In traditional Chinese medicine, what is the term for the examination of the tongue?

In traditional Chinese medicine, the examination of the tongue is specifically referred to as glossoscopy. This process involves assessing various characteristics of the tongue such as its color, shape, coating, and texture, which can provide valuable insights into the patient's internal health and balance of yin and yang. The tongue is viewed as a "map" of the body, reflecting the state of different organ systems and potential health issues.

Glossoscopy is a critical aspect of diagnosis in traditional Chinese medicine alongside other methods like pulse diagnosis. Each component of the tongue's appearance can indicate different health conditions, allowing practitioners to make informed decisions about treatment and care.
