The tongue is enlarged. Generally, a slightly plump and tender tongue with a pale color and tooth marks on the edges often indicates spleen deficiency; if the tongue is deep red and swollen, filling the mouth, it suggests heat in the heart and spleen meridians, see the entry "swollen tongue"; if the tongue is swollen and enlarged, with a bluish-purple and dark color, it is often seen in cases of poisoning, see the entry "enlarged tongue".
