Silver ornaments are welcomed by most people, not only because silver is a precious metal, but also because it has bactericidal effect from a health point of view. In fact, the principle of silver sterilization is not an unreasonable reason spread by many people, because it can absorb toxins from the body. The antibacterial mechanism of silver is metal ion and photocatalysis. Mr. Zhang Wenzheng once said that the chemical structure of silver determines that silver has high catalytic ability, and the reduction potential of highly oxidized silver is extremely high enough to generate atomic oxygen in the surrounding space.

Atomic oxygen is highly oxidizing and can kill bacteria. Ag+ can strongly attract sulfhydryl group (-SH) on protease in bacteria, and quickly combine with it, making protease inactive and leading to bacterial death. When the bacteria are killed by Ag+, Ag+ is released from the bacterial carcasses and then comes into contact with other colonies. The above process is repeated, which is also the reason for the persistence of silver sterilization. According to scientific research, typhoid bacilli can only survive 1 hour on silver tablets, and diphtheria bacilli can only survive for 3 hours on silver tablets. The bactericidal effect of silver can be seen! Therefore, the ancients liked to use silverware to hold food, first, because it can show the identity of the owner, and second, because the food held in silverware is not perishable and can be kept fresh. Therefore, some people with low immunity prefer to choose silver ornaments to kill bacteria that may cause disease.

It is easy for me to say that the "silver needle test" that we often see in martial arts novels is actually because silver will react with toxic substances to generate colored oxidized substances, so we can use pure silver needles to test whether food is toxic; As for the human body, it will be abnormal without wearing silver ornaments, which fully shows that people are a whole. When there is a problem in a certain part of the body, it will lead to corresponding changes in body fluids, sweat and skin. Silver worn beside the body will naturally react with substances in body fluids. So I want to tell the villagers that from a certain point of view, silver ornaments can remind us of some abnormal information about our bodies, but experts believe that silver can't treat human diseases, so villagers should never treat silver ornaments too magically.

Speaking of jade, the jade culture in China can be traced back to the Paleolithic Age and has been passed down for thousands of years. There are many legends about jade. There are many legends that jade can exorcise ghosts, ward off evil spirits and protect people's safety and good luck. But now, as a scientific and technological society, if I still believe the stories handed down by these ancestors, I will really feel great pressure. According to incomplete research, the health care function of jade has indeed been recognized by modern science. Most people think that jade is a natural mineral, which contains a lot of trace elements such as gold, silver, silicon, zinc, iron, selenium, magnesium and manganese, and some jade also contains trace radioactive elements. Jade is worn close to the skin and directly attached to the skin. Trace elements in jade will directly affect the human body. At the same time, the electromagnetic effect produced by friction will also resonate with the human body, thus achieving the purpose of regulating human function and promoting health. In addition, trace elements in jade may also have a calming effect on human body. Therefore, in ancient times, rich families used jade pillows, and only by sleeping well can they live well. Using jade pillows to help sleep is also one of the means of health care. However, it has been mentioned that wearing jade ornaments should be close to the body, and playing with them often, because the trace elements in jade ornaments can better produce health care effects through contact and friction with the skin.

Many people will buy silver safety locks for newborn babies. I also heard the old man say, don't wear jade if you are in poor health, or jade will suck the essence of people. In fact, there are no special taboos and precautions for wearing silver and jade, because silver is a precious metal with stable properties and jade is also a natural ore, which will not cause harm to human health.
