“…Herbs, natural drugs or related analogs are important alternative therapies in the prevention, treatment, and recovery from the infection. The mortality rate was found to be lower in patients treated with oseltamivir, an anti-influenza drug synthesized using two natural products, quinic acid and shikimic acid, than in the control group (1.7% vs. 6.7%, p = 0.06), and the administration of oseltamivir was associated with a shorter length of hospital stay and earlier recovery/discharge from hospital [ 90 ]. A number of natural compounds have proven to have anti-human coronavirus activities [ 91 , 92 , 93 ], and certain combinations of herbs are effective to prevent the infection and relieve the associated symptoms, but further research on natural products to identify more potent new leads is urgently needed.…”
