Who made blood recognition and silver needle poison test popular in most of China?

Personally, I think it's the plots in costume dramas that have made blood recognition and silver needle poison testing popular in most of ChinaI believe that many people have watched costume dramas, and the must-have plot in costume dramas is to drop blood to recognize affinity and silver needle to test drugs, I once thought this was true, there is a scientific basis, but now I think about it, it's really uncultured and terrible, it turns out that my ignorance hurt me, and there is actually no scientific basis for dripping blood and silver needle drug test, we all let the TV series deceive.

First of all, let's talk about blood recognition, the plot in the TV series is that as long as two people are related, then their blood will be fused in the water, but in fact, anyone's blood can be fused, even with pig blood,Because blood belongs to red blood cells, and red blood cells only have cell membranes, red blood cells will absorb water in the water, so it leads to the situation of blood fusion, and blood relatives cannot be determined at all.

Next, we are going to talk about the silver needle poison test, the reason why the silver needle will turn black is because of the chemical reaction, the silver needle will turn black as long as it encounters sulfide, and in ancient times, the poison was mainly arsenic, arsenic normally does not contain sulfide, but because the technology of refining arsenic in ancient times was relatively low, there would be some impuritiesAnd these impurities are sulfides, and there is actually a certain basis for the silver needle poison test, and there are also some records about the silver needle poison test in Song Ci's "Collection of Grievances", but I think this can only be regarded as a coincidence.

Now that the society is developing faster and faster, the technology of refining arsenic is getting better and better, and the refined arsenic is also very pure and free of impurities, so the silver needle drug test is also useless for modern timesSo don't blindly believe in the plots in the TV series, we still have to believe in science, and we must talk about the basis for everything.

In ancient times, science and technology were not developed, and medicine was not developed, so it was very popular to test the blood and silver needle to test for poison, and people believed that through these two experiments, they could identify paternity and test poisons.

Dripping blood to recognize affinity and silver needle to test poison both appear in film and television dramas, in order to increase the film and television effect, win the attention of the audience, and increase drama and conflict. From a scientific point of view, both approaches have no scientific basis and are not effective.

It's those costume film screenwriters. Most people know that blood drops and silver needle drug tests are basically seen from TV series, and they are both masterpieces of screenwriters. There is no scientific basis for blood identification, and although the silver needle test is partially credible, it is not entirely correct.

Whether it is a drop of blood to recognize relatives, or a silver needle to test drugs, in fact, they are all common episodes in TV dramas, and their accuracy is very unreliable, so I recommend that you don't believe it too much.

The silver needle test is not reliable, and what really makes the silver needle black, that is, the chemical reaction with silver, is not arsenic trioxide, but the sulfides in the arsenic, which produce silver sulfide (AG2S), a gray-black powder that is insoluble in water. After knowing the basic principle, I probably know that it is basically not scientific to refer to the "silver needle drug test" now.

The poison referred to by the ancients mainly refers to the highly toxic arsenic, that is, arsenic trioxide. In ancient times, the production technology was backward, resulting in arsenic accompanied by a small amount of sulfur and sulfide. The sulfur contained in it can cause a chemical reaction when it comes into contact with silver, causing a black layer of "silver sulfide" to be formed on the surface of the silver needle

Because if you encounter toxins, it will change color.

Silver needles cannot detect poison, but they have a certain disinfecting effect.

Silver and poison will have a chemical reaction and turn black.

Because at this time the silver needle will change color.

Because if there is a toxin, then it will be discolored.

Because the toxin reacts with silver.

I think it's because ancient medical technology wasn't very advanced. So little is known about this area。The most common is the ancient forensic doctor inserting a silver needle into the abdomen of the deceased.

If it turns black, it indicates that the deceased was poisoned, which is also common when detecting whether dishes and teas are poisonous. Even in modern times, some people still base this on the belief that the silver jewelry worn is black, which is a sign of detoxification of the body.

In fact, the blackening of the silver needle does produce a chemical reaction, but the target is the sulfide. Arsenic was probably the most common poison in ancient times, arsenic trioxide. Theoretically, silver needles do not turn black when they come into contact with arsenic.

However, due to the limited production process, arsenic is not of high purity, and it will contain small amounts of sulfur and sulfides, so the silver needles will turn black, which may be why the silver needles are still trying to be poisoned. The "Silver Needle Poison Detection Method" written by Song Ci, a famous forensic scientist in the Song Dynasty, in the year of the "Collection of Records of Clearing Grievances", also has a clear record, but now it seems to be just a coincidence. But in modern times, this method is unreliable.

Arsenic today is extremely pure. There are no sulfide impurities, and the silver needles do not turn black. In addition, common toxic substances such as mercury, cyanide, and nitrite do not react with silver needles and are undetectable

Conversely, some non-toxic substances, such as eggs and kiwifruit, can blacken silver needles and make mistakes due to sulfur or sulfide. As for the blackening of the worn silver, it is caused by sulfide in sweat, hydrogen sulfide and oxygen in the air, and has nothing to do with detoxification of the body.

