The result proved that the main body of research of traditional Chinese medicine is researchers who possessed the fundamentals of traditional Chinese medicine. It is the objects of research of traditional Chinese medicine that origin of a class of traditional Chinese medical literature consisting of herbals which focus on descriptions of individual drugs; the relationship of the technological process of preparing Chinese medicine, as by parching, roasting, baking, steaming, soaking, and simmering, etc.;and technology of separating, extracting and purifying for composition; traditional Chinese medicine dynamics of one of the 12 two-hour periods into which the day was formerly divided before the introduction of western chronology; compatibility of medicines in active compositions; patent, effectiveness for a given period of time and constantly changing of traditional Chinese medicine.The relationship between the main body and the objects was that the former depends on the latter ones and the main body has subjective initiative as fully as possible.展开更多
