The study revealed that various extracts of Artemisia annua and Artemisia afra have potential antiviral activities against SARS-CoV-2. However, the scientists mention that further studies are required to check whether appropriate serum levels of Artemisia compounds needed to inhibit SARS-CoV-2 can be achieved in patients. Moreover, further animal and human clinical trials are required to determine whether these in vitro observations can be translated for actual clinical use.
Also, a new study in shown that nutritional supplements, including several vitamins and the mineral zinc, could be useful in preventing the infection or reducing its severity if caught.
