Abstract  Objective: Search the "real world" case reports of Houttuynia cordata Thunb (HCT)-associated adverse drug reactions (ADRs) to systematically mine potential ADRs of HCT and further investigate whether HCT contained preparations could cause aristolochic acid nephropathy or cancer. Methods: PubMed, EMBASE, Science Direct, Scopus, Web of Science, and CNKI, Wanfang, VIP, Sinomed databases were searched from databases setup to 1st January 2019. All case reports using HCT contained preparations were pooled according to inclusion and exclusion criteria. 15 items in case reportes including basic informations of studies/patients, characters/treaments of ADRs were extracted and analyzed. Results: A total of 346 case reports (441 patients) on the use of different preparations of HCT were finally pooled, among which 89 articles (117 patients) just presented efficacy reports without ADRs and 257 articles (324 patients) on the HCT-related ADRs were further analyzed. ① HCT in vivo injections were recorded in 265 articles (338 patients) including 249 ADR reports (315 patients) and 16 efficacy reports (23 patients). As for the ADRs reports, allergic reaction was the major ADRs with different symptoms and onset time. The worst consequences were anaphylactic shock (116/315) and death (11/315), followed by dyspnea (228/315), change of complexion (181/315), heart of abnormality (180/315), chest tightness (147/315), cyanosis (142/315) and so on. The fast onset time was 10 seconds and the most ADRs happened in 30 minutes. Dexamethasone was the mainly medication to treat ADRs. ② Oral HCT agents were descripted in 75 articles (94 patients) including 8 ADR reports (9 patients) and 67 efficacy reports (85 patients). Among the 8 ADR reports, 8 patients used Chinese patent medications contained HCT and only 1 patient used HCT decoction. The ADRs almost manifested as skin symptoms, including rubella, macula, rash and urticaria.③HCT external preparations reported in 6 articles (9 patients), none of those presented any ADRs symptoms. ④ No case was found to develop cancer, aristolochic acid nephropathy, interstitial nephritis, renal interstitial fibrosis or renal failure due to HCT preparations. Conclusion: The HCT-related ADRs were mostly caused by its processed preparations, including HCT injections and patent preparation. The oral HCT agents as docoction rearly caused ADRs. There were no reports of aristolochic acid nephropathy or cancer cases caused by HCT.
