Ophiocordyceps sinensis and Cordyceps militaris both contain many bioactive compounds that confer potential therapeutic benefits. This review discusses the possible use of cultivated C. militaris as an effective substitute for native O. sinensis in the face of ever-increasing prices of O. sinensis because of its short supply. On the one hand, cultivated C. militaris contains higher levels of cordycepin when compared with that of wild-type O. sinensis and cultivation of C. militaris has been shown to be capable of reducing the risk of heavy metal contamination. On the other hand, there is a paucity of robust in vivo studies and randomized controlled tests comparing the pharmacology and use of C. militaris and O. sinensis. For extraction of cordycepin as western-style tablets, the use of cultivated C. militaris rather than O. sinensis represents the most appropriate future approach. For many other purposes, comparative pharmacology and clinical trials are in urgent needs. 展开更多

Acute kidney injury(AKI) is a major health threat worldwide. The literature on herbal intervention in AKI was searched from English and Chinese databases and reports were critically analyzed in terms of preventing AKI, promoting repair and regeneration, enhancing extrarenal clearance of uremic toxins, and preventing progression to chronic kidney disease(CKD). Altogether, 16 herbal formulae and a few extracts derived from individual herbs were reported to prevent or mitigate AKI in animal models induced by renal ischemia/reperfusion, cisplastin,gentamicin, glycerol, adenine, sepsis or physical exhaustion. Four formulae and six individual herbs were reported to accelerate recovery and/or to prevent CKD in established AKI animal models. Intrarectal herbal medicines, with or without simultaneous oral administration, were reported in six clinical trials and in an animal model to increase extrarenal clearance of uremic toxins. Additional 13 clinical trials reported oral or intravenous herbal interventions in AKI of different etiologies. Despite recurring problems, notably poor compliance with good practice guidelines for clinical trials and for authentication, naming and quality control of herbal materials, accumulating experimental data on the preventive effects of herbal medicines in AKI look encouraging and urge for better, definitive trials to guide clinical practice. Herbal enemas promoting extrarenal clearance of uremic toxins seem cost-effective, but better clinical evidence is certainly needed before any affirmative recommendation be made for AKI patients without access to dialysis. New frontiers, however, lie in those herbal remedies that promote repair/regeneration and prevent chronicity after AKI. Recent experimental data suggest that this may be possible. 展开更多

Criteria for diagnosing nephropathy and urothelial neoplasms induced by botanicals containing aristolochic acids(AAs) are well established. Highlights of recent research on AAs include mechanisms of AA intrarenal transport and metabolism and vigorous debate on whether AAs may also cause liver cancers. Many other botanicals may also cause renal injury, but a generalized framework for diagnosing botanical-induced kidney injury(BIKI) is lacking. Based on what we have learnt about the wide spectrum of phenotypes of BIKI attributed to AAs and a recently published standardized phenotypic framework of drug-induced kidney disease, we propose that BIKI may be categorized into six phenotypes(acute kidney injury, tubular dysfunction, glomerular disorders, nephrolithiasis, chronic kidney disease, and neoplasms) and four mechanistic types(A, predictable;B, idiosyncratic;C, chronic;and D, delayed). We call for international cooperation assembling a task force to develop, refine, and regularly appraise an online BIKI database, documenting botanical use, phenotypes, mechanisms, and levels of evidence. Once established, such a database may be linked with electronic patient records and pharmacovigilance channels to generate alerts, guide clinical decision-making, direct future research, and support evidence-based regulation of herbal medicines and education of healthcare professionals and the public. Finally, to prevent BIKI, we propose that a proactive approach integrating the triad of botanicals, users, and stakeholders will be needed. 展开更多
