Tongue Diagnostics: The Hidden Code that Speaks about Your Body

Abstract

The tongue is an important organ of the oral cavity, playing a role in digestion, speech formation, and taste perception. Changes in its color and structure reflect the internal environment of the body and have diagnostic significance. Tongue diagnostics has been widely used in ancient medical practices, and modern research also confirms its role in the early detection of various diseases. According to traditional Chinese medicine, the tongue reflects the condition of different internal organs and serves as an important tool in diagnosis. Studies have found that changes in the tongue’s color, coating, and structure are linked to the function of internal organs, metabolic disorders, and systemic diseases. This article examines the theoretical foundations of tongue diagnostics, its clinical significance, and its role in both modern and traditional medicine.
