- Abstract: As the smallest unit of traditional Chinese medicinal formula compatibility, herb-pair has the basic characteristic of traditional Chinese medicinal formula compatibility. In recent years, herb-pair investigation has attracted much attention, which is an indispensable part of modernization of traditional Chinese medicine. With the decrease of the efficiency in the discovery of new drug, how to discover new drugs from traditional Chinese medicinal herb-pair has also been a bottleneck for the research and development of drug. The authors reviewed the domestic and foreign literatures in the latest years and summarized the current situations and the existing problems of herb-pair study. Based on these investigations, the authors innovatively proposed a novel concept of "precision herb-pair". Difference from traditional Chinese medicinal herb-pair or formulae with extensive roles and unclear efficacies, "precision herb-pair" belongs to a developed new mini herb-pair formula with an exact treatment and a relatively clear composition based on a certain specific disease. In addition, the authors also proposed a new strategy of "herb-pair - screen of multiple constituents based on column separation and in vitro cell viability - fuzzy target recognition pharmacology - re-evaluation of precision herb-pair", and successfully applied it to the development of a precision herb-pair from Astragali Radix-Corni Fructus in treatment of diabetic nephropathy. This proposed new strategy is simple, easy to carry out, and has a wide application, and can offer references and thoughts for the modern investigation of herb-pair and the research and development of new drug.
