1, MM people all think wearing silver jewelry is beautiful and fashionable. Few people know that silver products have strong bactericidal ability. I didn't even know that silver had the effect of medical care.
Chemically speaking, silver is a precious metal, and its chemical element symbol is Ag. Its application in medicine and health can be traced back to 5000 years ago. Silver is widely used in the field of medicine and health because of its unique biological function.
Silver ions have a strong bactericidal effect and are very beneficial to human body. It not only has economic value and elegant appearance, but also can be used as a tool for drug detection. The ancients said that wearing silver will be accompanied by health and wealth, not only because it is a precious metal, but also because it has a higher effect on human health than gold in medicine.
Before BC, the ancients knew that silver could accelerate wound healing, prevent infection, purify water and keep fresh. It can prevent the growth of bacteria, calm the five internal organs, calm the nerves, stop convulsions and eliminate evil spirits. Silver has excellent antibacterial and bactericidal effects. Ordinary antibiotics can only work on an average of 6 kinds of bacteria, while silver can destroy 650 kinds of bacteria.
Holding water in a silver bowl can ensure that the water will not deteriorate. For example, skin ulcers can also be coated with silver ion solution, which can kill most bacteria. The ability of silver to kill or inhibit pathogenic microorganisms has been confirmed by many studies. Among antibacterial drugs, silver is unique because of its broad spectrum, and it is effective for all kinds of microorganisms, including G+ bacteria, G- bacteria, sporogenous bacteria, fungi, viruses, mycoplasma and so on.
2. Promote wound healing. It is found that silver can reduce the activity of metalloproteinases. Metalloproteinase (MMP) is a kind of protease, which exists in wounds and can decompose necrotic tissues. Under normal circumstances, MMP is in equilibrium with natural inhibitors and growth factors. The structure of MMP contains sulfhydryl groups, and the activation needs the participation of zinc ions. During burn or chronic trauma, MMP activity is enhanced. Excessive MMP activity will destroy growth factors and new tissues and hinder wound healing. Silver can combine with sulfhydryl groups in MMP structure or reduce excessive MMP activity by reducing zinc ions in wound surface. It is also reported that silver can increase the calcium content on the wound surface, and calcium can accelerate epithelial regeneration. In addition, it has been reported that silver can increase white blood cells. Before BC, the ancients knew that silver could accelerate wound healing, prevent infection, purify water and keep fresh. It can prevent the growth of bacteria, calm the five internal organs, calm the nerves, stop convulsions and eliminate evil spirits.
3, the use of silver can detect whether food is toxic, because silver can react with many toxins, making silver black and easy to identify with the naked eye. As an ornament, silver is beautiful, fashionable and beautiful. It is important that there are no radiation side effects on the body. Silver can detect many toxins, which can react chemically to make silver black, and can also react with other heavy metals to detect harmful substances, so people in poor health will use silver ornaments to make it black. At present, science has confirmed that people wearing silver ornaments turn black, which only shows that people have diseases such as rheumatism, and others cannot be detected.
The thermal conductivity of silver is the most outstanding among all metals. It can quickly dissipate the heat of blood vessels and quickly reduce the heat of blood vessels, and has excellent curative effect on preventing various diseases. Assuming that the thermal conductivity of silver is 100, that of gold is 53.2, that of iron is 1 1.6, and that of platinum is 8.2, this distinct thermal conductivity can quickly reduce the heat of blood vessels and prevent various diseases. Silver has the function of absorbing toxicity, which is one of the reasons for its discoloration, so it has excellent disinfection performance. This discoloration is only a superficial reaction and can be eliminated with toothpaste or medicine. It can be seen that the importance of silver to health cannot be ignored.
5. 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", and the pure silver bracelet is an expectation, a love and a protection for adults and children. I hope that children will grow up quickly, be healthy and lively, live a long life, go in and out safely, and so on. The unique cool and clean light of sterling silver jewelry has a wonderful finishing touch, showing elegance in silence and elegance, and has become the best gift jewelry for the care and blessing of elders for thousands of years. Besides beauty and elegance, wearing sterling silver jewelry has many advantages:
Legend has it that wearing silver ornaments can ward off evil spirits, so there has been a custom of letting children wear silver ornaments since ancient times, which is not only conducive to eliminating "fetal poison" in the body but also plays a role in ward off evil spirits.

Maintenance of silver ornaments
① Don't wear precious metal jewelry when wearing silver jewelry to avoid collision, deformation or wear.
Avoid water vapor and chemicals, avoid wearing bathrobes and pay attention to perspiration.
