The outbreak of novel coronavirus (nCoV) or severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) in December 2019 in Wuhan, China, has posed an international public health emergency worldwide and forced people to be confined in their homes. This virus is of high-risk category and is declared a pandemic by the World Health Organization (WHO). The worldwide researchers and various health professionals are working together to determine the best way to stop its spread or halt this virus's spread and circumvent this pandemic condition threatening millions of human lives. The absence of definitive treatment is possible to explore to reduce virus infection and enhance patient recovery. Along with off-label medicines, plasma therapy, vaccines, the researchers exploit the various plants/herbs and their constituents to effectively treat nCoV infection. The present study aimed to present brief and most informative salient features of the numerous facts regarding the SARS-CoV-2, including the structure, genomic sequence, recent mutation, targeting possibility, and various hurdles in research progress, and off-labeled drugs, convalescent plasma therapy, vaccine and plants/herbs for the treatment of coronavirus disease-2019 . Results showed that off-labeled drugs such as hydroxychloroquine, dexamethasone, tocilizumab, antiviral drug (remdesivir, favipiravir), etc., give positive results and approved for use or approved for restricted use in some countries like India. Future research should focus on these possibilities that may allow the development of an effective treatment for COVID-19.

Gastrointestinal (GI) and biliary disorders are the most commonly known health issues for people in the present time as a consequence of modern lifestyle, eating habits, stress, and many other conditions. The usage of traditional substances has been phased out over time, resulting in an increase in the occurrence of numerous diseases and a decrease in immunity. Therefore, in the current scenario, traditional medicine is increasingly being used to treat and manage diseases worldwide. Traditional medical systems of India, China, and Africa are the most frequently used today. Indian medicinal system includes the Ayurveda, Siddha, and Unani systems of medicine. Ayurveda is the most antique system of medicine, which relies on the usage of plant-based formulations. Herbal medicines are used nowadays by up to half of the world's population. Phytomedicines isolated from plants contain a wide variety of bioactive components that can have both negative and positive effects. Many herbal plants, such as Acacia, Aloe, Carum, Rose, Funnel, etc., are proven to be effective as phytomedicines that are effective for the cure of gastrointestinal and biliary problems. The available pharmacological therapeutic drugs often have efficacy but are associated with many adverse effects. To minimize the adverse effects, the use of phytomedicines can be the best possible alternative. In this study, a review of some of the most frequently used traditional herbal medicine isolates with their proven pharmacological activity and novel drug delivery systems for the proper delivery of isolates is presented. Moreover, currently available herbal-marketed formulations are also highlighted.

Novel coronavirus disease (COVID-19) has been spread in 213 countries and created an emergency situation in around the world. Coronavirus is a group of single-stranded RNA enveloped virus which causes severe respiratory infection in the infected individual. Nowadays, coronavirus has become a leading cause of death in the world. Efficient diagnosis is an essential step before starting the best possible treatment. For the diagnosis of coronavirus mainly 3 methods are reported such as RT-PCR method, Regular LAMP-based methods and Serology based tests. Based on the above methods, various diagnostic kits has been developed by different countries. This review contains the list of diagnostic kits approved by various countries, their working mechanism and time taken to give result along with sampling procedure and major precautions which is most important during the diagnosis process. The worldwide R & D (research and development) will definitely lead to find an efficient and rapid diagnostic tool for the treatment of COVID-19.

: The novel coronavirus severe acute respiratory syndrome Corona Virus-2 (SARS-CoV-2) has become a pandemic, as declared by WHO in March 2020 producing the deleterious effects to patients worldwide. The angiotensin-converting enzyme-2 (ACE-2) has been recognized as the co-receptor for SARS-CoV-2 infections and may acts as a therapeutic step in blocking the enzyme to reduce SARS-CoV-2 expression and further cellular entry. Presently, the role of ACE-2 in coronavirus disease 2019 (COVID-19) infection has been known and the experts have started working on the enzyme ACE-2 for the management and treatment of this pandemic disease. The binding of spike (S) protein of SARS-CoV-2 to these receptors is the most important step and plays a key role in viral replication, thus this enzyme is becoming the doorway for the entry and spread in the human body causing asymptomatic pneumonia and severe of which is leading to death. As no specific method to prevent and treat this disease is available, the use of ACE-2 as a targeting ligand with COVID-19 virus spike protein could be helpful in the proper management of SARS-CoV-2 pneumonia.
