First, what is Chinese medicine? Before answering this question, let's define or explain "traditional Chinese medicine": the general name of drugs used to prevent and treat diseases under the guidance of drug theory. Including pills, powders, ointments, pills, decoction, decoction pieces and other traditional dosage forms; Now there are some new dosage forms such as tablets, injections and sprays. No matter in the past or in modern times, the most traditional dosage form of "Chinese medicine" is "Chinese herbal pieces", which is called "Chinese herbal pieces", commonly known as "decoction medicine" and "great doctor". A more vivid description is the so-called "old" or "old" prescription, which is wrapped in paper and taken home to cook into soup. Some people call it "Chinese herbal medicine". Give a scientific and standardized definition of "Chinese herbal pieces". Chinese herbal pieces refer to the finished products that are specially processed under the guidance of medical theory and according to the needs of syndrome differentiation and preparation. Clinically, the drugs used to treat diseases are Chinese herbal pieces and Chinese patent medicines, and the raw materials of Chinese patent medicines are also Chinese herbal pieces, not Chinese herbal medicines. Some people confuse Chinese herbal medicines with Chinese herbal pieces. There are indeed some varieties of Chinese herbal pieces and Chinese herbal medicines that are not very different, or have the same or similar appearance, but they are essentially different. This difference is like boiled eggs and raw eggs, which are similar in appearance but different in essence. However, there are also some individuals who are completely consistent. For example, there is no such difference between Chinese herbal medicines and Chinese herbal medicines, but "Chinese herbal medicines" are mostly processed and have qualitative differences. So Chinese herbal medicine can't be called Chinese herbal medicine, but it can be used to explain what Chinese herbal medicine is.
