In other words, if I want to create extra saliva to appease a dry throat or swallow a pill without water, i can just summon extra saliva. How??

I’m usually able to increase saliva production significantly by biting (not too hard) the very top if my tongue.
The nerves that control saliva production are part of a reflex system. They fire without conscious thought and can be activated by smells, tastes and even the movement of jaw muscles!
