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
