The physiological functions of saliva are various. It can not only moisten and clean the mouth, but also the amylase in it can mix and decompose food into malt sticks to help digestion; Lysozyme can inhibit the growth and reproduction of bacteria in oral cavity; Calcium phosphate can promote tooth calcification and repair tiny holes in teeth; Mucin can neutralize part of gastric acid. People who chew slowly can not only reduce the burden on the stomach, but also significantly reduce the incidence of gastric ulcer because of increased saliva secretion.
When autumn is "dry", you will feel thirsty, your lips are always dry and the taste is boring. Especially if you talk too much, you are more prone to hoarseness and feel "angry" in your throat. Therefore, preserving body fluid is the fundamental measure to prevent dryness. Drinking water is the best way to rehydrate, but there is already a lot of water to drink. Why are your lips still dry? This is mainly due to the lack of attention to water saving. Although you drink a lot of water, soup and porridge, when it comes to work, you will get angry because of a little thing, or if you speak in front of people, it's no use drinking more water-your lips are still dry. So, don't spit at will. In autumn, eat more anti-dry food and less dry food, and then grasp yourself from the whole body and emotions. Don't let the heart fire rise and burn the body fluid, so as not to be "dry". In addition, you can eat some Sydney and Yali pears. Raw food can clear fire, while steamed food can nourish yin. You can also take Qiuli ointment, Ziyin Qingfei ointment, Guiling ointment and other soft foods to benefit the stomach and promote fluid production.
