Saliva secretion is controlled by human cerebral cortex, and is also influenced by diet, environment, age, mood or salivary gland lesions. Washing saliva and swallowing saliva, known as "fetal food" in ancient times, is a method advocated by the ancients to keep fit. Chinese medicine believes that saliva is a natural tonic closely related to life. Human saliva contains many substances beneficial to human health, including amylase, lysozyme, peroxidase, mucin, phospholipids, phosphoprotein amino acids, sodium, potassium, calcium, magnesium and other substances. These substances have the functions of digesting food, sterilizing, resisting bacteria and protecting gastric mucosa. Swallowing your own saliva every day can cure diseases and prolong life. . Saliva contains a hormone that keeps people young and can enhance the vitality of muscles, muscle tubes, bones, cartilage and teeth. Saliva has a strong disinfection and sterilization ability, which can effectively kill carcinogens in food. Saliva also contains a special saliva growth factor, which can promote the growth and division of human cells, shorten the healing time of skin wounds and protect the elasticity of skin.
"Su Wen Xuan Ming Wu Qi pian": "Spleen is fluid and kidney is saliva". Saliva is mainly spleen and kidney, which is the foundation of congenital and acquired, and is closely related to health and longevity. Li Shizhen said: "There are four orifices in the sublingual cavity, the second orifice connects the heart qi and the second orifice connects the kidney qi. The flow of the heart under the tongue is the spirit fluid. In Taoist language, golden manna overflows in a pool, gathers in a pool, disperses in body fluid and drops in manna, so it irrigates viscera and moistens limbs. Therefore, the self-cultivation family swallows Tianjin and accepts gas, which is called clear water to fill the spiritual roots. " "Burning Snow in a Red Furnace": "If body fluid is swallowed, blood will be turned into painstaking efforts, eyesight will be improved in the liver, mind will be nourished in the spleen, qi will be helped in the lungs, and the essence will be produced in the kidney, and the bones and muscles will be naturally calmed down, so all diseases will not be born."
1. Digestive function: After food enters the mouth, it first mixes with saliva to form chyme. Amylase in saliva decomposes starch in food into maltose and then into glucose, so that food can be preliminarily digested.
2, cleaning effect: a certain amount of saliva will be secreted every day, saliva contains a lot of water, constantly flowing in the mouth. Because saliva keeps flowing, the surface of teeth is kept clean. The increase of saliva after eating can also accelerate the dissolution of oral food residues and sugar and reduce the accumulation of bacteria. Enzymes in saliva are also beneficial to remove insoluble sugars in the mouth.
3, moist mouth: easy to speak and swallow, clean and protect oral mucosa; When you love to kiss, you will be beautiful because of the wetness of saliva, and you will feel distressed because of thirst.
4. Dissolve food: Dissolve food and constantly remove food particles from the taste buds, so that you can constantly taste the taste of food.
5, antibacterial effect: saliva contains amylase, lysozyme, peroxidase, immunoglobulin, mucin, these are effective ingredients against bacteria, all have a certain antibacterial effect, often maintaining normal saliva secretion is conducive to the health of the body. Moreover, there are substances in saliva that inhibit glucan synthesis, which can hinder the formation of plaque matrix and is also good for preventing dental caries.
6. Protecting teeth: the important role of saliva in oral functional activities. In fact, the quality of saliva is very important for the health of teeth. Saliva is to teeth what cells are to blood, and there is a close relationship between them in nutrient supply and ion exchange. Relying on this relationship, the tooth obtained further mineralization of enamel and gained strong disease resistance. At the same time, saliva also provides basic conditions for the formation of dental caries. In the process of dental plaque formation, saliva mucin constitutes the early acquired membrane of dental plaque, and the agglutinating factor in saliva also promotes the adhesion of bacteria during dental plaque formation. Increasing the flow rate and amount of saliva can reduce the chance of bacteria adhering to the tooth surface, and improving the buffering capacity of saliva can neutralize the acidic substances in dental plaque. Drinking more water and eating alkaline substances in moderation can enhance the caries prevention ability of saliva by regulating good mental state.
7, protect the digestive tract: saliva cleans the mouth, protects the teeth, and has the effect of neutralizing gastric acid and repairing gastric mucosa.
8. Inhibit tooth demineralization: promote the remineralization function of teeth. Under normal circumstances, saliva contains a certain amount of minerals, such as calcium, phosphorus and fluoride ions, which can inhibit tooth demineralization and promote remineralization. Among them, fluoride in saliva is more important to assist the remineralization of enamel. Saliva protein adsorbed on the tooth surface can also prevent the loss of minerals and the attachment of bacteria, prevent acidic substances from spreading into the enamel and protect the enamel. Saliva can buffer acid, promote remineralization and help prevent dental caries.
9. Detoxification: saliva and food are fully mixed, and the toxicity of carcinogens can be invalidated through chemical changes in the mouth, so it cannot cause cancer. Known as a natural anticancer agent, there is a saying that eating slowly and prolonging life.
10. Buffering effect: Saliva has buffering and neutralizing effects on acid, which mainly comes from a buffering agent called bicarbonate contained in saliva, which can enhance the buffering effect of acid and neutralize the organic acids produced in dental plaque.
1 1. Promote wound healing: Saliva contains various components, enzymes, vitamins, minerals, organic acids and hormones in plasma, such as secretory immunoglobulin, amino acids and salivary gland hormones. These substances can promote cell growth and restore wound healing, which is also the reason why many animals lick their injured bodies after being injured.
12. Anti-aging: Swallowing saliva can really make people healthy and live longer. "Nourishing and Longevity Record" points out: "People who eat Yuquan can prolong life and eliminate all diseases." "Life-prolonging Book" says: "The body fluid in your mouth is rich in gold and jade, but you don't spit it all day long, which makes people stay energetic and shine." These effects have been confirmed by the long-term practice of health preserving and qigong practitioners in past dynasties. In addition, saliva can prevent and treat diseases and promote wound healing. The truth that swallowing saliva can prolong life has been confirmed by modern science. Saliva contains various components in plasma, including 10 enzymes, nearly 10 vitamins, various minerals, organic acids and hormones, such as secretory immunoglobulin, amino acids and salivary gland hormones. Among them, salivary gland hormones can promote the growth and division of cells, accelerate the completion of intracellular deoxyribonucleic acid, ribonucleic acid and protein, and delay the aging of human functions. Always keep saliva exuberant and directly participate in the metabolic process of the body, thus improving the functions of hair, muscles, bones and muscles, blood and organs, enhancing immune function, preventing diseases and achieving the purpose of prolonging life.
Attachment: Jin Shuyan's salivary technique
Sit still, close your eyes slightly, get rid of other thoughts, adjust your breathing to be quiet, and think about your abdomen. Lick the upper palate or extend your tongue to the outside of the upper teeth, licking it up and down and left and right to promote saliva secretion. The ancients called it "the Red Dragon stirs the Tianchi Lake". When the saliva is full, slowly swallow body fluid three times, exhale slowly, and send it to the abdomen with your mind. Or synchronized with tapping, the effect is more obvious after tapping. Long-term persistence, full of vitality, no fading face, bright eyes and ears, and longevity.