The most famous paternity test method in ancient times. There were two common methods of paternity testing in ancient times, one was the drip bone method and the other was the blood binding method. The so-called bone drip method is to drip blood onto the bones of the deceased.

If the blood is penetrated, it means that the two are connected by blood. In fact, blood drips onto the bones and seeps in, regardless of whether they are related by blood or not. The blood mixing method is the most common method of blood dropping that we recognize.

If a bowl of water and two drops of blood are combined, they are related. Because red blood cells only have cell membranes, red blood cells can swell and rupture in clear water due to water absorption due to osmotic pressure. On the surface, the blood will spread out and will not be visible to the naked eye, so it feels like two drops of blood are fused.

This is clearly an unreliable method of paternity testing.

Personally, I think it's the plots in costume dramas that have made blood recognition and silver needle poison testing popular in most of ChinaI believe that many people have watched costume dramas, and the must-have plot in costume dramas is to drop blood to recognize affinity and silver needle to test drugs, I once thought this was true, there is a scientific basis, but now I think about it, it's really uncultured and terrible, it turns out that my ignorance hurt me, and there is actually no scientific basis for dripping blood and silver needle drug test, we all let the TV series deceive.

First of all, let's talk about blood recognition, the plot in the TV series is that as long as two people are related, then their blood will be fused in the water, but in fact, anyone's blood can be fused, even with pig blood,Because blood belongs to red blood cells, and red blood cells only have cell membranes, red blood cells will absorb water in the water, so it leads to the situation of blood fusion, and blood relatives cannot be determined at all.

Next, we are going to talk about the silver needle poison test, the reason why the silver needle will turn black is because of the chemical reaction, the silver needle will turn black as long as it encounters sulfide, and in ancient times, the poison was mainly arsenic, arsenic normally does not contain sulfide, but because the technology of refining arsenic in ancient times was relatively low, there would be some impuritiesAnd these impurities are sulfides, and there is actually a certain basis for the silver needle poison test, and there are also some records about the silver needle poison test in Song Ci's "Collection of Grievances", but I think this can only be regarded as a coincidence.

Now that the society is developing faster and faster, the technology of refining arsenic is getting better and better, and the refined arsenic is also very pure and free of impurities, so the silver needle drug test is also useless for modern timesSo don't blindly believe in the plots in the TV series, we still have to believe in science, and we must talk about the basis for everything.

I think it's some of the plots in those costume dramas that have made blood recognition and silver needle poison testing popular in most of China.

Because people's technology was still limited at the beginning, these were the only solutions.

I don't think the ancient medical technology was very advanced. So I don't know much about this knowledge.

This should be because these two methods are more convincing, so this is why they are like this.

Due to the relative backwardness of science and technology in ancient times, the medical methods are relatively simple, and because of this, the ancient blood and silver needle poison test plays a certain role in a certain aspectHowever, fundamentally speaking, it is not completely reliable, which is also due to the lack of major scientific and technological innovations due to technical limitations at that time, and in general, it is also due to the following reasons.

3. The ancient blood recognition affinity and silver needle master and apprentice were influenced by the scientific environment at that time, so they were not completely reliable. In fact, for us, the ancient blood recognition affinity and silver needle poison test were caused by the cognitive limitations of the time, and there was a certain rationality at that time, on the one hand, there were indeed relatively accidental events, but fundamentally speaking, these methods are not able to fundamentally prove these relationships, and in general, these methods are not very reliable.

In fact, for us, the purpose of the ancient blood recognition is not to completely test the parent-child relationship, it may be mixed with more human feelings, and the purpose is also to strengthen the imperial rule and promote the national prestige.

Reliable. Blood of the same blood type will melt if it drops together, and the silver needle test is a chemical reaction and is real.

Unreliable. Because most of the blood is water, it is normal for water to be compatible with each other. The reason why the silver needle turns black when it encounters poison is because some elements of the poison have a chemical reaction with the silver needle, but many of today's poisons are free of impurity elements and are difficult to test.

Unreliable. There is a lack of scientific basis for blood recognition and silver needle drug testing, and some of them are made up blindly in TV dramas, so we still believe in science and use scientific means to detect it.

Unreliable, because humans have blood type O, and blood type O is dissolved in any other blood type. At the same time, some toxic ingredients do not react with silver, so the test is not 100% accurate.

Personally, I think it's unreliable, because there is no scientific basis for this way, so we just treat it as a legend, or a film and television drama entertainment.

It is unreliable to recognize relatives by dripping blood, and now we have to confirm DNA through such complex technical means, if it is really that simple, why bother so much, the silver needle test poison is only for arsenic, it will have an effect, and other poisons can not be detected.

It is unreliable, because these practices have no scientific basis and do not represent the facts, so we must believe in science.
