Background: The advancing etiopathogenesis, diagnosis, and treatment of the global coronavirus disease 2019 (COVID-19) pandemic have prompted the medical community to consider Ayurveda, Siddha, and Unani as add-on preventive and therapeutic options. Objective: To explore the effect of standalone or integrative Traditional Formulations (TFs) on selected clinical symptoms and biomarkers of COVID-19. Search strategy: Out of 465 articles identified from PubMed, ScienceDirect, and Scopus, 17 randomized controlled trials (RCTs) with 1646 COVID-19 patients published from January 2020 to February 2022 were included in the study. Inclusion criteria: RCTs that compared the effect of standalone/integrative TFs in decoction, tablet, and powder forms with placebo plus standard care (SC)/placebo/SC as controls involving mild to severe symptomatic COVID-19 patients were included. Data extraction and analysis: Three reviewers independently assessed the titles and abstracts of each article based on the inclusion after deleting duplicates. The relevant full texts were retrieved and examined, and then their data were extracted and double-checked by three independent reviewers using prepared data extraction forms. The primary outcome variables were reverse transcription polymerase chain reaction, fever, cough, dyspnea, myalgia, headache, C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), and D-dimer. Results: The effect of different TFs or integrative TFs was more to inhibit severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) than the controls. There was an increase in fever and cough, a decrease in dyspnea, myalgia, headache, and ESR, no change in CRP, and a slight increase in D-dimer as an effect of TFs. Conclusions: Integrative or standalone TF may be the inexpensive preventive and therapeutic option to inhibit SARS-CoV-2 and its clinical symptoms. [ABSTRACT FROM AUTHOR]
