Saliva does not have a clear disinfection effect, you can not use saliva instead of disinfectant to disinfect wounds and objects, although some research data show that saliva contains lysozyme type and other antibacterial substances, but mainly for common oral bacteria, for other pathogens usually have no killing effect, and the concentration is very low, and it is not possible to effectively kill viruses and bacteria, so rely on saliva sterilization anti-inflammatory is not reliable. In addition, the human mouth may also contain other pathogens, the antibacterial substances in saliva can only kill a certain type of bacteria in the mouth, while other pathogens that may cause disease still survive, such as herpes virus, etc. If saliva is used for wound disinfection, there is a possibility that the pathogens will be brought to the wound, causing wound infection. So all in all, using saliva for sterilization and anti-inflammation is not only unable to achieve the desired effect, but also has potential health risks. So with a wound must be formal disinfection treatment, such as the application of iodine, hydrogen peroxide, alcohol and other disinfectant solutions with strong bactericidal and disinfection effects.
