A systematic review with a meta-analysis on the use of Chinese herbs for COVID-19, involving 732 participants, reported that the combination of Chinese herbs and standard care has a superior effect on changes in symptoms and the sign core (− 1.30 by SMD, 95% CI [− 2.43, − 0.16]; three studies; n = 261, P = 0.03) and inflammatory marker C-reactive protein (CRP, mg/L; −11.82 by MD, 95% CI [− 17.95, − 5.69]) and suggested that Chinese herbs, as an adjunct treatment, with standard care can help improve treatment outcomes in COVID-19 cases [36]. Here, CRP is linked to COVID-19.
