As early as more than 2,000 years ago, the Chinese people used jade for medical care. For example, it is recorded in ancient medical classics such as "Shen Nong's Materia Medica" and "Compendium of Materia Medica": jade can "remove moderate heat, relieve irritability, moisten the heart and lungs, help the voice and throat, nourish the hair, nourish the five internal organs, soothe the soul, soothe the blood vessels, and brighten the eyes." There are 106 kinds of jade used for internal and external treatment. It is also recorded that if jade is "taken for a long time, it can withstand cold and heat, you will not be hungry, you will not age and you will become a god."
According to modern biological, physical, and chemical analysis: many jade stones contain more than ten trace elements that are beneficial to the human body: such as gold, silver, silicon, zinc, iron, selenium, magnesium, manganese... Because jade Xue is the substance that stores the most abundant "qi", so wearing jade regularly can cause the trace elements contained in jade to be absorbed into the human body through the skin, thereby balancing the imbalance of yin and yang, qi and blood, and making people cured of diseases, healthy and longevity. For example, zinc can activate insulin, regulate energy metabolism, maintain the body's immune function, promote children's intellectual development, and has anti-cancer, anti-deformity, and anti-aging effects. Manganese can resist the damage caused by free radicals to the human body, participate in the synthesis of proteins and vitamins, promote blood circulation, accelerate metabolism, anti-aging, and prevent Alzheimer's disease, osteoporosis, atherosclerosis, etc. Selenium is a component of glutathione peroxidase, which can catalyze the reduction of toxic peroxides into harmless hydroxyl compounds, thereby protecting biofilms from harm and playing an anti-aging role; it can also Harmful heavy metals such as cadmium and lead are poisonous to the human body and can enhance the body's immune function, improve the body's disease resistance, and achieve the effect of preventing and treating cancer.
