The appearance of greenish-black spots on the tongue is called ecchymosis.

The term "tongue ecchymosis" has not been found in ancient medical literature and only began to appear in recent publications. Generally, the condition of tongue ecchymosis was already included in the discussion of "青 purple tongue" in ancient times. However, strictly speaking, tongue ecchymosis is darker than "青 purple tongue," with a slight blackish tint; small, dot-like spots are called petechiae, and several petechiae merging together form ecchymosis. Additionally, "青 purple tongue" is associated with a wider range of illnesses, while tongue ecchymosis is primarily linked to static blood. Therefore, it is necessary to dedicate a separate section to discuss this condition.
