Objective: The present study aimed at evaluating the effect of combination of medicinal plants, including Colchicum autumnal L., Olea europaea L., Nigella sativa L., Lavandula angustifolia L., and Zingiber officinale Roscoe, on the recovery and outcome of COVID-19 patients. Materials and Methods: This study was conducted on 150 COVID-19 patients. All patients received both pharmaceutical and supportive treatments. In addition to the standard care treatment, intervention group received two capsules of herbal medicine orally every 8 hours, while control group received placebo. Results: Oxygen saturation percentage (SpO2) of the intervention group (median:88.00) was significantly higher than that of the control group (median:86.00), while C-reactive protein (CRP) of the intervention group (median:20.00) was significantly lower than that of the control group (median:28.00) at the time of hospital discharge (p<0.05).
Conclusion: The combination of studied medicinal plants could significantly reduce the oxygen requirement and oxygen therapy.
