Silver not only has economic value and elegant appearance, but also can be used as a drug detection tool. 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.
Using silver can detect whether food is toxic, because silver can react with many toxins, making silver black and easy to be recognized by the naked eye.
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 act on 6 kinds of bacteria on average, while silver can kill many kinds of bacteria. ?
Some people wear silver and it is not easy to change color because everyone's endocrine structure is different. Some people have more acid in sweat, some people have less, and some people have high ammonia content, so wearing silver ornaments has different effects. Acidic ones are easy to black, and non-acidic ones are not easy to black. Even some people with exuberant oil secretion will bring their own silver ornaments to shine.
