Jade has always been loved by people. In China, it is said that jade can ward off evil spirits and keep peace. According to legend, jade can give off a special luster, which is hard to see during the day and can illuminate the garden several feet in Fiona Fang at night. This kind of luster is what monsters fear most. Therefore, emperors used to hold water to show strict protection of health, and ordinary people also like to wear jade for peace. Modern scientific research shows that jade contains elements beneficial to human body, such as jade bracelets, necklaces, rings, jade mats, jade pillows, etc. It is often worn and used. Because of the friction between skin and acupoints, it has many benefits to the skin of meridians and blood vessels, and has the effect of preventing diseases and treating diseases. Therefore, it is very beneficial to use jade as an amulet. Jade is a rare treasure. Jade contains more than 30 kinds of trace elements beneficial to human body, such as selenium, zinc, nickel, cobalt, manganese, magnesium and calcium. The starting waves emitted by these elements are in the same fluctuation state as those of human cells, and human cells produce * * * sounds and * * * vibrations with the fluctuation of jade, which makes human cells more energetic, promotes blood circulation and enhances metabolism. Among them, 40% magnesium is one of the main components that form chlorophyll, and magnesium also exists in human cells. Jade can turn drinking water and natural water into active water and help people improve their immunity. The medical fitness function of jade on human body has long been discovered by human beings. There are works in Shennong Herbal Medicine, Tang Herbal Medicine and Compendium of Traditional Chinese Medicine in China. According to the eighth volume of Compendium of Materia Medica-Epistemology, jade has the following therapeutic effects: removing stomach heat, relieving asthma, nourishing hair, nourishing five internal organs, softening tendons and strengthening bones, quenching thirst, moistening heart and lungs, helping voice and throat, calming the heart and calming the nerves, benefiting blood vessels and brightening eyes and ears. According to the health-care function of jade to human body, jade pillows, shoes, balls, necklaces, cushions, backs and mattresses certified by the ISO9002 international system are innovatively developed by using the classic theory of traditional Chinese medicine combined with modern scientific and technological means, which is recognized as an invention of "world significance" and shared by the whole world. Its health care mechanism is that the wavelength of electromagnetic waves emitted and absorbed by any substance is the same, and the wavelength of infrared electromagnetic waves emitted and absorbed by human body is generally 8- 10μm, with a peak value of 9.4μm m. Spectral analysis shows that xiuyan jade's special molecular structure makes it emit infrared electromagnetic waves that can be well absorbed by human body (as shown in the figure). The wavelength is in the range of 8- 10μm, and the peak value is 9.9 μ m. This effect is usually called * * * vibration absorption, or partially matched absorption. This magnetic wave can produce excellent biological effects, that is, improving circulation, stimulating regeneration, improving enzyme activity, restoring physiological functions, strengthening cell phagocytosis and antibody production. But wearing fake jade is harmful to your health. Relevant experts reminded that people should be cautious when buying jade, and poor selection will also affect their health. Wang Chunsheng, a senior engineer of the National Center for Quality Supervision and Inspection of Jewelry and Jade, believes that jade is generally divided into three kinds of goods: A, B and C. A refers to the jade with original stone color, which is untreated and has a higher price. Goods B are jade articles filled with resin after chemical bleaching, and the price is cheaper. C jade color difference. When it is heated to 1 10℃, it is soaked in chromium salt solution for one or two days, so that chromium salt can penetrate into the cracks of jade to achieve the dyeing effect. At first glance, it is crystal clear and will fade in a year or two. This jade is cheap and fine, but it has no collection value. What is common in the market now is B+C goods, which are processed by the synchronous combination of B goods and C goods. Wang Chunsheng said that A goods are natural jade, and its constituent elements are relatively fixed, which is generally harmless to the human body; The resin in B goods will not be affected by external forces, and generally it will not be too harmful; After B+C or C goods are dyed, the acid solution may be harmful to the skin, because some businessmen may use strong acids such as hydrofluoric acid, nitric acid, sulfuric acid and hydrochloric acid to imitate the guqin color of jade, and then coat the surface of fake ancient jade with a layer of floor paint, crystal paint or epoxy resin. Hao, director of the Department of Occupational Poisoning Medicine, Chaoyang Hospital, Beijing, believes that the interaction between resin and strong acid is easy to cause irritation, and contact dermatitis will occur after contact, with symptoms such as redness, tingling, itching and peeling. People with sensitive skin are most prone to symptoms. Both experts suggested that it is best to wear natural jade without chemical treatment for health and safety.
