What Does Tongue Reveal in Your Health?

Tongue diagnosis is an important part of Eastern Medicine.  The tongue is unique in being an internal organ that can be exposed without surgical incision.  Just like the eyes, which are developed from an out-pouching of the central nervous system during embryonic development and thus associated with them, the tongue is connected with many organ systems.  Changes of tongue body and its color, coating, shape, movement and moisture level can reflect subtle changes from internal organs. 

Chinese have developed a sophisticated system to evaluate such changes to help diagnose functional disorders of the body, as well as determine their severity.  Learning about appearance changes of the tongue can help gain insight into your health to seek medical attention at early stages of diseases and formulate healthy diet to promote healthy living.

Below is a tongue diagram that illustrates areas of tongue in association with various organ systems.
