BackgroundThroughout the classical era, medicinal plants have already been employed as a resource for medicine and in the healing of wounds. Chronic wounds are linked to significant healthcare and socioeconomic consequences despite standard medication. The development of effective wound‐healing therapies with improved wound repair mechanisms may result from the emergence of innovative wound‐healing techniques utilizing medicinal plants in combination with nanotechnology. This review combines herbal formulations like biodegradable nanoparticles, films, fibres, hydrogels, and ointments with antibacterial, antioxidant, and anti‐inflammatory characteristics with herbal medicines to promote wound healing.ObjectiveThis article aims to provide an overview of the numerous cellular and molecular elements involved in skin healing.FindingsThis article overviews the numerous cellular and molecular elements involved in skin healing. Following the commencement of a tissue lesion, a series of molecular and cellular actions take place to restore the injured tissue. This process is known as regeneration and tissue repair. Sequential events involving the integration of dynamic processes involving soluble mediators, blood cells, and parenchymal cells result in the exudative, proliferative, and extracellular matrix remodelling stages.ConclusionThe development of tissue edema is aided by exudative processes after damage. By recruiting myofibroblasts and fibroplasia, the proliferative stage aims to decrease the area of tissue damage. The mechanisms of angiogenesis and re‐epithelialization are still observed at this point.

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.

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.
