Too high water content can easily lead to mold, insect damage and decomposition of effective ingredients. Too low water content can affect the texture and crushing performance of the medicine or cause loss of effective ingredients. The water content is calculated by weighing the weight difference of the sample before and after drying. An appropriate amount of sample is accurately weighed, the sample is placed in an oven set at a certain temperature for drying until a constant weight is obtained, and the dried sample is removed and cooled to room temperature before being accurately weighed.
