What is the familiar "saliva regimen"? Lu You, a poet in Song Dynasty, once shared his way of keeping in good health. When he was young, he aged early, his teeth fell off and his hair turned white. So, he began to do some health qigong, including "knocking his teeth and gargling". As a result, his teeth didn't fall out and his hair turned black. Is the regimen handed down by the ancients really so magical?
Li Si introduced that saliva is secreted by three pairs of salivary glands (subauricular gland, submandibular gland and sublingual gland) and buccal gland, and the daily saliva secretion is about 1 0,000 ~10,500 ml.
Xue, director of the Department of Otolaryngology, Hsinchu Guotai Hospital, pointed out that saliva has many functions. Saliva contains enzymes that can help digestion, such as salivary amylase, salivary lipase, etc., and contains a lot of water, so that the residue and bacteria attached to the tooth surface in the oral cavity can be removed. Saliva also contains antibacterial components and lysozyme, of which "immunoglobulin" is the most important and has a defensive effect on oral mucosa and dental health. A large number of enzymes and natural immune factors secreted by saliva contribute to oral health, protect oral mucosal cells and promote the health of gums and teeth.
Saliva contains many antibacterial enzymes, which are helpful for digestion and anti-aging.
Li Siyi said that there was a very important oral movement in ancient health preservation, that is, "knocking teeth and gargling body fluid", that is, through the oral movement of knocking teeth, the saliva in the mouth was secreted, and then the saliva and jade liquid (namely saliva) were slowly swallowed after gargling.
"Don't underestimate the saliva in your mouth! Li Siyi emphasized that saliva is not only rich in salivary amylase, but also rich in a variety of antibacterial enzymes to help the body eliminate foreign bacteria, and contains SOD (superoxide dismutase) enzyme, which can enhance the body's antioxidant capacity, enhance resistance, avoid free radicals and have anti-aging effects.
If you can do more oral exercises to help your saliva secretion, you can often pour saliva into your mouth and swallow it, which can moisturize your body, prevent tooth decay and improve the problem of dryness inside and outside your body!
Insufficient saliva secretion, dry mouth and bad breath.
Xue pointed out that the normal saliva secretion of human body is 500 ~ 1 1,500 ml per day, which is equivalent to 1 min 1 ml. When saliva secretion is insufficient, most patients will feel thirsty, and may also feel saliva thickening. Other symptoms include tingling in the mouth, burning sensation, dysphagia, bad breath, abnormal taste and poor sense of smell.
Li Si said that saliva is the first line of defense to protect the mouth and teeth, and it also plays an indispensable role in food digestion. People often suffer from diseases such as salivary glands or head and neck tumors. Because of radiotherapy, salivary glands are destroyed, saliva secretion is reduced, and oral cavity is dry, which leads to the aggravation of tooth decay.
Four reasons of insufficient saliva
Physiology: Breathing with your mouth open while sleeping, and feeling anxious.
Drugs: the most common cause of dry mouth, there are more than 500 drugs can cause dry mouth symptoms. The more drugs you take, the higher the probability of dry mouth. Commonly used drugs such as parasympathetic drugs, sympathetic drugs, diuretics, etc.
Sjogren's syndrome: Sjogren's syndrome, commonly known as Sjogren's syndrome, is a disease in which the immune system attacks its own body. When the immune system attacks glands that produce lubrication, such as salivary glands and lacrimal glands, it will cause dryness of the mouth and eyes.
Others, such as salivary gland radiotherapy, massive hemorrhage, vomiting and diarrhea, fever, alcohol addiction and so on. , may cause insufficient saliva.
Besides drinking plenty of water, you can also try artificial saliva, oral gel and parasympathetic drugs such as pilocarpine, sugar-free mint and nicotinamide.
Spleen deficiency and kidney deficiency, excessive saliva secretion.