③ After wearing it every day, clean it with cotton cloth (especially when sweating or taking a bath) and put it in a jewelry box or bag for sealed preservation.
Solution to blackening
If the silver jewelry turns black, don't rush to wash it with silver water, because silver water is a chemical agent and has a certain corrosive effect on the jewelry. Silver cloth is your first choice. There are many small remedies, such as soaking silver jewelry in coke for the night, or brushing it with a soft brush dipped in toothpaste ... but remember to dry the water with cotton cloth after washing.
Question 5: What is silver for? Silver is one of the metals found in ancient times. Although silver also exists in the form of simple substance in nature, most of it exists in the form of combined state.
Silver has high ductility and can be rolled into a transparent foil with a thickness of only 0.00003 cm. Silver particles with a weight of 1 g can be drawn into filaments about two kilometers long.
The thermal conductivity and electrical conductivity of silver are among the best among metals.
The characteristic oxidation number of silver is+1, and its chemical properties are worse than that of copper. At room temperature, even if heated, it will not react with water and oxygen in the air, but it will turn black and lose its silver luster in the air for a long time. This is because silver and H2S in the air synthesize black Ag2S. The chemical reaction equation is:
4Ag + H2S + O2 = 2Ag2S + 2H2O
Silver can't react with dilute hydrochloric acid or dilute sulfuric acid to release hydrogen, but it can be dissolved in nitric acid or hot concentrated sulfuric acid.
hot
2Ag+2H2SO4 (concentrated) = = = Ag2SO4+SO2 =+2h2o
Silver reacts slowly with halogen at room temperature and can generate halide when heated.

. Application of silver:
Pure silver is a beautiful silvery white metal with good ductility, and its conductivity and heat transfer are the highest among all metals.
For example, the conductivity of mercury is 1, that of copper is 57, and that of silver is 59, ranking first. Therefore, silver is often used to make highly sensitive physical instrument components, various automation devices, rockets, submarines, computers, nuclear devices and communication systems. A large number of contacts in all these devices are made of silver. In the process of use, each contact has to work for millions of times, and it must be wear-resistant and reliable, and can withstand strict working requirements. Silver can meet all kinds of requirements. If rare earth elements are added to silver, the performance will be better. The contact life made of silver and rare earth elements can be extended several times.
Among all metals, silver has the best reflection performance on natural light, so silver plays an important role in the mirror industry.
In addition, silver ions can sterilize. Herdsmen in Inner Mongolia, China often use silver bowls to hold horse milk, which can be kept sour for a long time.
Element source:
The main silver deposit is argentite, followed by amphibole and natural silver. Silver is obtained by heating silver ore with salt and water, then combining with mercury to form a mixture of silver and mercury, and evaporating mercury. Or by leaching silver ore with cyanide alkali and adding lead or zinc to precipitate silver.
Element usage:
Used for making alloys, fluxes, silver foils, silver salts, chemical instruments, etc. , and used to make silver coins and base silver.
The most important compound of silver is silver nitrate. In medical treatment, the aqueous solution of silver nitrate is often used as eye drops, because silver ions can strongly kill germs.
The price is generally around 70 yuan/gram, and the purity is 999. Silver nitrate decomposes into silver when exposed to light or organic matter. Tiny silver is grayish black. This compound is used for silver plating or other silver compounds, and it is also the main raw material for making the photosensitive layer of photographic film. Silver nitrate can converge, sterilize or corrode at different concentrations. The concentrated solution of silver nitrate can corrode the overgrowth of granulation tissue, and its dilute solution can be used to treat conjunctivitis.
Silver oxide is easily soluble in ammonia water, and after the solution is left for a long time, sometimes it will precipitate a strongly explosive black crystal. Silver oxide is used as a colorant in the glass industry.
