Melena refers to the passage of black, sticky stools, which often indicates the presence of digested blood in the gastrointestinal tract. This condition is a significant symptom in both conventional medicine and Traditional Chinese Medicine (TCM), pointing towards potential internal bleeding or other serious digestive system issues. The black and tarry appearance of the stool is a result of blood that has been digested as it passes through the intestines, transforming its color and consistency.
In Traditional Chinese Medicine, melena is seen through a holistic lens, indicating an underlying disharmony within the body's energy pathways or organs. TCM posits that this symptom can arise from various patterns of imbalance, such as Qi Stagnation or Heat in the Blood.
Recognizing the specific pattern behind melena is critical for TCM practitioners, as it guides the selection of treatments aimed at restoring balance and addressing the root cause of the symptom.
TCM Patterns for Melena Black Tarry Stool
Each pattern represents a distinct underlying imbalance that can cause melena black tarry stool
Qi And Blood Stagnation
Diagnostic signs
Choppy (Se), Wiry (Xian)
The tongue body is characteristically dark purple or has an uneven dusky hue. Stasis spots (purple-blue dots or patches) may be scattered across the tongue surface, particularly along the edges. The sublingual veins are often the most telling feature: they appear distended, tortuous, and dark purple or even blue-black in colour. When Blood stasis is more advanced, these veins may branch into a web-like pattern. The coating is typically thin and white, though if the stagnation has begun generating Heat over time, a slight yellow tinge may appear. In cases where Qi stagnation predominates early on, the tongue may only appear slightly dark red rather than fully purple, progressing to deeper purple as Blood stasis worsens.

Heat in the Blood
Diagnostic signs
Rapid (Shu), Wiry (Xian), Slippery (Hua)
The tongue in Heat in the Blood is red to deep red (crimson), reflecting the intensity of Heat in the blood. In moderate presentations, the tongue is red with red spots or prickles, especially on the tip (corresponding to the Heart). The coating is typically thin and yellow, and the tongue surface tends to be dry due to Heat consuming fluids. In more severe presentations, the tongue may approach a crimson or deep red colour, but this indicates progression toward a more serious stage. The sides may also be redder than normal, reflecting Liver involvement. The tongue body often looks older and tougher in texture rather than tender.
