[Strategy for research on quality identification and ecological environment-related of Dao-di herb]

For a long time, due to the shortage of a objective and clear method and standard for the quality evaluation of the Dao-di herb, it is difficult to distinguish the Dao-di herb. Geo-herbalism and environment-related studies often fall into the vicious circle of "have target but no indicators" and "circular reasoning" because of lack of objective and a clear indication of the quality characteristics. So it is difficult to reveal the ecological environment factors that form the quality of Dao-di herb. The research team put forward innovative idea that taking the medicine quality evaluation method and authentic standard as a breakthrough, starting from the effect, evaluating quality by effect, evaluating the environment by the drug quality, and establishing the thinking and pattern of identify authentic Chinese herbs (quality ecological studies of the Dao-di herb) based on the research path of "effect-quality-environment". The authors hope that they can provide theoretical and technical support to reveal the dominant factors of the ecological environment that impact of the quality of the Dao-di herb, build the Dao-di herb clinical application of dose conversion mechanism, clarify the connotations of the modern science of the Dao-di herb and solve the key issues that constraint the development of the Dao-di herb production and clinical application of it.
