Covid-19 (Coronavirus disease 2019) is an infectious disease with clinical symptoms like fever, sore throat, sneezing, shortness of breath, fatigue, cough, diarrhoea, chills, and respiratory symptoms that has now entered into the new dangerous phase.

Till 7Nov 2020, the total number of confirmed COVID-19 cases was 48534508, and the death number is 1231017, affecting, directly and indirectly, more than 215 territories worldwide. Hence an effective international strategy is required to control and prevent this disaster. To combat the coronavirus-2 different approaches have been initiated in scientific concern, but focussed attention should be given to the medical value of herbal plant extract to prevent these endemic type diseases. Hence, this review describes the symptoms and the role of herbal plants in treating the COVID-19.
