In Traditional Chinese Medicine (TCM), urticaria is often considered to be related to the invasion of "wind evil" or imbalance of Qi and blood in the body, and is usually improved by regulating the constitution and dispelling wind to relieve itching. It is recommended to combine TCM diagnosis with internal and external treatments to alleviate symptoms.

Specifically, this can be understood from the following aspects:

1. **Diverse Etiology:** Traditional Chinese medicine believes that the onset of the disease may be related to external wind-heat or wind-cold, or it may be caused by improper diet, emotional stress leading to internal damp-heat or blood deficiency, thereby triggering itchy rashes on the skin.
2. **Treatment based on type**: Common types such as wind-heat type require dispelling wind and clearing heat, wind-cold type requires dispelling cold and wind, while blood deficiency and wind-dryness type focuses on nourishing blood and moisturizing dryness. The appropriate method should be selected according to the individual's condition.
3. **Common Treatment Methods:** These include oral Chinese medicine, external washes, and auxiliary therapies such as acupuncture and cupping, all aimed at balancing Qi and blood and eliminating pathogenic factors.
In daily life, avoid spicy and irritating foods, maintain emotional stability, and wear loose cotton clothing to reduce friction. If symptoms recur frequently, it is recommended to consult a professional Traditional Chinese Medicine practitioner for personalized treatment to gradually improve your constitution.
