Atractylodes macrocephala is a dried root of Atractylodes macrocephala, which has the functions of strengthening spleen and Qi, moistening water, preventing sweating, and preventing fetalization. The 2000 edition of the Pharmacopoeia’s cutting method for Atractylodes macrocephala was “removing impurities, washing, moistening, cutting thick slices, and drying”, and elaborated in the “National Chinese Medicine Processing Standard” to specify the water treatment before cutting Atractylodes macrocephala. It takes about 2-4 hours to “soak it up to three or four percent, remove it, saturate it until it becomes clear”, and it takes about 2-4 hours, and the active ingredients (such as vitamin A and atractylone) of Atractylodes macrocephala are lost during the soaking process. It will have an adverse effect on the curative effect; the cut pieces are irregular thick slices. In our district, the steam method was used. After heating at a high temperature, the dryness was eased and the strength increased.
