What does saliva do

Saliva has a health-care effect on the body, and it has been valued and affirmed by medical doctors and health practitioners since ancient times, which can be seen from the aliases of saliva, such as "Jinjin", "Yuju", "Qiongju This can be seen from the aliases of saliva, such as "Jinjin", "Yuyu", "Qiongju", "Ganju", "Huachi Shenshui", etc., which are all beautiful names for it. What are the functions of saliva?

Saliva has the effect of strengthening the body

Parotid hormone is the most attractive substance contained in saliva. Parotid hormone can increase the vitality of muscles, blood vessels, connective tissues, bones, cartilage and teeth, especially strengthen the elasticity of blood vessels and improve the vitality of connective tissues. As long as the parotid hormone is full, the function of blood vessels and skin interstitial and connective tissues will be strengthened, and the elasticity of the skin will be maintained. After entering middle age, the parotid gland begins to shrink and the secretion of hormones gradually decreases. Swallowing saliva often can delay the atrophy of the parotid gland.

Saliva has a digestive function

The amylase enzyme in saliva helps digestion by breaking down the starch in food. When eating acidic foods, salivary glands are stimulated to produce large amounts of saliva to neutralize the acidic foods. When eating dry food, a large amount of water in saliva can dissolve the food to help lubricate and swallow the food, so that the food is diluted and lubricated before it enters the stomach and intestines, which helps further absorption and digestion.

Saliva has a cleansing and antibacterial effect

Saliva can rinse food debris from the teeth, and the month which contains lysergic acid and antibodies can inhibit the growth of bacteria in the mouth and the formation of tooth decay. Those who have dry mouth are unable to clean the debris and bacteria, so the build-up of decay in the mouth is very likely to cause bad breath and subsequent tooth decay.

Saliva is involved in the regulation of body fluids

When dry mouth occurs, saliva is secreted in large quantities to increase the moisture content of the mouth, and if the body has too little water to produce saliva, thirst will develop. This desire to drink water to quench thirst can indirectly regulate the body's water content.

Saliva can promote wound healing

Experience tells us that after the tongue and lips are squeaked, the wound door heals much faster than other parts of the injection. Animals also often lick their wounds with their tongues after being injured. This is all because saliva has anti-inflammatory and pain-relieving, hemostatic, antiseptic and detoxifying effects.

Saliva has a beautiful skin effect

Medical research has found that saliva has some components that are the best nutrients for skin cells and do not cause skin allergies; saliva contains a variety of biological enzymes, such as lysozyme and amylase, all of which are weakly alkaline and can eliminate the oil secreted by facial skin, kill some bacteria on the face and avoid boils and spots on the face. Therefore, using saliva to apply on the face often has unexpected effects.

Composition of saliva

Saliva is secreted from the parotid, submandibular and sublingual glands in the mouth. It consists of salivary enzymes, water, antibodies, proteins, inorganic substances, calcium phosphate, sodium carbonate, calcium carbonate, magnesium phosphate and potassium chloride, etc., of which water accounts for 98.5%~99.0%.

The ph value of saliva

Normal people secrete 1000~1500ml of saliva every day, and normal saliva is colorless, tasteless and nearly neutral (pH 6.6~7.1). The following section will focus on the role of saliva.
