COVID-19 has emerged as the most dangerous global pandemic threat since its outbreak during December 2019 in Wuhan, China. As of August 12th, 2020, the World Health Organization (WHO) has reported more than 19 million confirmed cases and 7.3 lakhs deaths worldwide and it has spread to 216 countries, areas or territories . Now, it is a big challenge for the researchers and health professionals to find out a solution for this deadly viral infection. COVID-19 is a viral infection that has been known to have the fastest frequency of replication in its positive strand resulting in the quick formation of new progeny viral cells inside the host cells. It has also been reported that SARS-CoV-2 has a high rate of mutagenesis and deviations in structure, which has formed a barrier for therapeutic procedures [2,3]. In Ayurveda point of view, COVID-19 is a Janapadodhwamsa vikara (epidemic disease), a situation where the environment – air, water, land and seasons – is vitiated, causing a simultaneous manifestation of a disease among large populations .
Medicinal plants have been used as a treatment and preventive strategy for several infectious diseases since ancient times. The advantage of using these herbs in viral respiratory infections is to build immune stimulating and inflammation modulating effects to prevent the severe life threatening conditions. Holistic approach of Ayurveda focuses on prevention of diseases through lifestyle modification, dietary management, prophylactic interventions for improving the immunity and managing the symptoms using herbal preparations. Medicinal plants have been reported to have antiviral activity and many species such as Aegle marmelos, Andrographis paniculata, Acacia nilotica, Ocimum tenuiflorum, Piper nigrum, Solanum nigrum, Terminalia chebula etc. have been scientifically proved for their anti-viral properties [5-7]. Ayurveda medicines were recommended by Ministry of AYUSH, Government of India to enhance the immunity and to prevent the severe conditions of Cov-2 infection. Detailed guidelines have been published by the AYUSH ministry regarding the management of Covid-19. About 80% of COVID-19 cases are with mild symptoms requiring only primary medical care, 15% require urgent medical attention at secondary health care services and remaining 5% are life-threatening cases requiring an intensive care and hence require a transfer to tertiary health care units equipped with ICU. Ayurveda medicines are advised to patients with mild symptoms and those under surveillance which addresses the therapeutic province within an integrative model of care .
