Is it safe to drink saliva?

Drinking saliva is generally safe, as it is a natural bodily fluid that contains enzymes and proteins beneficial for digestion and oral health. However, it can carry bacteria and viruses, especially if a person is ill or has poor oral hygiene. In most cases, the body’s immune system can handle these microorganisms, but it’s advisable to avoid ingesting saliva if there are concerns about infections or hygiene.
