AN IMPROVED MATHEMATIC MODEL OF RELATIVE DOSAGE OF HERB FOR CHINESE MEDICINE PRESCRIPTION GAO QUANQUAN* and REN TINGGE

The intelligent analysis and mining system of curative efficacy messages of Chinese Medicine (CM) prescription is based on CM theory, which can realize description of mathematical measuring and qualitative forecast analysis of CM recipes by applying information processing and intelligent reasoning technology. In this system, the mathematic model of relative dosage of any herb is an important foundation for further calculations and reasoning. In this paper, we introduce a new concept named “dosage intensity” to replace the old one “relative dosage”. In addition, a non-linear model of “dosage intensity” is presented and discussed. We have used this new model to calculate all of 561 common herbs and 27 recipes in “Shanghan Lun” and other documents to verify its validity. The advantages of this model are obviously displayed during curative efficacy mining of CM prescription.
