What's the difference between Chinese herbal medicine pieces production enterprises and Chinese herbal medicine pieces processing enterprises?

The production of Chinese herbal pieces is to purchase and produce Chinese herbal pieces by ourselves, and the processing of Chinese herbal pieces is to entrust the factory to process the medicinal materials provided by others.

Chinese herbal pieces are processed according to the theory and processing method of traditional Chinese medicine, which can be directly used in clinical Chinese medicine. This concept shows that there is no absolute boundary between Chinese herbal medicines and Chinese herbal pieces. Chinese herbal pieces include some Chinese herbal pieces (including cut pieces, blocks and petals) processed in the place of origin, original Chinese herbal pieces and cut (baked on the basis of processing in the place of origin) pieces. The first two categories should be regarded as Chinese herbal medicines in management, and they are only understood as decoction pieces according to the theory of traditional Chinese medicine in formulation and preparation. The concept of decoction pieces in the sense of management should be understood as: "According to the needs of preparations or preparations, the finished products made by further cutting and baking pure medicinal materials processed in the place of origin are called decoction pieces of traditional Chinese medicine."
