In this paper, classic preparations in Treatise on Febrile Diseases were systematically investigated to obtain their process parameters, and provide literature evidence and technical support for drug research and development. This paper includes the following sections: drug dose, solvents, excipients, and process parameters of classic preparations. The drug dose in Treatise on Febrile Diseases was not consistent with that in Pharmacopoeia of the People's Republic of China 2015, for example, "Yi-Liang" was about 15.625 g, and "Yi-Sheng" was about 200 mL. The solvents of classic preparations can be divided into two types: wine and water. There were eight kinds of water: water, "Dongliu water" "Ganlan water" "acid pulp" "Jinghua water" "Lao water" "Mafei Tang" "spring water". There four kinds of wines: "wine" "Bai wine" "Qing wine" "Ku wine". There were two kinds of excipients: rice and honey. Classic prescription powder had two kinds of processes: "whole prescription powder" and "Yidaoshai Hezhizhi powder". Classic prescription pills had three kinds of processes: direct whole prescription pilling, pilling after extraction, and pilling with excipients after smashing. Classic prescription decoction had six kinds of processes: "wine Tang", "Mafei Tang", "Jingmi Tang", "Mijian Tang", "water Tang" "Zhugao Tang". Drug dose, solvents, excipients, processes and other key parameters of classic preparations were systemically reviewed in this study, and the process parameters were clarified to provide literature evidence and technical support for drug development.
