There is no evidence of the effectiveness of Banlangen for novel coronavirus pneumonia. As a proprietary Chinese medicine preparation, Panax quinquefolium can inhibit viruses and prevent infections to a certain extent, but there is no evidence that Panax quinquefolium has an inhibitory effect on the new coronavirus pneumonia, so the use of Panax quinquefolium for the prevention of the new coronavirus pneumonia is not recommended. For suspected patients, self-administration of Banlangen for treatment at home is not recommended. It is recommended that patients with fever and history of exposure go to hospitals for standardized consultation, and receive isolation and standardized treatment in designated hospitals after a clear diagnosis.
