"Jade can support people" is an ancient and modern problem. Can jade support people? This sounds a bit ridiculous. This reminds me of a question raised when I was a child, that is, people are eating the sun. Of course, this kind of eating and drinking is not eating and drinking in the direct sense. I remember that the book "100,000 Why" at that time answered the question "People eat the sun", which was also very simple. Everything grows on the sun. Without the sun, the earth would not become a desert. Is there anything for people to eat? Knowing this problem, the problem of "nurturing people with jade" will be better understood. Natural jade has the saying of "ten treasures and nine cracks", because most natural jade has cracks, which can absorb human body fluids after long-term wear, making jade moist and transparent, and the water color is bright and shiny; At the same time, minerals in jade permeate the human body and can nourish people's lives. People who wear jade for a long time will have the same moral character as jade. Therefore, in ancient times, there was a saying that "a gentleman is gentle as jade", "a gentleman never leaves his body for no reason", and "a gentleman produces fragrance like jade, and beautiful jade contains fragrance for a long time". Pharmacologically speaking, wearing gems for a long time can keep the balance of various elements in the human body, and different gems have different functions. According to the research of mineral medicine, some gems can produce high-intensity photoelectric effect, and their diffraction force can release huge energy enough to affect human bioelectricity and regulate metabolism. The special photoelectric effect of gems can resonate with the human body. Some gems have been carefully cut and polished, which have the function of centralized energy storage, absorbing light during the day and emitting light at night. If the light spot is aimed at a certain acupoint, it can stimulate the meridians and dredge the viscera, which will have a more peculiar curative effect. Mouth contains jade, which can promote fluid production, dissolve bacteria, quench thirst, remove stomach heat, relieve dysphoria, nourish heart and lungs, moisten throat and care hair. Gems can also inhibit fungi, so they can treat facial scars and human allergies. Recently, some precious stones have been found to have subtle mineral physical functions. For example, diamonds can "ward off evil spirits and drive away toxic gases", because they can absorb the short-wave band of sunlight, thus becoming an ideal "storage" of ultraviolet rays, so they have a disinfection and sterilization effect on the human body; Sapphire can relieve respiratory diseases; Olivine can cure thirst or dizziness caused by asthma and high fever; White marble can remove blood stasis and stop bleeding; Turquoise and lapis lazuli can detoxify; Crystal, in Shan Hai Jing, was once called water jade, water essence, bodhisattva stone and so on. Li Shizhen, a great medical scientist, recorded in Compendium of Materia Medica that crystal is "pungent and cold, non-toxic", which is mainly used for "frightening the wind and clearing away heat, calming the heart and improving eyesight, removing red eyes, refreshing the brain, facilitating defecation, nourishing viscera, lowering blood pressure, warming the lungs and kidneys, ironing and rubbing obstacles", and can also treat "lung pain, vomiting pus, relieving cough and raising qi, and pleasing the color" and other magical effects. The article "Medical Function of Jade" also introduces the health care function of jade to human body. At the same time, modern science also shows that crystal also contains trace elements such as iron, magnesium, copper, manganese, titanium, zinc, nickel and cobalt, which are beneficial to human body. Crystal also has a weak electromagnetic field, which can stabilize people's mood and enhance their adaptability. Jade is made of gem minerals. Gems generally have four characteristics: beautiful, durable, rare and valuable. There are thousands of minerals in nature, of which only 100 are beautiful and durable, suitable for processing, and only a dozen can be used as jewelry. The chemical composition of jadeite is mainly composed of hydrated silicate, containing trace elements such as sodium, calcium, magnesium and aluminum. Jade is mainly formed by igneous rock crystallization, which is recrystallized by high-temperature melting metamorphism. The jade formed by the above two actions is washed, transported and deposited by running water, and then mixed with gravel to form placer and sedimentary ore of jade. Jade has various colors. For example, the most precious white jade is white, delicate and flawless suet jade. Green is the treasure of jade, with purity and suitable shade as the