At the same time, do something for its protection. Textual research from forme herbal medicine bookmaking of Coptis. Study the resource of Coptis Salisb. in Anhui province. Made pharmacognosy research of Coptis chinensis var. brevisepala.Also on artificial cultivation of it.Methods:Refer to the Ben cao jing ji zhu (Variorum of Classsic Of Materia Medica) to Ben cao gang mu shi yi (Supplement to the Compendium of Materia Medica), which cover 1200 years of ancient herbal works. Combining the geographical administrative division of ancient records to textual research. Then discussion and analysis of past dynasties medicinal Coptis use complexion.