The photosensitive function of silver bromide is used to make the photosensitive layer of photographic film. ...& gt& gt
Question 6: What are the benefits of silver ornaments to health? Silver has been a symbol of wealth since ancient times, and China used it as a common currency in ancient times. Silver jewelry is also deeply loved by people, because it has the texture of platinum and the price of alloy. Accepted by the public, what are the benefits of wearing silver ornaments? 1, the best "poison detection" metal for sterling silver jewelry. It is said that "toxins" are discharged from the human body every day, and silver, a metal, can absorb these "toxins". Because the oxidation resistance and gloss durability of pure silver will change with people's physique, that is to say, people with good physique will wear pure silver jewelry, which will become brighter and brighter; People with weak constitution wear sterling silver jewelry, and if there are many toxins in the body, it will gradually lead to black silver jewelry. Therefore, wearing sterling silver jewelry often can not only help the toxins in the body to be effectively discharged, but also play a role in detecting whether there are too many toxins in the body in time. This is also one of the reasons why some people deliberately look for sterling silver jewelry to wear. 2, sterling silver jewelry, with simple, lightweight, personalized and unique health effects and other characteristics, deeply favored by fashion stars, beauty lovers, noble people. According to Compendium of Materia Medica, silver has the functions 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, there is a folk saying in many places that "relieving fetal poison can also soothe the nerves, ward off evil spirits and soothe the nerves." 3. Pure silver products can generate a magnetic field 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. However, only jewelry with silver plating on the surface and jewelry with insufficient silver purity have almost no such effect. On the contrary, if the wearer is in poor health, poisoning and allergy will occur due to chemical reaction or excessive harmful elements. 4. Because silver with purity of 99 has a strong bactericidal effect, pure silver also has the reputation of "permanent bactericide". It is said that herders in Inner Mongolia grassland use silver bowls to hold horse milk, 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, and 23 liters of sewage (containing more than 7000 Escherichia coli per milliliter) was treated with silver electrode 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 swimmers also use silver to purify the water in the swimming pool, and the water purified by silver will not * * * the swimmer's skin.
Is this ok?
Question 7: What's the use of a silver pestle? Ginkgo biloba, commonly known as ginkgo biloba, is extracted from ginkgo biloba leaves and has the function of dilating blood vessels.
Question 8: What is the function of silver? Silver ions and compounds are toxic to some bacteria, viruses, algae and fungi, but almost completely harmless to human body. argyric
This bactericidal action enables it to kill living things outside the body. However, it is very difficult to test and standardize silver products.
Hippocrates once described the role of silver in the treatment and prevention of diseases. Phoenicians used to hold water, wine and vinegar in silver bottles to prevent these liquids from deteriorating. At the beginning of the 20th century, people also put silver coins in milk to extend the shelf life of milk. The sterilization mechanism of silver has been debated for a long time, and there is no conclusion so far. Microkinetic effect is a good example, which successfully explains the effect of silver ions on microorganisms, but cannot explain its effect on viruses.
Silver is added in large quantities to gels and bandages. The antibacterial property of silver comes from silver ions. Because silver ions can form strong bonds with substances used by some microorganisms to breathe (such as some molecules containing oxygen, sulfur and nitrogen), these substances can not be used by microorganisms, which leads to suffocation and death of microorganisms.
Before the invention of antibiotics, during World War I, silver-related compounds were used to prevent infection. ..
As a widely used antibacterial agent, silver is being applied in a new way. On the one hand, silver nitrate dissolves in alginate to prevent wound infection, especially burn wound infection. In 2007, a company designed a silver-plated glass, which is said to have good antibacterial performance. In addition, the US Food and Drug Administration (FDA) also approved the application of a silver-plated airway, because research shows that this airway can effectively reduce respiratory pneumonia.
Silver is not toxic to human health, but long-term exposure to silver metal and non-toxic silver compounds will also lead to silver deposition. Because the body pigment changes, the skin surface will appear gray-blue Although non-toxic, it will still affect the appearance.
Skin contact: take off the contaminated clothes immediately and rinse with plenty of running water for 20 ~ 30 minutes. If you don't feel well, see a doctor.
Eye contact: lift the eyelid immediately and rinse it thoroughly with plenty of flowing water or normal saline 10 ~ 15 minutes. If you don't feel well, see a doctor.
Inhalation: leave the scene quickly and go to a place with fresh air. Keep the respiratory tract unobstructed. If you have difficulty breathing, give oxygen. Breathing and heartbeat stopped, and cardiopulmonary resuscitation was performed immediately. See a doctor at once.
Ingestion: drink water without vomiting. If you don't feel well, see a doctor.

Question 9: What are the advantages of wearing a silver bracelet? Silver ion has a strong bactericidal effect and is good for human body. The silver bracelet has never been worn in the store, and it has always been bright white. But once it is in contact with the human body for a period of time, it is easy to turn black when it is put back in the jewelry box. Generally, it won't turn black when worn on your hands. Silver can help us absorb more water in our bodies and make our bodies healthier. If the silverware shows signs of blackening, it means that you are in poor health. Before BC, the ancients knew that silver could accelerate wound healing, prevent infection, purify water and keep fresh. It can prevent the growth of bacteria, calm the five internal organs, calm the nerves, stop convulsions and eliminate evil spirits. Silver has excellent antibacterial and bactericidal effects.
