1 Some elderly people will smear saliva on the bitten area after being bitten by mosquitoes. Does saliva really have the bactericidal effect equivalent to cool oil?

Saliva (saliva) does have a certain bactericidal effect. Saliva contains a component called lysozyme, which can directly dissolve bacteria in non-blood environment.

The ph value of saliva is about 6.6-7. 1, which is close to neutral and slightly acidic, so there should be no such thing as "neutralizing acid toxin".
