According to Compendium of Materia Medica, silver has the effects of "calming the five internal organs, calming the mind, treating fright, strengthening bones and muscles, calming the heart and improving eyesight". Some people say that pure silver can ward off evil spirits. Therefore, in many folk places, the custom of wearing silver lock bags and bracelets for children is circulated, which is conducive to discharging "fetal poison" to children, and can also play a role in calming the nerves, ward off evil spirits and soothe the nerves.
At present, people like to wear silver ornaments more and more. Silver ornaments are not only beautiful and generous, but also economical and practical. Most importantly, they are also good for human health. Compared with precious metals such as gold, it is more effective for human health.
Pure silver products that release silver ions can generate magnetic fields in a certain range and release silver ions according to the environment. This kind of silver ion can stimulate energy, so wearing silver jewelry also has health care effect on human body. Silver-plated jewelry and jewelry with insufficient silver purity will not have this effect.
People living in humid areas are prone to rheumatism, and close-fitting silver ornaments can absorb the hot and humid air in the human body, so wearing silver ornaments for a long time can prevent or alleviate rheumatism. Acupuncture in traditional Chinese medicine uses silver needles, because it is difficult for bacteria to reproduce on silver needles. Silver is known as "bionic metal", which is non-irritating to human body and incomparable to any other metal.
Lead and silver ornaments adsorbed on human body surface can adsorb lead attached to human body surface. Silver cups and tableware will absorb lead in water and food. Long-term use of silver tableware can reduce the intake of lead and prevent chronic lead poisoning.

The bactericidal ability of silver ions is particularly strong. As long as every liter of water contains two milligrams of silver ions, most bacteria in the water can be killed.
Silver can inhibit the existence of almost all bacteria and extracellular viruses known at present, and will never produce any drug resistance. As early as a few years ago, there were various silver ion fungicides on the domestic and foreign markets, which not only had obvious bactericidal effect, but also were harmless to human body.
It is said that herders in Inner Mongolia grassland use silver bowls to hold koumiss, which will not turn sour after a few days. Similarly, using a silver bowl to hold water can ensure that the water does not deteriorate. It is also said that some scientists have done experiments, using silver electrodes to treat sewage (containing more than 7000 Escherichia coli per milliliter) for 3 hours, and a large number of Escherichia coli died. For example, skin ulcers can also be coated with silver ion solution, which can kill most bacteria. Also, it is said that many airlines in the world are using silver water filters. Some swimming pools also use silver to purify the pool water. Silver purified water will not irritate the swimmer's skin.
Although wearing silver ornaments has so many advantages, everything has two sides, and silver ornaments cannot be perfect.
disadvantaged
1, silver ornaments easily react with sulfur in air and sweat. Black substance is produced, which makes the silver jewelry lose its original luster.
2, the higher the purity of silver jewelry, the softer it is, which is easy to cause certain scratches.
3. Based on the above two points, it takes more time to maintain silver ornaments.
But compared with these shortcomings, I am most afraid of buying fake silver ornaments! Do you know that?/You know what? Fake silver jewelry is equivalent to poison! The reason is small, let me explain it to you in detail!
At present, because the price of silver jewelry is generally low, many consumers don't care much about the purity of silver jewelry, so they often buy fake silver jewelry. Some consumers will buy silver jewelry for babies and the elderly to make them lucky, but the baby's skin is delicate and the elderly's skin immunity is low. Once you buy fake silver jewelry, it may bring harm to your body.
Experts say that inferior silver jewelry contains lead and chromium, which will cause skin allergies, damage the heart and liver for a long time, and even endanger life.
At present, there are generally the following kinds of fake silver ornaments on the market:
1, silver wrapping, using mechanical or other methods to wrap silver on the surface of other metal products as silver ornaments.
2, silver plating, the main material of this kind of jewelry is generally an alloy material with copper and other metals as the main material, but a layer of silver is plated on its surface to change its luster and make its appearance similar to silver jewelry.
3. "Sandwich" silver, although its surface layer is also silver, its interior is other harmful metals, such as cadmium. Long-term wear will affect the health of consumers.
Xiao Wei prompt
When choosing silver jewelry, please try to choose branded and guaranteed products. Generally speaking, brand silverware has a stamped logo representing the brand.
Don't buy fake and shoddy products on the cheap, and don't trust online identification methods, such as throwing silver ornaments on the ground to see if they bounce off and lighting them with a lighter to see if they turn black. These are all extremely unscientific ways. Have you ever thought about it? These may be fabricated by unscrupulous merchants according to the metal characteristics of inferior silver.
