The dried roots of Aconitum pendulum Busch are the major source of a commonly used Tibetan medicine,namely Tiebangchui(TBC)(Fig.S1).However,raw TBC contains a large amount of high toxic diester-diterpenoid alkaloids(DDAs),and the improper use would cause arrhythmia,irreversible cardiovascular damages,and even death.“Paozhi”,an appropriate processing method,is the essential prerequisite for the safe clinical application of ***-decocting and sand-frying are commonly used processing methods for toxicity attenuation and efficacy preservation for TBC.

The discovery and synthesis of MnBi2Te4in 2013 initially garnered little attention [1]. Yet, the revelation of its topological properties in 2019 [2–6] sparked a surge of research into the MnBiTe family. These extensive studies are primarily driven by two objectives:the realization of a high-temperature quantum anomalous Hall effect （QAHE） and the exploration of exotic phases born from the interplay of topological and magnetic orders,
