COVID-19, caused by the severe acquired respiratory syndrome coronavirus-2 (SARS-CoV-2), is a highly contagious disease that has emerged as a pandemic. Researchers and the medical fraternity are working towards the identification of anti-viral drug candidates. Meanwhile, several alternative treatment approaches are being explored to manage the disease effectively. Various phyto-drugs and essential oils have been reported to have antiviral activity, but this has not been well studied in the context of SARS-CoV-2. The main focus of this review is on the biology of infection and the different therapeutic strategies involved, including drug repurposing and phytopharmaceuticals. The role of phytochemicals in treating COVID-19 and various other diseases has also been emphasized.
