Good things to increase saliva flow?

[Eric]

Lately I've been very meticulous with my oral hygiene (brushing/flossing 3x/day, etc...) and have seen a great reduction in white coating on tongue. My breath is still the same.

I think my problem may lie in my gums or the fact that the back of my throat/nose are always very dry. Does anybody know of good products/naturals that can increase my saliva production?

As I type this I have this strange nasty taste somewhere in my upper throat area. I think I developed unusual throat architecture that causes food to get trapped in my upper throat area between my mouth and nose. Lately I've had to 'hock loogies' directly after eating to clear this space of food debris. Feels like I'm getting most of it, but I bet there's just enough left to breakdown and cause shit smell.
