Jade and physical and mental health: Jade has been a precious ornament that people like since ancient times, especially in China. As early as the Qing Dynasty, jade was regarded as the national stone of China by domestic grandfathers. It has the reputation of "Yellow Emperor Jade" and "King of Jade". Jade is regarded as a symbol of luxury with diamonds, pearls and precious stones because of its gorgeous, rare and high value. Usually, the colors of jadeite diamonds have certain connotations and meanings, which are their own personalities. For example, white (diamond, pearl, crystal) represents purity, sacredness and elegance; Blue (aquamarine, turquoise, lapis lazuli) represents beauty, tranquility and freshness; Yellow (topaz, tourmaline and topaz) means tenderness, brightness and happiness. However, jade is red, indicating enthusiasm, strength and hope; Green means peace, youth and vitality. It is precisely because the color and character of jadeite symbolizes vitality, wealth and longevity, and it concentrates the personality characteristics of the Chinese nation, so it is especially loved by Chinese people. As we all know, jadeite diamond jewelry is used as various styles of jewelry and craft products. In addition, it also has many functions in industry and medical care. Diamond (uncut "diamond" original stone, Mohs hardness 10, absolute hardness 10000Kg/mm2, specific gravity 3.25), crystal (chemical composition SiO2 _ 2, Mohs hardness 7, specific gravity 2.65), ruby (chemical composition al2o 3, Mohs hardness 9, specific gravity) Among them, diamond is the hardest substance in the world, which has the characteristics of high refractive index and strong dispersion, so about 80% of the original stone is used in industry. Crystals have a wide range of industrial uses, such as grinding glass and making important parts of electronic instruments, such as crystal chips in crystal oscillators; Because its hardness is not easy to scratch, it can penetrate ultraviolet rays, and it is also an important raw material for optical industry. Another example is the world-famous eight-treasure inkpad. Eight precious raw materials contain rubies, corals, crystals and pearls. As for the application in the medical field, the curative effects of pearls, amber, corals, etc. As early as in the classics of traditional Chinese medicine, it has been recorded that pearls can "soothe the nerves, stop nocturnal emission, remove acne and cure poison"; Amber can "dispel blood stasis and relieve stranguria"; Coral can "relieve epilepsy and improve eyesight". Now there are Chinese patent medicine "Zhubei Dingchuan Pill" and medical beauty products such as pearl cream, amber, and so on. Since ancient times, it has been said that wearing some jewelry, such as coral skewers, has magical protection skills such as "relieving shock and preventing evil spirits", "driving away disasters and avoiding risks" and "promoting midwifery". Although superstitious, it has not been empirically tested so far, so it is difficult to give a scientific appraisal, which needs to be discussed later. At present, relevant scholars have made a preliminary observation on jadeite from the perspective of health preservation, and think that it has some connection with health preservation (taking health preservation, keeping health, preventing and treating diseases). Emerald belongs to the pyroxene family, and its main chemical composition is Aina [〔Si2O6〕]. According to the basic principle of bodybuilding, the chemical elements in the material world have both positive and negative effects on the internal and external environment of the human body; Some of them can promote health, while others will harm health. O and H2O are the basis of life and indispensable substances in the process of maintaining life; Arsenic, HCN and carbon monoxide can cause people to die from arsenic, cyanide poisoning or gas poisoning, which seriously threatens their health. Looking at the components in jadeite jade, after preliminary analysis, there are no compounds harmful to the body, and some are necessary to maintain normal function. ? In ancient China, wearing jade as a talisman to ward off evil spirits and avoid disasters, from the perspective of mental health, people can look forward to a happy life and pray for health and longevity. This folk tradition continues to this day, and it is common in southern China, especially in Guangdong, Fujian, Taiwan Province and Hongkong. Generally speaking, the chemical components in jadeite can compensate the human body, which is conducive to enhancing immunity and improving metabolic function, thus improving physical and mental health and playing a preventive and robust role. Its mechanism is similar to the popular magnetic therapy tablets, health watches and fitness balls. Observation shows that wearing a jade pendant (without gold and silver inlay) on the chest is better. According to the tracking, if the jade pendant is placed on the meridian points on the chest, close to the strange points of "Longjiao" and "Shenfu", the reaction points and feelings on the body surface will be particularly ideal for guiding along the meridians. Because acupoints are the parts where qi and blood in the viscera, meridians and collaterals infuse the body surface, they have both preventive and therapeutic effects. "Dragon jaw" and "Shenfu" are the main acupoints in acupuncture to prevent and treat chest tightness, heartache and gastropathy (stomach cold, nausea, spasm, ulcer pain, etc.). ). In the same way, if the jade bracelet clings to Neiguan, Shenmen, Tongli, Gaogu and other acupoints, it will play a role in calming the heart and calming the nerves, relaxing muscles and activating collaterals; Green circles with stirrups around the middle finger, such as "Zhong Kui", "Zheng Zheng" and "Zhong Ping", help to improve the digestive system, prevent malnutrition and curb nausea and vomiting. It should be pointed out that there are many fake jadeites on the market at present. With the improvement of modern technology, these counterfeits are often confused with the genuine ones and need to be carefully identified. All counterfeit products without component analysis should not be attached to the body or decorated to prevent toxic elements from damaging physical and mental health.
