Further you will learn:
- Is the bite of a wasp useful for a person, or is it rather a delusion than the truth;
- What can be harmful is the bite of a wasp, especially for people prone to allergies;
- The composition of the aspen poison and its effects on the human body.
So, how useful is the bite of a wasp and can the poison of this insect on the whole positively influence the human body? Generally speaking, the answer to this question is not as simple as it might seem at first glance. And the "first glance" here is this: because of the similarity of the compositions of aspen and bee venom, many admirers of apitherapy (treating diseases with the help of bee products - including bee venom) tend to believe that the bites of the wasps are useful, and that their poison can be used in fight against various diseases.
According to this version, the obstacle to widespread practical application of aspen poison is only the difficulty of extracting raw materials: if bee venom can be obtained in apiaries in practically unlimited quantities, then to obtain poisonous wasps, it is necessary to look for wild nests and catch the insects themselves. Or somehow organize a massive construction and settling of nests wasps - this technology is not worked out and it seems rather problematic.
But is the wasp bite really useful? Despite the fact that the composition of the poison of this insect has been thoroughly studied, and scientists know how it acts on different tissues and organs, the ultimate benefit and harm of a wasp bite for a man is almost always determined by the individual characteristics of the organism bitten by the response of his immune system.
For example, it is widely known that many people are highly susceptible to insect bites in general, and to hymenoptera bites in particular. Do you think it will be harmful to bite a wasp for them? Practice shows that for such people, even a single bite will not be that harmful, but even it may well be fatal.
An important feature of the aspen poison is its high allergenicity, which sometimes leads to the formation of life-threatening edema and anaphylactic shock in sensitized people.
On a note
Even with the widely known and popular bee venom today, not everything is as unambiguous as it may seem. In the history of apitherapy, not a single scientific experiment has been conducted, the results of which would certainly confirm that bee venom contributes to the cure of certain diseases. It is not known whether he acts healthily on the body, or has a placebo effect.
Its wide popularity and advertising can easily be explained by the rapid development of beekeeping and the attempts by the beekeepers themselves to obtain the maximum income from their occupation. From this point of view, it is easy to explain the unpopularity of aspen poison: it is difficult to extract, and nobody wants to pay attention to its possible medicinal properties, because there is bee venom, which can always be obtained in abundance and used as a panacea against many diseases.
You will not hear much of the high allergenicity of bee venom from folk healers-it's simply not profitable to talk about it again.
The main components of the aspen poison are:
- histamine, which promotes the development of allergic reactions;
- phospholipases - special enzymes that destroy the cellular walls of various tissues, as well as blood cells, resulting in the discharge of a large amount of their contents into the blood (in particular, an additional histamine that multiplies allergy is released from the mast cells);
- hyaluronidase, also destroying the cell membrane and leading to the development of inflammation at the site of the bite;
- Acetylcholine, which plays an important role in the conduct of nerve impulses;
- The hyperglycemic factor, which leads to an increase in the amount of sugar in the blood.
It is worth noting that different wasps have their own specific composition of poison. For example, in the poison of hornets - the largest os - contain special polypeptides mastoparans and krabrolin. These substances also cause destruction of the mast cells of the victim and the release of additional amounts of histamine from them.
On a note
From the bites of hornets in some countries, for example, in Japan, China and the United States, more people die each year than from the bites of poisonous snakes. And in the same Japan hornets cause more deaths, all the wild animals of this country combined.
According to unconfirmed data, regular bites of wasps (like bees) are useful in that they increase the amount of hemoglobin in the blood and lower the level of cholesterol, the expansion of blood vessels.
The effect of small amounts of wasp venom on the human body often leads to some intensification of the victim's breathing, increasing the pulse and increasing the flow of blood to the bitten organ. In more severe cases, there are severe swelling, subcutaneous hemorrhages, pain in the heart, shortness of breath, dizziness, confusion, vomiting - there's no need to talk about any benefit from a bite.
Development of resistance to bites of wasps and bees with aspen poison
A useful area of application of wasps poison is the immunization of people against the bites of Hymenoptera (such people, if they fail to provide competent help on time, could easily perish even from one bite of a wasp or hornet).
To do this, allergy sufferers with increased sensitivity to insect bites are injected into the blood in small doses with a preparation based on purified and processed aspen poison, in which the concentration of allergens is lowered. After such a vaccination, a person temporarily increases the level of antibodies that neutralize toxins in the event of a bite.
