There is a method of keeping in good health handed down from ancient times to the present, that is, using the "great doctor" of the human body to keep in good health, which is actually our own saliva.
Whether saliva is abnormal depends first on whether it is available, and second on whether it can be secreted in good quality and quantity. What does saliva have to do with? It is related to the kidney, and the kidney is actually related to the ren meridian-so the secretion ability and level of the salivary gland itself are directly related to the ren meridian.
What does saliva have to do with? It's related to the kidney. I treated a drug addict before. After giving him acupuncture, he said that he had no saliva after taking drugs, but now he feels saliva after using acupuncture. Why? Because drugs blocked his pulse, he passed acupuncture again. After ren mai tong, human saliva will be secreted normally.
The way for ordinary people to promote saliva secretion is to lick the upper jaw with their tongue. As soon as your tongue sticks up, saliva comes out, and then your mouth is full of saliva and you swallow it. This is a Taoist practice method, which can be practiced at any time, even when sleeping.
Also pay attention to keep your saliva clean, and then don't drink a lot of water if you have nothing to do. This requirement seems a bit high, but if a person has enough kidney essence and saliva, he doesn't need to drink a lot of water. Why do some people always eat with relish? How can they "relish" without saliva? How can they "relish" without saliva? How can they have so much to say? Why don't I advocate drinking more water when people are free? Because drinking water will dilute saliva and gastric juice and reduce our digestive function.
By the same token, I don't agree to eat soup and soak rice. Why don't I advocate drinking more water when people are free? Because drinking water will dilute saliva and gastric juice and reduce our digestive function. Many people have little or no saliva secretion, so the quality of saliva will be very low after drinking a mouthful of water and eating a mouthful of rice.
People suffering from Sjogren's syndrome are particularly pitiful, because their salivary glands lose activity, their teeth lose moisture and protection, they are easy to break, and then small pieces fall off, leaving only the residual roots of their teeth.
