Physiology behind salivation before vomiting

Vomiting is a deliberate response by the body originally meant to be a mechanism to purge toxins or other foreign bodies from the stomach and esophagus. The problem is that stomach acid is highly acidic, and not too good to have anywhere in the body besides the stomach.
Therefore, without proper protection, vomiting can be harmful to the throat, mouth and teeth. That’s why we salivate before vomiting. It helps to dilute and rinse the acid as well as neutralize it due to its natural alkaline property. Of course when you’re repeatedly vomiting, this reflex sometimes fails to kick in so one feels weird sensation of taste and burning feel in tooth
