The research shows that mineral gems have health-preserving effect on human body in general, and they all belong to the category of mineral drugs. In China, the history of mineral medicine can be traced back to 2000 years ago, and the treatment of Bian Shi is recorded in Huangdi Neijing, so Bian Shi is also called "the first stone of external treatment of traditional Chinese medicine". In the Compendium of Materia Medica written by Li Shizhen, a medical sage in Ming Dynasty, there is a record of "the first stone of external treatment of traditional Chinese medicine". According to preliminary statistics, there are more than 20 kinds of traditional Chinese medicines related to gems. Modern scientific and technological research has also confirmed that 63% of dozens of elements contained in human blood can be found in jewelry materials. According to research, the yin and yang properties of most jewelry drugs are mainly determined by their odor, so basically all gems have the function of nourishing yin and strengthening yang. Among precious jade, the smell of jade is sweet and belongs to Yang, while the smell of gold is pungent and belongs to Yang. For example, Hetian jade with tremolite as the main mineral has an aphrodisiac effect; Bai Shiying, the main mineral of crystal, has a remarkable effect on male impotence, nourishing yin and strengthening yang. Black agate and black time also have a good effect on treating kidney and nourishing kidney yang. The rich minerals and trace elements in gems mainly diffuse into human body through digestive tract and skin. For example, the elements of pots, bowls, cups, plates and other utensils carved with precious stones enter the human body through the digestive tract. When people wear jewelry, its elements enter the human body through direct contact with the skin of earlobe, neck, chest, wrist, fingers and hairline. The negative ions emitted by gems enter through the respiratory tract and are absorbed by the human body. There are also far infrared rays, bioelectricity and other health effects, which can be "accepted" by the human body in different ways. As for the fact that wearing jade can ward off evil spirits, it is indeed a bit excessive. But from a certain point of view, if you wear priceless jewels, you will definitely have a sense of satisfaction and pride in your heart. This feeling of "contentment" and "complacency" is good for your emotional health. At the same time, if you wear this rare and expensive bracelet all day, you will always be cautious in your life, which will inevitably reduce the chance of accidents and play a "detour" role inadvertently.
