he danced in the middle of the room in frenzied gaiety, bowing his head to his shoulder and howling expressing indomitable joy. Then he rushed around the house, sowing chaos and destruction on his way. "

ANCHAR

We know Anchar thanks to the poem by Alexander Pushkin:

In the stunted and stingy desert,

On the soil, red-hot heat,

Anchar, like a formidable sentry,

Stands - alone in the entire universe.

The nature of the thirsty steppes

She gave birth to him on the day of anger,

And dead green branches

And gave poison to the roots.

Poison drips through its bark

Melt out from the heat by noon,

And freezes in the evening

Thick transparent resin.

A bird does not fly to him,

And there is no tiger: only a black whirlwind

Will run up to the tree of death -

And rushes away, already pernicious.

An impressive picture, isn't it? But from the point of view of botany, this description of anchar poisonous is not entirely accurate. It grows in South Asia and, together with mulberries and figs, belongs to the mulberry family. Its milky juice is really poisonous, and the inhabitants of Java even poisoned their arrows with it. But even this milky juice is not fatal. And all other parts of the plant are simply harmless. And of course, birds can sit quietly on its branches without fear of being poisoned.

WHAT IS THE HEALING POWER OF THE PLANT?

The "father of medicine" Hippocrates believed that the healing power of a medicinal plant lies in the unique mixture of its living juices. Galen, on the contrary, began to boil or insist plants with water or wine, receiving "galenic preparations" and highlighting the "healing principle".

Paracelsus believed that the "healing principle" is a special chemical, and the doctor must purify it. But such substances were discovered only at the beginning of the 19th century, when substances with alkaline properties were first discovered in plants - alkaloids (which means "similar to alkalis"): caffeine and strychnine (1819), quinine (1821), etc. All of them had a strong effect on the human body (although alkaloids are not the only such substances in plants). The discovery of alkaloids in terms of its importance for botany was compared with the discovery of iron by man.

TERIAC

In ancient times, theriak was considered an antidote for any poisoning, as well as a panacea for all diseases. There is a legend that in the 1st century. BC NS. the king of Ponta Mithridates, fearing poisoning, used teriak every day. When Mithridates was defeated by the Romans, he could not commit suicide with the help of poison, since no poison acted on him, and was forced to stab himself. The basis of theriak was snake meat, and the total number of its constituent parts reached a hundred. All these parts were ground into porridge and mixed with honey. This was done at times solemnly, in front of a large gathering of the public. But by the beginning of the XX century. Teriak was gradually forgotten and became part of history.

In small doses, toxic substances have a therapeutic effect, and species containing these substances are also medicinal plants. Therefore, the use of medicinal plants requires caution and the obligatory recommendation of specialists.

Many species of plants belonging to the medicinal group are very rare. Harvesting of such plants is impossible and unacceptable. These types include - thyme (thyme), lily of the valley, nut-bearing lotus, marsh calamus.

In folk medicine, lichen is very often used - wandering parmelia (cut grass, crow's feet - the popular name). Harvesting of this plant is possible everywhere. Parmelia develops on loamy and clayey slopes of the Baer hillocks, hills throughout the region. The collection takes place in May.

Mass harvesting of medicinal plants in the region is not carried out, but there is such a possibility.

3. Precautions when using poisonous medicinal plants

Among even well-known medicinal plants, there are many poisonous, but they are successfully used for medicinal purposes. Therefore, one cannot self-medicate without accurately determining the diagnosis of the disease by the attending physician and without his recommendation or advice on the possibility of using folk remedies at home.

When collecting poisonous medicinal plants, precautions should be taken: do not taste, wash your hands after working with them, protect your eyes from dust with glasses.

It must be remembered that any herb, for some the most useful and harmless, for others can be a powerful allergen. Hay fever is a very serious condition caused only by the smell of herbs, but not the worst when, under the influence of an allergic reaction, swelling of the respiratory tract occurs too quickly. Therefore, even the herb allowed for your treatment needs to be checked: is it compatible with the body of the person who uses it. Phytotherapists always warn patients that the first dose should be used at the lowest dose. And if a person feels worse, if a rash appears on his face and hands, in no case should one more try to be treated with this particular herb. In the arsenal of both scientific and traditional medicine, there are enough other herbs of life, very similar in chemical composition, for the treatment of the same diseases.

You cannot be treated endlessly with the same herb. You need to ask your doctor how many days you can drink this medicine, after how many days phytotherapy should be resumed. Firstly, "addiction" occurs in the body; secondly, the body can be oversaturated with chemicals that were contained in the grass and helped a person to cope with the disease. But in large quantities, these same substances can cause irreparable harm to the body. Practitioners noted cases when the uncontrolled and prolonged use of such wonderful plants as, for example, St. John's wort, tansy, wormwood, lilac, immortelle, flax, pink clover, brought harm to the patient instead of relief.

To pick herbs, be sure to take scissors and a knife with you.

When collecting plants, you should try not to pick poisonous herbs with your bare hands; it is impossible for their juice or dust from them to get into the eyes and nose of the collector. After collecting the poisonous herb, dry it in a place that is out of the reach of children and pets.

Store raw materials containing toxic and potent substances in lockers or closets.

It is necessary not to forget to be sure to write a label on the jars and boxes with grass, indicating the name of the herb and the time of collection.

So, to collect poisonous medicinal herbs, you must definitely take scissors and a knife with you. By this, a person will not only significantly speed up the collection and facilitate labor, but also save the life of the plant, and this will also prevent it from possible poisoning with poisonous medicinal plants.

You cannot put different herbs in one bag, they should be dried separately. A mistake can harm a person.

Conclusion

Thus, using medicinal herbs for treatment, it is necessary:

· Exactly observe the dosage indicated in the prescription when mixing medicinal raw materials;

· To prepare a dosage form (infusion, broth, tincture, etc.) exactly keeping the technology of its preparation;

· Follow the rules for storing the prepared form;

· Strictly observe the dosage when taking the finished medicine;

· Carefully study the contraindications of all components included in the collection and relate them to the present diagnosis, as well as the patient's previous illnesses.

Only this approach will ensure the optimal effect and safety of treatment with medicinal herbs.
