As early as 2000 years ago, people in China used jade for medical treatment. For example, it is recorded in ancient medical classics such as Shennong Materia Medica and Compendium of Materia Medica: Jade has the functions of "removing middle heat, relieving annoyance, moistening heart and lungs, helping voice and throat, nourishing hair, nourishing five internal organs, calming the heart and calming the nerves, dredging blood vessels and brightening eyes and ears"; There are 106 kinds of jade used for internal and external treatment. It is also recorded that Yuruo is "enduring cold and heat for a long time, not hungry or immortal".
According to modern biological, physical and chemical analysis, many jade articles contain more than ten kinds of trace elements beneficial to human body, such as gold, silver, silicon, zinc, iron, selenium, magnesium, manganese, etc ... Because jade science is the most abundant substance for storing "qi", wearing jade articles often can make the trace elements contained in jade inhale into human body through the skin, thus balancing the imbalance between yin and yang, qi and blood, and making people get rid of diseases, maintain health and prolong life. Zinc in hair can activate insulin, regulate energy metabolism, maintain human immune function, promote children's intellectual development, and have anti-cancer, anti-deformity and anti-aging effects. Manganese can resist the damage caused by free radicals, participate in the synthesis of protein and vitamins, promote blood circulation, accelerate metabolism, resist aging, and prevent Alzheimer's disease, osteoporosis and atherosclerosis. Selenium is a component of glutathione peroxidase, which can catalyze the reduction of toxic peroxide into harmless hydroxyl compounds, thus protecting biofilm from its harm and playing an anti-aging role; It can also alleviate the toxicity of harmful heavy metals such as cadmium and lead to human body, enhance human immune function, improve the body's disease resistance, and achieve the role of preventing and treating cancer.
Because Hetian jade and jadeite belong to jade, they are a collection of minerals. At present, after scientific appraisal, we can only say that they absolutely contain no harmful or even radioactive components, and they are the best products to wear and decorate because of their profound cultural heritage and beautiful appearance.
Health-preserving efficacy is generally the selling point of merchants, and some books point out that these two kinds of jade do contain some ingredients that are beneficial to human body and even have health-preserving effect, but they cannot be generalized. Therefore, I can only say: believe it, believe it if you don't believe it, it depends on the individual. However, perhaps when this "selling point" becomes a beautiful expectation, it may really have some magical effects of reversing Gan Kun, because we believe that all good wishes may be realized after expectation and hard work!
