1. Saliva has certain bactericidal effect.
The saliva secreted by our body contains many trace substances, including polysaccharides, amino acids and various enzymes. It contains a substance called lysozyme, which can help us keep our mouth clean and tidy in our daily diet and life. There is even an exaggerated saying that this lysozyme in saliva also has a certain bactericidal effect on some carcinogens.
2. Saliva has the function of diminishing inflammation and stopping bleeding.
Nowadays, people will use a band-aid as long as they have some minor wounds. In the past, people liked to lick wounds with their own saliva. In fact, this has certain scientific basis. Because our saliva contains a hormone, which can stop bleeding and accelerate wound healing. So in fact, when we have some bleeding in our daily life, our saliva will help us deal with these wounds. Therefore, wounds in the oral cavity can usually heal in a short time.
Saliva helps to enhance the vitality of our bodies.
Saliva also contains a hormone, which can promote the hematopoietic system in our body to play a better role, thus helping our body to eliminate more metabolic waste, thus achieving the effect of delaying aging and enhancing physical fitness.
