Yunnan Baiyao is a traditional Chinese herbal medicine that has been used to treat wounds for over 100 years. Here, we use Atomic Force Microscopy (AFM) to determine nano-scale structures of the Yunnan Baiyao. AFM images revealed uniform nanofibers present in relatively high abundance in a solution of this medicine. Fibers were typically 25.1 nm in diameter and ranged in length from 86-726 nm due to processing. Due to the unique adhesive and structural properties of nanofibers, we concluded that these fibers may play a role in platelet aggregation, leading to clotting, and the sealing of wounds.
云南白药是一种传统的中草药，已经有超过 100 年的历史用于治疗伤口。在这里，我们使用原子力显微镜（AFM）来确定云南白药的纳米结构。AFM 图像显示，在该药物的溶液中存在均匀的纳米纤维，且含量相对较高。由于加工的原因，纤维的直径通常为 25.1nm，长度范围为 86-726nm。由于纳米纤维具有独特的粘附性和结构特性，我们得出结论，这些纤维可能在血小板聚集中起作用，导致凝血和伤口的密封。
