An ulcer is a break in the skin or mucous membrane with loss of surface tissue, disintegration, and necrosis of epithelial tissue. Ulcers can manifest anywhere on the body but are most commonly found in the digestive tract, skin, and lower extremities. They can range from minor, easily healed sores to severe, deep-rooted wounds that may require significant medical intervention. Sub-symptoms of ulcers include chronic ulcers, which persist over time, deep-rooted ulcers that penetrate deeply into skin layers, and bedsores, often a result of prolonged pressure on the skin.
Traditional Chinese Medicine (TCM) perceives ulcers through a distinct lens, emphasizing the imbalance of Qi (vital energy), Blood, and Body Fluids. Contrary to Western medicine's focus on local infection and inflammation, TCM identifies ulcers as manifestations of underlying disharmonies within the body's internal landscape.
It highlights the importance of diagnosing the specific pattern of imbalance, whether it be Qi Deficiency, Blood Stagnation, Damp-Heat accumulation, or Yin Deficiency. Recognizing and addressing these patterns is fundamental to effectively treating ulcers and restoring the body's natural harmony and health.
TCM Patterns for Ulcer
Each pattern represents a distinct underlying imbalance that can cause ulcer
Spleen Qi Deficiency
Diagnostic signs
Empty (Xu), Slowed-down (Huan), Weak (Ruo)
The tongue is typically pale and may appear slightly puffy or tender (soft in texture), often with tooth marks along the edges where the swollen tongue presses against the teeth. The coating is thin and white. The tongue body generally retains normal moisture. In some cases, a faintly greasy coating may appear over the centre and root, hinting at early Dampness accumulation as a secondary development, but in the core pattern the coating remains thin and white without significant greasiness.
Lung Qi Deficiency
Diagnostic signs
Empty (Xu), Weak (Ruo)
The tongue body is characteristically pale, reflecting the underlying Qi deficiency and its inability to push Blood upward to nourish the tongue. It may appear slightly puffy or soft-textured (what TCM calls 'tender'), and teeth marks along the edges are common because the weakened Qi fails to hold tissues firm. The coating is typically thin and white, which is consistent with a Cold-deficiency pattern rather than Heat. In straightforward Lung Qi Deficiency the tongue is not dry, though if the pattern starts to involve Yin deficiency (a more advanced stage), some dryness may appear.
Qi and Blood Deficiency
Diagnostic signs
Fine (Xi), Weak (Ruo), Empty (Xu), Slowed-down (Huan)
The tongue body is characteristically pale, reflecting both Qi and Blood insufficiency. It may be slightly thin due to Blood failing to fill the tongue body, or it may show teeth marks on the edges if the Spleen Qi component is pronounced, causing the tongue to become slightly swollen and soft against the teeth. The coating is thin and white, which is consistent with a deficiency pattern without Heat or Dampness involvement. In more chronic cases, the tongue may appear slightly dry if Blood deficiency is more severe, but this is not a primary feature of the base pattern. The undersurface veins should appear normal and not distended.