"I read somewhere that a man can even die from a bite of a wasp. I can not believe it. As a child, I was often bitten by wasps and bees and nothing more serious than just a bump for a couple of days did not happen. Two years ago I worked as a driver and for a whole summer I drove several apiaries in the fields, and then honey from them to the shops. That's where a lot of bees bitten me, and by the end of the summer I did not notice their bites at all. Well, that is, if it bites - it hurts, but after that I pull out the sting and that's all. A couple of minutes I can not even remember where she bit. And such protection remained. Here recently wasp on the balcony stung - the same result, even the tumor was not. "
It is important to note that the bites themselves can in no case be regarded as a means of strengthening their immunity. For sensitized people, acutely responsive to insect bites, such an independent natural "vaccination" can be deadly. All procedures for allergy sufferers are carried out only in clinics under the supervision of doctors.
Can aspen poison be used as a remedy against cancer?
Really serious to the use of useful properties of aspen poison came in Spain. Most recently, a group of scientists from the Barcelona Institute of Biomedical Research published the results of experiments in which components of aspen poison were used to kill cancer cells.
The idea of such application of aspen poison is well understood: if its components successfully destroy the walls of ordinary cells, as well as blood cells, then they can also destroy cancer cells. The task was only to make toxins selectively affect the cells - to destroy cancer, but not to touch healthy ones.
During experiments in vitro, scientists managed to "glue" the molecules of individual components of aspen poison with a special protein that could only connect to the surface of the cancer cell. As a result, such a tandem passed safely past all healthy cells in the culture and immediately stuck to the cancer cell that came to him on the way. After this, the destruction of the cancer cell shell and its death followed.
All these encouraging results are just the beginning of a long journey. The next step is to test the drug from bee toxin and a special transport protein in mice.
Of course, you can not count pure aspen poison as a useful remedy for cancer. And even more so it would be foolish to use for this purpose the bites of wasps in ordinary life: the poison will equally affect both healthy and diseased tissues.
The Bite of a Wasp
To explain what is bad for a wasp bite is much easier than to find among its useful properties. So, for example, after a bite of a wasp:
- edema and inflammation develop, cells of soft tissues and walls of blood vessels are destroyed;
- the victim suffers painful pain, then usually itching in the place of the bite;
- sometimes the body temperature rises, slight malaise is observed;
- can develop an allergic reaction, the consequences of which will have varying severity in different people - from hives and headaches to severe intoxication, Quincke's edema and even anaphylactic shock.
Bites of wasps are also harmful because they often cause so-called sensitization - an increase in sensitivity to subsequent bites. This means that if the first bite of a wasp passed without serious complications, then the subsequent can cause more and more severe allergic reactions, up to the almost immediate development of Quincke's edema, asphyxia, anaphylactic shock and death.
It is interesting
In the people there is a belief that exactly nine bites of hornets are enough for the death of a person. Each of these bites - despite how much time has passed between them - will have more and more serious consequences. And after the ninth person will die. Therefore hornets are also sometimes called the nine.
Of course, like all the people's signs, this too is rather conventional: many people with frequent bites of wasps, on the contrary, develop immunity, in others, sensitization takes place very slowly, so even more than a dozen bites with long intervals between them will not lead to dangerous consequences. But a large number of allergic people, for whom the wasps bites are extremely dangerous, indicates that, in general, such attacks are quite harmful.
It should also be noted that multiple bites of wasps attacking the swarm can lead to subcutaneous and internal hemorrhages, necrosis, lesions of the internal organs, and sometimes to renunciation of the kidneys - in such situations, even without any inclination to allergies, a person's life can be threatened.
Different wasps - different bites
In total, there are more than 22,000 species of wasps in the world, and each of them has a poison with its own specific properties.
So, the bite of some road wasps is considered the second most painful among the bites of all insects in general (in the first place is the bite of a tropical bullet ant).
And the bites of giant hornets can cause extensive necrosis and internal hemorrhages. This is why, apart from specifying a particular species, it is impossible to say unambiguously how useful or harmful is the bite of a wasp.
It is interesting
Not always the size of the wasp directly correlates with the strength and harm from its poison. Huge wasps-scolias bite hardly stronger than a mosquito, because their poison is not intended to scare away, but to paralyze prey. Conversely, some small German wasps, also called velvet ants, bite much more painfully than ordinary paper wasps.
So, on the whole, it is not possible to say that oas bites are useful, yet. In most cases, these stings cause unpleasant and painful sensations, many people are threatening to go into a far more harmless allergic reaction. And even if you personally feel some benefit from aspen bites, then it is hardly worth recommending such therapy to your friends and acquaintances: who knows how their body will react to the second, third ... or ninth bite ...
