“…Several herbal/traditional medicines have been investigated for the treatment of mild and severe/critical COVID‐19. They come from countries with well‐known traditional medicine such as China (Xia et al, 2021 ; Xiao et al, 2020 ; Xu et al, 2021 ; Zhang et al, 2021 ; Zhou et al, 2021 ), India (Devpura et al, 2021 ; Natarajan et al, 2021 ; Srivastava et al, 2021 ), and Iran (Karimi et al, 2021 ; Valizadeh et al, 2020 ). These studies showed that herbal medicines could reduce SARS‐CoV‐2 viral load, hospital length of stay, time to symptom resolution in mild COVID‐19 patients, and mortality rate in patients with severe/critical COVID‐19, when compared with placebo.…”
