A Traditional Medicine, Nigella Sativa Can Be Effective on Novel Coronavirus (Sars-Cov-2) and Pulmonary Diseases (Hypothesis)

In late December 2019, a group of patients applied to hospitals with a diagnosis of pneumonia with an unknown etiology in Wuhan, China. The pathogen, novel coronavirus SARS-CoV-2 was detected by local hospitals using a monitoring mechanism for “pneumonia of unknown etiology”, which was established to identify new pathogens in a timely manner after the 2003 SARS outbreak. Nigella sativa is an annual herb. Nigella sativa has been considered for treatment of various diseases and is one of the most widely investigated herbs. In this review, we will especially focus on the antibacterial, antiviral effects of Nigella sativa. Most importantly, we aimed to review whether it is effective against the current SARS-CoV-2 (COVID19), and against bacterial and viral superinfection accompanying this virus, and whether it can be effective in the treatment of SARS-CoV-2 related lung diseases.
