[Objective] To observe the therapeutic effect of wind-dispersing and cold-dispelling, blood-activating and stasis-removing therapy for cold-type urticaria and to explore its possible mechamism. [Methods] Sixty-six cases were allocated to two groups by a simple random sampling method. Group A ( n = 36) was treated with wind-dispersing and cold-dispelling, blood-activating and stasis-removing herbal medicine including Herba Ephedrae, Ramulus Cinnamomi, Herba Schizonepetae, Radix Saposhnikoviae, Semen Armeniacae Amarum, Rhizoma Zingiberis Recens, Fructus Jujubae, Radix Salviae Miltiorrhizae, Radix Angelicae Sinensis, Caulis Spatholobi, Radix Paeoniae Rubra, etc. Group B (n =30) was treated with cetirizine hydrochloride tablets. The two groups were treated for two 20-day courses. One week after treatment, the therapeutic effect and the changes of hemorheological parameters before and after treatment were observed and compared with those in 38 healthy volunteers. [Results] The total effective rate was 80.6% in group A and 63.3% in group B, the difference being significant ( P 0.05) . [ Conclusion] Wind-dispersing and cold-dispelling, blood-activating and stasis-removing therapy is an important method for cold-type urticaria and the selected herbal medicines are effective. Its therapeutic mechanism may be related to the improvement of hemorheological parameters.
