Some glutinous, sticky and easily-dissolved drugs, such as Ejiao (Colla Corii Asini), Lujiaojiao (Colla Cornus Cervi), Guibanjiao ( Colla Plastri restudinis ), maltose, honey and the like, should be dissolved by heating them separately so as to prevent them from sticking to the pot, burning or adhering to other drugs, and affecting their therapeutic effect. Before taken orally, they should be boiled together with the decoction from other drugs with mild fire or mixed when they are still hot.
