At present, the research has not confirmed that jadeite has the function of radiation protection, but wearing jadeite is really good for your health. 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 [Si206]. According to the basic principle of health science, the chemical elements in the material world have both positive and negative effects on the internal and external environment of human body, and some of them can promote health. After analysis, jadeite contains essential components to maintain normal function. 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. It is found that if the jade pendant is placed on the chest meridian points, close to the strange points such as "Longjiao" and "Shenfu", the body surface reaction point and the guiding phenomenon of sensation transmission along the meridian are particularly ideal. 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, Ruocui bracelets cling to points such as Neiguan, Shenmen, Tongli and Gaogu, which play the role of calming the heart, calming the nerves, relaxing muscles and activating collaterals.
