Toxicity-attenuating compatibility is an effective measure to ensure the safety of Chinese medicine. Involving the origin, processing method, compatibility mode, and dosage, it faces multiple challenges, such as the uncertainty of toxic substances, toxicity latency, indefinite safe dose, complex toxicity-efficacy relationship, and individual difference. As a result, research on clinical safety of Chinese medicine is limited by the consistency at "molecular-cellular-organ-overall" levels, unclear interaction of multiple medicinals and multiple substances, the "toxicity-efficacy-compatibility-syndrome" correlation, and the "dosage-time-toxicity-efficacy" conversion law. Therefore, following the principle of "starting from the clinical practice, verifying via the theoretical basis, and finally applying in clinical practice", we verified the toxicity at "molecular-cellular-organ-overall" levels, revealed the interaction of multiple medicinals and substances, collected evidence at multiple levels, clarified the "dosage-time-toxicity-efficacy" relationship, and tested the consistency between basic and clinical biomarkers. On this basis, we studied the toxicity-alleviating and efficacy-enhancing(preserving) compatibility characteristics, the fate of one medicinal and multiple medicinals in vivo, the molecular mechanism of toxicity, the "dosage-time-toxicity-efficacy" conversion law, and the clinical characteristics of toxic traditional Chinese medicine based on disease and syndrome. The three mechanisms of toxicity-attenuating compatibility reflect the seven-reaction theory in Chinese medicine compatibility. Finally, the strategies for safe use of Chinese medicine were proposed.

To provide the basis for the future research on the nephrotoxicity of Chinese herbal medicine through systematic and comprehensive summary of all the Chinese herbal medicines which may lead to nephrotoxicity. Foreign resources included PubMed and Cochrane library， and domestic research resources was China Food and Drug Administration(CDFA) Adverse Drug Reaction Monitoring Center database. The databases were searched from establishment to January 1， 2017. There was no limitation on research type. 28 English studies were found， including 97 Chinese herbs or prescriptions with the risk of nephrotoxicity. The following six Chinese herbal medicines with the risk of nephrotoxicity had a large number of studies： aristolochic acid(5 studies)， Tripterygium wilfordii(4 studies)， Erycibe obtusifolia(2 studies)， Rheum palmatum(2 studies)， Ephedra sinica(2 studies)， and Atractylodes lances(2 studies). The remaining 91 Chinese medicines were reported with risk of nephrotoxicity in only 1 study respectively. CDFA reported 16 Chinese herbal medicines with the risk of nephrotoxicity， including Ganmaoqing Pian(capsule)， Zhenju Jiangya Pian， T. wilfordii preparation， Vc-Yinqiao Pian， Chuanhuning injection， Shuanghuanglian injection， Qingkailing injection， Lianbizhi injection， herbal decoction containing Aristolochiae Radix， Guanxin Suhe Wan， Shugan Liqi Wan， Ershiwuwei Songshi Wan， herbal decoction containing Aristolochia Fangchi， herbal granules containing root of Kaempfer Dutchmanspipe， Ganmaotong(tablets)， and Longdan Xiegan Wan. Currently， in addition to aristolochic acids， the most reported Chinese herbal medicine with the risk of nephrotoxicity is T. wilfordii preparation.

This study systematically searched CNKI and Web of Science(WoS) for the research papers on the toxicity of Tripterygium wilfordii included from database inception to August 31, 2021, and visually displayed the authors, research institutions, keywords, and other contents using bibliometrics and CiteSpace 5.8.3. Furthermore, the current situation and research progress on T. wilfordii safety were also analyzed based on information extraction to find the research hotspot, evolution path, and development trend, and to provide references for future research. A total of 1 876 Chinese papers and 243 English papers were included in the study. The analysis of authors showed that WANG Qi and ZHANG Luyong had the most publications in Chinese and English papers, respectively. According to the analysis of research institutions, National Institutes for Food and Drug Control and China Pharmaceutical University possessed the largest number of Chinese and English papers, respectively, but there was less cooperation between them. The analysis of keywords in Chinese and English papers showed that the research contents of the safety of T. wilfordii mainly focused on clinical monitoring, mechanism, dosage form improvement, quality standard, component analysis, monomer research, efficiency and toxicity reduction, etc. Metabonomics, tripterine, and the underlying mechanism of toxicity were the research hotspots in the future. At present, the research on the toxicity of T. wilfordii is still under development. It is necessary to highlight the in-depth research and strengthen the inter-group and inter-region cooperation of authors or institutions to provide references for the research on the toxicity of T. wilfordii.

As a most important Chinese materia medica, Aconiti Lateralis Radix Praeparata(Fuzi) had been widely used in China for thousands of years. This herbalogical study was systematically performed based on variation characteristics of the naming, habitat, harvesting, processing and properties. The sharp toxicity of Fuzi had been well known since the spring and autumn period in the history, which was much earlier than that its medical properties was understood and applied. Sichuan province was regarded as the geo-authentic region of Fuzi all along, where the best quality goods could be provided for clinic use. The study showed the harvesting time of Fuzi was changing in different periods, and the possible effects were of climate change and artificial planting. The perishable characteris-tics of Fuzi severely limited its storage period; therefore, different kinds of storage methods were effectively used since Tang Dynasty. For thousands of years, Fuzi had been processed with various accessories to reduce toxicity, while simultaneously the study on processing mechanism was on going all the time. Fuzi was widely used in clinical practice to cure Yang depletion syndrome, which was based on its function of enhancing Yang and removing cold. Along with the further study on quality evaluation standard, Fuzi will probably get a much wider range of applications.

A total of 33 pesticides have been banned from Chinese medicinal materials and decoction pieces(plants) according to Chinese Pharmacopoeia(2020 edition). According to the chemical structures, they are mainly divided into seven categories: organophosphorus compounds, organochlorines, carbamates, amidines, sulfonylureas, phenylpyrazoles, and ethers. These banned pesticides exhibit neurotoxicity, reproductive toxicity, immune system toxicity, teratogenicity, carcinogenesis, and mutagenesis, seriously damaging human and animal health. They affect not only the quality and safety of traditional Chinese medicines and resulting products, but also their competitiveness in the international market. Due to the numerous varieties of traditional Chinese medicines and their complex substrates, it is necessary to establish a universal and highly sensitive method for pesticide residue detection. This review systematically summarized the residual status, toxicity, and analytical methods of banned pesticides in traditional Chinese medicines, and forecasted the prospects of different analytical techniques, so as to provide reference for further safety and risk assessment of banned pesticide residues in traditional Chinese medicines, thus ensuring the safe production of traditional Chinese medicines.
