Why do jade and silver ornaments all say that they can support people? How do they feed people? I hope the wise man can explain it in detail.
Jade can nourish people for a long time. Li Shizhen's Compendium of Materia Medica mentioned that taking jade tablets for a long time has the advantages of "moistening the heart and lungs, helping the voice and throat, and nourishing hair". However, since the development of science, there is no scientific reason for the saying that jade nurtures people. There is no scientific basis for the absorption of trace elements in jade through skin. At present, it is not clear what trace elements are in jade and what state they exist, so the conclusion that skin absorbs trace elements is just a fantasy.

But jade experts pointed out that it is true that people raise jade. This is because the temperature of the human body, sweat and oil secreted by the skin are all beneficial to the structure of jade, so the longer you wear it, the more transparent and bright it is. However, unlike the folk saying that jade should absorb the essence of human body to raise jade when it is first worn.

Can silverware suck out toxins from the body?

There is too much talk about jewelry. Besides jade, silverware is also covered with mysterious colors. Many people think that wearing silver jewelry can reflect the health of the body. For example, the silverware worn turns black, indicating that it is toxic in the body and may have serious diseases. And blackening silverware means absorbing toxins from the body, which can help the body recover. Experts pointed out that there is no scientific basis for this statement.

There are often scenes of silver needles detecting drugs in movies. So it can be inferred from this that whether the blackening of silver jewelry must be toxic in the body? Experts pointed out that arsenic was often used as poison in ancient times. Because the purification technology was not enough at that time, arsenic always contained some sulfur, and the chemical reaction between sulfur and silver would turn black. The blackening of silver jewelry does not prove that there is arsenic in the body and skin, but because the sulfur in the surrounding environment has increased. When sulfur reaches a certain concentration, silver will turn black, which has nothing to do with health.
