Chinese Medicine for Coronavirus Disease 2019 (COVID-19): A GRADE-Assessed Systematic Review and Meta-Analysis.

Coronavirus disease 2019 (COVID-19) has caused enormous public health and socioeconomic burden globally. This study aims to evaluate the efficacy and safety of Chinese medicine (CM) against COVID-19. Eleven databases were searched on April 30, 2021, and 52 studies were included. The RoB 2.0, ROBINS-I, and GRADE tools were employed to assess the risks and evidence grades. The findings with moderate certainty in GRADE showed that compared with routine treatment (RT), Lianhua Qingwen granules (LHQW) adjunctive to RT showed significantly improved efficacy rate (relative risk (RR) = 1.19, 95% confidence interval (CI): [1.09, 1.31]), febrile score (standard mean difference (SMD) = -1.21, 95% CI: [-1.43, -0.99]), and computerized tomography (CT) lung images (RR = 1.23, 95% CI: [1.10, 1.38]); Qingfei Paidu decoction (QFPD) plus RT significantly shortened the length of hospital stay (SMD = -1.83, 95% CI: [-2.18, -1.48]); Feiyan Yihao formula (FYYH) plus RT significantly improved the clinical efficacy rate (RR = 1.07, 95% CI: [1, 1.15]), febrile time (SMD = -0.02, 95% CI: [-0.23, 0.19]), and time to negative PCR test for COVID-19 (SMD = -0.72, 95% CI: [-0.94, -0.51]). Adjunctive effects of CM with lower certainty of evidence were found, including the improvements of symptoms, laboratory findings, and mortality. No or mild adverse events were observed in most of the studies. In conclusion, the current evidence indicates that CM formulae, particularly LHQW, QFPD, and FYYH, have adjunctive effects on the standard treatment of COVID-19.

HerBChain, a blockchain-based informative platform for quality assurance and quality control of herbal products.

The use of medicinal plants is popular worldwide. Correct herbal authentication is of paramount importance to the safety and best interest of consumers. On the market, there is no comprehensive blockchain-based system to track the processes from plantation to manufacturing and to the sale. With the advancement of information technology, an open and transparent blockchain-based platform, HerBChain, was created to enhance the quality control of herbal products. The implementation of blockchain technology is to minimize the manipulation of recorded information. HerBChain is an information platform for recording the six important processes of herbal product manufacturing and marketing, which include plantation base, TCM processing factory, TCM manufacturer, testing laboratory, distributor and retailer. By duly recording the parameters and data essential for product quality in manufacturing and supply chain, the traceability and reliability of the products can be ensured.
