Understanding of genuine Medicinal Materials Fang Zheng and Analysis of planting varieties in 2019：

Chinese medicine has always emphasized the concept of "authentic medicinal materials".?Li Shizhen also said in the Compendium of Materia Medica that "animals and plants are born because of the wrong nature of the land.".?Apart from its native land, it has the same quality but different effect. "?In "Qianjin Yi Fang", Sun Simiao put special emphasis on the origin of medicinal materials, pointing out that "the use of drugs must be based on the land", which may lay the foundation for the formal use of the term "genuine medicinal materials" in later generations.

In essence, "genuine" and "non-genuine" are regional signs with differences in medicinal value from plants, because they are one of the important factors affecting the clinical efficacy and safety of traditional Chinese medicine.?Therefore, "genuine medicinal materials" is of great significance to ensure the quality of medicinal materials is stable, controllable, safe and effective for clinical use.

In order to develop the cultivation of traditional Chinese medicine in Liaoning, we must abide by the principle of authenticity, and select planting varieties according to the unique soil in Liaoning and the climatic characteristics of drought and little rain in successive years. Liaoning Fangzheng Agricultural Science and Technology Development Co., Ltd., through with Shenyang Agricultural University,The common practice and exploration of many agricultural scientific research institutions such as Liaoning University of traditional Chinese Medicine have sorted out the latest interplanting techniques for the cultivation of genuine medicinal materials in Liaoning Province, optimizing seedling, ecological planting and efficient management, so as to realize the safety and high yield of traditional Chinese medicine planting.
