What are the traditional Chinese medicine treatments for allergic urticaria?

The treatment of allergic urticaria in traditional Chinese medicine (TCM) mainly includes syndrome differentiation-based therapy and external treatments. In terms of syndrome differentiation, according to different syndrome types of urticaria, such as wind-cold type, wind-heat type, and damp-heat in the gastrointestinal type, corresponding TCM prescriptions are used, such as Ephedra Decoction (Ma Huang Tang) with modifications, Honeysuckle & Forsythia Powder (Yin Qiao San) with modifications, and Fangfeng Tongsheng Pills. For external treatment, herbs such as Portulaca, Coptis, and Phellodendron are commonly decocted in water and applied as cold wet compresses to relieve itching. In addition, TCM often combines therapies such as acupuncture, pricking blood vessels, cupping, and the use of patent medicines like Yupingfeng Capsules or Granules to enhance therapeutic effects. The specific treatment plan should be determined according to the patient's individual condition and the physician's recommendations.
