A good job of pharmacovigilance of Chinese materia medica not only helps Chinese pharmaceutical companies to control their risks, but also guides them to use drugs safely and rationally. And it is also of great significance to the national drug regulatory work. Based on the monitoring of herbal safety in WHO pharmacovigilance system, the establishment of a Chinese materia medica pharmacovigilance system was explored in order to provide a valuable reference for the risk control of Chinese pharmaceutical companies, the clinical use of Chinese materia medica, and the national drug regulatory work.展开更多

In abroad, attention has been mainly payed to raising antisera and monocolonal antibodies against the endotoxin and the induced mediators. However, the allergic reactions and the cost are still the problems. Till now, there is no drug that can antagonize endotoxin with high effectiveness and low toxicity. Clinical treatments are still confined in inhibiting or killing the pathogen, and correcting the internal environmental disturbance. Being less toxic and rich in resources with low cost and less side-effects, screening of effective Chinese drugs for antagonizing endotoxin is of important and practical significance. Endotoxin belongs to the category of toxic evils, or more precisely, the heat toxin in TCM. Therefore the application of heat-clearing and detoxifying Chinese drugs to antagonizing endotoxins is consistent with the theory of TCM. Some achievements in this field are reported as follows.展开更多

It refers to study on the toxicological features of a constructed network model which is used to analyze toxic substances and their interaction and regulation in biological systems, particularly investigate the toxic effects of drugs and/or compatibility of medicines on body, and clarify the mechanism of toxicity. Network toxicology currently develops rapidly in safety prediction of Chinese materia medica （CMM）. The application of network toxicology to safety and toxicology study on CMM is extremely beneficial to identify the toxic components and potential incompatibility of CMM. Since CMM is a complex system with multi-components, multi-targets, and multi-interactions, the network toxicology in safety prediction of CMM faces three great challenges, including integration studies of bioinformatics, innovation of methods, and tools and risk assessment in future development of the network toxicology in CMM research. In this paper, relevant database, approaches and tools that network toxicology utilized in the safety study of CMM were carefully reviewed. Based on the progress made, the scientific development and modernization of CMM will be greatly enhanced.展开更多

In this review, the toxicity of CMM and the toxicity classification of CMM were introduced. And traditional TCM theory and methods particularly used for control and attenuation of CMM's toxicity were described in detail. The traditional processing technology and CMM drug combination were most important detoxifying measures used in CMM formulation and clinical practice. Finally, some factors that have influence on occurrence of CMM's toxicity were discussed such as different species, producing technology and so on.展开更多
