Tongue is an important organ in the human body mainly known as an organ of speech and taste. It is also used as a diagnostic tool in ancient medicine. In Ayurveda, Jivha Parikshan (Tongue examination) is one of the important parameters considered by the physician for the diagnosis of any disease. Similarly in Chinese and Korean medicine also tongue based diagnosis has been prevalent since ancient times. Various features of the tongue are considered for detection of diseases. Features such as tongue color, texture, geometry, coating, teeth marks, etc are mainly examined. Amongst these features the texture of the tongue plays a key role in detecting the disease and correlating with the symptoms seen.
