Stephania tetrandra S. Moore (Hang Fang Ji) is used in traditional Chinese medicine as a diuretic, an antiphlogistic, and an antirheumatic. The name "fang ji" is applied to at least four different genera of plants, including Aristolochia fangchi Y. C. Wu ex L. D. Chow and S. M. Hwang, Cocculus orbiculatus (L.) DC., Stephania tetrandra S. Moore, and Sinomenium acutum Rehder and E. H. Wilson. Due to similarity in the use of their common names, Stephania tetrandra S. Moore is often confused with Aristolochia fangchi Y. C. Wu ex L. D. Chow and S. M. Hwang, which has potentially dangerous consequences. To aid rapid and easy differentiation between the roots of these four species, so as to avoid possible contamination, detailed macroscopic and microscopic observations were made using stereo-and light-microscopy. The powdered samples were further analyzed using HPLC.
防己（粉防己）在传统中药中用作利尿剂、抗炎药和抗风湿药。“防己”这个名称至少适用于四种不同属的植物，包括广防己（马兜铃科植物广防己）、木防己（防己科植物木防己）、粉防己（防己科植物粉防己）和青风藤（清风藤科植物青藤）。由于它们的常用名相似，粉防己常与广防己混淆，这可能会带来潜在的危险后果。为了有助于快速、轻松地区分这四种植物的根，以避免可能的污染，使用体视显微镜和光学显微镜进行了详细的宏观和微观观察。粉末样品进一步用高效液相色谱法进行分析。
