Condition Categories
Urticaria, commonly known as hives, is a skin condition characterized by red, itchy, raised welts that appear on the surface of the skin. These welts can vary in size and shape and can occur anywhere on the body. Urticaria can be triggered by various factors, including allergic reactions, stress, infections, or even exposure to cold or heat. Chronic urticaria, a form where symptoms persist for more than six weeks, poses a significant challenge to patients' quality of life, often requiring a deeper investigation into underlying causes.
Traditional Chinese Medicine (TCM) views urticaria as a result of external pathogenic factors invading the body, leading to an imbalance between the body's defensive energy (Wei Qi) and the pathogenic factor. TCM categorizes urticaria based on underlying patterns of disharmony, such as Wind-Heat, or Blood Deficiency, each presenting with distinct symptoms.
Identifying the correct pattern is crucial in TCM, as it guides the treatment strategy to not only alleviate the symptoms but also address the root cause of the imbalance, aiming for long-term relief and balance restoration.
TCM Patterns for Urticaria
Each pattern represents a distinct underlying imbalance that can cause urticaria
Blood Deficiency with External Wind
Diagnostic signs
Fine (Xi), Floating (Fu), Wiry (Xian)
The tongue body is typically pale and may appear slightly thin or small, reflecting the underlying Blood Deficiency. The coating is thin and white, which is consistent with an external pathogenic factor (Wind) that has not yet generated Heat. The tongue may appear slightly dry, especially at the edges, due to Blood's failure to moisten. If the condition is longstanding, slight peeling may begin to develop in patches, but a fully geographic tongue would suggest progression toward Yin Deficiency.

Heat and Blood Stagnation in the Lower Burner
Diagnostic signs
Choppy (Se), Full (Shi), Deep (Chen), Rapid (Shu)
The tongue is typically reddish-purple, reflecting the combination of Heat (redness) and Blood Stasis (purple hue). Stasis spots or ecchymoses may be visible on the tongue body, particularly towards the root, which corresponds to the lower body. The sublingual veins are often distended, dark, and tortuous, which is one of the most reliable signs of Blood Stasis. The coating tends to be yellow and dry, reflecting interior Heat consuming fluids. In severe or prolonged cases, the tongue surface may appear dry with prickles, indicating intense Heat scorching the Blood.
Exterior Cold invading the Interior
Diagnostic signs
Deep (Chen), Slow (Chi), Tight (Jin)
The tongue is characteristically pale and swollen, reflecting the Cold congealing Yang and impairing fluid metabolism. The coating is white, moist, and slippery, indicating Cold and accumulated fluids in the interior. Teeth marks along the edges suggest the Spleen Yang is struggling to transport and transform fluids, leading to a puffy tongue body. There is no redness, dryness, or yellow coating, which would suggest Heat. In more severe cases the tongue may take on a slightly bluish tint, particularly at the root, reflecting deeper Cold penetration.
Oedema
Diagnostic signs
Hidden (Fu), Slowed-down (Huan)
Kidney Yang Deficiency
Diagnostic signs
Deep (Chen), Slow (Chi), Weak (Ruo)
The tongue in Kidney Yang Deficiency is characteristically pale and puffy, often with a soft, tender quality and visible indentations from the teeth along its edges. The surface tends to be wet or slippery, reflecting the body's inability to properly transform and move fluids. The coating is white and may appear moist or slippery. In more severe cases, the tongue can become quite swollen and waterlogged in appearance. The root of the tongue (corresponding to the Kidney area) may appear particularly pale or enlarged.
