As we all know, the first sight is description when we read drug instruction. The original meaning of description in Chinese is “叙述”、“描写”, however, in the aspect of drug, it means “性状”. Its main contents are introducing appearance, chemical and physical property, structure etc. Sometimes, there are some other names instead of description, such as chemical structure, composition, physical and chemical properties etc.
