The tongue is the organ of taste and speech. Size, shape,
contour, surface, margins, and color are the characteristics one can observe on the
tongue. A pale tongue may indicate an anemic condition or lack of blood in the body. An
yellowish tongue may suggest that excess bile present in the gallbladder or a possible
liver disorder. A blue tongue is normally an indication of problems with the heart.
Different areas of the tongue corresponds to different
organs of the body. Hence by correlating the location of the blemishes on the tongue, the
Ayurvedic practitioner can determine which organs of the body are out of balance.
A whitish tongue indicates Kapha imbalance and mucus
accumulation. A red or yellow green tongue indicated a Pitta imbalance. A vata imbalance
is manifested by a black to brown coloration on the tongue.
If the tongue is covered by a coating, it may indicate the
presence of toxins in the stomach, small intestine or large intestine. If the posterior
part of the tongue is coated, it will indicate that toxins are present in the large
intestine. If the middle of the tongue is coated, the toxins are present in the stomach
and in the small intestine.
