Fire processing

火制 〔火製〕 huǒ zhì

Processing medicinals by the application of heat. Fire processing methods involve either direct or indirect contact of the materials with a heat source, sometimes with adjuvants. Care is required in controlling time and temperature, and the quantity of any additive used; excessively high temperatures can cause undesirable changes in a medicinal’s characteristics. The most common forms of fire processing are the various forms of stir-frying and mix-frying. Less commonly used methods are roasting and stone-baking.
