Excessive moisture on the tongue surface, stretching the tongue and making it wet and slippery when touched is called slippery moss. Slippery moss is a manifestation of the internalization of water-dampness, the main phlegm-drinking (a pathological product formed by the impaired metabolism of water and liquid) and water-dampness. If cold and dampness invade, or Yang deficiency can not transport and transform water, cold and dampness, phlegm and drink.
Moss dense, fine particles, fusion into a piece, such as coated with greasy like, the middle of the thick side of the thin, close to the tongue, wipe not go, scraping not off, known as greasy moss.

The tongue body is larger and thicker than normal tongue, and the tongue is full of mouth, which is called fat tongue. Fatty tongue is seen in water-dampness internalization (water-dampness stays in the body), phlegm-dampness-heat-toxicity upward flooding.
The edge of the tongue body has traces of teeth pressure, known as tooth mark tongue, seen in the spleen deficiency, or water-dampness internalization evidence.
It is recommended that the patient seek medical treatment in time and be judged by a professional doctor.