According to Li Si's instrument, Neijing mentioned: "The five internal organs are fluid, the heart is sweat, the lungs are tears, the liver is tears, the spleen is saliva, and the kidney is saliva". Abnormal saliva secretion is mainly caused by spleen deficiency and kidney deficiency. Children with weak spleen are prone to drooling, and old people with weak kidneys are prone to drooling. First of all, we should find out the cause of drooling, whether it is within the normal range (for example, children are prone to drooling when teething) or caused by some dirty qi weakness in the body, and then make tonic treatment after distinguishing the syndrome types.
Xue pointed out from the perspective of western medicine that there are two reasons for excessive saliva, one is excessive saliva secretion, and the other is that the speed of saliva secretion exceeds the speed that patients can swallow.
Excessive or insufficient saliva secretion can only be improved by treatment according to the cause.
Saliva affects vitality.
Ancient health experts called the body fluid in the mouth "the water of Huachi" and "the dew of manna". Traditional Chinese medicine calls saliva body fluid, saying that "body fluid is the transformation of qi and blood, the mouth is so refined, the spleen and stomach are so abundant, and the water valley is so transformed." Li Siyi said that in modern medicine, saliva is the first step to help digestion. A famous Austrian doctor, Dr. Franz Mayer, famously said: "Nutrition = food × digestion". When food is in the mouth, it is already the first step to start the digestive system. It can be seen that the absorption of nutrients by the human body is also closely related to saliva.
Furthermore, the word "live" in Chinese characters is "tongue" with "ju" beside it, which shows the importance of saliva to vitality. Sun Simiao, a doctor in the Tang Dynasty, pointed out in "Thousands of Women": "Therefore, the imperial court took Yuquan and cut teeth, which made people strong and colorful, except for the three worms and strengthened teeth. Yuquan people, foaming at the mouth, didn't get up in the morning, washed their mouths and swallowed them early, and cut their teeth 27 times, which is a famous refined essence. 」
Saliva is divided into saliva and saliva. Saliva is born under the tongue and is born of kidney yin; Saliva is born in the mouth and transformed by the spleen and stomach. Spleen and stomach are the acquired foundation, and kidney is the innate foundation. The kidney dominates the bone and the tooth is the bone. Teeth and bones come from the same source and are nourished by the essence in the kidney. The growth and loss of teeth are closely related to the rise and fall of essence in the kidney. Therefore, knocking at the door often can not only strengthen the kidney and teeth, prevent teeth from loosening and gingival atrophy, but also strengthen bones and prevent aging phenomena such as osteoporosis, which can be said to have many effects.
The magic prescription of tapping teeth to relieve body fluid
"Swallowing the mouth and nourishing the body fluid" is the so-called "it is inevitable to supplement the true yin with real water and seek common ground". However, swallowing oral liquid can not only nourish the kidney's true yin, but also subdue the heart fire, so that dry Kun can make friends with Thailand and make fire and water auspicious. Saliva regimen is especially suitable for patients who can't sleep well for a long time, are prone to dry mouth and have fragile teeth.
Li Siyi proposed the method of "chewing teeth and gargling body fluid" to strengthen teeth. This exclusive dental exercise can help strengthen gums and teeth and help you "massage" your teeth when you are still in bed after getting up every day.
The practice is as follows:
Breathe five times after waking up in the morning, and there will be turbid air in the abdomen.
Knock on your teeth with your eyes closed 16 or 36 times.
The tongue touches the upper jaw, bulges the cheek to make it full of body fluid, and slowly swallows it three times.
Repeat the above actions for 3 times.
Five functions of saliva
Saliva secretion helps to rinse the oral mucosa and keep the mouth clean.
Carbonate, phosphoric acid, urea and acid-base protein in saliva can be used to neutralize the acidity of food and maintain the neutral environment of pH 6 ~ 7 in oral cavity.
Saliva can protect teeth by demineralization and remineralization.
Saliva is secreted by immunoglobulin, especially IgA, which can neutralize virus and bacterial antigens and inactivate them. Others are lactoferrin, lysozyme, peroxidase and mucin.
