The COVID-19 pandemic, caused by the SARS-CoV-2 virus, has an urgent need for effective therapeutic agents. In this regard, phytochemicals, bioactive compounds derived from plants, have emerged as potential candidates for the treatment and prevention of COVID-19. This review explores various facets of phytochemical research in relation to COVID-19, ranging from their identification to future perspectives in their application. It sets the stage, describing their nature, classification, and historical use in traditional medicine, alongside their recognized health benefits. We then delve into the methodologies for phytochemical screening, highlighting advanced techniques such as high-performance liquid chromatography (HPLC) and spectroscopic methods, which are pivotal in identifying and characterizing these compounds. In addition, focusing on potential phytochemicals against SARS-CoV-2, we discuss compounds like flavonoids, terpenoids, and alkaloids, which have shown promise in preliminary studies for their antiviral properties. However, the transition from laboratory findings to clinical applications faces challenges, such as issues of bioavailability, lack of clinical trials, and the complexity of phytochemical interactions. Advancements in nanotechnology for drug delivery, exploration of synergistic effects, and personalized medicine are crucial. Therefore, this review underscores the importance of integrating traditional knowledge with modern scientific studies and highlights the need for inclusive clinical studies to validate the efficacy and safety of phytochemicals. The promising yet challenging path of phytochemical research offers a hopeful path in the ongoing battle against COVID-19 and future pandemics.
