Research progress in mineral Chinese medicine realgar / 中国中药杂志

ABSTRACT

Realgar is a mineral traditional medicine with definite efficacy. The function of realgar is detoxicating, insecticiding, eliminating dampness and phlegm, etc. It is widely applied in clinical practice by compatibility medicines. However, the safety and scientificalness of clinical application are questioned because of the toxic effect caused by arsenic compounds. At present, there are still many problems in the research of realgar, which are mainly manifested in three areas: the expression of main components and effective substances are inconsistent; the anti-tumor mechanism is difficult to explain at the molecular level; the mechanism of compatibility is not clear. As a result, realgar and realgar-containing Chinese patent medicines are frequently prohibited from entering the international market, and the reputation of traditional Chinese medicine is also damaged. This paper would analyze the research status of realgar at home and abroad as well as its problems from its main components, effective substances, anti-tumor mechanism and compatibility mechanism. In view of these difficulties, quantum chemical calculation method is proposed to solve them, so as to make up for the shortcomings and limitations of experimental technology and experimental conditions, reduce the cost of realgar research and improve research efficiency. Moreover, it provides inspiration for research of other mineral medicine.
