According to the different disease processes involved, tidal fevers fall into various clinical types, i.e. those that may be treated by purging, those that should not be treated by purging and the pernicious type (ezheng). Tidal fevers susceptible to purging include those treated with Drastic Purgative Decoction (da chengqi tang), Mild Purgative Decoction (xiao chengqi tang), da xianxiao decoction and Major Bupleurum Decoction (da chaihu tang). Tidal fevers not susceptible to purging include those treated with Cassia Twig Decoction (guizhi tang), Minor Bupleurum and Poria Decoction (xiao chaihu fuling tang), Minor Bupleurum Decoction (xiao chaihu tang), and Decoction of Ephedra, Weeping Forsythia Fruit and Red Beans (mahuang lianqiao chi xiao dou tang). The pernicious variety (ezheng) refers to cases where, five or six days after the onset of cold damage, the condition has not been relieved by purgative techniques involving sweating and emesis, the tidal fever recurs in the morning and late afternoon, and the patient looks like someone who has seen a ghost.
