Clinical application of classic formulae in treating dermatosis

The etiology and pathogenesis of dermatosis mainly include zang-fu disharmony,derangement of qi and blood,blockage of channel,exogenous pathogenic factors and so on in TCM.Conventional therapy based on pathogenesis may lead to the negligence of classic formulae in the textbook and clinic.The theory of formula corresponding to syndromes,which is based on clinical experience and classics,is a unique model contained in classics of TCM when we diagnose and treat diseases.Making symptoms and signs as the therapeutic targets,related formula is selected directly according to formula syndrome differentiation.Under the guidance of the principle of formulae corresponding to syndromes,we successfully treated chronic urticaria by bupleurum and cinnamon decoction,guizhi decoction and mahuang lianqiao chixiaodou decoction,cutaneous pruritus by maxing yi gan decoction.
