Drool

One of the five humors; associated with the spleen. Drool together with spittle, the humor of the kidney, forms drool-spittle or spittle humor, which keep the mouth moist and help digestion. Drool is said to spring from the cheeks, and to flow out from the corners of the mouth during sleep. Spittle is said to spring from under the tongue, and to be spat out of the mouth. When the spleen and stomach are normal, there is ample liquid; there is harmony of mouth, there is no dryness of mouth or thirst, and food is flavorsome. In spleen-stomach vacuity cold, cold drool wells upward and there is a bland taste in the mouth and nausea. In intense stomach fire, drool is scant and the mouth is dry. Spleen-stomach damp-heat or worm accumulations, wind stroke, or epilepsy can cause drooling or foaming at the corners of the mouth. Compare phlegm-drool.
