World Health Organization (WHO) on February 11, 2020 named the infection as COVID-19 as an acronym for 'coronavirus disease-2019' and on March 11, 2020 declared the outbreak as pandemic. It affects all the people without discrimination, however, older, immune compromised are more susceptible. The virus chiefly spread through droplet infection from infected person to healthy one by coughing, sneezing or with infected hands when touched to eyes, nose or mouth. Symptoms of the infection range from mild to severe ones. In severe cases (approx. 14% of cases) fever typically of high grade (104oF), breathlessness, pneumonia and severe acute respiratory syndrome may appear. So far no specific treatment or vaccine for novel coronavirus-2019 is there. From the past and recent past experiences we have learnt that herbal medicines have proven beneficial against various dreadful viral infections.