top grade, preferably the green of Hollyleaf reflected by sunshine after rain. There are other colors such as black, gray, yellow and red, but they all require transparency, delicacy, crystal, compactness and exquisiteness. China has been known as "the country of jade" since ancient times. The ancients regarded jade as a treasure and regarded it as a precious ornament. Ancient medical books said that "jade is the beauty of stone, sweet and non-toxic", and that jade is the most abundant substance for human health. Therefore, jade is not only used as jade locks, jade fingers, bracelets, anklets, hanging chains, snuff bottles, decorations and decorations, but also used for health preservation and fitness. From ancient times to the present, emperors and concubines of various dynasties did not need jade for health preservation, such as eating jade in Wei, Jin, Southern and Northern Dynasties, Song Huizong was addicted to jade, and Yang Guifei used jade to cure summer heat. Modern science and technology show that jade contains trace elements beneficial to human body, such as zinc, magnesium, copper, selenium, chromium, manganese and cobalt. Wearing jade regularly can make human skin absorb trace elements, which is helpful to the coordination and balance of physiological functions of human organs. Some jade has the physical characteristics of absorbing light during the day and emitting light at night. When the jade spot is aimed at a certain point in the human body, it can stimulate the meridians and dredge the viscera, which has obvious health care function. There is a "pension hole" on the back of the old man's wrist. Wearing jade bracelets can play the role of massage and health care, which can not only improve the symptoms of blurred vision of the elderly, but also store vitality and nourish the spirit. The oral cavity contains jade. With the help of the synergistic effect of the nutrients contained in saliva and lysozyme, it is helpful to promote fluid production to quench thirst, remove stomach heat, relieve annoyance, nourish the heart and lungs, moisten the throat and raise hair, and store qi to nourish the mind. In addition, the beautiful wine glasses made of green sapphires and sapphires not only have beautiful appearance, but also have the function of wine, which can change the structure of wine and make it mellow, sweet, soft and palatable. Eight special terms for jade cultivation: 1. Rubbing jade: it is to wipe the surface of jade with a clean soft towel or sheepskin, which can achieve a certain effect of raising jade. 2. Pan Yu: By playing with hands or rubbing your face, the skin surface of human body consciously rubs. But people's skin is oily, and the jade should be wiped off with a clean soft towel after it is put on the plate. 3. Raising jade: Pay attention to normal wettability, including rubbing jade and plate jade. Wearing ornaments and bracelets has a certain moisturizing and permeability effect on the interior and surface of jade. 4. Repair: Damaged jade pieces should be repaired in time to meet the requirements of jade cultivation. 5. Restoration: For the restoration of some places exposed to strong sunlight (ultraviolet rays) or indoor glare for a long time, the adsorbed water on the jade surface can be restored after being placed in a humid room for a period of time, and the moisture and brightness can be restored to a certain extent after being wiped with a soft cloth, or the above effect can be achieved by putting a glass of water in Bo Gu cabinets and counters. 6. Water replenishment: refers to the loss of adsorbed water and intermolecular water on the jade surface due to over-polishing, and its surface structure is damaged to a certain extent, which is called nonmetallic "fatigue", which shows that the jade surface is dry and bright. The better methods are "plate jade" and "soil soaking", which can achieve the effect of replenishing water after being placed in soil with certain humidity for a period of time. Or use the original bamboo to polish it again, which can also achieve a certain hydrating effect. 7. "Repair": In order to reduce the cost of polishing, some manufacturers use some cheap green powder to polish the jade surface, which will "burn" the green part of the jade. The recuperation method is to wash off the green powder on the surface of jade with hot water and washing powder, then wash it thoroughly with hot water and transparent soapy water, dry it, and polish it again with raw bamboo and diamond powder to restore the original appearance and natural characteristics of jade, and also achieve the effect of raising jade. 8. Bogey: avoid collision damage, keep it properly, avoid contact with acid and alkali items, and avoid long-term strong light irradiation, so as not to damage the surface structure of jade.
