In this paper, based on the special influence of supramolecular chemistry on the basic theory of Chinese medicines ( CM) , the authors further analyzed the history of meridian tropism and natural origins of CM organisms and explained CM ingredients and the universal regularity of the automatic action of the supramolecular "imprinting templates" hole channel structure. After entering human bodies, CMs, as the aggregation of supramolecular "imprinting templates" , automatically seek supramolecular subjects that are matched with their "imprinting templates" in human meridians and organs for the purpose of self-recognition, self-organization, self-assembly and self-replication, so as to generate specific efficacy in meridians and organs, which is reflected as the meridian tropism phenomena at macro level. This regularity can be studied by in vitro and in vivo experimental studies. In vitro methods are mostly supra molecular structure analysis and kinetic and thermodynamic parameter calculation; Whereas in vivo methods are dominated by the analysis on object component distribution, chromatopharmacodynamic parameters and network chromatopharmacodynamic parameters; Particularly, the acupoint-medicine method can simplify to study the supramolecular subject-object relations. Consequently, CM's'meridian tropism reveals the universal regularity for interactions of macromolecular and micromolecular "imprinting templates" of subjects and objects in natural organisms. As the first barrier for the material base of the CM theory and breakthrough in the modernization of the basic CM theory, meridian tropism plays an important role in studies on basic theories of the basic CM theory.

The paper, based on the previous publication as special impact of Chinese medicine theories on supramolcular chemistry, aims to analyze the natural origination for the Chinese medicine and to explain the special impact of "Qi chromatography" reaction on "imprinting templates" in supramolcular host of human being with Chinese medicine, in order to reveal the CM's properties of "medical element" with "imprinting templates" autonomisation generally took place in natural supramolecules, and also to discover that the CM's pharmacology are satisfied with its own approaches different form western pharmacology. It was decided, for CM's pharmacology guided by CM's theories, to "Qi chromatography" relations between the CM's ingredient groups and the meridian zang-fu viscera. The supramolcular chemistry played an all-through role in procession of making macro-regularities and special presentation on behavior of "Qi chromatography" impulse owning to the matching action of all kinds of ingredients on the meridian zang-fu viscera with similar "imprinting templates". The CM's pharmacology were guided by CM's theories, owing to its interpretation of supramolecular chemistry. The pharmacology was achieved to construct up completely on base of classical chemical single molecular bonds whereas the CM's pharmacology be configured to big building by way of "imprinting templates" as multi-weak bonds among "supramolecular society". CM's pharmacology was supramolcular pharmacology dealt with "molecular society" on the base of western pharmacology, and employed to double research approaches both math-physical quantitative representation on macroscope and qualitative analyses in microscope.

The paper aimed to elucidate the specific impact of supramolecular chemistry on the Chinese medicine theories (CMT) in their modernization, after had summarized up the research status of supramolecular chemistry and analyzed the possible supramolecular forms of Chinese medicine (CM), as well as considered the problems in modernization of CM theories. On comparison of the classical chemistry that delt with chemical bonds among atoms, the supramolecular chemistry was rather concerned with varietes of weak noncovalent bonds intermolecules, and reflected the macro-apparent chemical properties of each molecules, and was the most appropriate chemical theories to explain the CMT and microcosmic materials. The molecules in the human body and Chinese material medica (CMM) formed supramolecules by way of self-assembly, self-organization, self-recognition and self-replication, with themselves or with complexation, composition, chelation, inclusion, neutralization etc. Meridian and Zang-fu viscera in CMT might be a space channel structure continuously consisted of unique molecules cavity that was imprinted with the supramolecularly template inside and outside of cells, through which the molecules in CMM interacted with the meridian and Zang-fu viscera. When small molecules in human body imprinted with macromolecules in meridian and Zang-fu viscera, in other words, they migrated along within imprinting channels of meridian and Zang-fu viscera on behavior of "Qi chromatography" impulsed by the heart beat, finally showed up on macroscopic the anisotropy of tissue and organ, as described namely as visceral manifestation in Chinese medical science. When small molecules in CMM interacted with imprinting channel on meridian and Zang-fu viscera, the natural properties and efficacy regularities of CMM was reflected on macroscopic. Therefore, the special representation forms of basic CMT is based on the macroscopic expression of "Qi chromatography" abided by imprinting effect regularities, and on whether the imprinted template of small molecules matched with cavity template of macromolecules in meridian and Zang-fu viscera, only is the adequate representation of supramolecular chemistry for them. The CMM materials is the mixture including single molecules and supramolecules. The compatibility for CM prescriptions can significantly change the function rules. Therefore in the study of basic CMT, we should pay special attention to the laws of supramolecular chemistry. It is the most essential differences of the CMT from the modern medicine which established by the laws of single molecular theories.
