Please tell me what Chinese herbal pieces are? What are modern Chinese herbal pieces?

Simply put, the former is manual processing and the latter is mechanical processing.

The shape of traditional hand-processed decoction pieces varies according to the variety of medicinal materials (almost one kind is the same), which is not only convenient for distinguishing and identifying, but also convenient for frying in one can at the same time, so that the medicinal juice can be fully separated out (such as betel nut and white peony root, which are very hard, difficult to fry and can be fried), and the curative effect is guaranteed. However, mechanical processing can adjust the blade at most, and then cross-cut it with one knife. The processed decoction pieces can not be compared with traditional decoction pieces in identification, suffering and efficacy.

Chinese medicine is far less than that of Ming and Qing dynasties, which is also one of the reasons.
