White Tiger Decoction,White Tiger Decoction Plus Ginseng,Lophatherum and Gypsum Decoction,and Frigid Extremities De-coction Plus Ginseng all have sweating and fever as their symptoms.The fundamental difference in the pathogenesis of these four syn-dromes lies in the presence or absence of interior heat,the excess or deficiency of fluids and yang qi.The pathogenesis of White Tiger Decoction syndrome is excessive interior heat and slight loss of fluids,with the body usually not showing signs of shock.The pathogene-sis of White Tiger Decoction Plus Ginseng syndrome is excessive heat and severe deficiency of fluids,with the body often showing pre-liminary signs of hypovolemic shock.The pathogenesis of Lophatherum and Gypsum Decoction syndrome is excessive heat remaining un-resolved and injury to both qi and body fluids,with the body often being in a state of near recovery.The pathogenesis of Frigid Extremi-ties Decoction Plus Ginseng syndrome is deficient qi following blood loss,with both yin and yang deficiency,and the body often being in a state of shock.The differences in drug use among the four formulas lie in the proportion of emphasis on clearing heat,supplementing and restoring yang.The whole White Tiger Decoction is dominated by cold and cooling drugs,with the overall function of clearing interi-or heat.The whole White Tiger Decoction Plus Ginseng shows a balance of clearing heat and supplementing.Lophatherum and Gypsum Decoction mainly focuses on supplementing qi and tonifying the body fluids,with clearing heat as a secondary function.Frigid Extremi-ties Decoction Plus Ginseng mainly focuses on restoring yang from collapse,with tonifying qi and replenishing fluids as a secondary function.In clinical practice,both the differentiation of pathogenesis and the dynamic changes of the condition should be taken into con-sideration when these four formulas are used.
