Chinese medical herbs have pharmaceutical actions of multi direction spectrum. By combination of herbs, these actions are increased or decreased. Chinese medical prescriptions are constructed by using this mechanism. In this paper, we discuss the action of Asarum heterotropoides by using Pattern analysis techniques. Eight Chinese medical prescriptions containing Asarum heterotropoides are classified into 3 groups, and these groups correspond to traditional pharmacological categories, which are “perspiration”, “expectoration” and “pain killing”. M-D-SCAL was found to be more adequate in this analysis than quantification of the fourth type.
Eight Chinese medical presriptions for bronchial asthma, listed in the official documents from the Japanese Ministry of Health & Welfare and 23 prescriptions for bronchial asthma, listed in Japanese “Kanpo” books, are analised using multidimentional scaling analysis and cluster analysis. As for the 8 officially listed prescriptions, a good configration was obtained with quadratic form. But their constructions were considered to be biased slightly to the attack period of bronchial ashtma. And the 23 other prescriptions were roughly classified to 6 groups. From the practical view of the padents who visit Chinese medical clinics, these 23 Prescriptions also have reasons for exlstence. The indications mentioned in the official publication should be reconsidered.
